  • Discovery, Timing, and Multiwavelength Observations of the Black Widow Millisecond Pulsar PSR J1555-2908 
    Ray, Paul S.; Nieder, Lars; Clark, Colin J.; Ransom, Scott M.; Cromartie, H. Thankful; Frail, Dale A.; Mooley, Kunal P.; Intema, Huib; Jagannathan, Preshanth; Demorest, Paul; Stovall, Kevin; Halpern, Jules P.; Deneva, Julia; Guillot, Sebastien; Kerr, Matthew; Swihart, Samuel J.; Bruel, Philippe; Stappers, Ben W.; Lyne, Andrew; Mickaliger, Mitch; Camilo, Fernando; Ferrara, Elizabeth C.; Wolff, Michael T.; Michelson, P.F. (London : Institute of Physics Publ., 2022)
    We report the discovery of PSR J1555-2908, a 1.79 ms radio and gamma-ray pulsar in a 5.6 hr binary system with a minimum companion mass of 0.052 M ⊙. This fast and energetic ( Ė=3×1035 erg s-1) millisecond pulsar was first ...
  • Is the Black-widow Pulsar PSR J1555-2908 in a Hierarchical Triple System? 
    Nieder, L.; Kerr, M.; Clark, C.J.; Bruel, P.; Cromartie, H.T.; Ransom, S.M.; Ray, P.S. (London : Institute of Physics Publ., 2022)
    The 559 Hz black-widow pulsar PSR J1555-2908, originally discovered in radio, is also a bright gamma-ray pulsar. Timing its pulsations using 12 yr of Fermi-Large Area Telescope gamma-ray data reveals long-term variations ...
  • Serendipitous Discovery of Three Millisecond Pulsars with the GMRT in Fermi-directed Survey and Follow-up Radio Timing 
    Bhattacharyya, B.; Roy, J.; Freire, P.C.C.; Ray, P.S.; Johnson, T.J.; Gupta, Y.; Bhattacharya, D.; Kaninghat, A.; Ferrara, E.C.; Michelson, P.F. (London : Institute of Physics Publ., 2022)
    We report the discovery of three millisecond pulsars (MSPs): PSRs J1120-3618, J1646-2142, and J1828+0625 with the Giant Metrewave Radio Telescope (GMRT) at a frequency of 322 MHz using a 32 MHz observing bandwidth. These ...
