k+a galaxies

Well, the 2SLAQ Survey is really firing on all cylinders now. Roseboom et al. appeared on the pre-prints this a.m. The way I read it, the bottom line is that "simple" star-formation activity (which manifests itself in the appearance of k+a and em+a LRG spectra) is not sufficient to explain the bulk of mass growth in early types from z~1. Thus "dry" mergers (i.e. mergers which have very little gas associated with them e.g. Bell et al. 2005) probably play a major role in this early type mass build-up.

As far as my stuff goes, the current wall I'm trying to walk around is that of creating a decent mask for our March (!!) AAOmega data. I thinking of giving up on the "bullseye" idea and going back to simple squares.

Have a good weekend.
