Polarimetric imaging of M87* with the EHT enabled significantly stronger inferences on the black hole and accretion parameters than total intensity data alone. Geometric modeling was a central tool for studying the structure of M87* and Sgr A* in total intensity. In the first part of the talk\, I will show the results of fitting a new polarimetric “m-ring” geometric model to EHT observations of M87*. Our geometric modeling results are generally consistent with imaging methods\, but they also enable studies of the black hole when imaging methods struggle\, such as nights with sparse coverage or weak signals. \nIn the second part of the talk\, I will focus on plans and science goals for future instruments. The Next-Generation EHT (ngEHT) will be a transformative enhancement of the EHT\, with array expansions and improvements allowing for\, e.g.\, high dynamic range imaging of AGN jets\, and for real-time movie reconstructions of variable sources like Sgr A*. With the ngEHT Analysis Challenges\, we explore the science capabilities of the ngEHT\, and develop new analysis algorithms capable of analyzing the large and complex ngEHT datasets. Finally\, I will give a brief overview of several proposals to image black holes using space-based telescopes\, which achieve order-of-magnitude angular resolution improvements compared to what is attainable from the ground and allow for high-precision tests of general relativity. \nFecha: 09/11/2023 – 12:30Conferenciante: Dr. Freek RoelofsFiliación: Center for Astrophysics\, Harvard & Smithsonian\, USA. \n  URL:https://www.iaa.csic.es/evento/studying-magnetic-fields-dynamics-and-fundamental-physics-near-a-black-hole-with-current-and-future-mm-vlbi-instruments/ LOCATION:IAA – CSIC\, Glorieta de la Astronomía\, Granada\, España CATEGORIES:Seminarios ATTACH;FMTTYPE=image/png:https://www.iaa.csic.es/wp-content/uploads/2023/11/seminarscover-e1752660087307.png END:VEVENT BEGIN:VEVENT DTSTART;TZID=Europe/Paris:20231114T080000 DTEND;TZID=Europe/Paris:20231115T190000 DTSTAMP:20260523T183554 CREATED:20231109T165952Z LAST-MODIFIED:20250912T080419Z UID:19840-1699948800-1700074800@www.iaa.csic.es SUMMARY:Meeting on Light Pollution: Challenges and Responses for Monitoring it DESCRIPTION:Light pollution has a direct impact on the environment\, on astronomical observations and on the starry sky as a heritage resource of humanity. Excessive light confuses the biological clocks of humans\, animals and plants with its spectral composition similar to daylight. As a result\, it makes it difficult to distinguish between day and night and between the seasons to which living organisms are physiologically attuned. Light pollution is therefore an environmental problem caused by the inappropriate use of artificial light (the pollutant) with a strong transboundary character because\, under the right conditions\, light can spread up to hundreds of kilometres away from its source. It can therefore affect habitats far away from the pollutant sources. \nFor this reason\, the Ministry of Science and Innovation of the Spanish government\, through the Instituto de Astrofísica de Andalucía of the Consejo Superior de Investigaciones Científicas\, is organising\, in collaboration with the Spanish Network of Studies on Light Pollution\, this international scientific meeting dedicated to addressing the pressing issues surrounding light pollution and its monitoring\, which is a matter of significant environmental and legal concern. This meeting is dedicated to addressing the pressing issues surrounding light pollution and its monitoring\, which is a matter of significant environmental and legal concern. \nThe program is structured into four insightful sessions: \nLegal and Environmental Justification for Monitoring Light Pollution: This session will delve into the legal frameworks and environmental imperatives driving the need for vigilant monitoring of light pollution. \nMeasurement of Light Pollution on Ground: Experts will share methodologies and latest technologies employed in measuring light pollution at the terrestrial level. \nSatellite Measurement of Light Pollution: This session will focus on the advancements in satellite technology aiding in the monitoring of light pollution from space. \nNeeds for Modelling Light Pollution: Discussions in this session will center around the requirements and strategies for accurate modelling of light pollution to aid in policy formulation and implementation. \n  \nNota de prensa \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n Advisory CommitteeAlejandro Sánchez (Head of AC)Salvador BaráJaime ZamoranoHelena VancovaFrank HolkerAndreas JechowKevin GastonManolis KogevinasKarolina Zielińska-DąbkowskaToñi VarelaFabio FalchiBenedikt HugginsYana YakushinaSusana MartinDavid GaladíPaco Colomer \n \n \n \n \n \n \n \n \n \n \n \n Local Organizing CommitteeAlicia Pelegrina (Head of LOC)Antxon AlberdiFrancisco Javier Moreno FuentesJose Manuel VílchezJose Luis OrtízSusana MartínMáximo BustamanteEmilio GarcíaCelia Navas \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n \n ORGANIZADO POR \n \n  \nLa Red Española de estudios sobra la contaminación lumínica y esta reunión están apoyados por la Ayuda RED2022-134733-T financiada por MICIU/AEI /10.13039/501100011033.

It determines the solution by finding similar 3-point asterisms (triangles) in both images and estimating the affine transformation between them. ASTROALIGN is particularly useful when there is no WCS information available or when the images to be aligned have been taken at different wavelengths and initial “by eye” alignment is very challenging. In this 1h workshop I will impart a brief introduction into the capabilities of ASTROALIGN and how to use it. \n  URL:https://www.iaa.csic.es/evento/pysnacks-5-astroalign/ LOCATION:On line CATEGORIES:SO Training ATTACH;FMTTYPE=image/png:https://www.iaa.csic.es/wp-content/uploads/2023/11/AstroAlign.png END:VEVENT BEGIN:VEVENT DTSTART;VALUE=DATE:20231116 DTEND;VALUE=DATE:20231118 DTSTAMP:20260523T183554 CREATED:20231109T182152Z LAST-MODIFIED:20250912T081122Z UID:19922-1700092800-1700265599@www.iaa.csic.es SUMMARY:Severo Ochoa Basics of Neural Networks 2023 DESCRIPTION:Deep learning (DL) is a family of techniques widely used in multiple fields with excellent results. Unfortunately\, due to its steep learning curve\, its use is not as extended as desirable. Several domain-specific libraries have been developed to facilitate the use of these DL models with modest success. For the widespread adoption of these techniques\, researchers should be able to design and use their own DL models. Image classification is one of the main problems in astrophysics. \nSOCRainer Schödel (Chair)\, IAA-CSIC\, SpainLaura Darriba\, IAA-CSIC\, SpainJavier Moldón\, IAA-CSIC\, Spain URL:https://www.iaa.csic.es/evento/severo-ochoa-basics-of-neural-networks-2023/ LOCATION:IAA – CSIC\, Glorieta de la Astronomía\, Granada\, España CATEGORIES:SO Training ATTACH;FMTTYPE=image/png:https://www.iaa.csic.es/wp-content/uploads/2023/11/neuralso.png END:VEVENT BEGIN:VEVENT DTSTART;TZID=Europe/Paris:20231116T123000 DTEND;TZID=Europe/Paris:20231116T133000 DTSTAMP:20260523T183554 CREATED:20231109T160244Z LAST-MODIFIED:20250912T071036Z UID:19786-1700137800-1700141400@www.iaa.csic.es SUMMARY:SO Colloquium: The evolution of the accretion process: investigating the protostellar phase to constraints planet formation DESCRIPTION:The accretion process is responsible for the mass building during the star formation phase\, but our knowledge of this phenomenon is still not totally understood. On one side\, the magnetospheric accretion scenario describes the accretion on pre-main sequence (Class II/III) low-mass stars. However\, most of the material is supposed to be accreted during the earliest stages\, i.e. the protostellar phase (Class 0/I)\, when the forming star and its disk are embedded into a dusty envelope. The presence of the envelope and short lifetimes make the observations of these sources and their analysis challenging\, preventing us from testing this and other scenarios during the early stages. On the other hand\, the Gaia data alert project is increasing the number of the so-called «eruptive sources» (FUor\, EXors..)\, which were thought to represent only an exception in the accretion paradigm\, suggesting their presence in the stellar mass building to be more important than we thought. In the last decade\, thanks to new instruments and analysis techniques\, we’re starting to unveil the secrets of accretion on low-mass protostars\, finding many similarities between these sources and the eruptive stars and finally being able to provide quantitative information about accretion parameters during the overall star formation evolution. In this talk I will present the most recent results about the stellar mass building during the early stages and how they impact the planet formation. \nFecha: 16/11/2023 – 12:30Conferenciante: Dr. Fiorellino\, EleonoraFiliación: Istituto di Astrofisica e Planetologia Spaziali di Roma and Istituto Nazionale di Astrofisica \n  URL:https://www.iaa.csic.es/evento/mosaic-the-high-multiplex-and-multi-ifu-spectrograph-for-the-elt/ LOCATION:IAA – CSIC\, Glorieta de la Astronomía\, Granada\, España CATEGORIES:SO Colloquium ATTACH;FMTTYPE=image/png:https://www.iaa.csic.es/wp-content/uploads/2025/07/SO-COLLOQUIUM.png END:VEVENT BEGIN:VEVENT DTSTART;TZID=Europe/Paris:20231123T123000 DTEND;TZID=Europe/Paris:20231123T133000 DTSTAMP:20260523T183554 CREATED:20231109T162054Z LAST-MODIFIED:20250911T092822Z UID:19809-1700742600-1700746200@www.iaa.csic.es SUMMARY:SO Colloquium: The transition between super-Earths and sub-Neptunes: Interior and atmosphere modelling of the low-mass planet population DESCRIPTION:Low-mass exoplanets are showing a diversity in their densities\, ranging from silicate-dominated super-Earths to volatile-rich sub-Neptunes. We have developed a coupled interior-atmosphere model that estimates the composition and interior structure of super-Earths and sub-Neptunes assuming water and CO2 atmospheres. The applications of the model include the homogenous analysis of a sample of multi-planetary systems\, as well as the assessment of the observability of emission spectra for rocky exoplanets with the James Webb Space Telescope. I will explain how their compositions connect to their possible formation site in the protoplanetary disk and their formation mechanisms\, including atmospheric escape\, and how we can break degeneracies with new atmospheric characterisation data. \nFecha: 23/11/2023 – 12:30Conferenciante: Dr. Lorena AcuñaFiliación: Max-Planck-Institute for astronomy\, Germany \n  URL:https://www.iaa.csic.es/evento/so-colloquium-the-transition-between-super-earths-and-sub-neptunes-interior-and-atmosphere-modelling-of-the-low-mass-planet-population/ LOCATION:IAA – CSIC\, Glorieta de la Astronomía\, Granada\, España CATEGORIES:Seminarios,SO Colloquium ATTACH;FMTTYPE=image/png:https://www.iaa.csic.es/wp-content/uploads/2025/07/SO-COLLOQUIUM.png END:VEVENT BEGIN:VEVENT DTSTART;VALUE=DATE:20231127 DTEND;VALUE=DATE:20231202 DTSTAMP:20260523T183554 CREATED:20231109T181908Z LAST-MODIFIED:20250912T081117Z UID:19914-1701043200-1701475199@www.iaa.csic.es SUMMARY:Severo Ochoa Advanced School on Star Formation DESCRIPTION:The IAA-CSIC Severo Ochoa Advanced School on Star Formation will be held in Granada\, from Monday\, November 27th\, to Friday\, December 1st\, 2023.

In order to analyze the star formation triggered in these systems\, we started a series of studies on ‘collisional’ galaxies with available integral field spectroscopy (IFS) observations. We use Very Large Telescope (VLT) Multi-Unit Spectroscopic Explorer (MUSE) observations to study the young star cluster complexes and H ii regions in the Antennae\, Cartwheel\, and the double-ring collisional galaxy AM 0644-741. MUSE datacubes offer the opportunity to address several problems that are particular to these galaxies\, such as studying the ionizing mechanisms and the chemical abundances in the star cluster complexes hosted in the H ii regions. IFS data also offers an opportunity to unveil the presence of populations of Wolf-Rayet stars and the sources of high ionization potential emission lines (e.g.\, He II 4686) in the nearby universe. We present our recent findings in this seminar. \nFecha: 30/11/2023 – 12:30Conferenciante: Dr. Victor Mauricio A.
