Context. Baryon acoustic oscillations (BAO) are imprinted in the density field by acoustic waves travelling in the plasma of the early universe. Their fixed scale can be used as a standard ruler to study the geometry of the universe. Aims. The BAO have been previously detected using correlation functions and power spectra of the galaxy distribution. We present a new method to detect the real-space structures associated with BAO. These baryon acoustic structures are spherical shells of… Expand

Baryon acoustic oscillations (BAOs) are a feature imprinted in the galaxy distribution by acoustic waves traveling in the plasma of the early universe. Their detection at the expected scale inExpand
Large-scale structures in the universe are a powerful tool to test cosmological models and constrain cosmological parameters. A particular feature of interest comes from baryon acoustic oscillationsExpand
Density-dependent clustering - I. Pulling back the curtains on motions of the BAO peak
The most common statistic used to analyse large-scale structure surveys is the correlation function, or power spectrum. Here, we show how ‘slicing’ the correlation function on local density bringsExpand
Quasi-periodical features in the distribution of Luminous Red Galaxies
A statistical analysis of radial distributions of Luminous Red Galaxies (LRGs) from the Sloan Digital Sky Survey (SDSS DR7) catalogue within an interval 0.16≤z≤0.47 is carried out. We found that theExpand
The 6dF Galaxy Survey: baryon acoustic oscillations and the local Hubble constant
We analyse the large-scale correlation function of the 6dF Galaxy Survey (6dFGS) and detect a baryon acoustic oscillation (BAO) signal at 105h −1 Mpc. The 6dFGS BAO detection allows us to constrainExpand
Observational probes of cosmic acceleration
The accelerating expansion of the universe is the most surprising cosmological discovery in many decades, implying that the universe is dominated by some form of “dark energy” with exotic physicalExpand
Shell-like structures in our cosmic neighbourhood
Signatures of the processes in the early Universe are imprinted in the cosmic web. Some of them may define shell-like structures characterised by typical scales. We search for shell-like structuresExpand
Unusual A2142 supercluster with a collapsing core: distribution of light and mass
We study the distribution, masses, and dynamical properties of galaxy groups in the A2142 supercluster. We analyse the global luminosity density distribution in the supercluster and divide theExpand

Context. There have been many efforts to correct systematic effects in astronomical light curves to improve the detection and characterization of planetary transits and astrophysical variability.Expand
The Physics of Galaxy Formation and Evolution
Until recently the great majority of naturalists believed that species were immutable productions, and had been separately created. This view has been ably maintained by many authors. Some fewExpand


What is the best way to measure baryonic acoustic oscillations
Oscillations in the baryon-photon fluid prior to recombination imprint different signatures on the power spectrum and correlation function of matter fluctuations. The measurement of these featuresExpand
The correlation function of the distribution of matter in the universe shows, at large scales, baryon acoustic oscillations, which were imprinted prior to recombination. This feature was firstExpand
Have Baryonic Acoustic Oscillations in the galaxy distribution really been measured
Recent publications claim that there is no convincing evidence for measurements of the baryonic acoustic oscillation (BAO) feature in galaxy samples using either monopole or radial information.Expand
Detection of the baryon acoustic peak in the large-scale correlation function of SDSS luminous red galaxies
We present the large-scale correlation function measured from a spectroscopic sample of 46,748 luminous red galaxies from the Sloan Digital Sky Survey. The survey region covers 0.72h −3 Gpc 3 overExpand
On the Robustness of the Acoustic Scale in the Low-Redshift Clustering of Matter
We discuss the effects of nonlinear structure formation on the signature of acoustic oscillations in the late-time galaxy distribution. We argue that the dominant nonlinear effect is the differentialExpand
Nonlinear evolution of baryon acoustic oscillations
We study the nonlinear evolution of baryon acoustic oscillations in the dark matter power spectrum and the correlation function using renormalized perturbation theory. In a previous paper we showedExpand
The onion universe: all sky lightcone simulations in spherical shells
Galaxy surveys provide a large-scale view of the universe that typically has a limited line of sight or redshift resolution. The lack of radial accuracy in these surveys can be modelled by picturingExpand
