X-ray and radio observations of central black holes in nearby low-mass early-type galaxies: Preliminary evidence for low Eddington fractions
R. Urquhart, L. I. McDermott, J. Strader +5
We present new radio and X-ray observations of two nearby ( Mpc) low-mass early-type galaxies with dynamically-confirmed central black holes: NGC 5102 and NGC 205. NGC 5102 sh…

Quasi periodic whispers from a transient ULX in M\,101: signatures of a fast-spinning neutron star?
Ryan T. Urquhart, Roberto Soria, Rosanne Di Stefano +7
We have studied the unusual time variability of an ultraluminous X-ray source in M 101, 4XMM J140314.2541806 (henceforth, J1403), using Chandra and XMM-Newton data. Over the las…
