PSR J1813-1749 is one of the most energetic rotation-powered pulsars known, producing a pulsar wind nebula (PWN) and gamma-ray and TeV emission, but whose spin period is only measurable in X-ray. We present analysis of two Chandra datasets that are separated by more than ten years and recent NICER data. The long baseline of the Chandra data allows us to derive a pulsar proper motion μ R.A. = - ( 0 . ″ 067 ± 0 . ″ 010 ) yr-1 and μ decl. = - ( 0 . ″ 014 ± 0 . ″ 007 ) yr-1 and velocity v ⊥ ≈ 900…

Radio Proper Motions of the Energetic Pulsar PSR J1813–1749
PSR J1813–1749 has peculiarities that make it a very interesting object of study. It is one of the most energetic and the most scattered pulsars known. It is associated with HESS J1813–178, one of
Radio Detection of PSR J1813–1749 in HESS J1813–178: The Most Scattered Pulsar Known
The 44.7 ms X-ray pulsar in the supernova remnant G12.82−0.02/HESS J1813−178 has the second highest spin-down luminosity of known pulsars in the Galaxy, with Ė=5.6×1037 erg s−1. Using the Green Bank
Süpernova Kalıntısı G12.8-0.0’nin Suzaku ile X-ışın Dalgaboylarında Araştırılması
The Galactic supernova remnant (SNR) G12.8-0.0 is a member of the class of composite SNRs and hosts the pulsar PSR J1813–1749. In this work, we investigate the X-ray nature of the emission and
Search for long-duration transient gravitational waves from glitching pulsars during LIGO—Virgo third observing run
Pulsars are spinning neutron stars which emit an electromagnetic beam. We expect pulsars to slowly decrease their rotational frequency. However, sudden increases of the rotational frequency have been


Two new X-ray timing observations of the 44.7 ms pulsar in G12.82-0.02/HESS J1813-178 were obtained with Chandra and XMM-Newton to determine its precise spin-down rate. With a period derivative of
Discovery of a Highly Energetic X-Ray Pulsar Powering HESS J1813-178 in the Young Supernova Remnant G12.82-0.02
We report the discovery of 44.7 ms pulsations from the X-ray source CXOU J181335.1–174957 using data obtained with the XMM-Newton Observatory. PSR J1813–1749 lies near the center of the young radio
