Evolution of the M∗–MBH Relation from z ∼ 6 to the Present Epoch

The Astrophysical Journal
The ratio between the stellar mass of a galaxy, M _* , and that of its central supermassive black hole (SMBH), M _• , the “Magorrian” relationship, traces their coevolution.

Velocity Structure Correlations between the Nebular, Molecular, and Atmospheric Gases in the Cores of Four Cool Core Clusters

The Astrophysical Journal
We investigate the velocity structure of nebular gas in the central galaxies of four clusters: A1835, PKS 0745−191, A262, and RXJ0820.9+0752, using data from the Keck Cosmic Web Imager. Velocity structure functions (VSFs) of the [O ii ] emission line are

The Low-mass and Structured Stellar Halo of M83 Argues Against a Merger Origin for Its Starburst and Extended Neutral Hydrogen Disk

The Astrophysical Journal
A merger origin has been suggested for M83’s massive, metal-rich extended H i disk and nuclear starburst. We observe M83’s stellar halo to test this idea.
