Red nuggets grow inside-out: evidence from gravitational lensing

Kavli Affiliate: Philip Marshall | First 5 Authors: Lindsay Oldham, Matt Auger, Chris Fassnacht, Tommaso Treu, Brendon J. Brewer | Summary: We present a new sample of strong gravitational lens systems where both the foreground lenses and background sources are early-type galaxies. Using imaging from HST/ACS and Keck/NIRC2, we model the surface brightness distributions and […]

Accurate Polarization Calibration at 800 MHz with the Green Bank Telescope

Kavli Affiliate: Kiyoshi Wesley Masui | First 5 Authors: Yu-Wei Liao, Tzu-Ching Chang, Cheng-Yu Kuo, Kiyoshi Wesley Masui, Niels Oppermann | Summary: Polarization leakage of foreground synchrotron emission is a critical issue in HI intensity mapping experiments. While the sought-after HI emission is unpolarized, polarized foregrounds such as Galactic and extragalactic synchrotron radiation, if coupled […]

Systematic Study of Gamma-ray bright Blazars with Optical Polarization and Gamma-ray Variability

Kavli Affiliate: Grzegorz M. Madejski | First 5 Authors: Ryosuke Itoh, Krzysztof Nalewajko, Yasushi Fukazawa, Makoto Uemura, Yasuyuki T. Tanaka | Summary: Blazars are highly variable active galactic nuclei which emit radiation at all wavelengths from radio to gamma-rays. Polarized radiation from blazars is one key piece of evidence for synchrotron radiation at low energies […]
