8 Aug 2019 | | Abstract: | We identified a highly-polarized, steep-spectrum radio source in a deep image
with the Australian Square Kilometre Array Pathfinder (ASKAP) telescope at 888
MHz. After considering and rejecting a stellar origin for this source, we
discovered a new millisecond pulsar (MSP) using observations from the Parkes
radio telescope. This pulsar has period 2.77 ms and dispersion measure 228.27
pc/cm**3. Although this pulsar does not yet appear to be particularly
remarkable, the short spin period, wide profile and high dispersion measure do
make it relatively hard to discover through traditional blind periodicity
searches. Over the course of several weeks we see changes in the barycentric
period of this pulsar that are consistent with orbital motion in a binary
system, but the properties of any binary need to be confirmed by further
observations. While even a deep ASKAP survey may not identify large numbers of
new MSPs compared to the existing population, it would be competitive with
existing all-sky surveys and could discover interesting new MSPs at high
Galactic latitude without the need for computationally-expensive all-sky
periodicity searches. | | Source: | arXiv, 1908.3163 | | Services: | Forum | Review | PDF | Favorites | |
