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…
On the Link Between Central Black Holes, Bar Dynamics, and Dark Matter Halos in Spiral Galaxies
Patrick Treuthardt, Marc S. Seigar, Amber D. Sierra +5
The discovery of a relationship between supermassive black hole (SMBH) mass and spiral arm pitch angle (P) is evidence that SMBHs are tied to the overall secular evolution of a gal…
Unusual Double-peaked Emission in the SDSS Quasar J093201.60+031858.7
R. Scott Barrows, Claud H. Sandberg Lacy, Daniel Kennefick +2
We examine spectral properties of the SDSS quasar J093201.60+031858.7, in particular the presence of strong blue peaks in the Balmer emission lines offset from the narrow lines by…
