A new Elsevier journal was announced earlier this week: Astronomy and Computing (ASCOM). The journal will focus on the broad area between astronomy, computer science and information technology and aims to publish work in all aspects of astronomical computing. If you are interested in publishing here, please read their Guide for Authors.
Please note: this is a traditional peer-reviewed journal that gives you the option to pay for your article to become freely available. Unfortunately, this does not meet the criteria for funding from the Compact for Open Access Publishing Equity, which supports work published in open access journals. If you have questions, please ask your favorite librarian!
