Agujeros negros con rotación y carga eléctrica en cinco dimensiones– Dr. Marcos Arcodía *
Instituto de Astronomía y Física del Espacio (CONICET-UBA) y Departamento de Física, FCEN, UBA
Resumen: Ante la ausencia de un análogo en dimensiones superiores del agujero negro de Kerr-Newman, la teoría de Einstein-Maxwell en cinco dimensiones, complementada con un término de Chern-Simons, se ha consolidado como un marco natural para el estudio de soluciones cargadas y estacionarias. Un ejemplo destacado es la solución de Chong-Cvetič-Lü-Pope (CCLP), que describe un agujero negro no extremal con carga eléctrica y dos momentos angulares independientes. En este trabajo reconsideramos una familia más amplia de soluciones de agujeros negros en cinco dimensiones de las ecuaciones de campo de Einstein-Maxwell-Chern-Simons (EMCS), que contiene a las soluciones de CCLP y Kerr-NUT-Anti-de Sitter como casos particulares. Mostramos que cuando los parámetros están en cierto dominio, estas métricas toman la forma de CCLP mediante una transformación de coordenadas adecuada y una redefinición de los parámetros.

- XIX IAG/USP Advanced School of Astrophysics
Radio Astronomy: Science and Instrumentation with the Next-Generation Telescopes
The XIX Advanced School of Astrophysics (EAA), organized by the Department of Astronomy at IAG/USP, will be held from September 1–5, 2025, at Hotel Cia do Mar in Bertioga, São Paulo, approximately 100 km from the Guarulhos International Airport (GRU).
This year’s edition will focus on radio astronomy, with a special emphasis on interferometry and VLBI. We are living a golden era for the field: facilities like ALMA and the Event Horizon Telescope (EHT) have transformed our understanding of star formation, galaxy evolution, and supermassive black holes. The next generation of observatories — including the Square Kilometer Array (SKA) and ngVLA — will further revolutionize the field thanks to their unparalleled sensitivity and resolution.
This school comes at a pivotal time for radio astronomy in Brazil and Latin America, with the LLAMA telescope — co-developed by Brazil and Argentina — nearing completion in the Andes. The event will provide a unique opportunity to foster collaborations and advance plans for LLAMA’s participation in global VLBI networks such as EHT and ALMA.
The program includes five in-depth courses covering key astrophysical processes, radio observation techniques, and data analysis:
* Alex Kraus (MPIfR, Germany)
* Maria Teresa Beltrán (INAF, Italy)
* Laurent Loinard (UNAM, Mexico)
* Raffaella Morganti (U. Groningen, Netherlands)
* Thomas Oosterloo (U. Groningen, Netherlands)
Complementary scientific seminars will be offered by:
Zulema Abraham, Phillip Galli, Ciriaco Goddi, Jacques Lépine, Rodrigo Nemmen, Reinaldo Santos-Lima (IAG/USP), C. Guillermo Giménez de Castro (CRAAM & CONICET/UBA), and Thomas Oosterloo.
The school is open to students and researchers seeking to deepen their knowledge of radio astronomy.

- First announcement of the JCMT Users Meeting 2025 –
Dear Colleagues,
We are pleased to announce that the JCMT Users meeting will be held from July 1st to July 4th, 2025, in Chiang Mai, Thailand (https://www.eaobservatory.org/jcmt/science/users-meeting-2025/).
The meeting will consist of both talks (invited and contribution) and posters on the current progress and updates on JCMT sciences and instrumentation. We also plan to arrange hands-on tutorial sessions and lectures for JCMT observations and data reduction, which would help beginners become more familiar with JCMT.
As many of you may know, the partnership of the East Asian Observatory and JCMT has been changed, which may require reorganizing the JCMT user community, but at the same time allows the community to start new collaborations using JCMT. The users meeting would provide an excellent occasion for the community to have such discussions. We will make rooms available for teams that are carrying out current JCMT Large Programmes and for those who wish to discuss future collaborations.
More details will be circulated shortly, and in the meantime, please mark your calendar. If you have any questions about the meeting, please send emails to jcmt_um_2025_@_eaobservatory.org (replace _@_ with @).
Cheers,
Nagayoshi Ohashi on behalf of the SOC
- AstroRob2025 in Almería (6-10 Oct): First Announcement
Following the success of the previous workshops held in 2009, 2011, 2013, 2015, 2017, 2019, and 2023, we are delighted to announce the 8th Workshop on Robotic Autonomous Observatories (AstroRob2025). The workshop will take place in El Toyo (Almeria), Spain, from October 6 to 10, 2025.
Sixteen years after the inaugural workshop in Malaga, robotic and autonomous astronomical observatories have achieved remarkable advancements. The global number of automated facilities has grown substantially, along with their capabilities in robotization, autonomy, and networking. These developments, driven by the search for electromagnetic counterparts to gravitational waves (such as the groundbreaking detection in 2017), have profoundly influenced diverse areas of astrophysics and beyond, including:
Fireball detection
Minor planet studies
Exoplanet searches
Monitoring variable stars in the Galaxy
Studying active galactic nuclei
Supernova detection and monitoring
Rapid follow-up of high-energy transients like gamma-ray bursts
Electromagnetic counterparts to neutrino and gravitational waves
The workshop will also highlight the increasing importance of space debris surveillance and tracking, the observation of Near-Earth Objects, the role of robotic observatories in public outreach and education, and their contributions to open science. The Scientific Organizing Committee aims to deliver a dynamic program
addressing scientific, technical, educational, and outreach themes.
We encourage researchers, engineers, educators, and enthusiasts working in these fields to join us at AstroRob2025. The success of this workshop series has been largely due to the active participation, insightful presentations, and engaging discussions contributed by its attendees. Your involvement is key to making the forthcoming workshop as fruitful and inspiring as previous editions.
1) VENUE AND LOGISTICS
The workshop will be held at the Hotel Barceló Cabo de Gata, located on the beachfront, 10 km from Cabo de Gata Natural Park and 4 km from Almería Airport (which is also a 2-hour drive from Málaga International Airport). Families are warmly welcome, with special discounts available for attendees. Early autumn offers pleasant temperatures, and swimming in the Mediterranean sea is still possible at this time of year. The workshop is hosted by the Instituto de Astrofisica de Andalucia (IAA-CSIC) under the auspices of the Spanish Research Council (CSIC), the University of Almeria and the Calar Alto Astronomical Observatory,
the largest in continental Europe. An excursion to the observatory is planned as part of the program.
