ERGO-ML: A continuous organization of the X-ray galaxy cluster population in TNG-Cluster with contrastive learning
Urmila Chadayammuri, Lukas Eisert, Annalisa Pillepich +3
The physical properties of the intracluster medium (ICM) reflect signatures of the underlying gravitational potential, mergers and strong interactions with other halos and satellit…
What is the Role of Large Language Models in the Evolution of Astronomy Research?
Morgan Fouesneau, Ivelina G. Momcheva, Urmila Chadayammuri +10
ChatGPT and other state-of-the-art large language models (LLMs) are rapidly transforming multiple fields, offering powerful tools for a wide range of applications. These models, co…
Closing Pandora's Box -- The deepest X-ray observations of Abell 2744 and a multi-wavelength merger picture
Urmila Chadayammuri, Ákos Bogdán, Gerrit Schellenberger +1
Abell 2744, also known as Pandora's Cluster, is a complex merging galaxy cluster. While a major merger is clear along the north-south axis, the dynamical state of the northwest sub…
X-Ray Bright Active Galactic Nuclei in Local Dwarf Galaxies: Insights from eROSITA
Andrea Sacchi, Akos Bogdan, Urmila Chadayammuri +1
Although supermassive black holes (SMBHs) reside in the heart of virtually every massive galaxy, it remains debated whether dwarf galaxies commonly host SMBHs. Because low-mass gal…
Improved Constraints on Mergers with SZ, Hydrodynamical simulations, Optical, and X-ray (ICM-SHOX). Paper II: Galaxy cluster sample overview
Emily M. Silich, Elena Bellomi, Jack Sayers +12
Galaxy cluster mergers are representative of a wide range of physics, making them an excellent probe of the properties of dark matter and the ionized plasma of the intracluster med…
A candidate supermassive black hole in a gravitationally-lensed galaxy at
Orsolya E. Kovacs, Akos Bogdan, Priyamvada Natarajan +8
While supermassive black holes (BHs) are widely observed in the nearby and distant universe, their origin remains debated with two viable formation scenarios with light and heavy s…
Decoding the Early Universe: Exploring a Merger Scenario for the High-Redshift Cluster JKCS041 using Numerical Models
Sharon Felix, Antareep Gogoi, Kaitlyn Shavelle +6
JKCS041 () is one of the most distant galaxy cluster systems known, seen when the Universe was less than 4 billion years old. Recent Sunyaev-Zeldovich (SZ) observations show…
