Principled point-source detection in collections of astronomical images
Dustin Lang, David W. Hogg
We review the well-known matched filter method for the detection of point sources in astronomical images. This is shown to be optimal (that is, to saturate the Cramer--Rao bound) u…
A hybrid Fourier--Real Gaussian Mixture method for fast galaxy--PSF convolution
Dustin Lang
I present a method for the fast convolution of a model galaxy profile by a point-spread function (PSF) model represented as a pixel grid. The method relies upon three observations:…
Discovering New Strong Gravitational Lenses in the DESI Legacy Imaging Surveys
X. Huang, C. Storfer, A. Gu +14
We have conducted a search for new strong gravitational lensing systems in the Dark Energy Spectroscopic Instrument Legacy Imaging Surveys' Data Release 8. We use deep residual neu…
Observing Strategy for the Legacy Surveys
Kaylan J. Burleigh, Martin Landriau, Arjun Dey +19
The Legacy Surveys, a combination of three ground-based imaging surveys, have mapped 16,000 deg in three optical bands (, , and ) to a depth 1--~mag deeper than the…
