Signatures of Intra-binary shock emission in the black widow pulsar binary PSR J2241-5236

Hongjun An, Roger W. Romani, Matthew Kerr

We report on high-energy properties of the black widow pulsar PSR J2241 $-$ 5236 in the X-ray and the Fermi-LAT (GeV gamma-ray) bands. In the LAT band, the phase-averaged gamma-ray l…

Flux Relaxation after two outbursts of the magnetar SGR 1627 $-$ 41 and possible hard X-ray emission

Hongjun An, Andrew Cumming, Victoria M. Kaspi

We report on the long-term flux relaxation of the magnetar SGR 1627-41 after its 2008 outburst, and evidence for hard X-ray excess measured with NuSTAR. We use new observations mad…

SED constraints on the highest- $z$ blazar jet: QSO J0906+6930

Hongjun An, Roger W. Romani

We report on Gemini, NuSTAR and 8-year Fermi observations of the most distant blazar QSO~J0906 $+$ 6930 ( $z = 5.48$ ). We construct a broadband spectral energy distribution (SED) and mo…
