要旨:
We have made extensive observations of 35 distant slow (non-recycled) pulsars
discovered in the ongoing Arecibo PALFA pulsar survey. Timing observations of
these pulsars over several years at Arecibo Observatory and Jodrell Bank
Observatory have yielded high-precision positions and measurements of rotation
properties. Despite being a relatively distant population, these pulsars have
properties that mirror those of the previously known pulsar population. Many of
the sources exhibit timing noise, and one underwent a small glitch. We have
used multifrequency data to measure the interstellar scattering properties of
these pulsars. We find scattering to be higher than predicted along some lines
of sight, particularly in the Cygnus region. Lastly, we present XMM-Newton and
Chandra observations of the youngest and most energetic of the pulsars,
J1856+0245, which has previously been associated with the GeV-TeV pulsar wind
nebula HESS J1857+026.
