Star formation is enhanced when two galaxies interact or merge. But what is the orbital extent of enhanced star formation in interacting galaxies? At which projected separation of the two galaxies does it disappear?
What causes the giant radio and gamma-ray bubbles inflated from our galactic center? This paper provides another good argument for star formation as the culprit.
Relative velocity in the early Universe between regular matter (baryons) and dark matter enhances an otherwise hard-to-detect signal and makes it likely we can look back even farther into the past.
Hubble observations of a nearby galaxy show evidence for a universal initial mass function.
A team of astronomers working on the 3D-HST survey make use of the Hubble Space Telescope’s grism to observe star formation as a function of radius in a large sample of galaxies at intermediate redshift.
Boss & Keiser examine how magnetic fields with varying initial conditions affect star formation.
TITLE: Comparing the Ancient Star Formation Histories of the Magellanic Clouds AUTHORS: Daniel R. Weisz, Andrew E. Dolphin, Evan D. Skillman, Jon Holtzman, Julianne J. Dalcanton, Andrew A. Cole, Kyle Neary AUTHORS’ INSTITUTION: University of Washington The evolution of galaxies can be investigated in two ways: we can observe galaxies at farther distances to get a picture of [...]
Carretti and collaborators have found new evidence that the gigantic bubbles of emission emanating from the center of our Milky Way are the result of winds from supernova explosions, not jets from our supermassive black hole.
There is a long standing debate on whether the X-factor, the conversion factor between molecular hydrogen and carbon monoxide in molecular clouds, is constant in our Galaxy. This is a very important assumption we usually make when studying star formation! In this post, we explore state-of-the-art simulations by Narayanan & Hopkins that attempt to settle this debate.
