Astronomers have found the largest pair of black hole jets ever seen, stretching a staggering 23 million light-years across space. To put that into perspective, these jets are about 240 times the diamter of our Milky Way galaxy (~100 thousand Read More …
A new version of the XMM-Newton EPIC Serendipitous Source Catalogue, 4XMM-DR14, has been released by the XMM-Newton Survey Science Centre (XMM-SSC) in collaboration with the XMM-Newton SOC. This version includes an extra year of data with respect to 4XMM-DR13. 4XMM-DR14 Read More …
The Space-based multi-band astronomical Variable Objects Monitor (SVOM) is the first joint Franco-Chinese mission that was launched successfully on June 22nd 2024 from China’s Xichang Satellite Launch Center. It is the result of a collaboration between the two national space Read More …
Astronomers using data from European Space Agency’s Gaia mission have found the most massive stellar black hole in our own galaxy. This black hole was identified because it imposed an unstable and bizarre movement of its companion star orbiting it. Read More …
Kilonovae are luminous explosions that result from the merger of two neutron stars. These rare phenomena are characterised by the emission of an intense gamma-ray burst (GRB). Gamma rays have the smallest wavelengths and the most energy of any wavelength Read More …
The @eROSITA_SRG consortium has unleashed the colossal first #eROSITA X-ray telescope data release to the public with a record-breaking 900,000 cosmic sources & ~50 scientific publications. Among the 900,000 sources more than 700,000 are supermassive black holes in the center Read More …
The X-ray Imaging and Spectroscopy Mission (XRISM) is a space telescope launched in September 2023 and led by the Japan Aerospace Exploration Agency (JAXA), in collaboration with NASA with additional contributions from the European Space Agency. It will study some of the Read More …
Cosmic rays are highly energetic subatomic particles (usually a proton) that travel with speed very close to the speed of light. Their energy range from around 1 GeV (this is the energy of a relatively small particle accelerator) to as Read More …
A tidal disruption event (or as it’s well known as “TDE”) is an astronomical phenomenon that happens when a star passes sufficiently close to a supermassive black hole and the enormous gravitational force (tidal force) of the black hole pulls Read More …
The centre of the Milky Way Galaxy hosts a black hole (Sagittarius A* (Sgr A)) of about 4 million the mass of the Sun. Because of its mass, our own galaxy is considered as very “calm” at present, compared to those Read More …
