GRM Scientific Pipeline
Ping Wang, Li Zhang, Jin Wang +18
The Gamma-Ray Monitor (GRM) is a key payload of the Space-based multiband astronomical Variable Objects Monitor (SVOM) mission, which is designed to detect gamma ray bursts (GRBs)…
Relativistic \(^{56}\text{Ni}\) Decay Lines in GRB 221009A
Rahim Moradi, Emre S. Yorgancioglu, Shao-Lin Xiong +4
Long Gamma Ray Bursts are thought to originate from the core collapse of massive stars that give rise to energetic broad-lined Type Ic supernovae. The brightest burst ever recorded…
Discovery of energy-dependent phase variations in the polarization angle of Cen X-3
Qing-Chang Zhao, Lian Tao, Sergey S. Tsygankov +7
We present a detailed polarimetric analysis of Cen X-3 using \ixpe observations during its high state, revealing complex energy-dependent polarization behavior. While phase-average…
Eclipsed X-ray Bursts from Magnetar SGR J1935+2154 and the Fireball Measurements
Sheng-Lun Xie, Aming Chen, Yun-Wei Yu +17
In theory, burst activity of the magnetar can lead to the formation of fireballs trapped by the magnetic field and corotating with the star. However, the smoking-gun observational…
Detection of Oscillations in a Type I X-Ray Burst of 4U 0614+091 with SVOM/ECLAIRs
Sébastien Le Stum, Floriane Cangemi, Alexis Coleiro +29
On 2025 January 10, a thermonuclear (Type I) X-ray burst from the neutron star low-mass X-ray binary \textit{4U~0614+091} was detected with the ECLAIRs instrument on board the \tex…
The First X-ray Polarimetry of GRS 1739--278 Reveals Its Rapidly Spinning Black Hole
Qing-Chang Zhao, Michal Dovciak, Han-Cheng Li +6
We present a joint spectro-polarimetric analysis of the black hole X-ray binary GRS~1739--278 during its 2025 mini-outburst, using simultaneous observations from \ixpe\ and \nustar…
