Estimating the peak energy of Swift gamma-ray bursts using supervised machine learning
Wan-Peng Sun, Si-Yuan Zhu, Da-Ling Ma +1
Gamma-ray bursts (GRBs) are among the most energetic explosive phenomena in the Universe, and their peak energy () is a key physical quantity for understanding the promp…
Radio Variable and Transient Sources on Minute Timescales in the ASKAP Pilot Surveys
Yuanming Wang, Tara Murphy, Emil Lenc +12
We present results from a radio survey for variable and transient sources on 15-min timescales, using the Australian SKA Pathfinder (ASKAP) pilot surveys. The pilot surveys consist…
Multi-wavelength view of the close-by GRB 190829A sheds light on gamma-ray burst physics
O. S. Salafia, M. E. Ravasio, J. Yang +12
Gamma-ray bursts are produced as a result of cataclysmic events such as the collapse of a massive star or the merger of two neutron stars. We monitored the position of the close-by…
Transition from Fireball to Poynting-flux-dominated Outflow in Three-Episode GRB 160625B
B. -B. Zhang, B. Zhang, A. J. Castro-Tirado +51
The ejecta composition is an open question in gamma-ray bursts (GRB) physics. Some GRBs possess a quasi-thermal spectral component in the time-resolved spectral analysis, suggestin…
Temporal evolution of long-timescale periodicities in ULX NGC 5408 X-1
Tao An, Xiang-Long Lu, Jun-Yi Wang
Context. NGC 5408 X-1 is one of the few ultraluminous X-ray sources with an extensive monitoring program in X-rays (a temporal baseline of 4.2 yr), making it one of the most suitab…
Confirming the 115.5-day periodicity in the X-ray light curve of ULX NGC 5408 X-1
Xu Han, Tao An, Jun-Yi Wang +5
The Swift/XRT light curve of the ultraluminous X-ray (ULX) source NGC 5408 X-1 was re-analyzed with two new numerical approaches, Weighted Wavelet -transform (WWZ) and CLEANest,…
