Whippet TDE: Black Hole Eruption of 400 Billion Suns Energy
What is a Tidal Disruption Event (TDE)? A Tidal Disruption Event, or TDE, occurs when a star ventures too close to a supermassive black hole. The black hole’s immense gravity tears the star apart, scattering stellar debris that heats up and emits intense radiation. These cosmic cataclysms offer a rare glimpse into otherwise quiescent black…

Supermassive Black Holes Feed Selectively During Galaxy Mergers
Introduction: A Surprising Appetite Black holes are famed for their voracious appetites, devouring matter that strays too close. But new observations from the Atacama Large Millimeter/submillimeter Array (ALMA) reveal a more nuanced behavior, even for the universe’s most massive beasts. During galaxy mergers, supermassive black holes (SMBHs) appear to eat selectively, preferentially accreting certain streams…
