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:…
Preliminary Target Selection for the DESI Bright Galaxy Survey (BGS)
Omar Ruiz-Macias, Pauline Zarrouk, Shaun Cole +28
The Dark Energy Spectroscopic Instrument (DESI) will execute a nearly magnitude-limited survey of low redshift galaxies (, median ). Clustering…
Preliminary Target Selection for the DESI Emission Line Galaxy (ELG) Sample
Anand Raichoor, Daniel J. Eisenstein, Tanveer Karim +26
DESI will precisely constrain cosmic expansion and the growth of structure by collecting 35 million redshifts across 80% of cosmic history and one third of the sky to s…
Preliminary Target Selection for the DESI Quasar (QSO) Sample
Christophe Yèche, Nathalie Palanque-Delabrouille, Charles-Antoine Claveau +24
The DESI survey will measure large-scale structure using quasars as direct tracers of dark matter in the redshift range and using quasar Ly- forests at . We p…
The completed SDSS-IV extended Baryon Oscillation Spectroscopic Survey: Large-scale Structure Catalogues and Measurement of the isotropic BAO between redshift 0.6 and 1.1 for the Emission Line Galaxy Sample
Anand Raichoor, Arnaud de Mattia, Ashley J. Ross +37
We present the Emission Line Galaxy (ELG) sample of the extended Baryon Oscillation Spectroscopic Survey (eBOSS) from the Sloan Digital Sky Survey IV Data Release 16 (DR16). After…
