TLDR
In this paper, the authors present a compilation of properties of 105,783 quasars in the Sloan Digital Sky Survey Data Release 7 (DR7) quasar catalog, including radio properties, and flags indicating broad absorption line properties.Abstract:
We present a compilation of properties of the 105,783 quasars in the Sloan Digital Sky Survey Data Release 7 (DR7) quasar catalog. In this product, we compile continuum and emission line measurements around the Hα, Hβ, Mg II, and C IV regions, as well as other quantities such as radio properties, and flags indicating broad absorption line quasars, disk emitters, etc. We also compile virial black hole mass estimates based on various calibrations. For the fiducial virial mass estimates we use the Vestergaard & Peterson (VP06) calibrations for Hβ and C IV, and our own calibration for Mg II which matches the VP06 Hβ masses on average. We describe the construction of this catalog and discuss its limitations. The catalog and its future updates will be made publicly available online.read more

The power of relativistic jets is larger than the luminosity of their accretion disks
TL;DR: An analysis of archival observations of a sample of blazars (quasars whose jets point towards Earth) that overcomes previous limitations finds a clear correlation between jet power, as measured through the γ-ray luminosity, and accretion luminosity; this implies that the magnetic field threading the black hole horizon reaches the maximum value sustainable by the accreting matter.

The diversity of quasars unified by accretion and orientation
Yue Shen,Yue Shen,Luis C. Ho +2 more
TL;DR: The results show that most of the diversity of quasar phenomenology can be unified using two simple quantities: Eddington ratio and orientation, and find that orientation plays a significant role in determining the observed kinematics of the gas in the broad-line region.

The relationship between infrared, optical, and ultraviolet extinction
TL;DR: In this article, the average extinction law over the 3.5 micron to 0.125 wavelength range was derived for both diffuse and dense regions of the interstellar medium. And the validity of the law over a large wavelength interval suggests that the processes which modify the sizes and compositions of grains are stochastic in nature.
