Chandra X-ray Observations of the Pulsar Wind Nebula within CTA 1
Seth Gagnon, Oleg Kargaltsev, Jason Alford +2
We present deep Chandra observations of the pulsar wind nebula (PWN) powered by PSR J0007+7303 in the composite supernova remnant CTA 1. The merged ACIS image shows a je…
Multi-mission Investigation of X-ray Superorbital Modulation in the Supergiant High Mass X-ray Binary 4U 1538-52
H. I. Cohen, N. Islam, R. H. D. Corbet +7
Superorbital modulations has been detected in the supergiant High-Mass X-ray binary 4U 1538-52 using long-term monitoring with the Neil Gehrels Swift Observatory Burst Alert Telesc…
The nature of UHE source 1LHAASO J1740+0948u and its connection to PSR J1740+1000
Seth Gagnon, Yichao Lin, Alexander Lange +4
We present multi-wavelength analysis of 1LHAASO J1740+0948u and its surroundings including the pulsar wind nebula of middle-aged pulsar PSR J1740+1000. Although a dozen X-ray sourc…
The Vela pulsar and its pulsar wind nebula Vela-X using 13 years of Fermi-LAT Observations
Alexander Lange, J. Eagle, O. Kargaltsev +2
We present results of more than 13 years of Fermi-LAT data analysis for the Vela pulsar from 60 MeV to 100 GeV and its pulsar wind nebula (PWN), Vela-X, for E > 1 GeV in the off-pu…
Orbital Phase-resolved Analysis of X-ray and Gamma-ray Observations of the High-Mass Gamma-ray Binary 4FGL J1405.1-6119
Alexander Lange, Robin H. D. Corbet, Joel B. Coley +4
We present the results of multi-wavelength observations of the High-Mass Gamma-Ray Binary 4FGL J1405.1-6119. A pair of joint XMM-Newton and NuSTAR observations taken in 2019 (sampl…
