GBT24B-288

Complete the Drift Scan Survey for Gas in Galaxies, the Milky Way, PSRs & FRBs

Abstract

The goal of the GBT Drift scan survey has been to produce a Nyquist-sampled L-band spectral-line map of a region of sky between 15 hr < RA < 0 hr, and +45 < Dec < +50 deg, while simultaneously searching for pulsars, Fast Radio Bursts and other radio transients. The effort is to maximize scientific yield from a period of time when the telescope is otherwise not utilized due to movement restrictions imposed to facilitate its summer maintenance. While 2018 & 2019 observations focused on pulsar searches, partially covering the area at full-beam-width separations, full-Nyquist sampling is required for localizing extra-galactic sources via their HI and Radio Recombination lines. The data so-gathered also allows Galactic HI and OH studies. So far, about 42 percent of the area has been covered at full spatial sampling. A spectral-line data analysis pipeline has progressed considerably during the summer of 2023.
Work on a new Pulsar-Search Collaboratory database is also underway. This new endeavor is designed to increase student involvement in the search for Fast Radio Bursts and Pulsars. Hence, we request that this drift-scan survey utilizes the "summer maintenance 2024" to complete the survey.
