Looking for Axion Dark Matter in Dwarf Spheroidals

Andrea Caputo, Carlos Peña Garay, Samuel J. Witte

We study the extent to which the decay of cold dark matter axions can be probed with forthcoming radio telescopes such as the Square Kilometer Array (SKA). In particular we focus o…

Strong Bayesian Evidence for the Normal Neutrino Hierarchy

Fergus Simpson, Raul Jimenez, Carlos Pena-Garay +1

The configuration of the three neutrino masses can take two forms, known as the normal and inverted hierarchies. We compute the Bayesian evidence associated with these two hierarch…

Hiding neutrino mass in modified gravity cosmologies

Nicola Bellomo, Emilio Bellini, Bin Hu +3

Cosmological observables show a dependence with the neutrino mass, which is partially degenerate with parameters of extended models of gravity. We study and explore this degeneracy…

Dark energy from the motions of neutrinos

Fergus Simpson, Raul Jimenez, Carlos Pena-Garay +1

We demonstrate that a scalar field is unable to reverse its direction of motion while continuously exchanging energy with another fluid. If the rate of transfer is modulated by the…

Neutrino footprint in Large Scale Structure

Raul Jimenez, Carlos Pena-Garay, Licia Verde

Recent constrains on the sum of neutrino masses inferred by analyzing cosmological data, show that detecting a non-zero neutrino mass is within reach of forthcoming cosmological su…

Results from the first use of low radioactivity argon in a dark matter search

The DarkSide Collaboration, P. Agnes, L. Agostino +158

Liquid argon is a bright scintillator with potent particle identification properties, making it an attractive target for direct-detection dark matter searches. The DarkSide-50 dark…

The case for a directional dark matter detector and the status of current experimental efforts

S. Ahlen, N. Afshordi, J. B. R. Battat +109

We present the case for a dark matter detector with directional sensitivity. This document was developed at the 2009 CYGNUS workshop on directional dark matter detection, and conta…
