Small and massive compact galaxies are some of the hardest galaxies to find, but they could potentially reveal how galaxies evolved in the early universe.
Could the strange-looking irregular galaxies actually be remnants of the birth of galaxies? This paper demonstrates a method to find such galaxies.
Using the upcoming Gaia telescope to measure ripples in the Milky Way will allow us to detect the impact of clumps of dark matter on our host galaxy.
Galaxies have more than doubled in size since they first formed, but why?
A galaxy cluster in the act of forming reveals some interesting details about the lives of galaxies.
How can we find the distant galaxies that were responsible for bringing us out of the cosmic dark ages?
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 […]
To accurately model the universe, we need large surveys of its content and behavior. But how can we be sure that our surveys are a representative snapshot of the universe as a whole? In this post we tackle the problem of cosmic variance.
Does the existence of mysterious, ultra-luminous X-ray sources indicate that black holes may become more massive than previously thought?
