A new way to 'weigh' extragalactic black holes
... energetic photons at optical, ultraviolet, and X-ray wavelengths. These X-ray sources have been mistaken in the past for fast Gamma Ray Bursts (GRBs), however these energetic bursts are short-lived, while the X-ray flares on the other hand persist...

Telescope targets enigmatic deep space mystery
...has hinted towards a new phenomenon, be it pulsars or gamma-ray bursts. One such ‘bump’ came to light in 2007, when...Without a doubt, the key to understanding these enigmatic bursts lies in localisation, and observations at additional wavelengths would...

New studies reveal the origin of fast radio bursts
... waves have been detected. This lack of simultaneous emissions in other wavelengths suggests FRBs associated with short gamma-ray bursts are rare, say Zhang and colleagues. Zhang and team did not miss out entirely on FRBs...

Exploring the extreme universe
... Universe are transient, i.e., they last a limited amount of time, from fractions of seconds to a few hours. For example gamma-ray bursts - the brightest electromagnetic events which can typically outshine the rest of the high-energy Universe - can...

Researchers probe black-hole mergers with fast-powered winds
... merger. Indeed, just 0.4s after GW 150914 was detected, observations with Fermi’s Gamma-ray Burst Monitor (GBM) revealed the presence of a weak short-duration gamma-ray burst (GRB) event with a false alarm probability of 0.0022. Its localisation was...

New constellations for Fermi's 10th birthday
..., Maryland. “One way or another, all of the gamma-ray constellations have a tie-in to Fermi science.” Among the ... the new constellations are from gamma-ray sources, such as supermassive black holes, gamma-ray bursts and the debris of supernova ...
