The MUSECuBES surveys on the circumgalactic medium
, 2019 The circumgalactic medium (CGM) is a dynamic, complex, multiphase, metal-enriched gas reservoir surrounding galaxies which harbors gas and metal masses comparable to those in galaxies themselves. Using a large quantity of spectral and imaging data obtained with MUSE & UVES on the VLT and ACS & COS on-board HST, we have started a major campaign ...

Modelling the cool gas clumps in the circumgalactic medium
Monthly Notices of the Royal Astronomical SocietyABSTRACT A major challenge in circumgalactic medium (CGM) studies is determining the three-dimensional (3D) properties from the observed projected observations. Here, we decompose the 3D gas density and spatial distribution of cool clouds by fitting a cool CGM model with the absorption observations, including the cool gas density, Ly ...

The MOSDEF-KCWI Survey: Spectral Properties of Lyα Halos around z ∼ 2 Star-forming Galaxies
The Astrophysical JournalWe present Keck Cosmic Web Imager integral field observations of extended Ly α emission in the circumgalactic medium of 27 typical star-forming galaxies at z ∼ 2, drawn from the Multi-Object Spectrometer for Infra-Red Exploration (MOSFIRE) Deep Evolution

The Astrophysical Journal LettersWe present a new analytical model for the attenuation to Epoch of Reionization (EoR) galaxies by proximate neutral hydrogen gas. Many galaxy spectra in the EoR taken by JWST have shown a flux deficit at wavelengths just redward of the Lyman break, and ...

FEASTS: Radial Distribution of H i Surface Densities Down to 0.01 M⊙ pc−2 of 35 Nearby Galaxies
The Astrophysical JournalWe present the H i surface density (Σ _H _i ) radial distributions based on total-power H i images obtained by FAST in the FEASTS program, for 35 galaxies with inclinations lower than 72°.

Dust Survival in Galactic Winds
The Astrophysical JournalWe present a suite of high-resolution numerical simulations to study the evolution and survival of dust in hot galactic winds. We implement a novel dust framework in the Cholla hydrodynamics code and use wind tunnel simulations of cool, dusty clouds to ...
