XMM-Newton observations of SDSS J143030.22001115.1: an unusually flat spectrum AGN
S. Mathur, E. C. Golowacz, R. Williams +3
We present XMM observations of the AGN SDSS 1430-0011. The low S/N spectrum of this source obtained in a snap shot Chandra observation showed an unusually flat continuum. With the…
Emergence of a Broad-Absorption-Line Outflow in the Narrow-line Seyfert 1 Galaxy WPVS 007
Karen M. Leighly, Fred Hamann, Darrin A. Casebeer +1
We report results from a 2003 FUSE observation, and reanalysis of a 1996 HST observation of the unusual X-ray transient Narrow-line Seyfert 1 galaxy WPVS 007. The HST FOS spectrum…
Late-time detections of the X-ray afterglow of GRB 060729 with Chandra - the latest detections ever of an X-ray afterglow
Dirk Grupe, David N. Burrows, Xue-Feng Wu +8
We report on 5 Chandra observations of the X-ray afterglow of the Gamma-Ray Burst GRB 060729 performed between 2007 March and 2008 May. In all five observations the afterglow is cl…
Black Hole Masses of Intermediate-Redshift Quasars: Near Infrared Spectroscopy
Matthias Dietrich, Smita Mathur, Dirk Grupe +1
We present near-infrared spectra of ten luminous, intermediate redshift quasars observed with SofI at the NTT of ESO/La Silla. With these rest-frame optical spectra we probe the Hb…
X-ray Absorption and Optical Extinction in the Partially Obscured Seyfert Nucleus in Mrk 1393
T. G. Wang, H. Y. Zhou, D. Grupe +3
We present a detailed study of the X-ray and optical spectra of the luminous Seyfert galaxy Mrk 1393, which revealed variable partial obscuration of the active nucleus. The X-ray s…
