A New Physical Picture for AGNs Lacking Optical Emission Lines
Christopher J. Agostino, Samir Salim, Sara L. Ellison +2
In this work, we use ~500 low-redshift (z ~ 0.1) X-ray AGNs observed by XMM-Newton and SDSS to investigate the prevalence and nature of AGNs that apparently lack optical emission l…
Galaxy mergers can rapidly shut down star formation
Sara L. Ellison, Scott Wilkinson, Joanna Woo +6
Galaxy mergers trigger both star formation and accretion onto the central supermassive black hole. As a result of subsequent energetic feedback processes, it has long been proposed…
The merger fraction of post-starburst galaxies in UNIONS
Scott Wilkinson, Sara L. Ellison, Connor Bottrell +4
Post-starburst (PSB) galaxies are defined as having experienced a recent burst of star formation, followed by a prompt truncation in further activity. Identifying the mechanism(s)…
Star formation characteristics of CNN-identified post-mergers in the Ultraviolet Near Infrared Optical Northern Survey (UNIONS)
Robert W. Bickley, Sara L. Ellison, David R. Patton +3
The importance of the post-merger epoch in galaxy evolution has been well-documented, but post-mergers are notoriously difficult to identify. While the features induced by mergers…
