A Flexible Method of Estimating Luminosity Functions
Brandon C. Kelly, Xiaohui Fan, Marianne Vestergaard
We describe a Bayesian approach to estimating luminosity functions. We derive the likelihood function and posterior probability distribution for the luminosity function, given the…
The Role of Galactic Winds on Molecular Gas Emission from Galaxy Mergers
Desika Narayanan, T. J. Cox, Brandon Kelly +7
We assess the impact of starburst and AGN feedback-driven winds on the CO emission from galaxy mergers, and, in particular, search for signatures of these winds in the simulated CO…
Gemini Near-infrared Spectroscopy of Luminous z~6 Quasars: Chemical Abundances, Black Hole Masses, and MgII Absorption
Linhua Jiang, Xiaohui Fan, Marianne Vestergaard +4
We present Gemini near-infrared spectroscopic observations of six luminous quasars at z=5.86.3. Five of them were observed using Gemini-South/GNIRS, which provides a simultan…
Spitzer observations of a 24 micron shadow: Bok Globule CB190
Amelia M. Stutz, John H. Bieging, George H. Rieke +8
We present Spitzer observations of the dark globule CB190 (L771). We observe a roughly circular 24 micron shadow with a 70 arcsec radius. The extinction profile of this shadow matc…
The Radio-Loud Fraction of Quasars is a Strong Function of Redshift and Optical Luminosity
Linhua Jiang, Xiaohui Fan, Zeljko Ivezic +4
Using a sample of optically-selected quasars from the Sloan Digital Sky Survey, we have determined the radio-loud fraction (RLF) of quasars as a function of redshift and optical lu…
