Radio pulsar death

, 2002
Pulsar radio emission is believed to be originated from the electron-positron pairs streaming out from the polar cap region. Pair formation, an essential condition for pulsar radio emission, is believed to be sustained in active pulsars via one photon process from either the curvature radiation (CR) or the inverse Compton scattering (ICS) seed photons,

The variability of radio pulsars

, 2015
Neutron stars are amongst the most exotic objects known in the universe; more than a solar mass of material is squeezed into an object the size of a city, leading to a density comparable to that of an atomic nucleus. They have a surface magnetic field which is typically around a trillion times stronger than the magnetic field here on Earth, and we have

Einstein@Home Searches for Gamma-Ray Pulsars in the Inner Galaxy

The Astrophysical Journal
The Fermi Large Area Telescope (LAT) has revealed a mysterious extended excess of GeV gamma-ray emission around the Galactic Center (GC), which can potentially be explained by unresolved emission from a population of pulsars, particularly millisecond ...

Radio Emission across the Entire Rotation Phases of Pulsars

The Astrophysical Journal
Supersensitive observations of bright pulsars by the Five-hundred-meter Aperture Spherical Telescope have revealed weak radio emission continuously emerges in the rotation phases between the “main” pulse and “interpulse” of a rotating neutron star.
