The interaction between the supersonic motion of the Large Magellanic Cloud (LMC) and the Circumgalactic Medium (CGM) is expected to result in a bow shock that leads the LMC's gase…
A Comprehensive Investigation of Metals in the Circumgalactic Medium of Nearby Dwarf Galaxies
Yong Zheng, Yakov Faerman, Benjamin D. Oppenheimer +7
Dwarf galaxies are found to have lost most of their metals via feedback processes; however, there still lacks consistent assessment on the retention rate of metals in their circumg…
Turbulence in Milky Way Star-Forming Regions Traced by Young Stars and Gas

It is surprising to find a fact for migration in the peak positions of synchrotron spectra energy distribution component during in the activity epochs of Mrk 421, accompanying with…
Figuring Out Gas & Galaxies In Enzo (FOGGIE). IV. The Stochasticity of Ram Pressure Stripping in Galactic Halos
Raymond C. Simons, Molly S. Peeples, Jason Tumlinson +9
We study ram pressure stripping in simulated Milky Way-like halos at z>=2 from the Figuring Out Gas & Galaxies In Enzo (FOGGIE) project. These simulations reach exquisite resolutio…
Figuring Out Gas & Galaxies in Enzo (FOGGIE). III. The Mocky Way: Investigating Biases in Observing the Milky Way's Circumgalactic Medium
Yong Zheng, Molly S. Peeples, Brian W. O'Shea +6
The circumgalactic medium (CGM) of the Milky Way is mostly obscured by nearby gas in position-velocity space because we reside inside the Galaxy. Substantial biases exist in most s…
Searching for AGN and Pulsar Candidates in 4FGL Unassociated Sources Using Machine Learning
Kerui Zhu, Shi-Ju Kang, Yong-Gang Zheng
In the fourth \emph{Fermi} Large Area Telescope source catalog (4FGL), 5064 -ray sources are reported, including 3207 active galactic nuclei (AGNs), 239 pulsars, 1336 unassociat…
Direct Detection of Black Hole-Driven Turbulence in the Centers of Galaxy Clusters
Yuan Li, Marie-Lou Gendron-Marsolais, Irina Zhuravleva +16
Supermassive black holes (SMBHs) are thought to provide energy that prevents catastrophic cooling in the centers of massive galaxies and galaxy clusters. However, it remains unclea…
