The Solar-Cycle Temporal Variation of the Solar Wind Charge Exchange X-ray Lines
Zhijie Qu, Dimitra Koutroumpa, Joel N. Bregman +2
Solar wind charge exchange (SWCX) is the primary contamination to soft X-ray emission lines from the Milky Way (MW) hot gas. We report a solar-cycle ( yr) temporal vari…
Absorption Line Search Through Three Local Group Dwarf Galaxy Halos
Zhijie Qu, Joel N. Bregman
Dwarf galaxies are missing nearly all of their baryons and metals from the stellar disk, presumed to be in a bound halo or expelled beyond the virial radius. The virial temperature…
Probing the He II re-Ionization ERa via Absorbing C IV Historical Yield (HIERACHY) I: A Strong Outflow from a z~4.7 Quasar
Xiaodi Yu, Jiang-Tao Li, Zhijie Qu +7
Outflows from super-massive black holes (SMBHs) play an important role in the co-evolution of themselves, their host galaxies, and the larger scale environments. Such outflows are…
An X-ray and SZ bright diffuse source toward M31: a Local Hot Bridge
Zhijie Qu, Rui Huang, Joel N. Bregman +1
We report a large-scale () X-ray and Sunyaev-Zeldovich (SZ)-bright diffuse enhancement toward M31, which might be a Local Hot Bridge connecting the Milky Way (MW…
The Warm Gas in the MW: A Kinematical Model
Zhijie Qu, Joel N. Bregman, Edmund Hodges-Kluck +2
We develop a kinematical model for the Milky Way Si IV-bearing gas to determine its density distribution and kinematics. This model is constrained by a column density line shape sa…
The warm Gaseous Disk and the Anisotropic Circumgalactic Medium of the Milky Way
Zhijie Qu, Joel N. Bregman
The warm () gas is an important gaseous component in the galaxy baryonic cycle. We built a 2-dimension disk-CGM model to study the warm gas distribution of the Milk…
