Torque reversal and orbital profile of X-ray pulsar OAO 1657-415
Zhenxuan Liao, Jiren Liu, Peter A. Jenke +1
OAO 1657-415 is an atypical supergiant X-ray binary among wind-fed and disk-fed systems, showing alternate spin-up/spin-down intervals lasting on the order of tens of days. We stud…
Fermi-GBM Observations of GRB 210812A: Signatures of a Million Solar Mass Gravitational Lens
P. Veres, N. Bhat, N. Fraija +1
Observing gravitationally lensed objects in the time domain is difficult, and well-observed time-varying sources are rare. Lensed gamma-ray bursts (GRBs) offer improved timing prec…
Comparison of Anomalous and Galactic Cosmic Ray Oxygen at 1 au during 1997-2020
Shuai Fu, Lingling Zhao, Xiaoping Zhang +2
Using quiet-time measurements of element oxygen within the energy range 7.3--237.9 MeV nuc from the ACE spacecraft at 1 au, we compare the energy spectra and intensities of…
Low-efficiency long gamma-ray bursts: A case study with AT2020blt
Nikhil Sarin, Rachel Hamburg, Eric Burns +3
The Zwicky Transient Facility recently announced the detection of an optical transient AT2020blt at redshift , consistent with the afterglow of an on-axis gamma-ray burst. H…
Disk vs wind accretion in X-ray pulsar GX 301-2
Jiren Liu, Long Ji, Peter A. Jenke +8
GX 301-2 provides a rare opportunity to study both disk and wind accretion in a same target. We report Insight-HXMT observations of the spin-up event of GX 301-2 happened in 2019 a…
The Fermi GBM Gamma-Ray Burst Spectral Catalog: 10 Years of Data
S. Poolakkil, R. Preece, C. Fletcher +17
We present the systematic spectral analyses of gamma-ray bursts (GRBs) detected by the Fermi Gamma-Ray Burst Monitor (GBM) during its first ten years of operation. This catalog con…
GRB 191016A: A Long Gamma-Ray Burst Detected by TESS
Krista Lynne Smith, Ryan Ridden-Harper, Michael Fausnaugh +8
The TESS exoplanet-hunting mission detected the rising and decaying optical afterglow of GRB 191016A, a long Gamma-Ray Burst (GRB) detected by Swift-BAT but without prompt XRT or U…
Identification of a Local Sample of Gamma-Ray Bursts Consistent with a Magnetar Giant Flare Origin
E. Burns, D. Svinkin, K. Hurley +23
Cosmological Gamma-Ray Bursts (GRBs) are known to arise from distinct progenitor channels: short GRBs mostly from neutron star mergers and long GRBs from a rare type of core-collap…
The X-ray pulsar XTE J1858+034 observed with NuSTAR and Fermi/GBM: spectral and timing characterization plus a cyclotron line
C. Malacaria, P. Kretschmar, K. K. Madsen +7
Accreting X-ray pulsars (XRPs) undergo luminous X-ray outbursts during which the spectral and timing behavior of the neutron star can be studied in detail. We analyze a ob…
Rapid Spectral Variability of a Giant Flare from a Magnetar in NGC 253
O. J. Roberts, P. Veres, M. G. Baring +18
Magnetars are slowly-rotating neutron stars with extremely strong magnetic fields ( G), episodically emitting ms long X-ray bursts with energies of $\sim10^{4…
A bright gamma-ray flare interpreted as a giant magnetar flare in NGC 253
D. Svinkin, D. Frederiks, K. Hurley +33
Magnetars are young, highly magnetized neutron stars that produce extremely rare giant flares of gamma-rays, the most luminous astrophysical phenomena in our Galaxy. The detection…
