CASA, the Common Astronomy Software Applications for Radio Astronomy
THE CASA TEAM, Ben Bean, Sanjay Bhatnagar +46
CASA, the Common Astronomy Software Applications, is the primary data processing software for the Atacama Large Millimeter/submillimeter Array (ALMA) and the Karl G. Jansky Very La…
The CASA software for radio astronomy: status update from ADASS 2019
B. Emonts, R. Raba, G. Moellenbrock +28
CASA, the Common Astronomy Software Applications package, is the primary data processing software for the Atacama Large Millimeter/submillimeter Array (ALMA) and NSF's Karl G. Jans…
A joint deconvolution algorithm to combine single dish and interferometer data for wideband multi-term and mosaic imaging
Urvashi Rau, Nikhil Naik, Timothy Braun
Imaging in radio astronomy is usually carried out with a single-dish radio telescope doing a raster scan of a region of the sky or with an interferometer that samples the visibilit…
Direction Dependent Corrections in Polarimetric Radio Imaging I : Characterizing the effects of the primary beam on full Stokes imaging
P. Jagannathan, S. Bhatnagar, U. Rau +1
Next generation radio telescope arrays are being designed and commissioned to accurately measure polarized intensity and rotation measures across the entire sky through deep, wide-…
Understanding Systematic Errors Through Modeling of ALMA Primary Beams
Kara Kundert, Urvashi Rau, Edwin Bergin +1
Many aspects of the Atacama Large Millimeter Array (ALMA) instrument are still unknown due to its young age. One such aspect is the true nature of the primary beam of each baseline…
EVLA Observations of Galactic Supernova Remnants: Wide-field Continuum and Spectral-index Imaging
S. Bhatnagar, U. Rau, D. A. Green +1
The radio continuum emission from the Galaxy has a rich mix of thermal and non-thermal emission. This very richness makes their interpretation challenging since the low radio opaci…
