Building Planets Around a Black Hole
We all know planets form around stars, can planet formation occur around something much more exotic?
Dwarf Galaxies without Dark Matter
Today’s paper looks at observations of 19 low mass galaxies which appear to contain no dark matter, potentially challenging our overall understanding of galaxy formation.
Hide and Seek with Satellite Galaxies
What happens to satellite galaxies when stellar radiation is added to simulations?
Galaxy collisions and star-formation: a surprising causal examination
The longstanding role of galaxy mergers as drivers of star-formation is brought into question
With Age Comes Wisdom
By determining the precise ages of stars in our galaxy, today’s Astrobite focuses on piecing together a detailed history of our own Milky Way.
Explaining Ancient Stellar Populations
Why do some dwarf galaxies exhibit such old stellar populations? Perhaps simulations of reionization including radiative transfer can help to explain this peculiar trait.
