Abstract:

One of the biggest successes of the Fermi Large Area Telescope has been its ability to discover pulsars in blind searches of the gamma-ray data. Here we report the discovery of two new energetic pulsars, using ten years of LAT data. The pulsars, thought to be powering the supernova remnants MSH 11-62 (G291.0-0.1) and CTB 37A (G348.5+0.1) share many characteristics, including their young characteristic age, energetic nature, and noisy/glitchy behavior, making their pulsations challenging to find. We report results on these two pulsars based on the gamma-ray analysis, as well as some preliminary findings from X-ray and radio observations.
