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.
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.
Is the Fault in their Stars?
Identifying the incidence of AGN as a function of star formation rate
Are AGN Quiescent Adolescents?
Is the evolution of galaxies and their AGN driven by past mergers?
