Lensing-Reconstructed Dark Matter-Intracluster Medium Coherence as a Probe of Cluster Dynamical State: Application to HSTFF, RELICS, and CLASH Clusters
Giulia Cerini, Sayan Saha, Jacqueline McCleary +13
We present the first application of Fourier-space coherence analysis between the lensing-reconstructed projected mass distribution and the X-ray-emitting intracluster medium to a s…
Understanding the regulation of star formation within TNG100 galaxies on kpc-scales using machine learning I: Global versus local
Bryanne McDonough, Sathvika S. Iyengar, Ansa Brew-Smith +2
We apply Random Forest and XGBoost machine learning algorithms to determine which galaxy properties most effectively predict star formation and quenching in simulated galaxies. Usi…
Void Galaxies and AGN Activity in ZOBOV-identified TNG300 Voids Out to z=3.0
Olivia Curtis, Bryanne McDonough, Tereasa Brainerd
We study void galaxies in the TNG300 simulation between redshifts and . Cosmic void catalogs were constructed using a watershed-based void-finding algorithm, and we defi…
Measuring Scaling Relationships: Fitting Technique Matters
Bryanne McDonough, Olivia Curtis, Tereasa Brainerd
Scaling relationships, both integrated and spatially resolved, arise due to the physical processes that govern galaxy evolution and are frequently measured in both observed and sim…
Density Profiles of TNG300 Voids across Cosmic Time
Olivia Curtis, Bryanne McDonough, Tereasa Brainerd
We present radial density profiles, as traced by luminous galaxies and dark matter particles, for voids in eleven snapshots of the \texttt{TNG300} simulation. The snapshots span 11…
Magnetic Fields of Satellite Galaxies Stronger Than Comparable Centrals in TNG100
Bryanne McDonough, Alexander Poulin
Magnetic fields exist in and around galaxies, but the properties of these fields have not been fully explored due to the challenges inherent in observing and modeling them. In this…
