Using X-Rays to Reveal the Secrets of How Black Holes Shape Our Universe

- How do supermassive black holes shape the evolution of galaxies? What does an event horizon really look like? Why do black holes emit bursts of energy called ‘relativistic jets’?
In search of answers to these questions, astrophysicist Erin Kara explores black holes by carefully tracking the gas and plasma swirling near their event horizons. To reconstruct the immediate environment, Kara turns to the X-ray light given off by the accretion disk, measuring the timing of photons using a telescope mounted on the International Space Station. This technique - called reverberation mapping - works in a manner similar to how bats ‘see’ using sound echolocation, allowing researchers to infer the structure of the gas and plasma with remarkable resolution.

Its always nice when a researcher credits their grad students :)
It's always a good day when there's a new Quanta video
Always fun to learn new stuff regarding black holes.
Really love how you turned it into music in the end! Makes the topic understandable on so many levels.
Want to see more from her. Great presentation.
Agreed, she is an excellent communicator
An elegant approach to "imaging" accretion disks, elegantly told. Someone really needs to update the wikipedia NICER entry.
I'm currently watching an excellent NOVA PBS documentary on Black Holes. I'm at the part where they talk about the x-rays and jets and got really confused, so this was great to watch and helped me understand a lot more. Thanks, Dr. Kara & Quanta!
This is so cool!
Excellent video!
What's the cello track in the beginning called?
great science, great video, great presentation
When measuring time differences so close to a massive gravity field, how do you correct for time dilation? I guess the *exact* mass (aka the gravity forces) of the black hole is unknown and also the two measuring points probably have different gravity.
Great work. Looks like resolution is ~10 min or 0.8billion km. Sounds a lot, but accretion disk is itself of the order of ~1000 bn km!
hella sick!
Do you assume that the accretion disk is a uniform disk?
I like it even more how she tell the story
Trippy.
SAG Astar & the Milky way is a water fall, we are on the river's of time. While I think a black hole would be a Serene sink hole. The event Horizon. the very point where wheel meets track of a coal train on rail track's in a tunnel with the Waight of the World; I imagine the Sound heat & Waight of the very point between wheels & track. but then again. A continuous drip of water in the same tunnel can bend a metre of steel rail track. Crazy. Oh & that single drip. That sound & Echo. Is the same time it would take for two Black holes to collide. Only in a greater Waight heat & Radio wave's.
Awesome!!!🌟🌟💯💯
Nicer!
How did the largest black hole form❓ I mean how they can eat so much to grow❓ almost all galaxy’s center had a super massive black hole, but they can’t eat the entire galaxy ❗
I got distracted after they called the inner accretion disk "corona"😅
🤯
🙏🙏🙏🙏🙏
Black hole sounded like the Doppler Effect to me
They are similar.
Maybe black holes are plasmoids?

I usually don't make it more than a minute through vocal fry before giving up on the audio but I listened to her all the way through cause this was more interesting than it was hard on the ears.
Nobody is impressed by your bugbears; consider keeping your negativity to yourself.
sexist comment
I don't like creaky voices regardless who they come from. You made it about sexism. Not me.
@@OllyWood688 Studies have shown men complain about vocal fry overwhelmingly more often when it's a woman speaking. Aside from potential sexism (not necessarily accusing you), it's really rude to criticise the way someone speaks, just as it's really rude to criticise the way someone looks
@@Kyle-gw6qp I see your point, and I think this is just a cultural difference here in Germany, or maybe just my own bubble.
Temperature in Kelvin is not measured in degrees
The title is misleading in my opinion.
Slightly, but fairly. I mean, are you left disappointed?
Without a doubt
I don't think that's the case at all. They are talking about observing X-Ray emissions, and how they made techniques and methods to model the energy output.
The video is literally what the title says it is
@@israelsolano5347they changed it, originally it was something along the lines of “Using X-Rays to See INSIDE Black Holes”, which is definitely misleading
Last One....If you were in a room..With a normal window moving @ light speed forward..."The Window Is Too Big To Steer Through The Blurry Future"...."Create A Sensible Focused Time Gap"...So "Block Up The Window".."Make A PinHole"..And "Steer From The Upside Down Past 20/20 Hindsight Rear Wall Image"...→ > -|- < → You can "Steer" from a "Clear Rear Window Too"..Either Way..??.."Hindsight Is The Best Guide To The Future"..."The Rear Wall"..??.."Is The Only Wall That Will Make Sense"...Take Care...Bye..
amazing voice and face you have... Not gonna lie, would not click on the video without the too-promising title but I expect more from the scientific community.
turning it into music is a bit bullshitty simply to get media exposure isn't it....
As I understand it, for relativistic effects these tonal changes are a pretty cool way to make them accessible to our senses on a more direct intuitional level. Ofc it's gimmicky
I wish people stopped saying "close to the speed of light". Please stop, people.
Mmmm cartoons don’t prove anything.
fake news
Why?
@@bjornfeuerbacher5514 original title said it could see inside black holes
@@zwan1886 They corrected the title, so it's not "fake news" anymore.
no credit for the animation?
Smart women are great. I want to have Erin's babies.
