| Caustics: A Python Package for Accelerated Strong Gravitational Lensing Simulations | Gravitational lensing is the deflection of light rays due to the gravity of intervening masses. This phenomenon is observed in a variety of scales and configurations, involving any non-uniform mass such as planets, stars, galaxies, clusters of galaxies, and even the large scale structure of the universe. Strong lensing occurs when the distortions are… | August 7, 2024 August 7, 2024 |
| AstroPhot: Fitting Everything Everywhere All at Once in Astronomical Images | We present AstroPhot, a fast, powerful, and user-friendly Python based astronomical image photometry solver. AstroPhot incorporates automatic differentiation and GPU (or parallel CPU) acceleration, powered by the machine learning library PyTorch. Everything: AstroPhot can fit models for sky, stars, galaxies, PSFs, and more in a principled χ2 forward optimization, recovering Bayesian posterior information and… | August 17, 2023 August 7, 2024 |
| PROBES. I. A Compendium of Deep Rotation Curves and Matched Multiband Photometry | We present the Photometry and Rotation Curve Observations from Extragalactic Surveys (PROBES) compendium of extended rotation curves for 3163 late-typespirals, with matching homogeneous multiband photometry for 1677 of them.PROBES rotation curves originally extracted from Halpha long-slit spectra andaperture synthesis HI (21cm) velocity maps typically extend out to a median2R_e (or 1R_{23.5, r}).
