Journal Club: Next Week (7th Dec)

This is none! This is because if there were a journal club it would clash with the talk by Yau at 11:30am in MR2, which most of us would probably rather attend.

The CTC/DAMTP journal club will therefore reconvene next in the new year on Tuesday 18th January 2011.

Paper Suggestions: 27/11-3/12

This is an open thread. Please use the comments to post your suggestions for interesting papers that you have read / noticed and could / would be worth discussing. Thanks

Journal Club: 30/11/10

The cosmology journal club will meet again today (Tuesday 30th Novemeber 2010) at 11:30am (after coffee) in the Pavillion B common room (B1.19).

This week has a modified gravity / `new physics' feel with Jeremy Sakstein  leading the discussion on:

Stellar Structure and Tests of Modified Gravity
Philip Chang, Lam Hui
arXiv:1011.4107

and me (Douglas Shaw) leading the discussion on the ambitous and controversial Penrose & Gurzadyan preprint:

Concentric circles in WMAP data may provide evident of violent pre-Big-Bang activity

V. G. Gurzadyan, R. Penrose

arXiv:1011.3706

Full paper details follow:

Weekly Round-Up: 20/11-26/11

New Cosmology Journal Club Blog

Welcome to the new DAMTP cosmology journal club blog.  This blog will feature:

1. Each week, there will also be an open thread to which  members of the group can use the comments feature to post details of interesting papers they have read and / or papers that could / should  be discussed at an upcoming journal club. 
2. Each Friday, we will collate all the group paper suggestions from the open thread and our own suggestions into a list of interesting / intriguing paper that are candidates for discussion.
3. Full details of this weeks journal club including links to the papers and abstracts (click read more for the abstracts).
4. Other cosmology news / events that might be of interest to the group.
