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.

The carnegie supernova project: First near-infrared hubble diagram to z 0.7

TL;DR: The Carnegie Supernova Project (CSP) is designed to measure the luminosity distance for Type Ia supernovae (SNe Ia) as a function of redshift, and to set observational constraints on the dark energy contribution to the total energy content of the universe as mentioned in this paper.

Cepheid period-luminosity relations in the near-infrared and the distance to m31 from the hubble space telescope wide field camera 3*

TL;DR: In this paper, the authors presented measurements of 68 classical Cepheids, most detected from the Canada-France-Hawaii Telescope POMME Survey, with periods from 10 to 78 days observed in the near-infrared by the Panchromatic Hubble Andromeda Treasury Program using the Wide Field Camera 3 (WFC3) on the Hubble Space Telescope.

Figure of merit for dark energy constraints from current observational data

TL;DR: In this paper, the authors show that for a set of dark energy parameters, it is most intuitive to define the appropriate figure of merit (FoM) for dark energy constraints, and demonstrate two useful choices of ${{f}_{i}}$ using 182 SNe Ia (from the HST/GOODS program, the first year Supernova Legacy Survey, and nearby SN Ia surveys).

Means of confusion: how pixel noise affects shear estimates for weak gravitational lensing

TL;DR: In this paper, the authors provide a concise overview of the impact of pixel noise on weak-lensing measurements, covering the entire path from noisy images to shear estimates, and identify and discuss several fundamental problems and show that each of them is able to introduce biases in the range of a few tens to a few per cent for galaxies with typical significance levels.
Journal ArticleDOI

Galaxy-Galaxy Flexion: Weak Lensing to Second Order

TL;DR: In this article, the authors developed a new gravitational lensing inversion technique based on the shapelets formalism of Refregier, which can be used to detect a lensing signal with increased signal-to-noise ratio.
