Another look at the size of the low-surface brightness galaxy VCC 1661 in the Virgo Cluster
Andreas Koch, Christine S. Black, R. Michael Rich +3
We present new wide-field images of the low-surface brightness Virgo Cluster dwarf galaxy VCC 1661. The extant literature lists a broad range of radii for this object, covering a f…
The Intrinsic Eddington Ratio Distribution of Active Galactic Nuclei in Star-forming Galaxies from the Sloan Digital Sky Survey
M. L. Jones, R. C. Hickox, C. S. Black +3
An important question in extragalactic astronomy concerns the distribution of black hole accretion rates of active galactic nuclei (AGN). Based on observations at X-ray wavelengths…
Progressive Red Shifts in the Late-Time Spectra of Type Ia Supernovae
C. S. Black, R. A. Fesen, J. T. Parrent
We examine the evolution of late-time, optical nebular features of Type Ia supernovae (SNe Ia) using a sample consisting of 160 spectra of 27 normal SNe Ia taken from the literatur…
