EMU discovery of Thunder: a bow-shock PWN powered by PSR J1631-4722 escaping Nimbus SNR (G336.7+0.5)
S. LazareviÄ, C. Maitra, A. Ahmad +21
We report the discovery of a bow-shock pulsar wind nebula (PWN), dubbed Thunder, powered by the radio pulsar PSR J1631-4722 and projected within the Galactic supernova remnant (SNR…
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…
A newly born spider system at the core of a radio shell: Evidence for a low-energy supernova
S. LazareviÄ, R. Brose, L. M. Oskinova +24
In a search for low surface brightness radio nebulae using the ASKAP-EMU survey, we discovered a faint radio shell, G289.6+5.8, and its central point radio source at the position o…
The Intermediate Mass Black Hole in Omega Centauri: Constraints on Accretion from JWST
Steven Chen, Jeremy Hare, Oleg Kargaltsev +4
We analyze JWST observations of the central region of the globular cluster Centauri (NGC 5139, Cen hereafter), around the position of the candidate IMBH inferred by \cite…
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…
