An Investigation of 5-year Simultaneous X-ray and Radio Light Curves of the Dwarf Seyfert Galaxy UGC 6728

Krista Lynne Smith, Macon Magno, Michael Koss

We present serendipitous simultaneous radio and X-ray light curves of the dwarf Seyfert galaxy UGC 6728 spanning 5 years. The X-ray light curve exhibits a flaring period, followed…

BASS LII: The prevalence of double-peaked broad lines at low accretion rates among hard X-ray selected AGN

Charlotte Ward, Michael J. Koss, Michael Eracleous +18

A fraction of active galactic nuclei (AGN) have double-peaked H, H and Mg II broad lines attributed to emission from rotating gas in the accretion disk. Using optical spect…
