3rd SCHOOL: Gravitational Waves in Astrophysics
January 19-23, 2026
Campus Casona, UNAB, Santiago
Scientific Organizing Committee
- Celeste Artale (Universidad Andrés Bello)
- Macarena Lagos (Universidad Andrés Bello)
- Franz Bauer (Universidad de Tarapacá)
- Alessandro Trani (Universidad de Concepción)
- Jorge Cuadra (Universidad Adolfo Ibáñez)
- Hanne Van Den Bosch (Universidad de Chile)
School Rationale
This school will introduce participants to recent developments in gravitational-wave and high-energy astrophysics. This is the third edition of “Gravitational Waves in Astrophysics schools” in Chile.
In 2026, the program will include three main lectures by international experts:
- Binary Black Holes in Active Galactic Nuclei (AGNs) by Zoltan Haiman: The influence of gas-rich environments on the formation and evolution of binary black holes.
- Quasi-Periodic Eruptions (QPEs) and Tidal Disruption Events (TDEs) by Andreja Gomboc: Transient phenomena that shed light on accretion physics and stellar interactions with massive black holes.
- Extreme Mass Ratio Inspirals (EMRIs) by Christian Chapman-Bird: Compact objects orbiting and merging with supermassive black holes, key sources for future space-based detectors.
Through these topics, the school aims to provide a broad overview of compact object astrophysics and its connections to multi-messenger observations. Note that all lectures will be given in English.
Invited Lecturers

Andreja Gomboc (University of Nova Gorica, Slovenia)
Andreja Gomboc is Professor of Astronomy at the University of Nova Gorica, where she is leading Slovenian participation in the Vera Rubin Observatory’s Legacy Survey of Space and Time. Following her PhD in physics at the University of Ljubljana, she was a Marie Skłodowska Curie fellow at the Liverpool John Moores University, UK, and, later,a Fulbright Scholar at the University of Washington, USA. Her main field of research is astrophysical transients, in particular tidal disruptions of stars in the vicinity of massive black holes and gamma-ray bursts.

Zoltan Haiman (Institute of Science and Technology, Austria)
Professor Zoltan Haiman received a B.S. degree in Physics from MIT and attended graduate school in Cambridge, UK, and at Harvard University, where he earned a Ph.D. in Astronomy in 1998. He was a Hubble Fellow at Princeton University and a postdoc in the Theoretical Astrophysics group at Fermilab, before joining the faculty at Columbia University. Since 2025, he has been on leave from Columbia and holds a group leader position at the Institute of Science and Technology Austria (ISTA). Professor Haiman’s research has explored broad topics in theoretical astrophysics and cosmology, including the formation of the first stars, the emergence of massive black holes, the nature of dark energy and dark matter, as well as astrophysical sources of gravitational waves. He was chosen as one of Popular Science Magazine’s Brilliant 10 young scientists in 2002 and received the New York Academy of Sciences Blavatnik Award in 2010, as well as a Simons Fellowship in Theoretical Physics in 2016. Since 2025, he has been serving as one of the 20 members of the LISA Science Team, appointed by the European Space Agency.

Christian Chapman-Bird (University of Birmingham , UK)
Christian Chapman-Bird is a postdoctoral research fellow at the University of Birmingham’s Institute for Gravitational-Wave Astronomy, which he joined after completing his PhD at the University of Glasgow in 2024. His work contributes to the the development of waveform modelling and data-analysis techniques for the Laser Interferometer Space Antenna (LISA), a European Space Agency flagship mission set for launch in a decade’s time that will observe millihertz gravitational waves from across the Universe. His research has particular focus on the modelling of asymmetric-mass binary systems, such as extreme-mass-ratio inspirals, which pose a significant challenge in both their modelling and subsequent analysis in LISA data.
Programme
The program will include a poster session, providing students with the opportunity to present and discuss their research results with peers and lecturers. There will also be a public colloquium (in Spanish) for general audience.

This is a tentative schedule, subject to changes.
Public Colloquium
Title: TBD
Date: Tuesday 20th, January 2026, at 5pm in Auditorio Aznar, Campus Casona, UNAB.

Celeste Artale (Universidad Andrés Bello)
Assistant professor at the Institute of Astrophysics at Universidad Andrés Bello, with a PhD from the National University of Buenos Aires. She is part of the Einstein Telescope collaboration and her research interests include simulations of formation and evolution of binary black holes and neutron stars.
