The Halo Gas of Local Spiral Galaxies and the Link to Gaseous Satellites
Yong Zheng, Jingyao Zhu, Ben Wertz +2
Gaseous satellites orbiting massive host galaxies experience gas stripping and may contribute additional gas to the hosts' circumgalactic medium (CGM). We identify a sample of 21 l…
Revealing Cosmic Ecosystems with the Hubble Space Telescope in 2030s and Beyond
Sanchayeeta Borthakur, Tanmay Singh, David French +22
Ultraviolet spectroscopy with the Hubble Space Telescope (HST) provides the most direct and sensitive probe of the disk-circumgalactic medium (CGM) interface at radii of 20 kpc, wh…
The Metallicity Mapping of the Ionized Diffuse Gas at the Milky Way Disk-halo Interface
Bo-Eun Choi, Jessica K. Werk, Kirill Tchernyshyov +5
Metals in the diffuse, ionized gas at the boundary between the Milky Way's interstellar medium (ISM) and circumgalactic medium (CGM), known as the disk-halo interface (DHI), are va…
Figuring Out Gas & Galaxies in Enzo (FOGGIE). IX: The Angular Momentum Evolution of Milky Way-like Galaxies and their Circumgalactic Gas
Raymond C. Simons, Molly S. Peeples, Jason Tumlinson +10
We investigate the co-evolution of the angular momentum of Milky Way-like galaxies, their circumgalactic gas, and their dark matter halos using zoom-in simulations from the Figurin…
Identifying HI Emission and UV Absorber Associations Near the Magellanic Stream
Doyeon A. Kim, Yong Zheng, Mary E. Putman
We present a new technique to identify associations of HI emission in the Magellanic Stream (MS) and ultraviolet (UV) absorbers from 92 QSO sight lines near the MS. We quantify the…
The Nature of Ionized Gas in the Milky Way Galactic Fountain
Jessica K. Werk, Kate H. R. Rubin, Hannah V. Bish +6
We address the spatial scale, ionization structure, mass and metal content of gas at the Milky Way disk-halo interface detected as absorption in the foreground of seven closely-spa…
Probing Galactic Halos with Fast Radio Bursts
J. Xavier Prochaska, Yong Zheng
The precise localization (<1'') of multiple fast radio bursts (FRBs) to z>0.1 galaxies has confirmed that the dispersion measures (DMs) of these enigmatic sources afford a new oppo…
Revealing the Milky Way's Hidden Circumgalactic Medium with the Cosmic Origins Spectrograph Quasar Database for Galactic Absorption Lines
Y. Zheng, J. E. G. Peek, M. E. Putman +1
Every quasar (QSO) spectrum contains absorption-line signatures from the interstellar medium, disk-halo interface, and circumgalactic medium (CGM) of the Milky Way (MW). We analyze…
The Discovery and Origin of A Very-High Velocity Cloud Toward M33
Y. Zheng, J. K. Werk, J. E. G. Peek +1
We report the detection of a largely ionized very-high velocity cloud (VHVC; km/s) toward M33 with the Hubble Space Telescope/Cosmic Origin Spectrograph. The…
HST/COS Observations of Ionized Gas Accretion at the Disk-halo Interface of M33
Y. Zheng, J. E. G. Peek, J. K. Werk +1
We report the detection of accreting ionized gas at the disk-halo interface of the nearby galaxy M33. We analyze HST/COS absorption-line spectra of seven ultraviolet-bright stars e…
