Galaxy Ellipticity Measurements in the Near-Infrared for Weak Lensing
Bomee Lee, Ranga-Ram Chary, Edward L. Wright
We investigate the value of the near-infrared imaging from upcoming surveys for constraining the ellipticities of galaxies. We select galaxies between 0.5 < z < 3 that are brighter…
The highly polarized dusty emission core of Cygnus A
Enrique Lopez-Rodriguez, Robert Antonucci, Ranga-ram Chary +1
We report the detection of linearly polarized emission at 53 and 89 m, from the radio-loud active galactic nucleus (AGN) Cygnus A using HAWC+ onboard SOFIA. We measure a highly…
Excess in the High Frequency Radio Background: Insights from Planck
Eric J. Murphy, Ranga-Ram Chary
We conduct a stacking analysis using 1.4 GHz NRAO VLA Sky Survey (NVSS) detections and Planck all-sky maps to estimate the differential source counts down to the few 100 Jy leve…
GOODS-ALMA: 1.1 mm galaxy survey - I. Source catalogue and optically dark galaxies
M. Franco, D. Elbaz, M. Béthermin +36
We present a 69 arcmin ALMA survey at 1.1mm, GOODS-ALMA, matching the deepest HST-WFC3 H-band part of the GOODS-South field. We taper the 0"24 original image with a homogeneous…
