Non-association of a celestial gamma ray source with the new Milky Way satellite galaxy [PDF]

, 1975
The newly discovered satellite galaxy located in the Milky Way galactic anti-center region is discussed along with the possibility that a nearby gamma ray source is associated with it.

Observational Constraints of Radial Migration in the Galactic Disk Driven by the Slowing Bar

The Astrophysical Journal Letters
Radial migration is an important dynamical effect that has reshaped the Galactic disk, but its origin has yet to be elucidated. In this work, we present evidence that resonant dragging by the corotation of a decelerating bar could be the main driver of ...

Multi-Messenger Signatures of the Milky Way Galaxy in Cosmic Rays, Neutrinos, and Gamma Rays

International audienceIn this talk, I reviewed recent measurements of the local Galactic cosmic ray flux up to the kneeregion, as well as the emission from the Milky Way galaxy in gamma-rays and neutrinos withinthe same energy range.

Multiwavelength Milky Way Educational Poster

, 2000
This poster depicts the Milky Way galaxy at radio, infrared, optical, x-ray, and gamma-ray wavelengths. Captions describe the Milky Way and what can be learned about the galaxy from measurements made in each segment of the electromagnetic spectrum. Note:

Andromeda galaxy vs Milky Way galaxy

Communications of the Byurakan Astrophysical Observatory
Some physical features of the Andromeda galaxy are compared with their counterparts in the Milky Way to demonstrate that the Andromeda galaxy has traversed a longer evolutionary path. One of the evolutionary dependents in galaxies is the metallicity factor. The metallicity radial gradient in galaxies can also be used for this purpose.

Chemodynamical simulations of the Milky Way Galaxy

, 2009
We simulate the chemodynamical evolution of the Milky Way Galaxy, including the nucleosynthesis yields of hypernovae and a new progenitor model for Type la Supernovae (SNe la). In our nucleosynthesis yields of core-collapse supernovae, we use light curve
