Using new ultraviolet (UV) spectra of five background quasars from the Cosmic Origins Spectrograph on the Hubble Space Telescope, we analyze the low-latitude (|b|=20-30 degree) regions of the Fermi Bubbles, the giant gamma-ray emitting lobes at the Galactic Center. We combine these data with previous UV and atomic hydrogen (HI) datasets to build a comprehensive picture of the kinematics and metal column densities of the cool outflowing clouds entrained in the Fermi Bubbles. We find that the… 
CO Emission Delineating the Interface between the Milky Way Nuclear Wind Cavity and the Gaseous Disk
Based on the MWISP survey, we study high-z CO emission toward the tangent points, in which the distances of the molecular clouds (MCs) are well determined. In the region of l = 12°–26° and ∣b∣ ≲
Fermi and eROSITA bubbles as relics of the past activity of the Galaxy’s central black hole
The newly launched X-ray satellite, eRosita, has recently revealed two gigantic bubbles extending to ∼ 80◦ above and below the Galactic center. The morphology of these “eRosita bubbles” bears a
North Polar Spur/Loop I: gigantic outskirt of the Northern Fermi bubble or nearby hot gas cavity blown by supernovae?
Radio continuum, microwave and gamma-ray images of the Milky Way reveal a conspicuous, looplike structure that fills almost half of the northern Galactic hemisphere, called Loop I. The interior of
The Structure of Multiphase Galactic Winds
We present a novel analytic framework to model the steady-state structure of multiphase galactic winds comprised of a hot, volume-filling component and a cold, clumpy component. We first derive
Chandra large-scale mapping of the Galactic Centre: probing high-energy structures around the central molecular zone
Recent observations have revealed interstellar features that apparently connect energetic activity in the central region of our Galaxy to its halo. The nature of these features, however, remains
Molecular Gas within the Milky Way's Nuclear Wind
We report the first direct detection of molecular hydrogen associated with the Galactic nuclear wind. The Far-Ultraviolet Spectroscopic Explorer spectrum of LS 4825, a B1 Ib–II star at l, b =
An Analysis of the North Polar Spur Using HaloSat

The Impact of Cosmic Rays on Thermal Instability in the Circumgalactic Medium
Large reservoirs of cold (~ 10^4 K) gas exist out to and beyond the virial radius in the circumgalactic medium (CGM) of all types of galaxies. Photoionization modeling suggests that cold CGM gas has


Improvements to the COS FUV G130M and G160M Wavelength Solutions at Lifetime Position 1
The wavelength dispersion coefficients and zero points of the COS FUV G130M and G160M gratings at each lifetime position (LP1, LP2, LP3, LP4) have been re-derived. In this document we present the
Multi-Cycle Analysis of the STIS Dispersion Solutions
The dispersion solutions for the most used STIS CCD and MAMA configurations are monitored on a yearly basis using two specific calibration programs. In this report, we present the analysis performed
Cooling functions for low-density astrophysical plasmas
The cooling functions for a plasma slab are investigated under equilibrium and nonequilibrium conditions, over a range of 10 4 -10 8.5 K and for a range of abundances. Radiative transfer and diffuse
The formation and physical origin of highly ionized cooling gas
We present a simple model that explains the origin of warm diffuse gas seen primarily as highly ionized absorption line systems in the spectra of background sources. We predict the observed column
Accurate galactic 21-cm H I measurements with the NRAO Green Bank Telescope
Aims. We devise a data reduction and calibration system for producing highly-accurate 21-cm H i spectra from the Green Bank Telescope (GBT) of the NRAO. Methods. A theoretical analysis of the all-sky
Cool outflows in galaxies and their implications
Neutral-atomic and molecular outflows are a common occurrence in galaxies, near and far. They operate over the full extent of their galaxy hosts, from the innermost regions of galactic nuclei to the
Observation of Acceleration of H i Clouds within the Fermi Bubbles
The ~200 HI clouds observed to be entrained in the Fermi Bubble wind show a trend of increasing maximum |VLSR| with Galactic latitude. We analyze previous observations and present new data from the
The Large-scale Ionization Cones in the Galaxy
There is compelling evidence for a highly energetic Seyfert explosion (10^{56-57} erg) that occurred in the Galactic Centre a few million years ago. The clearest indications are the x-ray/gamma-ray
Blowing in the Milky Way wind: neutral hydrogen clouds tracing the Galactic nuclear outflow
We present the results of a new sensitive survey of neutral hydrogen above and below the Galactic Center with the Green Bank Telescope. The observations extend up to Galactic latitude | b | 140$ deg.
Probing the Southern Fermi Bubble in Ultraviolet Absorption Using Distant AGNs
The Fermi Bubbles are two giant gamma-ray emitting lobes extending 55$^{\circ}$ above and below the Galactic Center. While the Northern Bubble has been extensively studied in ultraviolet (UV)
