Cosmology and Fundamental Physics with the Euclid Satellite
Luca Amendola, Stephen Appleby, Anastasios Avgoustidis +69
Euclid is a European Space Agency medium class mission selected for launch in 2020 within the Cosmic Vision 2015 2025 program. The main goal of Euclid is to understand the origin o…
PkANN - II. A non-linear matter power spectrum interpolator developed using artificial neural networks
Shankar Agarwal, Filipe B. Abdalla, Hume A. Feldman +2
In this paper we introduce PkANN, a freely available software package for interpolating the non-linear matter power spectrum, constructed using Artificial Neural Networks (ANNs). P…

PkANN - I. Non-linear matter power spectrum interpolation through artificial neural networks
Shankar Agarwal, Filipe B. Abdalla, Hume A. Feldman +2
We investigate the interpolation of power spectra of matter fluctuations using Artificial Neural Network (PkANN). We present a new approach to confront small-scale non-linearities…
Modified Gravity: the CMB, Weak Lensing and General Parameterisations
Shaun A. Thomas, Stephen A. Appleby, Jochen Weller
We examine general physical parameterisations for viable gravitational models in the framework. This is related to the mass of an additional scalar field, called the scalaro…
Excess Clustering on Large Scales in the MegaZ DR7 Photometric Redshift Survey
Shaun A. Thomas, Filipe B. Abdalla, Ofer Lahav
We observe a large excess of power in the statistical clustering of Luminous Red Galaxies in the photometric SDSS galaxy sample called MegaZ DR7. This is seen over the lowest multi…
The Angular Power Spectra of Photometric SDSS LRGs
Shaun A. Thomas, Filipe B. Abdalla, Ofer Lahav
We construct new galaxy angular power spectra based on the extended, updated and final SDSS II Luminous Red Galaxy (LRG) photometric redshift survey: MegaZ DR7. Encapsulating 7746…
Upper Bound of 0.28 eV on the Neutrino Masses from the Largest Photometric Redshift Survey
Shaun A. Thomas, Filipe B. Abdalla, Ofer Lahav
We present a new upper limit of sum m_ν eV < 0.28 (95% CL) on the sum of the neutrino masses assuming a flat LCDM cosmology. This relaxes slightly to sum m_ν < 0.34 and sum m_ν < 0…
