Further Evidence for a Supermassive Black Hole Mass - Pitch Angle Relation
Joel C. Berrier, Benjamin L. Davis, Daniel Kennefick +7
We present new and stronger evidence for a previously reported relationship between galactic spiral arm pitch angle P (a measure of the tightness of spiral structure) and the mass…
Identification of Outflows and Candidate Dual Active Galactic Nuclei in SDSS Quasars at z=0.8-1.6
R. Scott Barrows, Claud H. Sandberg Lacy, Julia Kennefick +3
We present a sample of 131 quasars from the Sloan Digital Sky Survey at redshifts 0.8<z<1.6 with double peaks in either of the high-ionization narrow emission lines [NeV]3426 or [N…
Do floating orbits in extreme mass ratio binary black holes exist?
Shasvath J. Kapadia, Daniel Kennefick, Kostas Glampedakis
This paper examines the possibility of floating or non-decaying orbits for extreme mass ratio binary black holes. In the adiabatic approximation, valid in the extreme mass ratio ca…
