Nov 4 Recap

Today's journal club was hosted by Prof. Michael De Robertis.

1. GRB 090423, redshift about 8.2, is the most distant astronomical object ever detect in the Universe. Read it at Nature News & Views here. Bursted just about 600 Myrs after the big bang, it might shed some light on the cosmic 'dark ages'. Two individual groups studied the mechanisms and progenitors of this burst. Their papers are published in the same issue of Nature at page1254 and page 1258.
