ESA’s Euclid mission is designed to explore the composition and evolution of the dark Universe. The space telescope will create a great map of the large-scale structure of the Universe across space and time by observing billions of galaxies out Read More …
Massive galaxies and a fraction of lower mass galaxies in the Local Universe host a super massive black hole in their centre. Their mass ranges between millions and tens billions solar masses. When matter from the galaxies falls into the Read More …
The galaxy Centaurus A (Cen A) shines bright in this image combining data from multiple observatories. In the center of this galaxy is a supermassive black hole feeding off the gas and dust encircling it, and large jets of high-energy Read More …
A team of researchers led by Dr Philip Wiseman from the University of Southampton found the largest and longest cosmic explosion ever happened named AT2021lwx. The explosion is estimated to be ten times brighter than any other supernova so far. Read More …
Astronomers have mapped the hot gas — using X-ray data from Chandra — down to only about 100 light-years from the black hole in the center of the M84 galaxy. A radio image from the VLA reveals jets streaking away Read More …
On December 11, 2021, the Neil Gehrels Swift Observatory satellite observed a gamma-ray burst, named GRB 211211A that is one of the brightest ever observed. Then, ground-based and space-based telescopes started to follow up GRB 211211A to obtain images at Read More …
On Dec. 11, 2021, NASA’s Neil Gehrels Swift Observatory detected a blast of high-energy light from a galaxy roughly 1 billion light-years away. The event, which was simultaneously detected by Fermi Gamma-ray Space Telescope, brings into question what was thought Read More …
Dark matter and energy are not sufficient to explain the formation and evolution of modern galaxies. Violent phenomena, associated with the end of stars (supernovae), mergers of black holes and neutron stars, supermassive black holes accreting mass from the galactic Read More …
The Event Horizon Telescope network has captured the second-ever direct image of a black hole — called Sagittarius A* — at the centre of the Milky Way. Radio astronomers have imaged the super massive black hole at the centre of Read More …
The research developed within AHAED2020 has lead to innovative tools supporting multi-messenger astrophysics! Most of what is known about the Universe comes from observations of electromagnetic radiation. However, there are other “cosmic messengers.” Gravitational waves are invisible (yet incredibly fast) Read More …
