Cool Embeddings: Predicting Galaxy Cluster Cooling Times in IllustrisTNG and TNG-Cluster with AstroCLIP
Rawan Karam, Carter Lee Rhea, Julie Hlavacek-Larrondo +4
Foundation models trained on optical astronomical data have not previously been applied to X-ray cluster thermodynamics. We show that embeddings from AstroCLIP, a contrastive visio…
Mapping Gas Accretion and Stellar Kinematics to Sub-kiloparsec Scales in NGC 4696 with JWST/NIRSpec
Mathieu Marquis, Julie Hlavacek-Larrondo, Olivia Pereira +35
We present JWST/NIRSpec IFU spectroscopy of the central pc () of NGC 4696, the BCG in the Centaurus cluster. Leveraging the (…
JWST reveals how black holes are fed: kiloparsec-scale multiphase filaments feed sub-kiloparsec circumnuclear disks
Julie Hlavacek-Larrondo, Hyunseop Choi, Minghao Guo +35
The Centaurus cluster is one of the most important archetypes of radio-mode AGN feedback, with its central galaxy, NGC 4696, launching powerful jets that inflate X-ray cavities and…
Bulk vs. turbulent motions at the centres of galaxy clusters: AGN-driven turbulence according to TNG-Cluster
Bipradeep Saha, Annalisa Pillepich, Joey Braspenning +3
The highly dynamic intracluster medium (ICM) influences cluster thermodynamic evolution and probes key physical processes. Quantifying the non-thermal motions is therefore essentia…
X-ray shocks in the cool cores of galaxy clusters: insights from TNG-Cluster
Marine Prunier, Francesco Ubertosi, Julie Hlavacek-Larrondo +1
Shock fronts driven by active galactic nuclei in galaxy cluster cores represent a promising mechanism to heat the intracluster gas by converting kinetic energy into thermal energy…
Magnetic fields in the intracluster medium with TNG-Cluster: properties, morphology, and tangential anisotropy
Katrin Lehle, Mateusz Ruszkowski, Dylan Nelson +2
We characterize the magnetic field properties of 352 massive galaxy clusters from the TNG-Cluster magnetohydrodynamical cosmological simulation with a focus on central magnetic fie…
X-ray cavities in TNG-Cluster: a direct comparison to observations
Marine Prunier, Annalisa Pillepich, Julie Hlavacek-Larrondo +1
The TNG-Cluster magnetohydrodynamic cosmological simulations, produce a diverse population of X-ray cavities in the intracluster medium (ICM) of simulated galaxy clusters. These ar…
HST Observations within the Sphere of Influence of the Powerful Supermassive Black Hole in PKS0745-191
Julie Hlavacek-Larrondo, Hyunseop Choi, Minghao Guo +18
We present Space Telescope Imaging Spectrograph observations from the Hubble Space Telescope of the supermassive black hole (SMBH) at the center of PKS0745-191, a brightest cluster…
X-ray cavities in TNG-Cluster: AGN phenomena in the full cosmological context
Marine Prunier, Julie Hlavacek-Larrondo, Annalisa Pillepich +2
Active galactic nuclei (AGN) feedback from supermassive black holes (SMBHs) at the centers of galaxy clusters plays a key role in regulating star formation and shaping the intraclu…
Deconvolving X-ray Galaxy Cluster Spectra Using a Recurrent Inference Machine
Carter Rhea, Julie Hlavacek-Larrondo, Alexandre Adam +4
Recent advances in machine learning algorithms have unlocked new insights in observational astronomy by allowing astronomers to probe new frontiers. In this article, we present a m…
