ApJ Letters Latest Papers http://stacks.iop.org/1538-4357 The Letters section was created as Part 2 of The Astrophysical Journal in 1967 by Chandrasekhar. He cited the need for a separate publishing schedule that allowed astrophysicists to rapidly publish short notices of their "spectacular developments in astronomy", Chandrasekhar, 1967, ApJ, 148, 1. In 1971, the Letters obtained its first editor separate from Part 1. For more information on the history of The Astrophysical Journal, see D. Osterbrock, 1995, ApJ, 438, 1. The Letters is a peer-reviewed express scientific journal published in paper and electronic formats for the AAS by IOP Publishing. Manuscripts must meet the same criteria for all papers published in The Astrophysical Journal with the additional criteria of timeliness and brevity. en-gb Copyright © IOP Publishing 2009 Thu, 01 Jan 1970 00:00:00 GMT Thu, 01 Jan 1970 00:00:00 GMT http://syndication.iop.org/about/ custserv@iop.org (Customer Services) The Astrophysical Journal Letters http://images.iop.org/website-logos/ejs_logo.png http://stacks.iop.org/ How Massive are Massive Compact Galaxies? http://stacks.iop.org/1538-4357/706/i=1/a=L188?rss=2.0 Author(s): Adam Muzzin, Pieter van Dokkum, Marijn Franx, Danilo Marchesini, Mariska Kriek, and Ivo Labbe<br>Affiliation(s): Department of Astronomy, Yale University, New Haven, CT 06520-8101, USA; Leiden Observatory, Leiden University, P.O.
