In the last decade there has been growing evidence supporting the coeval growth of galaxies and their resident Supermassive Black Hole (SMBH). However, it is still not clear what are the physical mechanisms that drive the black hole (BH) growth, how the large-scale environment (the mass of their Dark Matter Halo, DMHM) affects these feeding mechanisms and what is the connection between the environment of the SMBH and the host galaxy properties, e.g. Star- Formation Rate (SFR) and stellar mass (M⋆).
More than 200 astronomers collaborated and using the Event Horizon Telescope (EHT) succeeded in taking the first picture of a supermassive black hole!!
Astronomers used data from three X-ray satellites and found a black hole that spins at about 50% the speed of light!
Astronomers used X-ray data from NASA’s Chandra X-ray observatory and ESA’s XMM-Newton satellite as well as ultraviolet data from Sloan Digital Sky survey (SDSS) and found evidence that dark energy is getting stronger with time!!
Scientists used the Fermi telescope to measure the entire amount of starlight ever emitted! According to the measurement, the number of photons (particles of visible light) that escaped into space after being emitted by stars translates to 4×1084!! This is 4 followed by 84 zeros!!!
Ricardo Giacconi, known as the founder of X-ray astronomy, died on Sunday 9th of December at the age of 87.
The X-ray group of IAASARS at NOA, organises a conference in Corfu, Greece, in 19-22 June 2019. The title of the conference is: “Supermassive Black Holes: Environment and Evolution”
Astronomers detected a Gamma Ray Burst (GRB) candidate that its gamma rays were not detected by our telescopes!!
Credit: ESO Astronomers detected flares of infrared radiation coming from Sagittarius A*, the massive object at the heart of our Galaxy, This observation confirms that Sagittarius A* is indeed a supermassive black hole (SMBH)!! The flares were detected using the Read More …
