Observations of dust near the remains of a supernova in the center of our galaxy could have implications for dust production in the earliest galaxies.
This paper reports the results of a cosmological simulation, and how smooth accretion and mergers affect three important aspects of galaxy formation: stellar mass growth, size increase, and morphology changes.
How do you get a glimpse of dark matter? Stare really hard at the outskirts of galaxies and hope the matter isn’t totally dark.
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.
