By popular request, the Astrophysics (astro-ph) archive has been split into six subcategories:

CO Cosmology and Extra-Galactic Astrophysics
EP Earth and Planetary Astrophysics
GA Galactic Astrophysics
HE High Energy Astrophysical Phenomena
IM Instrumentation and Methods for Astrophysics
SR Solar and Stellar Astrophysics

For more information, see the subcategory descriptions at http://arxiv.org/archive/astro-ph (including links to the subdivided new and recent listings). This split should make announcements of new papers more manageable for those interested only in subsets of astro-ph. New astro-ph submissions must assigned one or more sub-categories. (Existing astro-ph articles will be machine-classified according to the new scheme when enough training data has been collected.)

To subscribe to the daily e-mail notifications for only a set of subcategories, you should first cancel your existing subscription, and then subscribe only to the subcategories of interest via physics. See http://arxiv.org/help/subscribe For example, you could send two emails
