Diffuse HI emission in the circumgalactic medium of NGC891 and NGC4565 - III: azimuthal profiles
Mary Rickel, Sanskriti Das, Nickolas M. Pingel +4
Diffuse HI emission in the circumgalactic medium (CGM) of NGC891 and NGC4565 has been previously shown to trace an inflow along minor axes pointings and to co-rotate with the HI di…
The GOLIATH Survey: OVI Absorption Reveals CGM Evolution through the Starburst-to-Quiescent Transition in Massive Galaxies
Derick Flores, Rongmon Bordoloi, Jason Tumlinson +12
We present the GOLIATH survey (Galaxies, Outflows, and the Lifecycle of Immense, Active, Transforming Halos), a study of the multiphase circumgalactic medium (CGM) of massive ($\la…
The Merging Galaxy Cluster Environment Affects the Morphology of Radio-AGN
Mary Rickel, Emily Moravec, Yjan A. Gordon +4
It has previously been found that the galaxy cluster environment can affect the fueling and evolution of Active Galactic Nuclei (AGN). This work examines the effect of the merging…
Detection of diffuse HI emission in the circumgalactic medium of NGC891 and NGC4565 -- II
Sanskriti Das, Mary Rickel, Adam Leroy +6
We probe the neutral circumgalactic medium (CGM) along the major axes of NGC891 and NGC4565 in 21-cm emission out to kpc using the Green Bank Telescope (GBT), extendin…
