Galaxy Morphology Classification using Neural Ordinary Differential Equations

Raghav Gupta, P. K. Srijith, Shantanu Desai

We introduce a continuous depth version of the Residual Network (ResNet) called Neural ordinary differential equations (NODE) for the purpose of galaxy morphology classification. W…

Dark Energy Survey Year 3 Results: Point-Spread Function Modeling

M. Jarvis, G. M. Bernstein, A. Amon +79

We introduce a new software package for modeling the point-spread function (PSF) of astronomical images, called Piff (PSFs In the Full FOV), which we apply to the first three years…

Reducing ground-based astrometric errors with Gaia and Gaussian processes

W. F. Fortino, G. M. Bernstein, P. H. Bernardinelli +64

Stochastic field distortions caused by atmospheric turbulence are a fundamental limitation to the astrometric accuracy of ground-based imaging. This distortion field is measurable…

Optical follow-up of gravitational wave triggers with DECam during the first two LIGO/VIRGO observing runs

K. Herner, J. Annis, D. Brout +82

Gravitational wave (GW) events detectable by LIGO and Virgo have several possible progenitors, including black hole mergers, neutron star mergers, black hole--neutron star mergers,…
