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…
A radio structure resolved at the deca-parsec scale in radio-quiet quasar PDS 456 with an extremely powerful X-ray outflow
Jun Yang, Tao An, Fang Zheng +5
Active galactic nuclei (AGN) accreting at rates close to the Eddington limit can host radiatively driven mildly relativistic outflows. Some of these X-ray absorbing but powerful ou…
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 --…
Revealing two radio active galactic nuclei extremely near PSR J04374715
Zhixuan Li, Jun Yang, Tao An +9
Newton's gravitational constant may vary with time at an extremely low level. The time variability of will affect the orbital motion of a millisecond pulsar in a binary sys…
Imaging and variability studies of CTA~102 during the 2016 January -ray flare
Xiaofeng Li, P. Mohan, T. An +6
The -ray bright blazar CTA 102 is studied using imaging (new 15 GHz and archival 43 GHz Very Long Baseline Array, VLBA data) and time variable optical flux density, polarization…
