Probing the Hot Gaseous Halos of Milky Way-like Galaxies in the TNG50 simulation
Zhijie Zhang, Xiaoxia Zhang, Taotao Fang +9
The origin and structure of the hot (K) gaseous halo around Milky Way (MW)-mass galaxies provide a critical test for galaxy formation models. We perform a comprehensi…
A Systematic Search for Gaseous Debris Disks in DESI Early Data Release White Dwarfs
Ziying Ma, Xiaoxia Zhang, Taotao Fang +5
Detecting gaseous debris disks around white dwarfs offers a unique window into the ultimate fate of planetary systems and the composition of accreted planetary material. Here we pr…
Tracing the Origins of Hot Halo Gas in Milky Way-Type Galaxies with SMUGGLE
Zhijie Zhang, Xiaoxia Zhang, Hui Li +8
Current galaxy formation models predict the existence of X-ray-emitting gaseous halos around Milky Way (MW)-type galaxies. To investigate properties of this coronal gas in MW-like…
The ALMA Survey of 70 m Dark High-mass Clumps in Early Stages (ASHES). XII. Unanchored Forked Stream in the Propagating Path of a Protostellar Outflow
Shuting Lin, Siyi Feng, Patricio Sanhueza +14
Outflows are key indicators of ongoing star formation. We report the discovery of an unanchored forked stream within the propagating path of an extremely young protostellar outflow…
Distance estimation of the high-velocity cloud Anti-Center Shell
Yu-Ting Wang, Chao Liu, Zhi-Yu Zhang
High-velocity clouds (HVCs) are interstellar gas clouds whose velocities are incompatible with Galactic rotation. Since the first discovery of HVCs in 1963, their origins have been…
