Eight-Dimensional Mid-Infrared/Optical Bayesian Quasar Selection
Gordon T. Richards, Rajesh P. Deo, Mark Lacy +11
We explore the multidimensional, multiwavelength selection of quasars from mid-IR (MIR) plus optical data, specifically from Spitzer-IRAC and the Sloan Digital Sky Survey (SDSS). W…
Mid-infrared spectra of optically selected type 2 quasars
Nadia L. Zakamska, Laura Gomez, Michael A. Strauss +1
Type 2 quasars are luminous Active Galactic Nuclei whose central engines are seen through large amounts of gas and dust. We present Spitzer spectra of twelve type 2 quasars selecte…
Hot self-similar relativistic MHD flows
Nadia L. Zakamska, Mitchell C. Begelman, Roger D. Blandford
We consider axisymmetric relativistic jets with a toroidal magnetic field and an ultrarelativistic equation of state, with the goal of studying the lateral structure of jets whose…
Space density of optically-selected type 2 quasars
Reinabelle Reyes, Nadia L. Zakamska, Michael A. Strauss +6
Type 2 quasars are luminous active galactic nuclei (AGN) whose central regions are obscured by large amounts of gas and dust. In this paper, we present a catalog of type 2 quasars…
