Star-forming galaxies form stars at different rates. Could this be the model that reveals the underlying physics?
Today’s post looks at the investigation of a very small galaxy hosting a black hole that’s 15% of its total mass. This paper investigates whether this was once a much bigger galaxy, but has been robbed of its stars by a close call with another nearby galaxy.
Today’s paper makes predictions for the yet-to-be-observed dwarf galaxy population around Andromeda’s satellite galaxy, M33. It provides scientific justification for a future mission with WFIRST.
Could intermediate-mass black hole activity resolve the long-standing problems with dwarf galaxies in cosmological simulations?
This year, the Chandra X-ray Observatory is celebrating its 20-year legacy. Dr. Ryan Hickox of Dartmouth College will explain how the resulting discoveries have shaped our view of the high-energy universe in his plenary talk at #AAS233.
Observations from the MaNGA survey help to answer the question: What are the features of a galaxy that appears to have undergone recent gas accretion?
