NuSTAR spectral analysis beyond 79 keV with stray light
G. Mastroserio, B. W. Grefenstette, P. Thalhammer +10
Due to the structure of the NuSTAR telescope, photons at large off-axis (> 1deg) can reach the detectors directly (stray light), without passing through the instrument optics. At t…
The long stare at Hercules X-1 -- I. Emission lines from the outer disk, the magnetosphere boundary and the accretion curtain
P. Kosec, E. Kara, A. C. Fabian +11
Hercules X-1 is a nearly edge-on accreting X-ray pulsar with a warped accretion disk, precessing with a period of about 35 days. The disk precession allows for unique and changing…
Polarized x-rays constrain the disk-jet geometry in the black hole x-ray binary Cygnus X-1
Henric Krawczynski, Fabio Muleri, Michal Dovčiak +111
A black hole x-ray binary (XRB) system forms when gas is stripped from a normal star and accretes onto a black hole, which heats the gas sufficiently to emit x-rays. We report a po…
Orbital decay in M82 X-2
Matteo Bachetti, Marianne Heida, Thomas Maccarone +21
M82 X-2 is the first pulsating ultraluminous X-ray source (PULX) discovered. The luminosity of these extreme pulsars, if isotropic, implies an extreme mass transfer rate. An altern…
Relativistic X-ray Reflection Models for Accreting Neutron Stars
Javier A. Garcia, Thomas Dauser, Renee Ludlam +4
We present new reflection models specifically tailored to model the X-ray radiation reprocessed in accretion disks around neutron stars, in which the primary continuum is character…
An accreting pulsar with extreme properties drives an ultraluminous x-ray source in NGC 5907
G. L. Israel, A. Belfiore, L. Stella +20
Ultraluminous x-ray sources (ULXs) in nearby galaxies shine brighter than any X-ray source in our Galaxy. ULXs are usually modeled as stellar-mass black holes (BHs) accreting at ve…
The Transient Accereting X-Ray Pulsar XTE J1946+274: Stability of the X-Ray Properties at Low Flux and Updated Orbital Solution
Diana M. Marcu-Cheatham, Katja Pottschmidt, Matthias Kühnel +19
We present a timing and spectral analysis of the X-ray pulsar XTE J1946+274 observed with Suzaku during an outburst decline in 2010 October and compare with previous results. XTE J…
The complex accretion geometry of GX 339-4 as seen by NuSTAR and Swift
F. Fuerst, M. A. Nowak, J. A. Tomsick +19
We present spectral analysis of five NuSTAR and Swift observations of GX 339-4 taken during a failed outburst in summer 2013. These observations cover Eddington luminosity fraction…
On Estimating the High-Energy Cutoff in the X-ray Spectra of Black Holes via Reflection Spectroscopy
Javier A. Garcia, Thomas Dauser, James F. Steiner +3
The fundamental parameters describing the coronal spectrum of an accreting black hole are the slope of the power-law continuum and the energy at which it rolls over.…
LOFT: the Large Observatory For X-ray Timing
M. Feroci, J. W. den Herder, E. Bozzo +245
The LOFT mission concept is one of four candidates selected by ESA for the M3 launch opportunity as Medium Size missions of the Cosmic Vision programme. The launch window is curren…
