An almost head-on collision as the origin of two off-centre rings in the Andromeda galaxy The unusual morphology of the Andromeda galaxy (Messier 31, the closest spiral galaxy to the Milky Way) has long been an enigma. Although regarded for deca... DL Block,F Bournaud,F Combes,... -...
Generally, we do not find a faint thick disk of M 32. However, the comet-like shape on the periphery of M 32, especially as a formation with an increased red color index, provokes involuntarily the impression that the satellite M 32 overtakes the Andromeda galaxy. The redshifts show that...
A computer simulation of what the gas and stars in a galaxy cluster look like, highlighting how clusters of galaxies are embedded in cosmic web of filaments. In the color images, the intensity and color of the image represent the density and temperature of the gas. These figures show successi...
It sounds simple, but measuring a galaxy's true 3D shape is a tricky problem that astronomers first tried to solve 90 years ago. "This is the first time we've been able to reliably measure how a galaxy's shape depends on any of its other properties - in this case, its rotation speed...

The intensity and morphology of this signal depends on the properties of the interstellar medium through which the e± propagate. Using observations of the Andromeda Galaxy (M31) to construct a model of the gas, magnetic fields, and starlight, we set constraints on dark matter annihilation to ...
