Distance Probes of Dark Energy
A. Kim, N. Padmanabhan, G. Aldering +29
This document presents the results from the Distances subgroup of the Cosmic Frontier Community Planning Study (Snowmass 2013). We summarize the current state of the field as well…
Stellar Velocity Dispersion Measurements in High-Luminosity Quasar Hosts and Implications for the AGN Black Hole Mass Scale
C. J. Grier, P. Martini, L. C. Watson +7
We present new stellar velocity dispersion measurements for four luminous quasars with the NIFS instrument and the ALTAIR laser guide star adaptive optics system on the Gemini Nort…
Discovery of a Large Population of Ultraluminous X-ray Sources in the Bulge-less Galaxies NGC 337 and ESO 501-23
Garrett Somers, Smita Mathur, Paul Martini +3
We have used Chandra observations of eight bulge-less disk galaxies to identify new ultraluminous X-ray source (ULX) candidates, study their high mass X-ray binary (HMXB) populatio…
The Origin of Dust in Early-Type Galaxies and Implications for Accretion onto Supermassive Black Holes
Paul Martini, Daniel Dicken, Thaisa Storchi-Bergmann
We have conducted an archival Spitzer study of 38 early-type galaxies (ETGs) in order to determine the origin of the dust in approximately half of this population. Our sample galax…
