The Three Hundred: Cluster Dynamical States and Relaxation Time Scale
Bowei Zhang, Weiguang Cui, Romeel Dave +1
Using the galaxy clusters from The Three Hundred Project, we define a new parameter: to describe the dynamical state of clusters, which assumes a double-Gaussian distribut…
How baryons affect halos and large-scale structure: a unified picture from the Simba simulation
Daniele Sorini, Romeel Dave, Weiguang Cui +1
Using the state-of-the-art suite of hydrodynamic simulations Simba, as well as its dark-matter-only counterpart, we study the impact of the presence of baryons and of different ste…
Inferring halo masses with Graph Neural Networks
Pablo Villanueva-Domingo, Francisco Villaescusa-Navarro, Daniel Anglés-Alcázar +7
Understanding the halo-galaxy connection is fundamental in order to improve our knowledge on the nature and properties of dark matter. In this work we build a model that infers the…
Rapidly quenched galaxies in the Simba cosmological simulation and observations
Yirui Zheng, Romeel Dave, Vivienne Wild +1
A wide range of mechanisms have been put forward to explain the quenching of star formation in galaxies with cosmic time, however, the true balance of responsible mechanisms remain…
Detection of a Multiphase Intragroup Medium: Results from the COS-IGrM Survey
Tyler McCabe, Sanchayeeta Borthakur, Timothy Heckman +3
We present the results of the COS Intragroup Medium (COS-IGrM) Survey that used the Cosmic Origins Spectrograph on the Hubble Space Telescope to observe a sample of 18 UV bright qu…
The CAMELS Multifield Dataset: Learning the Universe's Fundamental Parameters with Artificial Intelligence
Francisco Villaescusa-Navarro, Shy Genel, Daniel Angles-Alcazar +25
We present the Cosmology and Astrophysics with MachinE Learning Simulations (CAMELS) Multifield Dataset, CMD, a collection of hundreds of thousands of 2D maps and 3D grids containi…
