G359.87+0.18: An FR II Radio Galaxy 15 Arcminutes from Sgr A*. Implications for the Scattering Region in the Galactic Center

open access: yes, 1998
G359.87+0.18 is an enigmatic object located 15' from Sgr A*. It has been variously classified as an extragalactic source, Galactic jet source, and young supernova remnant.

The Galactic Center Lobe as an H ii Region

open access: yesThe Astrophysical Journal
The Galactic center lobe (GCL) is an object ∼1° across that is located north of the Galactic center. In the mid-infrared (MIR) the GCL appears as two 8.0 μ m filaments between which there is strong 24 μ m and radio continuum emission.

Indirect search for Dark Matter with H.E.S.S [PDF]

open access: yes, 2007
Observations of the Galactic center region with the H.E.S.S. telescopes have established the existence of a steady, extended source of gamma-ray emission coinciding with the position of the super massive black hole Sgr A*.

THE GALACTIC CENTER ENVIRONMENT [PDF]

open access: yesAnnual Review of Astronomy and Astrophysics, 1996
▪ Abstract  The central half kiloparsec region of our Galaxy harbors a variety of phenomena unique to the central environment. This review discusses the observed structure and activity of the interstellar medium in this region in terms of its inevitable inflow toward the center of the Galactic gravitational potential well.

Impact of Anisotropic Cosmic-Ray Transport on the Gamma-Ray Signatures in the Galactic Center

open access: yesThe Astrophysical Journal
The very high energy (VHE) emission of the central molecular zone (CMZ) is rarely modeled in 3D. Most approaches describe the morphology in 1D or simplify the diffusion to the isotropic case.

Search for dark matter by the Yakutsk array data

open access: yesEPJ Web of Conferences, 2017
We analyzed the Yakutsk Extensive Air Shower array data registered from 1974 to 2011. 14 particles were found that come directly from the Galactic Center to Earth without any deflection in the Galactic magnetic field.We suppose that these are particles ...

A Possible Common Physics Picture Reflected by the Gamma-Ray Emission of the Galactic Center

open access: yesThe Astrophysical Journal
Long-term observations of the Galactic center by Fermi and HESS have revealed a novel phenomenon: the high-energy gamma-ray spectrum from the gamma-ray source HESS J1745-290 exhibits a double power-law structure.

Galactic Center Observations with CTAO LST-1 [PDF]

open access: yesEPJ Web of Conferences
Very-high-energy gamma-ray observations of the central part of the Milky Way Galaxy allow for morphological study of cosmic-ray propagation around the supermassive black hole Sgr A*. An interpretation of the diffuse gamma-ray component, which spans a few
