Bright Star Subtraction Pipeline for LSST: Phase one report
Amir E. Bazkiaei, Lee S. Kelvin, Sarah Brough +3
We present the phase one report of the Bright Star Subtraction (BSS) pipeline for the Vera C. Rubin Observatory's Legacy Survey of Space and Time (LSST). This pipeline is designed…
Galaxy Image Restoration with Shape Constraint
Fadi Nammour, Morgan A. Schmitz, Fred Maurice Ngolè Mboula +2
Images acquired with a telescope are blurred and corrupted by noise. The blurring is usually modeled by a convolution with the Point Spread Function and the noise by Additive Gauss…
Periodic Astrometric Signal Recovery through Convolutional Autoencoders
Michele Delli Veneri, Louis Desdoigts, Morgan A. Schmitz +8
Astrometric detection involves a precise measurement of stellar positions, and is widely regarded as the leading concept presently ready to find earth-mass planets in temperate orb…
Euclid: Nonparametric point spread function field recovery through interpolation on a graph Laplacian
M. A. Schmitz, J. -L. Starck, F. Ngole Mboula +35
Context. Future weak lensing surveys, such as the Euclid mission, will attempt to measure the shapes of billions of galaxies in order to derive cosmological information. These surv…
