The Swift satellite lives up to its name, revealing cosmic explosions as they happen.
Gamma-ray bursts are the most powerful objects in the Universe. Discovered in the 1960s as brief flashes of gamma radiation, we now know that they emit across the entire electromagnetic spectrum, are located in distant galaxies and comprise two distinct populations, one of which may originate in the deaths of massive stars. The launch of the Swift satellite in 2004 brought a flurry of new disco...
متن کاملVesicle formation: Dynamic dynamin lives up to its name
The GTP-binding protein dynamin was initially thought to be required for just the final stages of clathrin-dependent vesicle formation, but recent results indicate that it can actually catalyse many of the essential steps in the vesiculation pathway.
متن کاملCosmic Explosions (Optical)
One of the principal motivations of wide-field and synoptic surveys is the search for, and study of, transients. By transients I mean those sources that arise from the background, are detectable for some time, and then fade away to oblivion. Transients in distant galaxies need to be sufficiently bright as to be detectable, and in almost all cases those transients are catastrophic events, markin...

متن کاملAstrophysical explosions: from solar flares to cosmic gamma-ray bursts
Astrophysical explosions result from the release of magnetic, gravitational or thermonuclear energy on dynamical time scales, typically the sound-crossing time for the system. These explosions include solar and stellar flares, eruptive phenomena in accretion discs, thermonuclear combustion on the surfaces of white dwarfs and neutron stars, violent magnetic reconnection in neutron stars, thermon...
