The Formation of Dwarf Galaxy Disks
Robel Geda, Akaxia Cruz, Anna C. Wright +5
Dwarf galaxies are dark matter-dominated systems that are sensitive to feedback and display a diversity of baryonic morphologies. This makes them excellent probes for understanding…
Unveiling the drivers of the Baryon Cycles with Interpretable Multi-step Machine Learning and Simulations
Mst Shamima Khanom, Benjamin W. Keller, Javier Ignacio Saavedra Moreno
We present a new approach for understanding how galaxies lose or retain baryons by utilizing a pipeline of two machine learning methods applied the IllustrisTNG100 simulation. We e…
Predictions for Detecting a Turndown in the Baryonic Tully Fisher Relation
Dilys Ruan, Alyson M. Brooks, Akaxia Cruz +5
The baryonic Tully Fisher relation (bTFR) provides an empirical connection between baryonic mass and dynamical mass (measured by the maximum rotation velocity) for galaxies. Due to…
GOALS-JWST: Gas Dynamics and Excitation in NGC7469 revealed by NIRSpec
Marina Bianchin, Vivian U, Yiqing Song +36
We present new JWST-NIRSpec IFS data for the luminous infrared galaxy NGC7469: a nearby (70.6Mpc) active galaxy with a Sy 1.5 nucleus that drives a highly ionized gas outflow and a…
A Catalog of 71 Coronal Line Galaxies in MaNGA: [NeV] is an Effective AGN Tracer
James Negus, Julia M. Comerford, Francisco Muller Sanchez +5
Despite the importance of AGN in galaxy evolution, accurate AGN identification is often challenging, as common AGN diagnostics can be confused by contributions from star formation…
UGC 4211: A Confirmed Dual Active Galactic Nucleus in the Local Universe at 230 pc Nuclear Separation
Michael J. Koss, Ezequiel Treister, Darshan Kakkad +23
We present multi-wavelength high-spatial resolution (~0.1'', 70 pc) observations of UGC 4211 at z=0.03474, a late-stage major galaxy merger at the closest nuclear separation yet fo…
