Estimating Dark Matter Halo Masses in Simulated Galaxy Clusters with Graph Neural Networks
Nikhil Garuda, John F. Wu, Dylan Nelson +1
Galaxies grow and evolve in dark matter halos. Because dark matter is not visible, galaxies' halo masses () must be inferred indirectly. We present a graph neur…
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…
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…
The cooler past of the intracluster medium in TNG-Cluster
Eric Rohr, Annalisa Pillepich, Dylan Nelson +3
The intracluster medium (ICM) today is comprised largely of hot gas with clouds of cooler gas of unknown origin and lifespan. We analyze the evolution of cool gas (temperatures $\l…
MAGAZ3NE: Massive, Extremely Dusty Galaxies at Lead to Photometric Overestimation of Number Densities of the Most Massive Galaxies at
Ben Forrest, M. C. Cooper, Adam Muzzin +17
We present rest-frame optical spectra from Keck/MOSFIRE and Keck/NIRES of 16 candidate ultramassive galaxies targeted as part of the Massive Ancient Galaxies at Near-Infrared…
