So… Are Black Holes Dark Energy?
In today’s bite, we investigate a controversial paper from two years ago, tracing its origins and attempting to finally answer the question: are black holes dark energy?
A Light in the Dark: Looking for Bright Black Holes as Dark Matter
If extremely low-mass primordial black holes are lurking in our galaxy, they should glow white hot with Hawking radiation. Today’s authors explore whether we can use this fact to tease out their presence.
Rapid Microlensing Classification: A Lonely SOBH Story
Today’s paper explores how we can use simulations of stellar populations to rapidly estimate the identity of the lensing object in a microlensing event.
That’s No Moon! The Search for Black Hole Asteroids, Stars, and Planets
If primordial black holes exist, one place we might find them is in binary systems with other objects like planets or asteroids. Today’s paper explores how common these systems might be and the various ways we might go about finding them.
Black Hole, Why Don’t You Come Over? White Dwarf Supernova!
The origin of dim supernovae known as Ca-rich transients is still not well-understood. Could it be that these rare events are set off by an encounter between a white dwarf and a primordial black hole?
