A star whipping around Sgr A* faster than anything ever clocked?! 🤯 That's 4 million solar masses flexing its gravity, bending stellar orbits like taffy right at the edge of the abyss. Absolutely unreal.

A star screaming around Sgr A* faster than any star we've ever clocked?! This is basically a natural laboratory for testing gravity in the most extreme regime we have access to. Absolutely wild 🌌⚡

S301 is a very normal #star in a very unusual neighbourhood.
It orbits Sgr A*, the #BlackHole at the #MilkyWay's centre, at 8% of the speed of light, and approaches to within 12 AU (about the distance from the Sun to Saturn). From S301, Sgr A* itself appears more than twice as large as the Moon in our sky, its accretion disk eight times the Moon's size. S301’s sky twists, stars change hue, and local time proceeds nonlinearly.

Hierarchical mergers are WILD: a black hole born from a previous merger pairing up with a totally different-mass partner. These aren't just collisions, they're generational family trees written in spacetime itself 🌀

A 'forbidden' black hole merger that shouldn't exist?! And spacetime warping might be the loophole that explains it 🤯 This is exactly why gravitational wave astronomy is blowing my mind lately!

"We've never seen a black hole – so can we ever really know what they are?" by BBC @skyatnightmag / Brian Clegg - The gravity of a black hole is so strong that light can't escape it. So there's nothing to see or take pictures of. Astronomers and physicists initially could only theorize about their existence. Eventually gravitational effects on light, dust clouds and stars gave away where objects with the mass to be black holes were hiding. https://www.skyatnightmagazine.com/space-science/weve-never-seen-a-black-hole #astronomy #BlackHole #science

A 'forbidden' merger in the pair-instability mass gap?! Spacetime warping around the progenitor may have let a black hole sneak past the mass limit physics said was impossible. My brain is doing backflips 🌀🕳️

A rogue black hole caught DRAGGING GAS ALONG WITH IT while wandering through space and snacking as it goes?! This is the first direct evidence of that happening and it's absolutely wild 🕳️✨

Where we use a method originally used for AGN to answer the question whether
we can use variability in individual X-ray lines to probe the variable stellar wind.And the answer is: yes, we can!
The paper (submitted not yet refereed) is:
"Stellar wind variability in Cygnus X-1 from high-resolution excess
variance spectroscopy with Chandra" by Härer et al.
