What's the difference between an AGN and a Black Hole?

Показать описание

Hi Spacecats, I'm Dr Maggie Lieu and welcome to my channel, where you can find all things space, astronomy and physics! In this video I talk what exactly is an Active Galactic Nuclei (AGN) and how it differs from your day-to-day black hole.

Happy 2023. I’m definitely feeling like a dusty torus after new years drinks 😅🎉 🥂 cheers Maggie. Wishing you an awesome year….and beyond 🚀

Powerful stuff. Is it just radiation that is being emitted from the poles, not actual physical material? Is anything that the AGN "eats" ever seen again?

Petertronic

Is there any AGN detected fairly close to Earth and if so, how close it is to us? Happy New Year!

Nice video and nice channel! how we have a photo of sargitarius A*, if he isnt an AGN? and every AGN has relativistic jets?

Thanks for a great video. Do you think it would be possible for us to detect stellar mass black holes through their gravitational lensing?

Are there examples of AGN's interacting? Maybe orbiting each other or merging? What would that look like? 😁
