Can stellar clusters be host to multiple star formation events? The authors of today’s paper take a closer look…
What makes galaxies stop forming stars? Is gas removed entirely, or simply heated to prevent stars from forming? Today’s paper uses observations of carbon monoxide in post-starburst galaxies to try to answer this question.
Sometimes stellar remnants cannibalize other stars, emitting x-rays that can be detected in distant galaxies. Learn how making a careful tally of these gruesome events can reveal how stars are formed.
The authors of this paper pursued a mechanism which could possibly keep dead galaxies from forming new stars: mass ejected from AGB stars moving through the galaxy could heat the ambient gas.
Satellite galaxies orbiting a host galaxy seem to display highly anisotropic angular distributions.
Spherical cows have a long and storied history in physics, but does this type of crude approximation lead to realistic conclusions in the case of star formation? The combination of large- and small- scale simulations tests this idea.
How well do the current methods of measuring the star formation rate of galaxies match then known star formation rate in simulations?
The authors use a deep survey to locate rare galaxies which were among the earliest to form.
What are these Sauron-like double-horned profiles? Read this week’s undergrad research feature to find out!
How do we reproduce what happened previously in a galaxy-galaxy interaction when all we have is one snapshot in time?
