Optimizing the LSST Observing Strategy for Dark Energy Science: DESC Recommendations for the Wide-Fast-Deep Survey
Michelle Lochner, Daniel M. Scolnic, Humna Awan +33
Cosmology is one of the four science pillars of LSST, which promises to be transformative for our understanding of dark energy and dark matter. The LSST Dark Energy Science Collabo…
First Cosmological Results using Type Ia Supernovae from the Dark Energy Survey: Measurement of the Hubble Constant
E. Macaulay, R. C. Nichol, D. Bacon +106
We present an improved measurement of the Hubble constant (H_0) using the 'inverse distance ladder' method, which adds the information from 207 Type Ia supernovae (SNe Ia) from the…
The LSST Dark Energy Science Collaboration (DESC) Science Requirements Document
The LSST Dark Energy Science Collaboration, Rachel Mandelbaum, Tim Eifler +32
The Large Synoptic Survey Telescope (LSST) Dark Energy Science Collaboration (DESC) will use five cosmological probes: galaxy clusters, large scale structure, supernovae, strong le…
Is every strong lens model unhappy in its own way? Uniform modelling of a sample of 13 quadruply+ imaged quasars
A. J. Shajib, S. Birrer, T. Treu +70
Strong-gravitational lens systems with quadruply-imaged quasars (quads) are unique probes to address several fundamental problems in cosmology and astrophysics. Although they are i…
A precise extragalactic test of General Relativity
Thomas E. Collett, Lindsay J. Oldham, Russell J. Smith +7
Einstein's theory of gravity, General Relativity, has been precisely tested on Solar System scales, but the long-range nature of gravity is still poorly constrained. The nearby str…
Detecting strongly lensed supernovae at z ~ 5-7 with LSST
Claes-Erik Rydberg, Daniel J. Whalen, Matteo Maturi +4
Supernovae (SNe) could be powerful probes of the properties of stars and galaxies at high redshifts in future surveys. Wide fields and longer exposure times are required to offset…
SDSS-IV MaNGA: The Spectroscopic Discovery of Strongly Lensed Galaxies
Michael S. Talbot, Joel R. Brownstein, Adam S. Bolton +11
We present a catalogue of 38 spectroscopically detected strong galaxy-galaxy gravitational lens candidates identified in the Sloan Digital Sky Survey IV (SDSS-IV). We were able to…
Serendipitous discovery of a strong-lensed galaxy in integral field spectroscopy from MUSE
Lluís Galbany, Thomas E. Collett, Jairo Méndez-Abreu +3
2MASX J04035024-0239275 is a bright red elliptical galaxy at redshift 0.0661 that presents two extended sources at 2\arcsec~to the north-east and 1\arcsec~to the south-west. The si…
The Impact of Microlensing on the Standardisation of Strongly Lensed Type Ia Supernovae
Max Foxley-Marrable, Thomas E. Collett, Georgios Vernardos +2
We investigate the effect of microlensing on the standardisation of strongly lensed Type Ia supernovae (GLSNe Ia). We present predictions for the amount of scatter induced by micro…
