Candidate Type II Quasars at 2 < z < 4.3 in the Sloan Digital Sky Survey III
Rachael Alexandroff, Michael A. Strauss, Jenny E. Greene +12
At low redshifts, dust-obscured quasars often have strong yet narrow permitted lines in the rest-frame optical and ultraviolet, excited by the central active nucleus, earning the d…
The Chandra Multi-Wavelength Project: Optical Spectroscopy and the Broadband Spectral Energy Distributions of X-ray Selected AGN
Markos Trichas, Paul J. Green, John D. Silverman +20
From optical spectroscopy of X-ray sources observed as part of ChaMP, we present redshifts and classifications for a total of 1569 Chandra sources from our targeted spectroscopic f…
A spectacular outflow in an obscured quasar
Jenny E. Greene, Nadia L. Zakamska, Paul S. Smith
SDSS J1356+1026 is a pair of interacting galaxies at redshift z=0.123 that hosts a luminous obscured quasar in its northern nucleus. Here we present two long-slit Magellan LDSS-3 s…
The Line Polarization Within a Giant Lyman-alpha Nebula
Moire K. M. Prescott, Paul S. Smith, Gary D. Schmidt +1
Recent theoretical work has suggested that Lyman-alpha nebulae could be substantially polarized in the Lyman-alpha emission line, depending on the geometry, kinematics, and powerin…
Location of gamma-ray Flare Emission in the Jet of the BL Lacertae Object OJ287 more than 14pc from the Central Engine
Ivan Agudo, Svetlana G. Jorstad, Alan P. Marscher +18
We combine time-dependent multi-waveband flux and linear polarization observations with sub-milliarcsecond-scale polarimetric images at lambda=7mm of the BL Lacertae-type blazar OJ…
Probing the Inner Jet of the Quasar PKS 1510-089 with Multi-waveband Monitoring during Strong Gamma-ray Activity
Alan P. Marscher, Svetlana G. Jorstad, Valeri M. Larionov +29
We present results from monitoring the multi-waveband flux, linear polarization, and parsec-scale structure of the quasar PKS 1510-089, concentrating on eight major gamma-ray flare…
