Wavelet-Based Characterization of Small-Scale Solar Emission Features at Low Radio Frequencies

Posted by dbos MIT

Kavli Affiliate: Robert Goeke | First 5 Authors: Akshay Suresh, Rohit Sharma, Divya Oberoi, Srijan B. Das, Victor Pankratius | Summary: Low radio frequency solar observations using the Murchison Widefield Array have recently revealed the presence of numerous weak, short-lived and narrow-band emission features, even during moderately quiet solar conditions. These non-thermal features occur at […]

Red nuggets grow inside-out: evidence from gravitational lensing

Posted by klaurent Stanford

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

Posted by klaurent MIT

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 […]
