Journal ArticleDOI
Cosmological Parameters Degeneracies and Non-Gaussian Halo Bias
TL;DR: In this article, the impact of the cosmological parameters uncertainties on the measurements of primordial non-Gaussianity through the large-scale nonGaussian halo bias effect was studied.
Journal ArticleDOI
Present bounds on the relativistic energy density in the Universe from cosmological observables
TL;DR: In this article, the relativistic energy density in the universe parameterized in terms of the effective number of neutrinos N using the most recent cosmological data on Cosmic Microwave Background (CMB) temperature anisotropies and polarization, Large Scale galaxy clustering from the Sloan Digital Sky Survey (SDSS) and 2dF, luminosity distances of type Ia Supernovae, Lyman-alpha absorption clouds (Ly-alpha), the Baryonic Acoustic Oscillations (BAO) detected in the Luminous Red Gal
Journal ArticleDOI
Signatures of photon and axion-like particle mixing in the gamma-ray burst jet
TL;DR: In this paper, the authors show that the depletion of photons due to conversion to ALPs changes the linear degree of polarization from the values predicted by the synchrotron model of gamma ray emission.
Journal ArticleDOI
Absolute <mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" display="inline"><mml:mi>ν</mml:mi></mml:math> Mass Measurement with the DUNE Experiment
TL;DR: In this article , the authors derived a new ε-mass sensitivity attainable at the future DUNE far detector from a future supernova collapse in our galactic neighborhood, finding a sub-eV reach under favorable scenarios.
Journal ArticleDOI
Running of featureful primordial power spectra
TL;DR: In this article, the authors show that a primordial power spectrum with localized features could in principle give rise to the observed slow-roll anarchy when fitted to a featureless power spectrum.
