Space Telescope and Optical Reverberation Mapping Project. V. Optical Spectroscopic Campaign and Emission-Line Analysis for NGC 5548
L. Pei, M. M. Fausnaugh, A. J. Barth +153
We present the results of an optical spectroscopic monitoring program targeting NGC 5548 as part of a larger multi-wavelength reverberation mapping campaign. The campaign spanned s…
Recalibration of the Relation for AGN
Merida Batiste, Misty C. Bentz, Sandra I. Raimundo +2
We present a re-calibration of the relation, based on a sample of 16 reverberation-mapped galaxies with newly determined bulge stellar velocity dispersions ($σ_{…
Serendipitous discovery of a projected pair of QSOs separated by 4.5 arcsec on the sky
K. E. Heintz, J. P. U. Fynbo, J. -K. Krogager +8
We present the serendipitous discovery of a projected pair of quasi-stellar objects (QSOs) with an angular separation of arcsec. The redshifts of the two QSOs are widely…
Black-hole masses of distant quasars
M. Vestergaard
A brief overview of the methods commonly used to determine or estimate the black hole mass in quiescent or active galaxies is presented and it is argued that the use of mass-scalin…
High-Redshift SDSS Quasars with Weak Emission Lines
Aleksandar M. Diamond-Stanic, Xiaohui Fan, W. N. Brandt +14
We identify a sample of 74 high-redshift quasars (z>3) with weak emission lines from the Fifth Data Release of the Sloan Digital Sky Survey and present infrared, optical, and radio…
