Thursday. I want to go through astro-ph for the past 2-3 days, so that I can join in the conversation of Christiano's group tomorrow. I also want to start a cosmology astro-ph with Laura. Housing search is moving along--I have sent an application to an apartment right along the Rhine (Rheins, in Deutsch), but it's a bit expensive there.... I'm hoping to find a cheaper place that I would like to live in (center city would be nice).

The orientation of disk galaxies around large cosmic voids
Varela, Betancort-Rijo, Trujillo, Ricciardelli
Using SDSS7, find large voids, and surrounding sprials. For large voids (r > 15Mpc/h), sprials w/in 5Mpc/h shell have ~2sigma significance of angular momentum aligned in the radial direction of the void. For r<15Mpc/h, the alignment is consistent with random. Alignment strength dependent on distance from void surface. Galaxy alignment trend observed similar to minor axis of DM halos around cosmic voids found in cosmological simulations, suggesting possible link in the evolution of both components.
