A High-Mass Size Deficit for Void Galaxies in the Complete SDSS DR7
Olivia Curtis, Bryanne McDonough, Tereasa G. Brainerd
We characterize how environment shapes the sizes, luminosity functions, and mass functions of galaxies in large-scale underdensities by comparing the NSA catalog of the Sloan Digit…
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…
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…
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…
Intrinsic and Environmental Effects on the Distribution of Star Formation in TNG100 Galaxies
Bryanne McDonough, Olivia Curtis, Tereasa Brainerd
We present radial profiles of luminosity-weighted age, , and for various populations of high- and low- mass central and satellite galaxies in the TNG100 cosmologi…
Properties of Voids and Void Galaxies in the TNG300 Simulation
Olivia Curtis, Bryanne McDonough, Tereasa G. Brainerd
We investigate the properties of voids and void galaxies in the \texttt{TNG300} simulation. Using a luminous galaxy catalog and a spherical void finding algorithm, we identify 5,07…
Resolved star formation in TNG100 central and satellite galaxies
Bryanne McDonough, Olivia Curtis, Tereasa Brainerd
Recent cosmological hydrodynamical simulations have produced populations of numerical galaxies whose global star-forming properties are in good agreement with those of observed gal…
The Distribution of Satellite Galaxies in the TNG100 Simulation
Bryanne McDonough, Tereasa Brainerd
We investigate the spatial distribution of the satellites of isolated host galaxies in the TNG100 simulation. In agreement with a previous, similar analysis of the Illustris-1 simu…
Modeling the Infrared Reverberation Response of the Circumnuclear Dusty Torus in AGNs: An Investigation of Torus Response Functions
Triana Almeyda, Andrew Robinson, Michael Richmond +2
The size and structure of the dusty circumnuclear torus in active galactic nuclei (AGN) can be investigated by analyzing the temporal response of the torus's infrared (IR) dust emi…
