The Astrophysics Source Code Library (ASCL, http://ascl.net/) is an on-line registry of over 700 source codes that are of interest to astrophysicists, with more being added regularly. The ASCL actively seeks out codes as well as accepting submissions from the code authors, and all entries are citable and indexed by ADS. All codes have been used to generate(More)
Vocal communication is a primary communication method of killer and pilot whales, and is used for transmitting a broad range of messages and information for short and long distance. The large variation in call types of these species makes it challenging to categorize them. In this study, sounds recorded by audio sensors carried by ten killer whales and(More)
The increasing importance of digital sky surveys collecting many millions of galaxy images has reinforced the need for robust methods that can perform morphological analysis of large galaxy image databases. Citizen science initiatives such as Galaxy Zoo showed that large datasets of galaxy images can be analyzed effectively by non-scientist volunteers, but(More)
While software and algorithms have become increasingly important in astronomy, the majority of authors who publish computational astronomy research do not share the source code they develop, making it difficult to replicate and reuse the work. In this paper we discuss the importance of sharing scientific source code with the entire astrophysics community,(More)
—Papyrologists analyze, transcribe, and edit papyrus fragments in order to enrich modern lives by better understanding the linguistics, culture, and literature of the ancient world. One of their common tasks is to match an unknown fragment to a known manuscript. This is especially challenging when the fragments are damaged and contain only limited(More)
The Astrophysics Source Code Library (ASCL) 1 is a free online registry of codes used in astronomy research; it currently contains over 900 codes and is indexed by ADS. The ASCL has recently moved a new infrastructure into production. The new site provides a true database for the code entries and integrates the WordPress news and information pages and the(More)
—Scholars working on vast archives of ancient fragmentary manuscripts have long faced the problem of managing and intuitively interfacing the exponential growth of data as fragments are re-edited over time. Multiple readings, multiple versions, and the reality of a multi-text are concepts not well-suited to the physical codex. Current digital archives and(More)
The past year has seen movement on several fronts for improving software citation , including the Center for Open Science's Transparency and Openness Promotion (TOP) Guidelines, the Software Publishing Special Interest Group that was started at January's AAS meeting in Seattle at the request of that organization's Working Group on Astronomical Software, a(More)
—In the late nineteenth century, two excavators from the University of Oxford uncovered a vast trove of naturally deteriorated papyri, numbering over 500,000 fragments, from the city of Oxyrhynchus. With varying levels and forms of deterioration, the identification of a papyrus fragment can become a repetitive, long, and exhausting process for a(More)
