Dear Colleagues,

on Tuesday, April the 14th, we will have a journal club at 12:40.

I think I would embark on a crazy attempt to discuss some more

observational aspects of cosmology. I offer to consider the recent

papers which are listed below. We will do as many of them as time

permits. And I hope to serve all the leftovers at later times. :)

David Kraljic, Subir Sarkar. How rare is the Bullet Cluster (in a Î›CDM

universe)?

Trevisan, Matias Zaldarriaga. Detecting Primordial B-Modes after Planck.

L. Amendola, E. Menegoni, C. Di Porto, M. Corsi, E. Branchini.

Constraints on a scale-dependent bias from galaxy clustering.
