The X-ray pulsars were discovered in the 70s and are among the most luminous objects in the X-ray sky. They are binary systems that consist of a magnetized neutron star in orbit with a normal stellar companion. The magnetic field Read More …
White dwarfs are among the most stable of stars. Left on their own, these stars that have exhausted most of their nuclear fuel — while still typically as massive as the Sun — and shrunk to a relatively small size Read More …
Description Massive spectroscopic datasets, in the form of IFU datacubes and large surveys consisting of thousands of spectra, have begun to stream into archives on a daily basis, and will soon include observations from NIRSpec and MIRI aboard JWST. Creating Read More …
The massive galaxies and a fraction of lower mass galaxies in the Local Universe host a super massive black hole (SMBH) in their centre. They have masses between millions to 10 billions times the mass of the Sun. When matter Read More …
Galaxy clusters are the largest objects in the universe held together by gravity. They typically contain hundreds of galaxies (stars, gas and dust), spread over a region of whose size is roughly 1025 cm. Their total masses exceed 1048 gm. Read More …
Beginning in April 2021, the CTA Observatory (CTAO) launched its new monthly webinar series “Journey through the Extreme Universe” livestreamed via the CTA YouTube and Facebook channels. The webinars have the main goal to take you on a journey through Read More …
