Absence of Correlation between the Solar Neutrino Flux and the Sunspot Number
Solar Neutrino Flux Sunspot Number
2015/8/20
There exists a considerable amount of research claiming a puzzling anticorrelation between the
neutrino detection rate at the Homestake experiment and indicators of solar activity such as the sunspot...
Deep 1.1 mm-wavelength imaging of the GOODS-S field by AzTEC/ASTE - I. Source catalogue and number counts
Source catalogue number counts
2014/12/22
We present the first results from a confusion-limited map of the Great Observatories Origins Deep Survey-South (GOODS-S) taken with the AzTEC camera on the Atacama Submillimeter Telescope Experiment. ...
AzTEC/ASTE 1.1-mm survey of the AKARI Deep Field South: source catalogue and number counts
source catalogue number counts
2014/12/22
We present results of a 1.1-mm deep survey of the AKARI Deep Field South (ADF-S) with AzTEC mounted on the Atacama Submillimetre Telescope Experiment (ASTE). We obtained a map of 0.25-deg2 area with a...
Axino dark matter and baryon number asymmetry from Q-ball decay in gauge mediation
Axino dark matter baryon number asymmetry Q-ball decay gauge mediation
2012/2/21
We investigate the Q-ball decay into the axino dark matter in the gauge-mediated supersymmetry breaking. In our scenario, the Q ball decays mainly into nucleons and partially into axinos to account fo...
Large Variations of the coefficient $J_2$ of geopotential, and the dynamical Love number $k_2^d$ from the analysis of laser ranging to LAGEOS~1 and LAGEOS~2
Earth’s satellites geopotential tides Love numbers
2011/8/24
Secular and seasonal variations of the coefficient $J_2$ of the geopotential are studied from the analysis of laser measurements of distances to the geodetic satellites LAGEOS~1 (1988--2003) and LAGEO...

High Lundquist Number Resistive MHD Simulations of Magnetic Reconnection: Searching for Secondary Island Formation
Lundquist Number Resistive MHD Simulations Magnetic Reconnection
2011/9/9
Recently, secondary island formation due to the tearing instability of the Sweet-Parker current sheet was identified as a possible mechanism that can lead to fast reconnection (less sensitive dependen...
A refined constrain on lepton number from Big Bang Nucleosynthesis
Neutrinos physics of the early universe primordial asymmetries
2010/11/10
We study the evolution of primordial neutrino{antineutrino asymmetries in the early universe, before and during Big Bang Nucleosynthesis (BBN). We consider quite a wide range for the total lepton numb...
Cluster number counts in quintessence models
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/29
Even though the abundance and evolution of clusters have been used to study the cosmological parameters including the properties of dark energy owing to their pure dependence on the geometry of the Un...
Effects of Strong Gravitational Lensing on mm-wave Galaxy Number Counts
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/24
We study the effects of strong lensing on the observed number counts of mm sources using a ray tracing simulation and two number count models of unlensed sources.
AzTEC/ASTE 1.1-mm Survey of the AKARI Deep Field South: source catalogue and number counts
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/23
We present results of a 1.1 mm deep survey of the AKARI Deep Field South (ADF-S) with AzTEC mounted on the Atacama Submillimetre Telescope Experiment (ASTE). We obtained a map of 0.25 sq. deg area wit...
Forming Planetesimals by Gravitational Instability: I. The Role of the Richardson Number in Triggering the Kelvin-Helmholtz Instability
Earth and Planetary Astrophysics (astro-ph.EP)
2010/12/23
Gravitational instability (GI) of a dust-rich layer at the midplane of a gaseous circumstellar disk is one proposed mechanism to form planetesimals, the building blocks of rocky planets and gas giant ...
