Interesting Astrophysics: Turkey Edition


The latest batch of preprints and papers I consider interesting, assembled between November 24th and November 28th, 2008.

The galaxy shown is the edge-on spiral galaxy NGC 5907 (from APOD), showing the faint stellar streams in its halo that are all that remains of a smaller satellite galaxy that has been tidally disrupted and absorbed by NGC 5907. See the Martínez-Delgado et al paper linked to below.
