Astrophysical Tests of Modified Gravity: the Morphology and Kinematics of Dwarf Galaxies
Vinu Vikram, Anna Cabre, Bhuvnesh Jain +1
This paper is the third in a series on tests of gravity using observations of stars and nearby dwarf galaxies. We carry out four distinct tests using published data on the kinemati…
Cross-Correlation of spectroscopic and photometric galaxy surveys: cosmology from lensing and redshift distortions
E. Gaztanaga, M. Eriksen, M. Crocce +5
Cosmological galaxy surveys aim at mapping the largest volumes to test models with techniques such as cluster abundance, cosmic shear correlations or baryon acoustic oscillations (…
Clustering of Photometric Luminous Red Galaxies II: Cosmological Implications from the Baryon Acoustic Scale
A. Carnero, E. Sanchez, M. Crocce +2
A new determination of the sound horizon scale in angular coordinates is presented. It makes use of ~ 0.6 x 10^6 Luminous Red Galaxies, selected from the Sloan Digital Sky Survey i…
Clustering of photometric luminous red galaxies I : Growth of Structure and Baryon Acoustic Feature
Martin Crocce, Enrique Gaztanaga, Anna Cabre +2
The possibility of measuring redshift space (RSD) distortions using photometric data have been recently highlighted. This effect complements and significantly alters the detectabil…
Measuring Redshift-Space Distortions using Photometric Surveys
Ashley J Ross, Will J Percival, Martin Crocce +2
We outline how redshift-space distortions (RSD) can be measured from the angular correlation function w(θ), of galaxies selected from photometric surveys. The natural degeneracy be…
Have Baryonic Acoustic Oscillations in the galaxy distribution really been measured?
Anna Cabre, Enrique Gaztanaga
Recent publications claim that there is no convincing evidence for measurements of the baryonic acoustic (BAO) feature in galaxy samples using either monopole or radial information…
Tracing The Sound Horizon Scale With Photometric Redshift Surveys
E. Sanchez, A. Carnero, J. Garcia-Bellido +6
We propose a new method for cosmological parameters extraction using the baryon acoustic oscillation scale as a standard ruler in deep galaxy surveys with photometric determination…
Modeling the angular correlation function and its full covariance in Photometric Galaxy Surveys
Martin Crocce, Anna Cabre, Enrique Gaztañaga
Near future cosmology will see the advent of wide area photometric galaxy surveys, like the Dark Energy Survey (DES), that extent to high redshifts (z ~ 1 - 2) but with poor radial…
Cosmological parameter constraints from SDSS luminous red galaxies: a new treatment of large-scale clustering
Ariel G. Sanchez, M. Crocce, A. Cabre +2
We apply a new model for the spherically averaged correlation function at large pair separations to the measurement of the clustering of luminous red galaxies (LRGs) made from the…
The anisotropic redshift space galaxy correlation function: detection on the BAO Ring
Enrique Gaztanaga, Anna Cabre
In a series of papers we have recently studied the clustering of LRG galaxies in the latest spectroscopic SDSS data release, which has 75000 LRG galaxies sampling 1.1 Gpc^3/h^3 to…
Clustering of Luminous Red Galaxies IV: Baryon Acoustic Peak in the Line-of-Sight Direction and a Direct Measurement of H(z)
Enrique Gaztanaga, Anna Cabre, Lam Hui
We study the clustering of LRG galaxies in the latest spectroscopic SDSS data releases, DR6 and DR7, which sample over 1 Gpc^3/h^3 to z=0.47. The 2-point correlation function $\xis…
Clustering of luminous red galaxies II: small scale redshift space distortions
Anna Cabre, Enrique Gaztanaga
This is the second paper of a series where we study the clustering of LRG galaxies in the latest spectroscopic SDSS data release, DR6, which has 75000 LRG galaxies covering over 1…
Clustering of luminous red galaxies I: large scale redshift space distortions

Clustering of Luminous Red Galaxies III: Detection of the Baryon Acoustic Peak in the 3-point Correlation Function
E. Gaztanaga, A. Cabre, F. Castander +2
We present the 3-point function ξ_3 and Q_3=ξ_3/ξ_2^2 for a spectroscopic sample of luminous red galaxies (LRG) from SDSS DR6 & DR7. We find a strong (S/N6) detection of o…
Error analysis in cross-correlation of sky maps: application to the ISW detection
Anna Cabre, Pablo Fosalba, Enrique Gaztanaga +1
Constraining cosmological parameters from measurements of the Integrated Sachs-Wolfe effect requires developing robust and accurate methods for computing statistical errors in the…
Cross-correlation of WMAP 3rd year and the SDSS DR4 galaxy survey: new evidence for Dark Energy
A. Cabre, E. Gaztanaga, M. Manera +2
We cross-correlate the third-year WMAP data with galaxy samples extracted from the SDSS DR4 (SDSS4) covering 13% of the sky, increasing by a factor of 3.7 the volume sampled in pre…
