GBT19A-474

Drift Scan Survey for Pulsars, FRBs, Radio Transients, and Gas in Galaxies

Abstract

Our goal is to perform drift scans using the 342 MHz, 800 MHz, and L-Band receivers during GBT filler time. One of these three configurations will be assigned depending on receiver availability. The configurations will be similar to the drift scans performed in 2016 and 2018, with suitable time and frequency resolution for discovering pulsars and transient sources to large distances. Simultaneous spectral line observations will be taken whenever using the L-band receiver to search for galaxies via their $\lambda$ 21 cm HI emission. The observations will require minimal monitoring by the operator once they have been started. General oversight of the observations will be managed by the Green Bank Observatory team members. For pulsar searches, high time-resolution data will be copied from Green Bank directly to WVU using the high-speed link, so as to not congest the available storage space at Green Bank. This data will be processed on a high performance cluster at WVU and students of the PSC program will inspect plots to identify candidate pulsars, FRBs, and other transient sources. The HI data will be copied to an external drive and reduced at Green Bank using GBTIDL.
