The Host Galaxy of the Quasar HE 0450-2958
Minjin Kim, Luis C. Ho, Chien Y. Peng +1
A recent study suggests that the quasar HE 0450-2958 is hosted by a galaxy substantially fainter than that inferred from the correlation between black hole mass and bulge luminosit…
Radio Emission on Sub-Parsec Scales from the Intermediate-Mass Black Hole in NGC 4395
J. M. Wrobel, L. C. Ho
The Seyfert 1 nucleus of NGC 4395 is energized by a black hole of 360,000 Solar masses (Peterson et al.), making it one of only two nuclear black holes of intermediate mass, one th…
Stellar populations in the nuclei of late-type spiral galaxies
Carl-Jakob Walcher, Torsten Boeker, Stephane Charlot +5
(Abridged) As part of an ongoing effort to study the stellar nuclei of very late-type, bulge-less spirals, we present results from a high-resolution spectroscopic survey of nine su…
Constraints on the Star Formation Rate in Active Galaxies
Minjin Kim, Luis C. Ho, Myungshin Im
The [O II] 3727 emission line is often used as an indicator of star formation rate in extragalactic surveys, and it can be an equally effective tracer of star formation in systems…
