Evidence for a Universal IMF from a Dwarf Galaxy

Hubble observations of a nearby galaxy show evidence for a universal initial mass function.

How to count stars you can’t see: the stellar IMF in distant galaxies

Van Dokkum & Conroy examane the variation of the stellar initial mass function by observing the integrated light from early-type galaxies.

Mind the (Black Hole Mass) Gap

You might think that stars with an approximately continuous distribution of masses would lead to remnants with an approximately continuous distribution masses. But you’d be wrong.

How did the universe get so dusty?

I just vacuumed my apartment and asked the question, ‘how does so much dust accumulate in one week?’ These authors ask a more scientifically interesting question: how can galaxies accumulate more than 100 million solar masses of dust in just a few hundred million years?
