Evolution of linear matter perturbations with error-bounded bundle physics-informed neural networks
Luca Gomez Bachar, Augusto T. Chantada, Susana J. Landau +2
We consider the evolution of linear matter perturbations in the context of the standard cosmological model (CDM) and a phenomenological modified gravity model. We use the physic…
The advantage of Bolometric Interferometry for controlling Galactic foreground contamination in CMB primordial B-modes measurements
E. Manzan, M. Regnier, J-Ch. Hamilton +18
In the quest for the faint primordial B-mode polarization of the Cosmic Microwave Background, three are the key requirements for any present or future experiment: an utmost sensiti…
Identifying frequency decorrelated dust residuals in B-mode maps by exploiting the spectral capability of bolometric interferometry
M. Regnier, E. Manzan, J. -Ch Hamilton +21
Astrophysical polarized foregrounds represent the most critical challenge in Cosmic Microwave Background (CMB) B-mode experiments. Multi-frequency observations can be used to const…
Tracking the orbit of unresolved subhalos for semi-analytic models
Facundo M. Delfino, Claudia G. Scoccola, Sofia A. Cora +2
We present a model to track the orbital evolution of "unresolved subhaloes" (USHs) in cosmological simulations. USHs are subhaloes that are no longer distinguished by halo finders…
The clustering of galaxies in the completed SDSS-III Baryon Oscillation Spectroscopic Survey: cosmological analysis of the DR12 galaxy sample
Shadab Alam, Metin Ata, Stephen Bailey +69
We present cosmological results from the final galaxy clustering data set of the Baryon Oscillation Spectroscopic Survey, part of the Sloan Digital Sky Survey III. Our combined gal…
SDSS-III Baryon Oscillation Spectroscopic Survey Data Release 12: galaxy target selection and large scale structure catalogues
Beth Reid, Shirley Ho, Nikhil Padmanabhan +39
The Baryon Oscillation Spectroscopic Survey (BOSS), part of the Sloan Digital Sky Survey (SDSS) III project, has provided the largest survey of galaxy redshifts available to date,…
The clustering of galaxies in the SDSS-III Baryon Oscillation Spectroscopic Survey: mock galaxy catalogues for the BOSS Final Data Release
Francisco-Shu Kitaura, Sergio Rodriguez-Torres, Chia-Hsun Chuang +20
We reproduce the galaxy clustering catalogue from the SDSS-III Baryon Oscillation Spectroscopic Survey Final Data Release (BOSS DR11&DR12) with high fidelity on all relevant scales…
nIFTy Cosmology: Galaxy/halo mock catalogue comparison project on clustering statistics
Chia-Hsun Chuang, Cheng Zhao, Francisco Prada +21
We present a comparison of major methodologies of fast generating mock halo or galaxy catalogues. The comparison is done for two-point and the three-point clustering statistics. Th…
Hunting down systematics in baryon acoustic oscillations after cosmic high noon
Francisco Prada, Claudia G. Scoccola, Chia-Hsun Chuang +5
Future dark energy experiments will require better and more accurate theoretical predictions for the baryonic acoustic oscillations (BAO) signature in the spectrum of cosmological…
Cosmological implications of baryon acoustic oscillation (BAO) measurements
Éric Aubourg, Stephen Bailey, Julian E. Bautista +90
We derive constraints on cosmological parameters and tests of dark energy models from the combination of baryon acoustic oscillation (BAO) measurements with cosmic microwave backgr…
Constraining the halo bispectrum in real and redshift space from perturbation theory and non-linear stochastic bias
Francisco-Shu Kitaura, Héctor Gil-Marín, Claudia Scoccola +4
We present a method to produce mock galaxy catalogues with efficient perturbation theory schemes, which match the number density, power spectra and bispectra in real and in redshif…
The clustering of galaxies in the SDSS-III Baryon Oscillation Spectroscopic Survey: Baryon Acoustic Oscillations in the Data Release 10 and 11 galaxy samples
Lauren Anderson, Eric Aubourg, Stephen Bailey +62
We present a one per cent measurement of the cosmic distance scale from the detections of the baryon acoustic oscillations in the clustering of galaxies from the Baryon Oscillation…
The SDSS-III Baryonic Oscillation Spectroscopic Survey: Constraints on the Integrated Sachs Wolfe effect

Lauren Anderson, Eric Aubourg, Stephen Bailey +73
We present measurements of galaxy clustering from the Baryon Oscillation Spectroscopic Survey (BOSS), which is part of the Sloan Digital Sky Survey III (SDSS-III). These use the Da…
Variation of the fine structure constant and the electron mass at early Universe
Claudia G. Scóccola
In this thesis, we focus on the study of the variation of the electron mass , and the fine structure constant , at different cosmic times. We analyze the details of the rec…
Observing the Evolution of the Universe
James Aguirre, Alexandre Amblard, Amjad Ashoorioon +172
How did the universe evolve? The fine angular scale (l>1000) temperature and polarization anisotropies in the CMB are a Rosetta stone for understanding the evolution of the univers…
The Origin of the Universe as Revealed Through the Polarization of the Cosmic Microwave Background
