Description
The VLA Sky Survey images the whole sky at 2-4GHz in the radio with angular resolution comparable to optical telescopes, providing a unique reference survey for the radio sky. Multi-epoch data allows variable sources and transients to be found and characterized and spectral and polarimetric information is also recorded. Processing the large amount of data from this survey is a significant computational challenge as the high resolution of the survey means that subtle calibration and geometric effects need to be carefully treated. In this talk I will describe both some of the multi-messegenger science enabled by VLASS and the computational and logistical challenges of processing VLASS and other NRAO data in HPC/HTC environments.
