Correlation-Dropping Into the Reionization Era
We still don’t know very much about the mysterious epoch of reionization. In today’s bite, learn about a new way to estimate when reionization started from a correlation drop!
A Merger is Not a Meal: How to Feed Supermassive Black Holes in the Early Universe
How did supermassive black holes in the early universe get so massive? Today’s bite uses simulations to investigate whether galaxy mergers can help beef up black holes.

[Guest] The Walking Dead: Warm Worlds Around Dead Stars
For today’s bite guest author, Savaria Parrish, explores the prospects for habitability on planets around a class of stellar remnants known as white dwarfs!
The Universe’s Most Wanted Black Holes Finally Have an Alibi
GW231123 defies our best models of stellar collapse, hosting two black holes that shouldn’t exist. A new paper proposes a radical solution: these monsters may have been born in the early universe as primordial black holes, quietly feeding for billions of years until they became the record-breakers we detected today.
Where Did All This Dust Come From?
How did our galaxies get so dusty so fast? Come with us today to do some early-epoch spring cleaning.
