The effects of bar strength and kinematics on galaxy evolution II: The global and local impacts of slow-strong bars
Petra Mengistu, Karen L. Masters, Tobias Geron +3
There is now clear evidence, from a variety of studies, that galactic bars contribute to and/or accelerate processes which quench galaxies. However, bars have a variety of strength…
AT 2024ahzi: A Type IIP Supernova Discovered by the LSST Commissioning Camera
Kaylee de Soto, V. Ashley Villar, Jared A. Goldberg +25
As part of its commissioning, the Vera C. Rubin Observatory observed several fields repeatedly for a month with ComCam, an instrument that uses the same hardware as the LSST camera…
Strong Bars, Strong Inflow: The Effect of Bar Strength on Gas Inflow
Maelle Magnan, Tobias Geron, Izzy L. Garland +5
Stellar bars are elongated structures in disk galaxies that can torque and funnel gas inward, influencing galaxy evolution. While strong bars are known to induce rapid inflow, the…
Timescales for the Effects of Interactions on Galaxy Properties and SMBH Growth
D. O'Ryan, B. D. Simmons, A. L. Faisst +15
Galaxy interaction and merging have clear effects on the systems involved. We find an increase in the star formation rate (SFR), potential ignition of active galactic nuclei (AGN)…
Galaxy Zoo JWST: Up to 75% of discs are featureless at
R. J. Smethurst, B. D. Simmons, T. Géron +21
We have not yet observed the epoch at which disc galaxies emerge in the Universe. While high- measurements of large-scale features such as bars and spiral arms trace the evoluti…
