Astronomy problems often involve data from diverse instruments and archives. In Julia, all essential tools are available and work together, offering a uniquely performant and uniform workflow. We'll explore how Julia ecosystem tackles the full range of steps when working with astronomy catalogs, large and small.
Astronomy and astrophysics frequently involve using surveys, catalogs, or archival data from various sources. Observational data spans different wavelengths, times, and observatories - a wide range of sizes and access modes, local or online. In this talk, I will showcase the relevant building blocks available in Julia, and demonstrate how they work together.
The power of Julia facilitates key packages at every step working together: from coordinates and their uncertainties (SkyCoords.jl, Uncertain.jl), to querying and matching catalogs (VirtualObservatory.jl, FlexiJoins.jl), to combining them with images (SkyImages.jl), plotting (Makie.jl) and analyzing the results. Heavy use of multiple dispatch enables a uniform syntax to operate on in-memory datasets, local files, and remote Virtual Observatory services.
In addition to highlighting existing packages and their interoperability, I'll touch on niches that could use more integrations for common tasks.
