The molecular gas content throughout the low-z merger sequence
Mark T. Sargent, S. L. Ellison, J. T. Mendel +5
Exploiting IRAM 30m CO spectroscopy, we find that SDSS post-merger galaxies display gas fractions and depletion times enhanced by 25-50%, a mildly higher CO excitation, and standar…

Galaxy evolution in the post-merger regime. III -- The triggering of active galactic nuclei peaks immediately after coalescence
Sara L. Ellison, Leonardo Ferreira, Robert Bickley +6
Galaxy mergers have been shown to trigger AGN in the nearby universe, but the timescale over which this process happens remains unconstrained. The Multi-Model Merger Identifier (MU…

The reliability of gas-phase metallicities immediately adjacent to non-star-forming spaxels in MaNGA
Jillian M. Scudder, Aidan Khelil, Jonah Z. Ordower
In this work, we use gas phase metallicities calculated from the Sloan Digital Sky Survey (SDSS) Mapping Nearby Galaxies at Apache Point (MaNGA) Data Release 17 (DR17) to assess th…
