Modeling the light curves of ultraluminous X-ray sources as precession
T. Dauser, M. Middleton, J. Wilms
We present a freely available xspec model for the modulations seen in the long-term light curves of multiple ultraluminous X-ray sources (ULXs). By incorporating the physics of mul…
Search for high-energy neutrinos from bright GRBs with ANTARES
A. Albert, M. André, M. Anghinolfi +125
Gamma-ray bursts are thought to be sites of hadronic acceleration, thus neutrinos are expected from the decay of charged particles, produced in pγ interactions. The methods and res…
Results from the search for dark matter in the Milky Way with 9 years of data of the ANTARES neutrino telescope
A. Albert, M. André, M. Anghinolfi +125
Using data recorded with the ANTARES telescope from 2007 to 2015, a new search for dark matter annihilation in the Milky Way has been performed. Three halo models and five annihila…
GRS 1739-278 observed at very low luminosity with XMM-Newton and NuSTAR
F. Fuerst, J. A. Tomsick, K. Yamaoka +19
We present a detailed spectral analysis of XMM-Newton and NuSTAR observations of the accreting transient black hole GRS 1739-278 during a very faint low hard state at ~0.02% of the…
Cyclotron resonant scattering feature simulations. I. Thermally averaged cyclotron scattering cross sections, mean free photon-path tables, and electron momentum sampling
F. -W. Schwarm, G. Schoenherr, S. Falkner +11
Electron cyclotron resonant scattering features (CRSFs) are observed as absorption-like lines in the spectra of X-ray pulsars. A significant fraction of the computing time for Mont…
Time-dependent search for neutrino emission from x-ray binaries with the ANTARES telescope
A. Albert, M. André, G. Anton +115
ANTARES is currently the largest neutrino telescope operating in the Northern Hemisphere, aiming at the detection of high-energy neutrinos from astrophysical sources. Neutrino tele…
The NuSTAR X-ray Spectrum of Hercules X-1: A Radiation-Dominated Radiative Shock
Michael T. Wolff, Peter A. Becker, Amy M. Gottlieb +7
We report new spectral modeling of the accreting X-ray pulsar Hercules X- 1. Our radiation-dominated radiative shock model is an implementation of the analytic work of Becker & Wol…
Stacked search for time shifted high energy neutrinos from gamma ray bursts with the ANTARES neutrino telescope
ANTARES Collaboration, S. Adrian-Martínez, A. Albert +118
A search for high-energy neutrino emission correlated with gamma-ray bursts outside the electromagnetic prompt-emission time window is presented. Using a stacking approach of the t…
Two giant outbursts of V 0332+53 observed with INTEGRAL
C. Ferrigno, L. Ducci, E. Bozzo +7
In July 2015, the high-mass X-ray binary V 0332+53 underwent a giant outburst, a decade after the previous one. This system hosts a strongly magnetized neutron star. During the 200…
The Soft State of Cygnus X-1 Observed with NuSTAR: A Variable Corona and a Stable Inner Disk
D. J. Walton, J. A. Tomsick, K. K. Madsen +17
We present a multi-epoch hard X-ray analysis of Cygnus X-1 in its soft state based on four observations with NuSTAR. Despite the basic similarity of the observed spectra, there is…
Spectro-timing study of GX 339-4 in a hard intermediate state
F. Fuerst, V. Grinberg, J. A. Tomsick +16
We present an analysis of NuSTAR observations of a hard intermediate state of the transient black hole GX 339-4 taken in January 2015. As the source softened significantly over the…
High-Density Effects in X-ray Reflection Models from Accretion Disks
Javier A. García, Andrew C. Fabian, Timothy R. Kallman +5
Current models of the spectrum of X-rays reflected from accretion disks around black holes and other compact objects are commonly calculated assuming that the density of the disk a…
Evidence for an Evolving Cyclotron Line Energy in 4U 1538-522
Paul B. Hemphill, Richard E. Rothschild, Felix Fürst +6
We have performed a full time- and luminosity-resolved spectral analysis of the high-mass X-ray binary 4U 1538-522 using the available RXTE, INTEGRAL, and Suzaku data, examining bo…
Coincidence of a high-fluence blazar outburst with a PeV-energy neutrino event
M. Kadler, F. Krauß, K. Mannheim +40
The discovery of extraterrestrial very-high-energy neutrinos by the IceCube collaboration has launched a quest for the identification of their astrophysical sources. Gamma-ray blaz…
