Dwarfs from ELVES: The structure of dwarf satellite galaxies
How does the structure of the smallest galaxies vary with different environments? Today’s authors use the ELVES survey to investigate!
Hunting for stellar splashback: defining the size of a galaxy cluster
How big is a galaxy cluster? Today’s authors use the remnants of destroyed galaxies to define the edge of galaxy clusters.
Spotting Spots on Other Stars
What does the surface of a star look like? Today’s authors observe ζ And using long-baseline interferometry to find out!
Glimpsing Dark Objects with Gaia
Today’s authors work out a full orbital solution for a binary microlensing system, indicating the method’s potential to probe the mass distribution of dark objects.
Stuck in the Middle: A New Gamma-Ray Burst Defies the Norm
Even for stellar explosions, this gamma-ray burst is a weird one!
Taking better astronomical images, with machine learning!
Too many cool science projects, not enough telescope time. Can machine learning help solve this problem?
