Alignment of Dust by Radiative Torque: Recent Developments
A. Lazarian, Thiem Hoang
Alignment of dust by radiative torques (RATs) has proven to be the most promising mechanism to explain alignment in various astrophysical environments, from comet atmospheres to ac…
Model of Reconnection of Weakly Stochastic Magnetic Field and its Testing
A. Lazarian, E. Vishniac, G. Kowal
Astrophysical fluids are generically turbulent, which means that frozen-in magnetic fields are, at least, weakly stochastic. Therefore realistic studies of astrophysical magnetic r…
Model of Reconnection of Weakly Stochastic Magnetic Field and its Implications
A. Lazarian, E. Vishniac
We discuss the model of magnetic field reconnection in the presence of turbulence introduced by us approximately ten years ago. The model does not require any plasma effects to be…
Statistics of Galactic Synchrotron and Dust Foregrounds: Spectra, PDFs and Higher-Order Moments
Jungyeon Cho, A. Lazarian
We present statistical analysis of diffuse Galactic synchrotron emission and polarized thermal emission from dust. Both Galactic synchrotron emission and polarized thermal emission…
Grain Alignment by Radiative Torques
A. Lazarian
Grain alignment is a notoriously difficult problem, that is extremely rich in underlying physics. The long history of attempts theoretical handling of the problem resulted in rathe…
Alignment of Dust with Magnetic Inclusions: Radiative Torques and Superparamagnetic Barnett and Nuclear Relaxation
A. Lazarian, T. Hoang
We consider grains with superparamagnetic inclusions and report two new condensed matter effects that can enhance the internal relaxation of the energy of a wobbling grain, namely,…
