Interested in helping out with one of the most innovative, grassroots, publishing efforts around? The Journal of Open Source Software (@…) is looking for editors. We conduct collaborative checklist-based peer review of research software using GitHub issues. It's the most positive, rewarding, community-based reviewing/editing work I've ever been a part of.

Wave equations for spin 3/2 quantum fields
In this work, we review formulations of wave equations for spin-3/2 fields constructed from different Lorentz group representations. We analyze the Joss-Weinberg single-spin chiral representation and the double-spin chiral representation, focusing on the structure of their covariant operators. We explore the Duffin-Kemmer-Petiau (DKP) formalism and its algebraic properties, originally introduced for spin--0 and spin-1 particles, and here considered as a potential framework for spin 3/2. As a re…

Sifting for a Stream: The Morphology of the $300S$ Stellar Stream
Stellar streams are sensitive laboratories for understanding the small-scale structure in our Galaxy's gravitational field. Here, we analyze the morphology of the $300S$ stellar stream, which has an eccentric, retrograde orbit and thus could be an especially powerful probe of both baryonic and dark substructures within the Milky Way. Due to extensive background contamination from the Sagittarius stream (Sgr), we perform an analysis combining Dark Energy Camera Legacy Survey photometry, $\textit…
