Published on Nature Communications the work led by Samuele Ronchini, PhD student at GSSI and INFN associate, together with INAF, which sheds new light on cooling processes happening in jets of Gamma-Ray Bursts. What are the processes that determine the Read More …
After the discovery of quasars (QSO), in the mid-1960s the X-ray astronomy started and was important to understand better the nature and the properties of the Active Galactic Nuclei (AGN), as the X-ray emission seemed to occur in the majority Read More …
A new panorama from NASA’s Chandra X-ray Observatory and the MeerKAT radio telescope provides a stunning view of the center of our Milky Way galaxy. It also reveals threads of superheated gas and magnetic fields, which are weaving a tapestry Read More …
The Athena (Advanced Telescope for High ENergy Astrophysics) mission is the second long-range space mission (L2) of the long term program “Cosmic Vision” of the European Space Agency (ESA). This mission is dedicated to the scientific theme “The hot and Read More …
Black holes are divided, based on their mass, into supermassive black holes (SMBHs) with masses more than 1 million Suns together that reside in the centre of the galaxies and stellar black holes with masses up to 20 times the Read More …

Tracing back a ghostly particle from a star-shredding supermassive black hole, scientists have uncovered a gigantic cosmic particle accelerator. Some 700 million years ago, subatomic particles called neutrinos were hurled at nearly the speed of light toward Earth as a Read More …
Astronomers using NASA’s Chandra X-ray Observatory have announced the discovery of an important type of titanium blasting out from the center of the supernova remnant Cas A, a result that could be a major advance in understanding how some massive Read More …
