Galaxy pairs in the Sloan Digital Sky Survey - XII: The fuelling mechanism of low excitation radio-loud AGN
Sara L. Ellison, David R. Patton, Ryan C. Hickox
We investigate whether the fuelling of low excitation radio galaxies (LERGs) is linked to major galaxy interactions. Our study utilizes a sample of 10,800 spectroscopic galaxy pair…
Star Formation and Relaxation in 379 Nearby Galaxy Clusters
Seth A. Cohen, Ryan C. Hickox, Gary A. Wegner
We investigate the relationship between star formation (SF) and level of relaxation in a sample of 379 galaxy clusters at z < 0.2. We use data from the Sloan Digital Sky Survey to…
Variable Hard X-ray Emission from the Candidate Accreting Black Hole in Dwarf Galaxy Henize 2-10
Thomas J. Whalen, Ryan C. Hickox, Amy E. Reines +5
We present an analysis of the X-ray spectrum and long-term variability of the nearby dwarf starburst galaxy Henize 2-10. Recent observations suggest that this galaxy hosts an activ…
A Connection between Obscuration and Star Formation in Luminous Quasars
Chien-Ting J. Chen, Ryan C. Hickox, Stacey Alberts +15
We present a measurement of the star formation properties of a uniform sample of mid-IR selected, unobscured and obscured quasars (QSO1s and QSO2s) in the Boötes survey region. We…
