Saturday. Rented a car, drove to IKEA with Zeinab and Jeff, and came back. Bought just under 1000 Euro of furniture (sofa-bed, dining table, dining chairs, and rugs, plus shipping).

Spheroidal post-mergers in the local Universe
Carpineti, et al
Galaxy zoo: 3373 mergers; investigate subset of galaxies from this catalog that are spheroidal 'post-mergers' (SPMs), where a single remnant is in the final stages of relaxation after the merger and shows evidence for a dominant bulge, making them plausible progenitors of early-type galaxies. Results indicate that the SPMs have bluer colours than the general early-type galaxy population possibly due to merger-induced star formation. An analysis using optical emission line ratios indicates that 20 SPMs exhibit LINER or Seyfert-like activity (68%), while the remaining 10 galaxies are classified as either star forming or quiescent. A comparison to the emission line activity in the ongoing mergers indicates that the AGN fraction rises in the post-mergers, suggesting that the AGN phase probably becomes dominant only in the very final stages of the merger process. The optical colours of the SPMs and the plausible mass ratios for their progenitors indicate that, while a minority are consistent with major mergers between two early-type galaxies, the vast majority are remnants of major mergers where at least one progenitor is a late-type galaxy.
