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…
