  1. 102. Joint Pulsar Studies with the FAST Radio Telescope and the Fermi LAT
    Dr Pablo Saz Parkinson (University of California, Santa Cruz)

    Contributed Talk

    The Five-hundred-meter Aperture Spherical radio Telescope (FAST) is a Chinese megascience facility built by the National Astronomical Observatories (NAOC) of the Chinese Academy of Sciences (CAS). Completed in 2016, FAST is the world's largest single-dish radio telescope, and is currently operating as an international facility, with regular proposal calls open to observers from around the...

  3. 146. The high-energy gamma-ray emission of globular clusters

    Contributed Talk

    There are now 35 confirmed gamma-ray bright globular clusters (GCs) in the Milky Way. The millisecond pulsar (MSP) populations within these clusters are widely considered to be their primary source of gamma-ray emission. There are two proposed mechanisms for high-energy gamma-rays to be created in GCs by MSPs. The first is radiation from charged particles traveling along the open magnetic...

  4. 147. Origin of pulsar radio emission

    Contributed Talk

    For more than five decades, the origin of pulsar radio emission have been one of the
    major unsolved problems in astrophysics. It is universally believed that generation
    of radio emission is intimately connected with pair plasma production initiated by
    high energy gamma-rays in pulsar polar caps. Here I will present the results of our
    study of electron-positron pairs creation near magnetic...

  6. 48. Constraining the multipolar magnetic field of millisecond pulsar PSR J0030+0451 via NICER X-ray light curve fitting

    Contributed Talk

    The Neutron star Interior Composition Explorer (NICER) has been operating since 2017 with the major aim of gaining a better understanding of the extreme nature of neutron stars (NSs). With its exceptional sensitivity, it hopes to constrain the equation of state of NSs to high precision. Modelling thermal X-ray light curves (LCs) of pulsars can provide us with insights into the magnetic field...

  7. 136. Multiwavelength observations of the variable gamma-ray pulsar PSR J2021+4026
    Massimiliano Razzano
    Contributed Talk

    PSR J2021+4026 in the Cygnus region is one of the most interesting radio-quiet pulsars detected by Fermi-LAT. This source, thought to be associated with the Gamma Cygni supernova remnant, is the first isolated gamma-ray pulsar that exhibited clear evidence of variability, with a simultaneous flux and spindown change first occurred in October 2011. After a long recovery phase, in August 2015...

  8. 135. Strong Lensing of Confined Magnetar Burst Fireballs
    Dr Zorawar Wadiasingh (University of Maryland College Park/ NASA GSFC / NWU)
    Contributed Talk

    Fermi GBM has a catalog of many hundreds of magnetar bursts. These bursts are short in duration, quasi-thermal in spectrum and exhibit complex spectro-temporal behavior suggestive of Comptonized fireballs. Recent report of rotational-phase selection of magnetar short bursts in SGR 1830-0645 and SGR 1935+2154 strongly suggest a fixed and low altitude emission locale for magnetic flux tubes...
