How does habitability vary on a galactic scale?
Prof. Charlie Conroy’s research spans from nearby stars to galaxies far, far away. Read more about his exciting research and career before his keynote at #AAS231!
In the study of structure formation in the universe, the ‘missing satellite galaxies’ problem is said to be almost solved. Is today’s paper the final nail in the coffin?
We understand cosmology by building models that we can trace back through time, but nothing about these models limits them to the past. As the universe expands, faster and faster pushed by dark energy, when does that acceleration outstrip gravity? And when do the last stars form?
There are nearly 10,000 galaxies in this image, with a staggering variety of shapes, colors, sizes, and ages. But buried beneath that variety, we can find patterns in how galaxies morph and evolve over time. Today’s astrobite explores one such set of links in the giant chains of galaxy evolution.
Today’s paper uses gravitational lensing to find a dusty starburst galaxy so far away that it existed when the universe was less than a billion years old.
