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 ...
“There have been lots of suggestions over time,” he said. “But this is the first work to really put all of the pieces of the puzzle together.” Reference: “The galaxy morphology–density relation in the EAGLE simulation” by Joel Pfeffer, Mitchell K Cavanagh, Kenji Bekki, Warrick J ...

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...

What is the Andromeda constellation? What gave the galaxy its distorted shape according to the Hubble Telescope? What are the stars in the constellation Orion? What is the history of the Cassiopeia constellation? Is Bootes a circumpolar constellation?

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...
