We review recent developments and results in testing general relativity (GR) at cosmological
scales. The subject has witnessed rapid growth during the last two decades with the aim of …

The wealth of incoming and future cosmological observations will allow us to map out the
structure and evolution of the observable universe to an unprecedented level of precision …

It is generally believed that long-duration gamma-ray bursts (GRBs) are associated with
massive star core collapse, whereas short-duration GRBs are associated with mergers of …

Type Ia supernovae (SNe Ia) were instrumental in establishing the acceleration of the
universe's expansion. By virtue of their combination of distance reach, precision, and …

In large-scale statistical learning, data collection and model fitting are moving increasingly
toward peripheral devices---phones, watches, fitness trackers---away from centralized data …

We describe the survey design, calibration, commissioning, and emission-line detection
algorithms for the Hobby–Eberly Telescope Dark Energy Experiment (HETDEX). The goal of …

We present the measurement of the Hubble constant, H 0, with three strong gravitational
lens systems. We describe a blind analysis of both PG 1115+ 080 and HE 0435− 1223 as …

ABSTRACT The Baryon Oscillation Spectroscopic Survey (BOSS) is designed to measure
the scale of baryon acoustic oscillations (BAO) in the clustering of matter over a larger …

The current flow of high accuracy astrophysical data, among which are the Cosmic
Microwave Background (CMB) measurements by the Planck satellite, offers an …

We present the design and performance of the multi-object fiber spectrographs for the Sloan
Digital Sky Survey (SDSS) and their upgrade for the Baryon Oscillation Spectroscopic …
