Temporal Variation in Excited Fe^+ Near a GRB Afterglow
Miroslava Dessauges-Zavadsky, Hsiao-Wen Chen, Jason X. Prochaska +2
Excited Si^+ and Fe^+ species are routinely observed in the host environment of gamma-ray burst (GRB) afterglows, but are not commonly seen in other extragalactic locations. Their…
An Intermediate-Mass Black Hole in the Dwarf Seyfert 1 Galaxy POX 52
A. J. Barth, L. C. Ho, W. L. W. Sargent
We describe new observations of POX 52, a previously known but nearly forgotten example of a dwarf galaxy with an active nucleus. While POX 52 was originally thought to be a Seyfer…
Evidence for Asphericity in the Type IIn Supernova 1998S
Douglas C. Leonard, Alexei V. Filippenko, Aaron J. Barth +1
We present optical spectropolarimetry obtained at the Keck-II 10-m telescope on 1998 March 7 UT along with total flux spectra spanning the first 494 days after discovery (1998 Marc…
Polarized Broad-Line Emission from Low-Luminosity Active Galactic Nuclei
A. J. Barth, A. V. Filippenko, E. C. Moran
In order to determine whether unified models of active galactic nuclei apply to low-luminosity objects, we have undertaken a spectropolarimetric survey of of LINERs and Seyfert nuc…
