Observations and Analysis of High-Resolution Magnetic Field Structures in Molecular Clouds
Observations Analysis High-Resolution Magnetic Field Structures Molecular Clouds
2012/2/23
Recent high-angular-resolution (up to 0.7") dust polarization observations toward star forming regions are summarized. With the Sub-Millimeter Array, the emission from the dense structures is traced a...
Clustered Star Formation in Magnetic Clouds: Properties of Dense Cores Formed in Outflow-Driven Turbulence
Magnetic Clouds: Properties Dense Cores Formed Outflow-Driven Turbulence
2011/10/11
We investigate the physical properties of dense cores formed in turbulent, magnetized, parsec-scale clumps of molecular clouds, using three-dimensional numerical simulations that include protostellar ...
Magnetic properties of quark matter are discussed in the light of the observation of pulsars. Our works about spontaneous spin polarization and spin density wave are reviewed and their implications on...

2011/9/28
Only for very few beta Cephei stars has the behaviour of the magnetic field been studied over the rotation cycle. During the past two years we have obtained multi-epoch polarimetric spectra of the bet...
Faraday Rotation Measure due to the Intergalactic Magnetic Field II: the Cosmological Contribution
Intergalactic Magnetic Field II Cosmological Contribution
2011/9/26
We investigate the Faraday rotation measure (RM) due to the intergalactic magnetic field (IGMF) through the cosmic web up to cosmological distances, using a model IGMF based on turbulence dynamo in th...
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...
The Effect of Magnetic Turbulence Energy Spectra and Pickup Ions on the Heating of the Solar Wind
Pickup ions, Solar wind heating, MHD turbulence, Wave-particle interaction
2011/9/9
In recent years, a phenomenological solar wind heating model based on a turbulent energy cascade prescribed by the Kolmogorov theory has produced reasonably good agreement with observations on proton ...
New Constraints on the Primordial Magnetic Field
primordial magnetic field numerical analysis
2010/3/19
We present the newest statistical and numerical analysis of the matter and cosmic microwave background power spectrum with effects of the primordial magnetic field (PMF) included. New limits to the PM...
SGRs and AXPs：Evidence for Delayed Amplification of Magnetic Field after Neutron Star Formation?
Anomalous X-ray Pulsars soft gamma-ray repeaters supernova remnants
2009/9/4
We present new analysis of the birth rate of AXPs and SGRS and their associated SNRs. Using Kolmogorov-Smirnov statistics together with parametric fits based on a robust estimator, we find a birth rat...
