On the Origin of the 107 K Hot Emitting Gas in the Circumgalactic Medium of the Milky Way

The Astrophysical Journal
The presence of the ≈10 ^6 K gas in the circumgalactic medium of the Milky Way (MW) has been well established. However, the location and the origin of the newly discovered hot gas at “supervirial (SV)” temperatures of ≈10 ^7 K have been puzzling.

Orbital Torus Imaging: Acceleration, Density, and Dark Matter in the Galactic Disk Measured with Element Abundance Gradients

The Astrophysical Journal
Under the assumption of a simple and time-invariant gravitational potential, many Galactic dynamics techniques infer the milky Way’s mass and dark matter distributions from stellar kinematic observations.

The Extremely Metal-rich Knot of Stars at the Heart of the Galaxy

The Astrophysical Journal
We show with Gaia XP spectroscopy that extremely metal-rich (EMR) stars in the Milky Way ([M/H] _XP ≳ 0.5) are largely confined to a tight “knot” at the center of the Galaxy. This EMR knot is round in projection, has a fairly abrupt edge near R _GC,proj ∼

Radial Wave in the Galactic Disk: New Clues to Discriminate Different Perturbations

The Astrophysical Journal
Decoding the key dynamical processes that shape the Galactic disk structure is crucial for reconstructing the Milky Way’s evolution history. The second Gaia data release unveils a novel wave pattern in the L _Z −〈 V _R 〉 space, but its formation ...
