Scale Invariance in Gamma-Ray Flares of the Sun and 3C 454.3
The Astrophysical Journal, 2023 Using the gamma-ray flare samples of the Sun and 3C 454.3 observed by the Fermi telescope, we investigate the statistical properties of sizes including fluence (energy), peak flux (luminosity), duration time, and waiting time in this work.

GRB 070201: A Possible Soft Gamma‐Ray Repeater in M31 [PDF]
The Astrophysical Journal, 2008 The gamma-ray burst (GRB) 070201 was a bright short-duration hard-spectrum GRB detected by the Inter-Planetary Network (IPN). Its error quadrilateral, which has an area of 0.124 sq. deg, intersects some prominent spiral arms of the nearby M31 (Andromeda) galaxy.

GECAM Localization of High-energy Transients and the Systematic Error
The Astrophysical Journal Supplement Series, 2023 The Gravitational Wave High-energy Electromagnetic Counterpart All-sky Monitor (GECAM) is a pair of microsatellites (i.e., GECAM-A and GECAM-B) dedicated to monitoring gamma-ray transients including the high-energy electromagnetic counterparts of ...

The Fermi Gamma-ray Burst Monitor: Results from the first two years [PDF]
, 2011 In the first two years since the launch of the Fermi Observatory, the Gamma-ray Burst Monitor (GBM) has detected over 500 Gamma-Ray Bursts (GRBs), of which 18 were confidently detected by the Large Area Telescope (LAT) above 100 MeV.

Unveiling soft gamma-ray repeaters with INTEGRAL
Astrophysics and Space Science, 2007 Thanks to INTEGRAL's long exposures of the Galactic Plane, the two brightest Soft Gamma-Ray Repeaters, SGR 1806-20 and SGR 1900+14, have been monitored and studied in detail for the first time at hard-X/soft gamma rays. This has produced a wealth of new scientific results, which we will review here.

SOFT GAMMA REPEATERS AND ANOMALOUS X-RAY PULSARS BEYOND MAGNETARS
Odessa Astronomical Publications, 2016 The observational properties of Soft Gamma Repeaters and Anomalous X-ray Pulsars (SGR/AXP) indicate to necessity of the energy source different from a rotational energy of a neutron star.

The Astrophysical Journal, 2023 Magnetars are believed to be neutron stars (NSs) with strong magnetic fields. X-ray flares and fast radio bursts (FRBs) have been observed from the magnetar (soft gamma-ray repeater, SGR J1935+2154).

Spectral effects of the vacuum resonance in soft gamma-ray repeaters [PDF]
Monthly Notices of the Royal Astronomical Society, 1997 The association of all three soft gamma-ray repeaters (SGRs) with supernova remnants has established that SGRs are young neutron stars, and has given us a starting point for detailed modeling. One of the most popular classes of models involves strongly magnetised neutron stars, with surface dipole fields B~ 10^{14}-10^{15} Gauss.

Imprints of Superfluidity on Magnetoelastic Quasiperiodic Oscillations of Soft Gamma-Ray Repeaters [PDF]
Physical Review Letters, 2013 Our numerical simulations show that axisymmetric, torsional, magnetoelastic oscillations of magnetars with a superfluid core can explain the whole range of observed quasiperiodic oscillations (QPOs) in the giant flares of soft gamma-ray repeaters. There exist constant phase QPOs at f is < or approximately equal to 150 Hz and resonantly excited high ...
