Sources and Radiations of the Fermi Bubbles

Universe
Two enigmatic gamma-ray features in the galactic central region, known as Fermi Bubbles (FBs), were found from Fermi-LAT data. An energy release, (e.g., by tidal disruption events in the Galactic Center, GC), generates a cavity with a shock that expands ...

Jet from the Milky Way center: the galactic center lobe

, 1986
The radio lobe in the galactic center found through 10-GHz continuum observations is likely to be a cylindrical jet emerging from the nuclear disk of the Milky Way Galaxy.

The distance to the galactic center [PDF]

, 2022
Methods used to determine the distance (R₀) to the galactic center are described and recent results are presented. These suggest that R₀≃7 Kpc.

A Possible Path to Mass Ratio and Spin–Orbit Misalignment Correlation: Mergers of Binary Black Holes in Nuclear Star Clusters

Universe
Despite a decade’s worth of gravitational wave observations, the origin of the binary black hole (BBH) mergers detected by the LIGO–Virgo–KAGRA (LVK) collaboration remains an open question.

Improved Galactic diffuse emission model strengthens the case for a Millisecond Pulsar explanation of the Fermi GeV excess

SciPost Physics Proceedings, 2023
After more than a decade since its discovery, the Galactic center gamma-ray excess - discovered with the Fermi Large Area Telescope - remains puzzling. While the spectrum of the signal can be explained by either dark matter or an unresolved population of

The Galactic Center in Color: Measuring Extinction with High-proper-motion Stars

The Astronomical Journal
The Milky Way’s central parsec is a highly extinguished region with a population of high-proper-motion stars. We have tracked 145 stars for ∼10 yr at wavelengths between 1 and 4 μ m to analyze extinction effects in color–magnitude space. Approximately 30%

Neurochemical Endpoints to Inform Early‐Stage Trials of Spinocerebellar Ataxia 2 and 3 in a Multisite Setting

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neurochemical levels measured by brain MR spectroscopy (MRS) have been proposed as endpoints for clinical trials in early‐stage spinocerebellar ataxia (SCA) trials. We tested their trial‐readiness by quantifying neurochemicals in three affected brain regions in early‐stage cohorts of SCA2 and SCA3, examining their reproducibility in ...

Constraining the Stellar Mass Function in the Galactic Center via Mass Loss from Stellar Collisions

Advances in Astronomy, 2011
The dense concentration of stars and high-velocity dispersions in the Galactic center imply that stellar collisions frequently occur. Stellar collisions could therefore result in significant mass loss rates.
