Luminescence of water or ice as a new detection method for magnetic monopoles

EPJ Web of Conferences, 2017
Cosmic ray detectors use air as a radiator for luminescence. In water and ice, Cherenkov light is the dominant light producing mechanism when the particle’s velocity exceeds the Cherenkov threshold, approximately three quarters of the speed of light in ...

Observationally Determining the Properties of Dark Matter [PDF]

, 1998
Determining the properties of the dark components of the universe remains one of the outstanding challenges in cosmology. We explore how upcoming CMB anisotropy measurements, galaxy power spectrum data, and supernova (SN) distance measurements can ...

Birth Kick Distributions and the Spin-Kick Correlation of Young Pulsars [PDF]

, 2007
Evidence from pulsar wind nebula symmetry axes and radio polarization observations suggests that pulsar motions correlate with the spin directions.

Solar Neutrinos [PDF]

, 2012
The study of solar neutrinos has given since ever a fundamental contribution both to astroparticle and to elementary particle physics, offering an ideal test of solar models and offering at the same time relevant indications on the fundamental ...

Neutrino Velocity and the Variability of Fundamental Constants

, 2012
Neutrino speed experiments could be viewed not only as tests of Lorentz invariance but also as measurements of limiting propagation speed for all standard model species below certain depth where no direct metrological information is available. The latter

Solar Neutrinos: Status and Prospects

, 2012
We describe the current status of solar neutrino measurements and of the theory -- both neutrino physics and solar astrophysics -- employed in interpreting measurements.

Planetary influence on the young Sun's evolution: the solar neutrino probe

, 2013
Recent observations of solar twin stars with planetary systems like the Sun, have uncovered that these present a peculiar surface chemical composition. This is believed to be related to the formation of earth-like planets.

10,000 Standard Solar Models: a Monte Carlo Simulation

, 2005
We have evolved 10,000 solar models using 21 input parameters that are randomly drawn for each model from separate probability distributions for every parameter.

Superluminal neutrinos in long baseline experiments and SN1987a [PDF]

, 2011
Precise tests of Lorentz invariance in neutrinos can be performed using long baseline experiments such as MINOS and OPERA or neutrinos from astrophysical sources. The MINOS collaboration reported a measurement of the muonic neutrino velocities that hints

Impairments on the Construction of a Cosmic Neutrino Detector in a Romanian Salt Mine

Natural Sciences, EarlyView.
The modulus of the transfer function of an antenna when boreholed in salt. With red are represented results from the Targu Ocna salt mine and with black‐from Slanic salt mine ABSTRACT Indirect cosmic neutrino detectors utilize dense media to enhance the likelihood of neutrino interactions within the detection volume.
