Galactic Compact Objects Section of the White Paper on the Status and Future of Ground-based TeV Gamma-ray Astronomy
P. Kaaret, A. A. Abdo, J. Arons +22
This is a report on the findings of the Galactic compact objects working group for the white paper on the status and future of TeV gamma-ray astronomy. The white paper is an APS co…
The wind nebula around magnetar Swift J1834.9-0846
G. Younes, C. Kouveliotou, O. Kargaltsev +12
We report on the analysis of two deep XMM-Newton observations of the magnetar Swift J1834.9-0846 and its surrounding extended emission taken in March 2014 and October 2014, 2.5 and…
On the puzzling high-energy pulsations of the energetic radio-quiet -ray pulsar J18131246
M. Marelli, A. Harding, D. Pizzocaro +6
We have analyzed the new deep {\it XMM-Newton} and {\it Chandra} observations of the energetic radio-quiet pulsar J18131246. The X-ray spectrum is non-thermal, very hard and abs…
Gamma Rays and Gravitational Waves
E. Burns, S. Zhu, C. M. Hui +28
The first multimessenger observation of a neutron star merger was independently detected in gamma-rays by Fermi-GBM and INTEGRAL SPI-ACS and gravitational waves by Advanced LIGO an…
Correlation between X-ray Lightcurve Shape and Radio Arrival Time in the Vela Pulsar
A. Lommen, J. Donovan, C. Gwinn +6
We report the results of simultaneous observations of the Vela pulsar in X-rays and radio from the RXTE satellite and the Mount Pleasant Radio Observatory in Tasmania. We sought co…
The High Energy X-ray Probe (HEX-P): Magnetars and Other Isolated Neutron Stars
J. A. J. Alford, G. A. Younes, Z. Wadiasingh +23
The hard X-ray emission from magnetars and other isolated neutron stars remains under-explored. An instrument with higher sensitivity to hard X-rays is critical to understanding th…
The Apache Point Observatory Galactic Evolution Experiment (APOGEE) Spectrographs
J. C. Wilson, F. R. Hearty, M. F. Skrutskie +86
We describe the design and performance of the near-infrared (1.51--1.70 micron), fiber-fed, multi-object (300 fibers), high resolution (R = lambda/delta lambda ~ 22,500) spectrogra…
Science with e-ASTROGAM (A space mission for MeV-GeV gamma-ray astrophysics)
A. De Angelis, V. Tatischeff, I. A. Grenier +248
e-ASTROGAM (enhanced ASTROGAM) is a breakthrough Observatory space mission, with a detector composed by a Silicon tracker, a calorimeter, and an anticoincidence system, dedicated t…
High-Resolution Timing Observations of Spin-Powered Pulsars with the AGILE Gamma-Ray Telescope
A. Pellizzoni, M. Pilia, A. Possenti +67
AGILE is a small gamma-ray astronomy satellite mission of the Italian Space Agency dedicated to high-energy astrophysics launched in 2007 April. Its 1 microsecond absolute time tag…
Spectrum and extension of the inverse-Compton emission of the Crab Nebula from a combined Fermi-LAT and H.E.S.S. analysis
F. Aharonian, F. Ait Benkhali, J. Aschersleben +158
The Crab Nebula is a unique laboratory for studying the acceleration of electrons and positrons through their non-thermal radiation. Observations of very-high-energy rays from…
Correlations between pulsed X-ray flux and radio arrival time in the Vela pulsar
A. N. Lommen, J. Donovan, C. Gwinn +6
We report the results of simultaneous observations of the Vela pulsar in X-rays and radio from the RXTE satellite and the Mount Pleasant Radio Observatory in Tasmania. We sought co…
High-Precision X-ray Timing of Three Millisecond Pulsars with NICER: Stability Estimates and Comparison with Radio
J. S. Deneva, P. S. Ray, A. Lommen +45
The Neutron Star Interior Composition Explorer (NICER) is an X-ray astrophysics payload on the International Space Station. It enables unprecedented high-precision timing of millis…
