An international scientific team has revealed for the first time the #magneticfieldtransport processes in the accretion flow of a #blackhole and the formation of a "#MAD"—a #magneticallyarresteddisk—in the vicinity of a black hole.

Pour déterminer quelle serait la plus grande vitesse de recul atteinte par un trou noir issu d’une fusion, deux physiciens ont effectué un grand nombre de simulations numériques en faisant varier les différents paramètres physiques en jeu. Ils trouvent une valeur maximale de vitesse qui défie l’entendement… Ils publient leur étude dans Physical Review Letters.

For a half century, #mathematicians have tried to define the exact circumstances under which a #blackhole is destined to exist. A new #proof shows how a #cube can help answer the question.

Which do you like better, black holes or donuts? We ask because black holes and donuts are often detected with ring-shaped matter. Gas and dust for black holes, and sugar-covered cake for donuts. Dig in with #NASAWebb: https://webbtelescope.pub/3rkvBzq

Hubble announced one of its most significant discoveries #OTD in 1994: decisively confirming the existence of supermassive black holes, as predicted by Albert Einstein. Discover more about the breakthrough on our timeline: https://bit.ly/3MWiIIa Credit: NASA, STScI.

Astronomers using Hubble say they’ve found some of the best evidence yet for the presence of a rare class of intermediate-sized black hole. It may be lurking in the heart of the closest globular star cluster to Earth: https://bit.ly/3MNQGxK

Look closely at this spiral galaxy to spot a circled, blue dot. It marks the location of what could be a black hole weighing 20,000 Suns. Its color is the result of light from both an accretion disk and a surrounding cluster of young stars: https://bit.ly/3A9mFSb #BlackHoleWeek #BlackHole #astronomy #space

Sabine Thater reminded us -- in a nice colloquium talk at @AIP_Potsdam -- that already John Michell thought about Black Holes on Nov 27, 1783. #BlackHole
She also briefly discussed her newest paper on SMBH estimates https://arxiv.org/abs/2304.13310. (Yay, with #musevlt data!)
It looks like a #blackhole and bends light like a black hole, but it could actually be a new type of #star.
