1 Nov 2023 | | Abstract: | We present the discovery and timing results of five pulsars discovered in a pilot survey at intermediate Galactic latitudes with the Five-hundred Aperture Spherical Telescope (FAST). Among these pulsars, two belong to the category of millisecond pulsars (MSPs) with spin periods of less than 20,ms. Two others fall under the classification of ’mildly recycled' pulsars, with massive white dwarfs as companions. Remarkably, this small survey, covering an area of 4.7 square degrees, led to the discovery of five pulsars, including four recycled pulsars. Such success underscores the immense potential of future surveys at intermediate Galactic latitudes. In order to assess the potential yield of MSPs, we conducted population simulations and found that both FAST and Parkes new Phased Array Feed surveys, focusing on intermediate Galactic latitudes, have the capacity to uncover several hundred new MSPs. | | Source: | arXiv, 2311.00370 | | Services: | Forum | Review | PDF | Favorites | |
