<p>In addition to the enormous scientific potential, another major innovation of the observatory is its strong commitment to environmental respect and project sustainability. From the initial design phases, <a href="https://www.atlast.uio.no/design-study/wp5-energy/index.html" target="_blank" rel="noreferrer noopener">hybrid energy systems</a> based on renewable fuels are being proposed, and <a href="https://arxiv.org/abs/2404.17311" target="_blank" rel="noreferrer noopener">energy recovery mechanisms</a> are being developed to minimize the infrastructure’s energy consumption during operation. Furthermore, a distributed and remote operation plan is being considered, which will significantly reduce the need for staff to travel regularly to the telescope in the remote Atacama Desert, providing environmental, safety, and work-life balance benefits.</p></div>

			<h3><strong>160 investigadores de 60 universidades presentan los resultados de su primer conjunto de simulaciones cosmológicas de la formación de una galaxia como la nuestra, la Vía Láctea,</strong> <strong>con el fin de avanzar hacia una teoría de la formación de las galaxias.</strong></h3>
<h3><strong>El equipo de investigación ha revelado cómo la recuperación de las propiedades observadas del gas que rodea a las galaxias es la clave para obtener simulaciones realistas, en lugar de ajustar el número y la distribución de las estrellas, que era lo habitual hasta ahora.</strong></h3>
<p>En la última década, los astrofísicos han desarrollado herramientas que les permiten simular cómo se formaron las galaxias desde el Big Bang, hace 13.800 millones de años, hasta hoy con ayuda de superordenadores, pero siempre se veían limitados por diversas fuentes de error. Ahora, <strong>un grupo internacional de investigación, dirigido por Ji-hoon Kim en la Universidad Nacional de Seúl (Corea), Joel Primack en la Universidad de California Santa Cruz, y Santi Roca-Fàbrega colaborador honorífico del grupo GUAIX de la Universidad Complutense de Madrid </strong>(actualmente en la Universidad de Lund), ha encontrado la forma de subsanar estos errores y realizar simulaciones más acertadas.</p>
<p>En los últimos años se han realizado grandes progresos en las<strong> simulaciones por ordenador, lo que ha permitido a los investigadores calcular de forma realista cómo se forman las galaxias.</strong> Estas <strong>simulaciones cosmológicas son cruciales para nuestra comprensión teórica del origen de las galaxias, las estrellas y los planetas. </strong>Sin embargo, las predicciones de estos modelos se ven afectadas por las limitaciones de la resolución numérica y las suposiciones sobre una serie de factores, como la explosión de estrellas, los flujos galácticos y los movimientos estelares.</p>
<p>Para minimizar las fuentes de error y producir simulaciones más realistas, <strong>160 investigadores de 60 universidades se han unido y han formado la Colaboración AGORA</strong>, que presenta ahora los resultados de su <strong>primer conjunto de simulaciones cosmológicas de la formación de una galaxia como la nuestra, la Vía Láctea, con el fin de avanzar hacia una teoría de la formación de las galaxias, ya que es crucial comparar los resultados y los códigos de diferentes simulaciones.</strong> &#8220;Ahora lo hemos conseguido reuniendo grupos de códigos que compiten entre sí, simulando galaxias, en una especie de super simulador&#8221;, afirma <strong>Santi Roca-Fábrega</strong>.</p>
<p>La simulación se basa en los mismos supuestos astrofísicos sobre radiación ultravioleta de fondo, enfriamiento del gas, calentamiento y formación estelar. Con la ayuda de los nuevos resultados, los <strong>investigadores pueden determinar que las galaxias de disco como la Vía Láctea podrían haber comenzado a formarse al principio de la historia del Universo, en total consonancia con las observaciones del telescopio James Webb</strong>.</p>
<p>También<strong> han descubierto que el número de galaxias satélite </strong>(galaxias que orbitan galaxias mayores)<strong> es coherente con las observaciones independientemente de la estrategia de simulación utilizada, lo que resuelve por completo un viejo problema denominado &#8220;problema de los satélites desaparecidos&#8221;, que consistía en la ausencia en las observaciones de la gran población de pequeñas galaxias satélite predicha por las simulaciones de materia oscura sola sin la inclusión de gas y estrellas</strong>. Además, el equipo de investigación ha revelado cómo <strong>la recuperación de las propiedades observadas del gas que rodea a las galaxias es la clave para obtener simulaciones realistas,</strong> en lugar de ajustar el número y la distribución de las estrellas, que era lo habitual hasta ahora.</p>
<p>Además, a raíz de estos artículos, se han abiertos nuevos caminos para entender mejor la formación de galaxias, en particular, el <strong>estudiante de doctorado de la UCM, Ramón Rodríguez Cardoso está analizando cómo las pequeñas galaxias son canibalizadas por las más grandes en un proceso que puede durar miles de millones de años. </strong>El trabajo se ha prolongado durante los últimos ocho años y ha supuesto la ejecución de cientos de simulaciones y el empleo de más de cien millones de horas en instalaciones de supercomputación, explica <strong>Santi Roca-Fábrega.</strong></p>
<p>Ahora el trabajo continúa hacia un mayor refinamiento de las simulaciones en torno a la formación de galaxias. Con cada avance tecnológico, <strong>Santi Roca-Fábrega</strong> y sus colegas esperan añadir nuevas piezas al rompecabezas de la vertiginosa cuestión del nacimiento y evolución del universo y las galaxias.</p>
<p>&#8220;La colaboración nos ha ayudado a mejorar los códigos numéricos encontrando y corrigiendo errores y comprendiendo mejor cómo los parámetros de cada código controlan los procesos astrofísicos, incluida la formación estelar. Este es el punto de partida para realizar simulaciones más fiables de la formación de galaxias, lo que a su vez nos ayudará a comprender mejor nuestra galaxia natal, la Vía Láctea&#8221;, afirma Santi Roca-Fábrega.</p>
<p>&nbsp;</p>
<p>El estudio se ha publicado en <em>The Astrophysical Journal</em>, con copias de libre acceso de los artículos en ArXiv:</p>

			<p><strong>This invited talk was the one that opened the congress, that was held at the Universidad Galileo in Guatemala City.</strong></p>
<p>Jesús Gallego reviewed our conception of the cosmos, since the beginning of humanity, the firmament has always attracted us as something distant and unreachable. From the sphere of fixed stars in the book &#8220;Del saber de la Astronomía&#8221; by Alfonso X, &#8220;the Wise&#8221;, to the large astronomical telescopes of today, the history of astronomy is based on the constant effort to know the nature of the increasingly remote universe that our instruments reveal to us. Jesús concluded by explaining what is currently known about the most remote universe.</p>

			<p>Included in his many accomplishments, Jaime is a driving force of light pollution research in Europe with a clear focus on the promotion of dark skies and the use of community science (such as STARS4ALL and ACTION project) to develop activities around dark skies. He is a professional astronomer and astrophysics professor at the Department of Astrophysics and Atmospheric Science at Universidad Complutense de Madrid (UCM). Together with colleagues at UCM, Jaime coordinated the actions towards the creation of the UCM Observatory. Its main research activities are now related to the astronomical quality of the night sky. Additionally, he leads a group working on this topic at UCM, and he is the coordinator of the Spanish Light Pollution Research Network (REECL). Also, Jamie led the team that designed the TESS-W (Telescope Encoder and Sky Sensor) to monitor sky brightness. The goal was to create a device that may be replicated at low cost by others with science quality measurements. At the same time, Jamie kept in mind the need for the light pollution community to have open hardware designs (the TESS photometer design is available under a Creative Commons license) and, more importantly, to have a large set of open data available for everybody with measurements all around the world.</p>
<p>Since its foundation in 2021, Jamie has also been the coordinator of the <a href="https://guaix.fis.ucm.es/lica">Laboratory for Scientific Advanced Instrumentation</a> (Laboratorio de Instrumentación Científica Avanzada, LICA). This laboratory belongs to the UCM research laboratories network and is being used by many researchers in the light pollution field to characterize their instruments. For example, nearly every participant of the international LoNNe Intercomparison Campaign provided some instrument or filter to be characterized in the LICA lab.</p>
<p>Jaime is often referred to as a team builder. He frequently collaborates with students and colleagues on projects such as the calibration of the International Space Station (ISS) images and the ‘Cities at Night’ Project in partnership with Alejandro Sánchez de Miguel, design of COELOFO (a multi-channel photometer), and the promotion of a multitude of community science programs among many other projects. Additionally, thus far in his career, Jamie has published numerous papers on light pollution.</p>

<p><strong>Since the end of 2019, the Professor of Paleontology, Juan Luis Arsuaga, and the Professor of Astrophysics, Jesús Gallego, have been involved in a series of conferences (many of them online during the pandemic) in which they demand the need for a multidisciplinary discipline that investigates the origins of the cosmos, of life and of our species. Their intense activity has led them to organize the course &#8220;Initium, the science of origins&#8221; in this edition of the UCM Summer Courses.</strong></p>

			<p><span lang="EN-GB" xml:lang="EN-GB">Only a small fraction of the galaxies emits gamma rays, which is the most extreme form of light. Astronomers believe that these highly energetic photons originate from the vicinity of a supermassive black hole residing at the centers of these galaxies. When this happens, they are known as <em>active galaxies</em>. The black hole swallows matter from its surroundings and emits jets or, in other words, collimated streams of matter and radiation. Few of these active galaxies (less than 1%) have their jets pointing by chance toward Earth. Scientists call them <em>blazars</em> and are one of the most powerful sources of radiation in the universe.</span></p>
<p><span lang="EN-GB" xml:lang="EN-GB">Blazars come in two flavors: BL Lacertae (BL Lac) and flat-spectrum radio-quasars (FSRQs). Our current understanding about these mysterious astronomical objects is that FSRQs are relatively young active galaxies, rich in dust and gas that surround the central black hole. As time passes, the amount of matter available to feed the black hole is consumed and the FSRQ evolves to become a BL Lac object. &#8220;In other words, BL Lacs may represent the elderly and evolved phase of a blazar&#8217;s life, while FSRQs resemble an adult,&#8221; explains <strong>Vaidehi Paliya</strong>, a DESY researcher who participated in this program.</span></p>
<p>“Since the speed of light is limited, the farther we look, the earlier in the age of the Universe we investigate,” says <strong>Alberto Domínguez</strong> of the Institute of Physics of Particles and the Cosmos (IPARCOS) at UCM and co-author of the study. Astronomers believe that the current age of the Universe is around 13.8 billion years. The most distant FSRQ was identified at a distance when the age of the universe was merely 1 billion years. For a comparison, the farthest BL Lac that is known was found when the age of the Universe was around 2.5 billion years. Therefore, the hypothesis of the evolution from FSRQ to BL Lacs appears to be valid.</p>

			<p>Now, the team of international scientists has discovered a new BL Lac object, named 4FGL J1219.0+3653, much farther away than the previous record holder. &#8220;We have discovered a BL Lac existing even 800 million years earlier, this is when the Universe was less than 2 billion years old,&#8221; states <strong>Cristina Cabello</strong>, a graduate student at IPARCOS-UCM. &#8220;This finding challenges the current scenario that BL Lacs are actually an evolved phase of FSRQ,&#8221; adds <strong>Nicolás Cardiel</strong>, a professor at IPARCOS-UCM. <strong>Jesús Gallego</strong>, also a professor at the same institution and a co-author of the study concludes: “This discovery has challenged our knowledge of the cosmic evolution of blazars and active galaxies in general.”</p>

<p style="text-align: left;">These days has finished the installation of a brand-new ISO7 clean room at our <a href="https://guaix.ucm.es/instrumentation#lica">LICA laboratory</a>. The new facility will allow the manipulation and characterization of high-tech devices that need such level of cleaning. Specifically, LICA is now fully qualified for the work with scientific-level detectors, optical components, and complex instrumental setups.</p>
<p style="text-align: left;">The LICA clean room has a total area of 30 square meters. Some of the first tasks to be performed at this new facility are the assembly of four ESO Continuous Flow Cryostats and the first stage of the laboratory integration of the SCORPIO instrument for Gemini telescopes (leader center: South West Research Institute, San Antonio, Texas), both in collaboration with private company FRACTAL S.L.N.E.</p>

			<p>This didactic unit on the <a href="https://citiesatnight.org">Cities at Night</a> citizen science project aims to generate social awareness about the problem of light pollution, bring scientific research closer to schools and of course encourage young people to participate in the project.</p>
<p>This teaching material will allow you to work in the classroom with high school students with ages around 14 years old. It is divided into two parts, the first one is intended for the educator so we present this citizen science project and the didactical unit methodology.</p>
<p>The second one is intended for young students and includes general content about light pollution, its negative effects and basic recommendations to improve lighting inside and outside home.</p>
<p>It also reviews the basic lines of the Cities at Night project and highlights the potential of satellite images to locate light pollution sources and monitor their evolution over time.</p>
<p>The text includes activities to reinforce the concepts, with their solutions to be checked by teachers, as well as some links with more information.</p>
