Does this disk make my collapse look brighter?
What happens when a neutron star collapses into a black hole? What kind of signal could we expect to see? These theorists have some ideas…
Sgr A* Snacks Between Meals, Too
Small daily flares are observed from the black hole in the center of our galaxy. The authors of this paper propose the flares are due to Sgr A* frequently snacking on asteroids!
Mealtime for Sgr A*
Remember that tidal disruption event we talked about earlier this year, where a star got just a little too close to a quiescent black hole? Well, here’s our chance to witness something similar, happening in the center of our very own galaxy!
Shadow of a Black Hole
Messier 87 (M87) is a giant elliptical galaxy that is best known for its spectacular, 5000-ly-long jet. In this paper, the authors develop models of M87 based on general relativistic numerical simulations and make predictions for the future direct observations of the black hole event horizon that may be possible.
