Title: The Location of Young Pulsar PSR J0837−2454: Galactic Halo or Local Supernova Remnant?
Authors: Nihan Pol et al.
First Author’s Institution: West Virginia University; Vanderbilt University
Status: Published in ApJ

In 1967, a graduate student named Jocelyn Bell Burnell discovered the first pulsar, opening a window into a universe teeming with many wild and wonderful varieties of these extreme objects. Pulsars are fast-spinning neutron stars with powerful magnetic fields, emitting beams of radio waves. They give rise to many interesting phenomena: some pulsars cannibalize companion stars, others emit pulses of high-energy gamma rays, and still others exhibit sudden changes in their rotation period.
Despite this diversity, pulsar astronomers have managed to establish some typical properties of pulsars. For example, pulsars — especially very young pulsars — are rarely found far from the plane of the Milky Way. The stars that form them usually live in the galactic disk, and many pulsars ...
