The black hole that ate its own star. This is some neat science!

A new paper reports that VFTS 243, a massive binary system featuring an O-class star and a 10 solar-mass black hole companion, might have formed through the 'complete collapse scenario'.

New research on black holes suggests these enigmatic objects of the universe could actually be entirely different celestial entities known as gravastars. Live Science has more: https://flip.it/30YfFs

Just stumbled over this lovely article about my friend Erin and her work to decipher the timing of #BlackHoles!

(May possibly give some background context on our recent paper on Cyg X-1 that I posted about yesterday and that Erin was also part of the team for 😊)

#Papertime today: "Long term variability of Cygnus X-1. VIII. A spectral-timing look at low energies with NICER" by Koenig et al.

http://arxiv.org/abs/2405.07754

What did we do & why is this interesting? Deep technical dive ahead!

We learn about accreting #BlackHoles studying their spectra & short-term (~millisecond) variability, called timing. However, individually, both approaches leave us with a lot of puzzles - so we try to combine them in spectral-timing.

Nasa shows what it's like inside a black hole

"Nasa has released footage simulating what it's like being sucked into a black hole, a region of space with such strong gravity not even light can escape."

#ICYMI: A recent #EHT image reveals strong magnetic fields spiraling from Sagittarius A*, the supermassive black hole at our galaxy’s center. These fields resemble those around the M87 galaxy’s black hole, suggesting commonality among black holes. A hidden jet in Sagittarius A* is also hinted at.

What Is Quantum Teleportation?
Teleporting people through space is still science fiction.

But quantum teleportation is dramatically different and entirely real. In this episode, Janna Levin interviews the theoretical physicist John Preskill about teleporting bits and the promise of quantum technology.
