Data Combination: Interferometry and Single-dish Imaging in Radio Astronomy [PDF]
Publications of the Astronomical Society of the Pacific, 2023 Modern interferometers routinely provide radio-astronomical images down to subarcsecond resolution. However, interferometers filter out spatial scales larger than those sampled by the shortest baselines, which affects the measurement of both spatial and ...

Redback: A Bayesian inference software package for electromagnetic transients [PDF]
Monthly notices of the Royal Astronomical Society, 2023 Fulfilling the rich promise of rapid advances in time-domain astronomy is only possible through confronting our observations with physical models and extracting the parameters that best describe what we see.

HAFFET: Hybrid Analytic Flux FittEr for Transients
The Astrophysical Journal Supplement Series, 2023 The progenitors for many types of supernovae (SNe) are still unknown, and an approach to diagnose their physical origins is to investigate the light-curve brightness and shape of a large set of SNe.

Korg: A Modern 1D LTE Spectral Synthesis Package
The Astronomical Journal, 2023 We present Korg , a new package for 1D LTE spectral synthesis of FGK stars, which computes theoretical spectra from the near-ultraviolet to the near-infrared, and implements both plane-parallel and spherical radiative transfer.

International standards for software structures in astronomy [PDF]
International Astronomical Union Colloquium, 1982 AbstractThe increasing request for astronomical data processing facilities forces the definition of standards for astronomical application software. Separating the application module from the interfaces to the data processing system allows to identify the standard user interaction interface, the standard data storage interface, the standard dedicated ...
