An article published in the journal “Astronomy & Astrophysics” describes the discovery of a supermassive black hole pushed out from its galaxy’s core. A team of astronomers led by Marco Chiaberge of the Space Telescope Science Institute in the USA used the Hubble Space Telescope to observe the quasar 3C 186 in which this phenomenon occurred. Another interesting element is that the black hole’s movement may have been accelerated by gravitational waves.

An article published in the journal “Monthly Notices of the Royal Astronomical Society” describes a research on what appears to be a binary system including a star with the closest orbit around a black hole. A team of astronomers used NASA’s Chandra X-ray Observatory and NuSTAR space Telescope and the Australia Telescope Compact Array (ATCA) to observe this system called X9 concluding that the star, a white dwarf, takes 28 minutes to orbit the black hole.
An article published in “The Astrophysical Journal” describes a research on one of the giant gas bubbles regurgitated by the supermassive black hole at the center of the Milky Way. Called Fermi bubble, it’s a type of structure still not well understood and a team led by Rongmon Bordoloi of MIT used the Hubble Space Telescope to change that measuring various characteristics of the gas inside the bubble.
An article published in the journal “Nature” describes the most detailed observations of incredibly fast winds that travel at speeds of up to 71,000 km/s, nearly a quarter of the speed of light, near a supermassive black hole. A team of researchers used NASA’s NuSTAR and ESA’s XMM-Newton space telescopes to observe this phenomenon at the center of the galaxy IRAS 13224-3809 recording very quick temperature changes.
An article published in “Astrophysical Journal” describes a research showing a link between a supermassive black hole and the galaxy that hosts it. A team of researchers used the ALMA radio telescope to study a galaxy in the heart of the Phoenix Cluster which has at its core a supermassive black hole that emits electromagnetic radiation jets that are stimulating the birth of new stars.
