Star formation is enhanced when two galaxies interact or merge. But what is the orbital extent of enhanced star formation in interacting galaxies? At which projected separation of the two galaxies does it disappear?
The central question of this Letter is how and when the Milky Way assembled its stellar mass. This issue is addressed by tracing the formation history of spiral galaxies which closely resemble the Milky Way.
A phenomenological series of simulations of dwarf galaxies placed on different orbits around a Milky Way-like galaxy, in order to learn about the properties (and observability) of tidal tails in dwarf galaxies around our Milky Way.
Our guest Ioanna Arka tells us about a great initiative: the web-based platform www.jobsforastronomers.com, which collects experiences, tips and job posts for “recovering astronomers”.
For the first time, diffuse X-ray emission from young stars is identified in the Small Magellanic Cloud (SMC), using data from Chandra.
