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'.
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 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." #Astronomy#Cosmology#BlackHoles#NASA
It’s now thought that they could illuminate fundamental questions in #physics, settle questions about #Einstein’s theories, & even help explain the #universe.
…In recent yrs, the amt of data that scientists have discovered about black holes has grown exponentially.
#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.
@IRAP#Seminar] this Thursday at 11am. Benjamin Crinquant, a young researcher at IRAP, will present the progress we have made in our knowledge of #BlackHoles: from the observations carried out by the #GRAVITY and #EventHorizonTelescope collaborations to the most recent models of the #magnetospheres and #coronae of black holes.
For those of you speaking French (I don't) - what I was told to be a really nice documentary about #BlackHoles featuring some of my amazing colleagues from #ESA, including my former PhD candidate Dr. Camille Diez:

Angela Borchers Pascual is a PhD student in the @maxplanckgesellschaft independent research group “Binary Merger Observations and Numerical Relativity”. She is working on understanding the imprint of gravitational kicks in the gravitational-wave signals emitted by merging black hole binaries.
Eight years ago, lecture theater 222 in the Kelvin Building, University of Glasgow was full to bursting with people waiting for an announcement by @LIGO about 'the event' ...
Dr. Elisa Maggio is a postdoctoral researcher in the “Astrophysical and Cosmological Relativity” department. She works on tests of gravity in the strong field regime with gravitational-wave observations and on tests of the nature of black holes.
From Live Science: Scientists using the eROSITA X-ray telescope have released a trove of data that reveals more than 900,000 objects in space, including 700,000 supermassive black holes and other "exotic" objects. https://flip.it/Y9IMb1 #Science#Space#BlackHoles#SpaceExploration
