Connecting galaxy properties to their star-formation histories

Connecting galaxy properties to their star-formation histories

by John Weaver | Feb 1, 2019 | Daily Paper Summaries

Star-forming galaxies form stars at different rates. Could this be the model that reveals the underlying physics?

Small, but Mighty! A galaxy robbed of its stars but contains a supermassive secret.

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.

Traits of Accreting Galaxies

Traits of Accreting Galaxies

by Caitlin Doughty | Dec 18, 2018 | Daily Paper Summaries

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?
