I love your contributions to this forum. You mad...

If one assumes that, according to theory, every black hole also has an accretion disk... What theory is that? I think the overwhelming majority of black holes in the Universe have no accretion disk. This simulation shows the appearance of a black hole with an accretion disk. Simulations have also b...

On the topic of visualizations, Jean-Pierre Luminet is a French astrophysicist who made this image of a black hole 45 YEARS AGO! The first one ever apparently. Using maths, and a 1970’s computer… He’s still alive and still studying black holes today, he deserves a mention on this black hole week! (...

https://apod.nasa.gov/apod/calendar/S_240508.jpg Visualization: A Black Hole Accretion Disk Explanation: What would it look like to circle a black hole? If the black hole was surrounded by a swirling disk of glowing and accreting gas , then the great gravity of the black hole would deflect light em...

If the star directly impacts a massive black hole , then the star falls in completely -- and everything vanishes. More likely , though, the star goe...

MAUVE survey: Giant galactic explosion in NGC 4383 exposes galaxy pollution in action phys.org | 2024 April 21 TY4YA Jac Phys.org wrote about NGC 4383: Galaxy NGC 4383 evolving strangely. Gas is flowing from its core at a rate of over 200 km/s. This mysterious gas eruption has a unique cause: star ...

Is there even a definition of a "bar" based on something other than mere appearance? Is it simply dust/gas that is apparently concentrated more or less predominantly along a line through the galaxy core? Well. When I look at the galaxy in IR, it doesn't remind me much of a bar either. ......

I wonder why does SSDS fish have a collar (just like APOD fish does) and neither GLIMPSE nor SPITZER fish do? Good point. Well I think that since both work in the IR range, the view changes from dark dust clouds to bright warm gas clouds which appear practically equally bright in the front and back...

Still not much of a definitive bar in M61 at all compared to your other examples. And I'm not convinced of the "inner" bar in NGC 1365 either! "A bar is in the eye of the beholder" it seems. I just told you that I don't necessarily always trust Wikipedia, but now I'm going to qu...
