3-D Galaxy-mapping Project Construction Phase
2016/8/11
A 3-D sky-mapping project that will measure the light of millions of galaxies has received formal approval from the U.S. Department of Energy to move forward with construction. Installation of the pro...
DETECTION OF STRONG MILLIMETER EMISSION FROM THE CIRCUMSTELLAR DUST DISK AROUND V1094 SCO: COLD AND MASSIVE DISK AROUND A T TAURI STAR IN A QUIESCENT ACCRETION PHASE?
spectral energy compact dust emission
2014/12/20
We present the discovery of a cold massive dust disk around the T Tauri star V1094 Sco in the Lupus molecular cloud from the 1.1 mm continuum observations with AzTEC on ASTE. A compact (r 320 AU) cont...
Effect of Ion Dynamics on the Evolution of Electron Phase-space Holes
Ion dynamics Electron holes Transverse instability Magnetized plasma
2013/10/3
The evolution of two-dimensional (2D) electron phase-space holes (electron holes) has been previously investigated with electrostatic Particle-in-Cell (PIC) simulations, which neglect ion dynamics. Th...
Simulating the Common Envelope Phase of a Red Giant Using SPH and Uniform Grid Codes
Simulating Common Envelope Phase Red Giant Using SPH Uniform Grid Codes
2011/10/21
We use three-dimensional hydrodynamical simulations to study the rapid infall phase of the common envelope interaction of a red giant branch star of mass equal to 0.88 \msun and a companion star of ma...
Enhancement of nuclear pasta formation due to multi-nucleus simultaneous collision is presented based on time-dependent density functional calculations with periodic boundary condition. This calculati...
Two phase, inward-then-outward migration of Jupiter and Saturn in the gaseous Solar Nebula
accretion, accretion disks – planets and satellites: formation – hydrodynamics – methods: numerical
2011/10/20
It has recently been shown that the terrestrial planets and asteroid belt can be reproduced if the giant planets underwent an inward-then-outward migration (the "Grand Tack"; Walsh et al 2011). Inward...
Strong Electroweak Phase Transitions in the Standard Model with a Singlet
Strong Electroweak Phase Transitions Standard Model Singlet
2011/10/14
It is well known that the electroweak phase transition (EWPhT) in extensions of the Standard Model with one real scalar singlet can be first-order for realistic values of the Higgs mass. We revisit th...
Magnetic Fields at First Order Phase Transition: A Threat to Electroweak Baryogenesis
Magnetic Fields First Order Phase Transition:Electroweak Baryogenesis
2011/10/17
The generation of the observed baryon asymmetry may have taken place during the electroweak phase transition, thus involving physics testable at LHC, a scenario dubbed electroweak baryogenesis. In thi...
An AMR Study of the Common Envelope Phase of Binary Evolution
AMR Study Common Envelope Phase Binary Evolution
2011/10/12
The hydrodynamic evolution of the common envelope phase of a low mass binary composed of a 1.05 Msun red giant and a 0.6 Msun companion has been followed for five orbits of the system using a high res...
