Timing and Interstellar Scattering of 35 Distant Pulsars Discovered in the Palfa Survey

A study of 35 distant, slow pulsars discovered through the Arecibo PALFA survey reveals that their properties closely mirror those of known pulsar populations, despite their distance. The research, conducted using timing observations from Arecibo and Jodrell Bank observatories, identified significant interstellar scattering in some regions, notably Cygnus, exceeding predictions. Additionally, XMM-Newton and Chandra observations of the youngest and most energetic pulsar, J1856+0245, linked it to the GeV–TeV pulsar wind nebula HESS J1857+026. The findings highlight the utility of multi-frequency data in probing interstellar phenomena and pulsar behavior.
