Pebbly Planets

Pebbly Planets

According to one theory of planet formation, the secret to forming massive planets is through itsy-bitsy, teeny-weeny pebbles of dust. In today’s astrobite, we explore what sort of planets these little pebbles could form.

Clearing up the Redshifts of Obscured AGNs

Clearing up the Redshifts of Obscured AGNs

The redshifts of active galactic nuclei (AGNs) can help us piece together the universe’s evolutionary timeline. Unfortunately, measuring these redshifts can be pretty tricky. In today’s astrobite, we look at a trick for estimating and constraining the redshifts of AGNs that are – ironically enough – partially obscured from our view.

The diffuse interstellar medium (ISM) isn’t as smooth as its name makes it sound. In today’s astrobite, we look at one mechanism for clumping up the diffuse ISM, and how that mechanism could affect molecular hydrogen formation.
