Recent results on Gamma-Ray Bursts obtained with the X-ray Astronomy satellite BeppoSAX are reviewed. Main emphasis is given to the GRBs simultaneously detected with the Gamma-Ray Burst Monitor (40-700 keV) and the Wide Field Cameras (1.5-26 keV). These bursts were rapidly localized with ...

456Gamma-ray Bursts: 15 Years of GRB Afterglowsnormal SN Ic not associated with GRBs (Pianet al.2006; Mazzaliet al.2006).GRB 060218 was an underluminous burst, as were two of the other three previouscases. Because of the low luminosity, these events are only detected when nearbyand are...
Gravitational wave astronomy opened dramatically in September 2015 with the LIGO discovery of a distant and massive binary black hole coalescence. The more recent discovery of a binary neutron star merger, followed by a gamma ray burst (GRB) and a kilonova, reinforces the excitement of this new...
The deexcitation recoil energy of the \gamma _0 transition was negligible, and the maximum Doppler shift was 17.3-63.4 keV for E_\text{p} = 1.4-4.3 MeV. \gamma ray energies can be higher than 11 MeV; therefore, the ^{27}Al(p,\gamma)^{28}Si resonance reactions at E_\text{p} =...
The Burst Alert Telescope (BAT) on the Swift Gamma-Ray Burst MIDEX mission has detected more than 200 gamma-ray bursts (GRBs), nearly all of which have been followed up by the narrow-field instruments on Swift through automatic repointing, and by ground and other satellite telescopes after ...

ray binaries, hard X-ray emission mechanism in pulsars, and gamma-ray bursts. They also highlight an increase in polarization with energy, which makes hard X-ray polarimetry extremely appealing. There are a number of confirmed hard X-ray polarimetry experiments which along with the existing ...
Abstract Ischemic stroke is a common disease with a high disability rate and mortality, which brings heavy pressure on families and medical insurance. Nowadays, the golden treatments for ischemic stroke in the acute phase mainly include endovascular therapy and intravenous thrombolysis. Some drugs are ...
