Drop in the hard pulsed fraction and a candidate cyclotron line in IGR J16320-4751 seen by NuSTAR
Arash Bodaghee, Alan J. -L. Chiu, John A. Tomsick +10
We report on a timing and spectral analysis of a 50-ks NuSTAR observation of IGR J16320-4751 (= AX J1631.9-4752); a high-mass X-ray binary hosting a slowly-rotating neutron star. I…
Chandra Observations of High Energy X-ray Sources Discovered by INTEGRAL
John A. Tomsick, Arash Bodaghee, Sylvain Chaty +6
The International Gamma-Ray Astrophysics Laboratory (INTEGRAL) satellite has detected in excess of 1000 sources in the ~20-100 keV band during its surveys of the sky over the past…
Chandra, MDM, Swift, and NuSTAR observations confirming the SFXT nature of AX J1949.8+2534
Jeremy Hare, Jules P. Halpern, Maica Clavel +3
AX J1949.8+2534 is a candidate supergiant fast X-ray transient (SFXT) observed in outburst by INTEGRAL (IGR J19498+2534). We report on the results of six Neil Gehrels Swift-XRT, on…
Chandra Observations of NuSTAR Serendipitous Sources near the Galactic Plane
John A. Tomsick, George B. Lansbury, Farid Rahoui +8
The NuSTAR serendipitous survey has already uncovered a large number of Active Galactic Nuclei (AGN), providing new information about the composition of the Cosmic X-ray Background…
The evolving jet spectrum of the neutron star X-ray binary Aql X-1 in transitional states during its 2016 outburst
M. Diaz Trigo, D. Altamirano, T. Dincer +7
We report on quasi-simultaneous observations from radio to X-ray frequencies of the neutron star X-ray binary Aql X-1 over accretion state transitions during its 2016 outburst. All…
The Ultra-Fast Outflow of the Quasar PG 1211+143 as Viewed by Time-Averaged Chandra Grating Spectroscopy
Ashkbiz Danehkar, Michael A. Nowak, Julia C. Lee +8
We present a detailed X-ray spectral study of the quasar PG 1211+143 based on Chandra High Energy Transmission Grating Spectrometer (HETGS) observations collected in a multi-wavele…
