Observational Signatures of AGN Feedback in the Morphology and the Ionization States of Milky Way-like Galaxies
Nadia Qutob, Razieh Emami, Kung-Yi Su +24
We make an in-depth analysis of different AGN jet models' signatures, inducing quiescence in galaxies with a halo mass of . Three jet models, including cosmic ray-…
CloudFlex: A Flexible Parametric Model for the Small-Scale Structure of the Circumgalactic Medium
Cameron B. Hummels, Kate H. R. Rubin, Evan E. Schneider +1
We present CloudFlex, a new open-source tool for predicting the absorption-line signatures of cool gas in galaxy halos with complex small-scale structure. Motivated by analyses of…
The Dispersion Measure Contributions of the Cosmic Web
Charles R. H. Walker, Laura G. Spitler, Yin-Zhe Ma +3
The large-scale distribution of baryons is sensitive to gravitational collapse, mergers, and galactic feedback. Known as the Cosmic Web, its large-scale structure (LSS) can be clas…
Synchrotron Signatures of Cosmic Ray Transport Physics in Galaxies
Sam B. Ponnada, Iryna S. Butsky, Raphael Skalidis +7
Cosmic rays (CRs) may drive outflows and alter the phase structure of the circumgalactic medium, with potentially important implications on galaxy formation. However, these effects…
Synchrotron Emission on FIRE: Equipartition Estimators of Magnetic Fields in Simulated Galaxies with Spectrally-Resolved Cosmic Rays
Sam B. Ponnada, Georgia V. Panopoulou, Iryna S. Butsky +7
Synchrotron emission is one of few observable tracers of galactic magnetic fields (\textbf{B}) and cosmic rays (CRs). Much of our understanding of \textbf{B} in galaxies comes from…
The Large Magellanic Cloud's Kiloparsec Bow Shock and its Impact on the Circumgalactic Medium
David J. Setton, Gurtina Besla, Ekta Patel +3
The interaction between the supersonic motion of the Large Magellanic Cloud (LMC) and the Circumgalactic Medium (CGM) is expected to result in a bow shock that leads the LMC's gase…
The Halo21 Absorption Modeling Challenge: Lessons From "Observing" Synthetic Circumgalactic Absorption Spectra
Zachary Hafen, Sameer, Cameron Hummels +7
In the Halo21 absorption modeling challenge we generated synthetic absorption spectra of the circumgalactic medium (CGM), and attempted to estimate the metallicity, temperature, an…
