Remarks on notability: 2 x peer-reviewed scientific articles, and multiple instances of coverage in the popular WP:RS press, of which I've cited only two of the many. -- The Anome (talk) 02:00, 7 March 2015 (UTC)[reply]

The stated number 9.3[4] billion is not the comoving distance in light-years but the lookback time in years. The correct comoving distance for z = 1.49 is 14.4 billion light-years. Archelon (talk) 14:51, 9 March 2015 (UTC)[reply]
