X-ray spectral and flux variability of the microquasar GRS 1758-258 on timescales from weeks to years
Maria Hirsch, Katja Pottschmidt, David M. Smith +12
We present the spectral and timing evolution of the persistent black hole X-ray binary GRS 1758-258 based on almost 12 years of observations using the Rossi X-ray Timing Explorer P…
Simultaneous observations of the blazar PKS2155-304 from Ultra-Violet to TeV energies
H. E. S. S., Fermi, NuSTAR collaborations
The results of the first ever contemporaneous multi-wavelength observation campaign on the BL Lac object PKS2155-304 involving Swift, NuSTAR, Fermi-LAT and H.E.S.S. are reported. T…
Detection of the 511 keV Galactic positron annihilation line with COSI
Carolyn A. Kierans, Steven E. Boggs, Andreas Zoglauer +10
The signature of positron annihilation, namely the 511 keV -ray line, was first detected coming from the direction of the Galactic center in the 1970's, but the source of Galact…
MAXI J1820+070 with NuSTAR I. An increase in variability frequency but a stable reflection spectrum: coronal properties and implications for the inner disc in black hole binaries
D. J. K. Buisson, A. C. Fabian, D. Barret +10
MAXI J1820+070 (optical counterpart ASASSN-18ey) is a black hole candidate discovered through its recent very bright outburst. The low extinction column and long duration at high f…
Modeling the precession of the warped inner accretion disk in the pulsars LMC X-4 and SMC X-1 with NuSTAR and XMM-Newton
McKinley C. Brumback, Ryan C. Hickox, Felix S. Fürst +3
We present a broad-band X-ray study of the effect of superorbital periods on X-ray spectra and pulse profiles in the neutron star X-ray binaries LMC X-4 and SMC X-1. These two sour…
Discovery and Identification of MAXI J1621-501 as a Type I X-ray Burster with a Super-Orbital Period
Nicholas M. Gorgone, Chryssa Kouveliotou, Hitoshi Negoro +26
MAXI J1621-501 is the first Swift/XRT Deep Galactic Plane Survey transient that was followed up with a multitude of space missions (NuSTAR, Swift, Chandra, NICER, INTEGRAL, and MAX…
High Density Reflection Spectroscopy: II. the Density of the Inner Black Hole Accretion Disc in AGN
Jiachen Jiang, Andrew C. Fabian, Thomas Dauser +7
We present a high density disc reflection spectral analysis of a sample of 17 Seyfert 1 galaxies to study the inner disc densities at different black hole mass scales and accretion…
Quasi-simultaneous radio and X-ray observations of Aql X-1: probing low luminosities
N. V. Gusinskaia, J. W. T. Hessels, N. Degenaar +8
Aql X-1 is one of the best-studied neutron star low-mass X-ray binaries. It was previously targeted using quasi-simultaneous radio and X-ray observations during at least 7 differen…
Conflicting disk inclination estimates for the black hole X-ray binary XTE J1550-564
Riley~M. ~T. ~Connors, Javier~A. ~Garcia, James~F. ~Steiner +7
XTE J1550-564 is a black hole X-ray binary for which the dynamical characteristics are well established, and the broadband spectral evolution of the source has been well studied. I…
Search for gravitational-wave signals associated with gamma-ray bursts during the second observing run of Advanced LIGO and Advanced Virgo
B. P. Abbott, R. Abbott, T. D. Abbott +1196
We present the results of targeted searches for gravitational-wave transients associated with gamma-ray bursts during the second observing run of Advanced LIGO and Advanced Virgo,…
Evolution of the extended X-ray emission from the PSR B1259-63/LS 2883 binary in the 2014-2017 binary cycle
Jeremy Hare, Oleg Kargaltsev, George G. Pavlov +1
We have performed a series of Chandra X-ray Observatory observations of the gamma-ray binary LS 2883, which is comprised of a young pulsar (PSR B1259-63) orbiting a massive Be star…
All at once: transient pulsations, spin down and a glitch from the Pulsating Ultraluminous X-ray Source M82 X-2
Matteo Bachetti, Thomas J. Maccarone, Murray Brightman +9
M82 X-2 is the first pulsating ultraluminous X-ray source (PULX)to be identified. Since the discovery in 2014, NuSTAR has observed the M82 field 15 times throughout 2015 and 2016.…
SN 2016coi (ASASSN-16fp): an energetic H-stripped core-collapse supernova from a massive stellar progenitor with large mass loss
G. Terreran, R. Margutti, D. Bersier +25
We present comprehensive observations and analysis of the energetic H-stripped SN 2016coi (a.k.a. ASASSN-16fp), spanning the -ray through optical and radio wavelengths, acquired…
Revisiting the Fe XVII line emission problem: laboratory measurements of the 3s-2p and 3d-2p line-formation channels
Chintan Shah, José R. Crespo López-Urrutia, Ming Feng Gu +5
We determined relative X-ray photon emission cross sections in Fe XVII ions that were mono-energetically excited in an electron beam ion trap. Line formation for the 3s (3s-2p) and…
