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.
Stream in to today’s paper to understand how tearing apart dwarf galaxies can reveal the shape of the dark matter haloes of hungry galaxies.

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!
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.
How did our galaxies get so dusty so fast? Come with us today to do some early-epoch spring cleaning.
How does the gas in galaxies keep pace with star formation?
