The non-thermal superbubble in IC 10: the generation of cosmic ray electrons caught in the act
Volker Heesen, Elias Brinks, Martin G. H. Krause +6
Superbubbles are crucial for stellar feedback, with supposedly high (of the order of 10 per cent) thermalization rates. We combined multiband radio continuum observations from the…
Direction Dependent Effects In Wide-Field Wideband Full Stokes Radio Imaging
Preshanth Jagannathan, Sanjay Bhatnagar, Urvashi Rau +1
Synthesis imaging in radio astronomy is affected by instrumental and atmospheric effects which introduce direction-dependent (DD) gains.The antenna power pattern varies both as a f…
Wideband VLA Observations of Abell 2256 I: Continuum, Rotation Measure and Spectral Imaging
Frazer Owen, Lawrence Rudnick, Jean Eilek +3
We report new observations of Abell 2256 with the Karl G. Jansky Very Large Array (VLA) at frequencies between 1 and 8 GHz. These observations take advantage of the 2:1 bandwidths…
Wideband Mosaic Imaging with the VLA - quantifying faint source imaging accuracy
Urvashi Rau, Sanjay Bhatnagar, Frazer N. Owen
A large number of deep and wide-field radio interferometric surveys are being designed to measure accurate statistics of faint source populations. Most require mosaic observations,…
