Evidence for Rapid Adiabatic Cooling as an Origin of the Recombining Plasma in the Supernova Remnant W49B Revealed by NuSTAR Observations
Hiroya Yamaguchi, Takaaki Tanaka, Daniel R. Wik +8
X-ray observations of supernova remnants (SNRs) in the last decade have shown that the presence of recombining plasmas is somewhat common in a certain type of object. The SNR W49B…
On the Nature of the X-ray Emission from the Ultraluminous X-ray Source, M33 X-8: New Constraints from NuSTAR and XMM-Newton
Lacey A. West, Bret D. Lehmer, Daniel Wik +12
We present nearly simultaneous NuSTAR and XMM-Newton observations of the nearby (832 kpc) ultraluminous X-ray source (ULX) M33 X-8. M33 X-8 has a 0.3-10 keV luminosity of LX ~ 1.4…
NuSTAR Detection of Nonthermal Bremsstrahlung from the Supernova Remnant W49B
Takaaki Tanaka, Hiroya Yamaguchi, Daniel R. Wik +10
We report on NuSTAR observations of the mixed morphology supernova remnant (SNR) W49B, focusing on its nonthermal emission. Whereas radio observations as well as recent gamma-ray o…
Black Holes and Neutron Stars in Nearby Galaxies: Insights from NuSTAR
Neven Vulic, Ann E. Hornschemeier, Daniel R. Wik +8
Nearby galaxy surveys have long classified X-ray binaries (XRBs) by the mass category of their donor stars (high-mass and low-mass). The NuSTAR observatory, which provides imaging…
Anti-correlation between X-ray luminosity and pulsed fraction in the Small Magellanic Cloud pulsar SXP 1323
Jun Yang, Andreas Zezas, Malcolm J. Coe +4
We report the evidence for the anti-correlation between pulsed fraction (PF) and luminosity of the X-ray pulsar SXP 1323, found for the first time in a luminosity range --…
