LSST: from Science Drivers to Reference Design and Anticipated Data Products

Željko Ivezić, +312 more
- 15 May 2008 - 
TL;DR: The LSST design is driven by four main science themes: probing dark energy and dark matter, taking an inventory of the solar system, exploring the transient optical sky, and mapping the Milky Way.

The clustering of galaxies in the completed SDSS-III Baryon Oscillation Spectroscopic Survey: cosmological analysis of the DR12 galaxy sample

Shadab Alam, +90 more
TL;DR: In this article, the authors present cosmological results from the final galaxy clustering data set of the Baryon Oscillation Spectroscopic Survey, part of the Sloan Digital Sky Survey III.

The clustering of galaxies in the sdss-iii baryon oscillation spectroscopic survey: Baryon acoustic oscillations in the data release 9 spectroscopic galaxy sample

Lauren Anderson, +76 more
TL;DR: In this paper, the authors present a measurement of the cosmic distance scale from detections of the baryon acoustic oscillations in the clustering of galaxies from the Baryon Oscillation Spectroscopic Survey (BOSS), which is part of the Sloan Digital Sky Survey III (SDSS-III).
Journal ArticleDOI

$f(R,T)$ gravity

TL;DR: In this article, the authors considered a modified theory of gravity, where the gravitational Lagrangian is given by an arbitrary function of the Ricci scalar and of the trace of the stress-energy tensor.

Precision cluster mass determination from weak lensing

TL;DR: In this paper, a new statistic ϒ(R;R0) was proposed for estimating the masses of galaxy clusters, which completely eliminates mass contributions below a chosen scale (which should be about 20 per cent of the virial radius).
Journal ArticleDOI

The signatures of large-scale temperature and intensity fluctuations in the Lyman α forest

TL;DR: In this paper, the authors used toy temperature models and detailed heating histories from cosmological simulations of He II reionization to study the consequences of inhomogeneous heating for the Lyα forest and found that physically motivated temperature models can alter P F at an order unity level at k ≲ 0.1 comoving Mpc −1, a magnitude that should be easily detectable with BOSS.

Red-sequence cluster finding in the Millennium Simulation

TL;DR: In this article, the authors investigate halo mass selection properties of red-sequence cluster finders using galaxy populations of the Millennium Simulation (MS) and find that 90 per cent of the clusters found have galaxy membership dominated by a single, real-space halo, and that 10 per cent are blended systems for which no single halo contributes a majority of a cluster's membership.
Journal ArticleDOI

An improved calculation of the non-Gaussian halo mass function

TL;DR: In this paper, the authors improved upon the existing results for the mass function by combining path integral methods and saddle point techniques, and carefully account for the various scale dependent combinations of small parameters which appear.
Journal ArticleDOI

Cosmography with cluster strong lenses: the influence of substructure and line-of-sight haloes

TL;DR: In this article, the authors explore the use of strong lensing by galaxy clusters to constrain the dark energy equation of state and its possible time variation and employ Monte Carlo simulations of cluster lenses, including the contribution from substructures, to assess the feasibility of this potentially powerful technique.
