The role of an excited black hole in the death of an exotic ‘jellyfish’ galaxy will be presented today (3 July) by Callum Bellhouse of the University of Birmingham at the RAS National Astronomy Meeting in Lancaster. The supermassive black hole at the centre of jellyfish galaxy JO201 is stripping away gas and throwing it out into space, accelerating suppression of star…

Our galaxy’s central black hole is oddly quiet – now we may know why
The supermassive black hole at the Milky Way’s centre is relatively calm and peaceful, which may be because magnetic fields keep gas and dust just out of reach Source: https://www.newscientist.com/article/2206685-our-galaxys-central-black-hole-is-oddly-quiet-now-we-may-know-why/?utm_campaign=RSS%7CNSNS&utm_source=NSNS&utm_medium=RSS&utm_content=home…
Is This Invisible Magnetic Field Smothering Our Nearest Supermassive Black Hole?

Hubble observes tiny galaxy with big heart
Nestled within this field of bright foreground stars lies ESO 495-21, a tiny galaxy with a big heart. ESO 495-21 may be just 3000 light-years across, but that is not stopping the galaxy from furiously forming huge numbers of stars. It may also host a supermassive black hole; this is unusual for a galaxy of its size, and may provide intriguing…
ALMA spies a cool gas ring around our Milky Way’s central black hole
New observations by the ALMA telescope in Chile have revealed a never-before-seen disk of cool, interstellar gas wrapped around Sagittarius A*, the giant black hole at the center of our galaxy. Source: https://earthsky.org/space/cool-gas-ring-milky-way-central-black-hole…
Detection of powerful winds driven by a supermassive black hole from La Palma
The supermassive black holes in the centres of many galaxies seem to have a major influence on their evolution. This happens during a phase in which the black hole is consuming the material of the galaxy in which it resides at a very high rate, growing in mass as it does so. During this phase, the galaxy has an active galactic…
Cool, nebulous ring around Milky Way’s supermassive black hole
New ALMA observations reveal a never-before-seen disk of cool, interstellar gas wrapped around the supermassive black hole at the center of the Milky Way. This nebulous disk gives astronomers new insights into the workings of accretion: the siphoning of material onto the surface of a black hole. The results are published in the journal Nature.
