The galaxy M82 is host to an extended multiphase wind driven by star formation. Today’s paper attempts to use JWST observations of dust in the wind to understand the structure of its cooler gas.
Cosmic rays, born from powerful events like exploding stars, are a key but elusive part of a galaxy’s interstellar medium. Today’s paper combines gamma-ray, X-ray, infrared, and radio observations of M82 to untangle how cosmic rays and magnetic fields shape its energetic core.
Today’s undergraduate research post is all about a search for dark matter in the starburst galaxy M82!
The recent discovery of a radio transient in the nucleus of the galaxy M82 has left scientists guessing as to what it might be. In this paper the authors examine the possibility that it’s a microquasar just like SS433 — but located outside of our galaxy!
