For more than two decades, astronomers have been systematically tracing mystery sources of high-energy gamma rays to their sources. One, however, remained stubborn – the brightest unidentified source of gamma rays in the Milky Way. It seemed to be coming from Read More …
The covid-19 situation suspended all the visits on site, though the visits in EGO and Virgo will be LIVE BROADCASTED from the time beeing! Stay tuned! Galileo’s telescope opened the door to the stars, EGO and Virgo opened a new Read More …
A rare blast of light, emitted by a star as it is sucked in by a supermassive black hole, has been spotted by scientists using telescopes from around the world. The phenomenon, known as a tidal disruption event, is the Read More …
A team of gravitational wave researchers led by the ARC Center of Excellence for Gravitational Wave Discovery (OzGrav) report that when two black holes collide and merge, the remnant black hole “chirps” not once, but multiple times, emitting gravitational waves—intense Read More …
The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics 2020 with one half to Roger Penrose, University of Oxford, UK, “for the discovery that black hole formation is a robust prediction of the general Read More …
An analysis of archival X-ray data from NASA’s Rossi X-Ray Timing Explorer has revealed a clear separation between the characteristics of stellar-mass black holes and neutron stars, which is a consequence of the lack of the hard surface in the Read More …
The first massive galaxy groups in the Universe are predicted to have formed when the Universe was less than 4 billions years old (redshift > 2). Baryonic physics, like stellar and active galactic nuclei (AGN) feedback in this very active Read More …
Scientists with the Hard X-ray Modulation Telescope (Insight-HXMT) team has performed extensive observations of the accreting X-ray pulsar GRO J1008-57 and has discovered a magnetic field of ~1 billion Tesla on the surface of the neutron star. This is the Read More …
Astronomers have used NASA’s Chandra X-ray Observatory to record material blasting away from the site of an exploded star at speeds faster than 20 million miles per hour. This is about 25,000 times faster than the speed of sound on Read More …
For a long time astronomers have puzzled over the lack of observations of compact objects with masses ranging from 2.5 up to 5 solar masses. This mysterious grey area is known as the ‘mass gap’: a range of masses apparently Read More …
