The Warm Gas in the MW: the Kinematical Model of C IV and its Connection with Si IV
Zhijie Qu, Ryan Lindley, Joel N. Bregman
We compose a 265-sight line MW C IV line shape sample using the HST/COS archive, which is complementary to the existing Si IV samples. C IV has a higher ionization potential ($47 -…
Hot Extended Galaxy Halos Around Local L* Galaxies From Sunyaev-Zeldovich Measurements
Joel N. Bregman, Edmund Hodges-Kluck, Zhijie Qu +3
Most of the baryons in L* galaxies are unaccounted for and are predicted to lie in hot gaseous halos (T ~ 3E6 K) that may extend beyond R200. A hot gaseous halo will produce a ther…
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…
The Resolved Sunyaev--Zel'dovich Profiles of Nearby Galaxy Groups
C. T. Pratt, Z. Qu, J. N. Bregman
Much of the baryons in galaxy groups are thought to have been driven out to large distances () by feedback, but there are few constraining observations of this ex…
