The Dark Energy Spectroscopic Instrument (DESI) has embarked on an ambitious five-year survey to explore the nature of dark energy with spectroscopy of 40 million galaxies and quas…
Eight-year Full-depth unWISE Coadds
Aaron M. Meisner, Dustin Lang, Edward F. Schlafly +1
We present deep, full-sky maps built from Wide-field Infrared Survey Explorer (WISE) and NEOWISE exposures spanning the 2010 January - 2020 December time period. These coadds, whic…
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…
LRP2020: Probing Diverse Phenomena through Data-Intensive Astronomy
Mubdi Rahman, Dustin Lang, Renée Hložek +2
The era of data-intensive astronomy is being ushered in with the increasing size and complexity of observational data across wavelength and time domains, the development of algorit…
unWISE Coadds: The Five-year Data Set
A. M. Meisner, D. Lang, E. F. Schlafly +1
We present full-sky coadded maps created by uniformly combining the first five years of Wide-field Infrared Survey Explorer (WISE) and NEOWISE imaging at 3.4 microns (W1) and 4.6 m…
Astro2020 APC White Paper: The MegaMapper: a z > 2 spectroscopic instrument for the study of Inflation and Dark Energy
David J. Schlegel, Juna A. Kollmeier, Greg Aldering +74
MegaMapper is a proposed ground-based experiment to measure Inflation parameters and Dark Energy from galaxy redshifts at 2<z<5. A 6.5-m Magellan telescope will be coupled with DES…
