Dr. Oindabi Mukherjee joined the ASCL team in June. She recently received her Ph.D. in Physics from Michigan Technological University (MTU, home of the ASCL; go, Huskies!). She specializes in detecting similarities in the light curves of Gamma-ray Bursts, and is assisting the ASCL with a number of projects. She is also our Social Media Maven. Welcome, Oindabi!

ApJ overtakes MNRAS in number of ASCL citations
In looking at the ASCL dashboard yesterday, I realized that the Astrophysical Journal (ApJ) now has the most citations to ASCL entries, having overtaken (by a hair) Monthly Notices of the Royal Astronomical Society (MNRAS), which has held the top spot since at least 2015. MNRAS‘s early (and enduring) lead in software citations was initially the result of one editor, Dr. Keith T. Smith (now a senior editor at Science), who strongly encouraged article authors to cite the software they had used to generate their results. (Though I obviously saw the effect of his work in MNRAS, I had no idea one person was responsible for it until I saw a post in the Astronomers Facebook group and later queried Keith, who was unknown to me at the time.)
AAS Journals, which publishes ApJ, has three data editors, Greg Schwarz, August Muench, and Katie Merrell, who, though primarily consumed with data work, also encourage software citation, obviously to good effect. And so it grows!

Hand-crafted spam
Nearly every month, ASCL editors notify software authors that their code has been registered in the ASCL. Each editor sends out notifications for the code entries she worked on. I say “nearly every month” because I sometimes get behind in the prep work for the notifications, and that delays all editors who send out these notifications. Editors create their own processes for handling this correspondence.
I refer to my process as “hand-crafted spam.” I send out two types of notifications, one to authors who submitted their software to the ASCL, and another to authors for code entries I created. I have standard text into which I add, one by one, the necessary details for each email, by cutting and pasting the info from an Excel spreadsheet I create just for this purpose. I also check the emails against the ASCL entries to make sure I’ve got the right code and author. This sounds laborious, but it actually doesn’t take much time. This afternoon, I sent out 34 emails covering 39 code entries (some authors had two codes added to the ASCL) for code entries processed in February, March, and April, and it took me, working at a steady but unhurried pace, exactly one hour from the first missive to the last.
I’m putting this here to remind future me that this task goes pretty quickly, so, future me, do this more promptly!

Special Session: Into the Future: Building on 25 Years of Community Organization in Astro Software Development
Abstract: Over the past 25 years, astronomy has seen many changes involving research software development. These include improved transparency, improved software availability, and changes in journal policies. Formal recognition of community-based software development has increased through targeted funding, the establishment of new journals specifically focused on software, and code citation.
Changes in astro software development include the rise of open social coding sites such as GitHub and GitLab, the establishment and growth of conferences devoted to or including research software (such as ADASS, FORCE11, and the Research Data Alliance), and community-based training in software development (for example, The Carpentries and SciCoder) and exploration (for example, .dotastro and hack days) events.
This Special Session will look back at the community-driven work that has enabled some of these changes and look forward to future horizons for the software community in astronomy. Leaders of some of these community efforts will serve on an expert panel and will share their perspectives, after which the floor will be open for discussion with participants.

Abstract: The Astrophysics Source Code Library (ASCL, ascl.net) is an online registry of source codes used in refereed astrophysics research. It currently lists over 3,300 codes and covers all aspects of computational astrophysics, and all of its public metadata about software can be downloaded. This presentation covers possible ways the ASCL can be used by educators and their graduate students. The ASCL serves as a discovery tool for codes that can be used for one’s own research. Graduate students can also investigate existing codes to see how common astronomical problems are approached numerically in practice, and use these codes as benchmarks for their own solutions to these problems. Further, they can deepen their knowledge of software practices and techniques through examination of others’ codes, and can use the ASCL’s data set for research on computational methods in astrophysics.

iPoster: ASCL, ADS, and EMAC: Improving the visibility and citability of exoplanet research software
Alice Allen, Astrophysics Source Code Library; Alberto Accomazzi, Center for Astrophysics | Harvard & Smithsonian; Joe Renaud, UMD College Park / NASA Goddard.
Abstract: The Astrophysics Source Code Library (ASCL, ascl.net) is a free online registry for source codes of interest to astronomers, astrophysicists, and planetary scientists. It lists, and in some cases houses, software used in research that has appeared in, or been submitted to, peer-reviewed publications. It now has over 3300 software entries and is indexed by ADS and Clarivate’s Web of Science. In 2020, NASA created the Exoplanet Modeling and Analysis Center (EMAC, emac.gsfc.nasa.gov). Housed at the Goddard Space Flight Center, EMAC serves, in part, as a catalog and repository for exoplanet research resources. EMAC currently has 223 entries, 77% of which are for downloadable software. This presentation will cover the collaborative work the ASCL is doing with EMAC and with NASA’s Astrophysics Data System (ADS) to increase the discoverability and citability of EMAC’s software entries and to strengthen the ASCL’s and ADS’s ability to serve the planetary science community.
