Yen-Jie Lee probes particle collision data for clues to the universe’s origins（图）
粒子碰撞数据 宇宙起源 粒子物理学
2023/6/9
When Yen-Jie Lee came to MIT as a graduate student in 2006, it was a bit of a culture shock. The aspiring particle physicist had studied physics at National Taiwan University before his career took a ...
Star formation and feedback in smoothed particle hydrodynamic simulations - I. Isolated galaxies
star formation supernova feedback
2014/12/24
We present an analysis of star formation and feedback recipes appropriate for galactic smoothed particle hydrodynamics simulations. Using an isolated Milky Way-like galaxy, we constrain these recipes ...
The growth of central and satellite galaxies in cosmological smoothed particle hydrodynamics simulations
theory formation
2014/12/23
We examine the accretion and merger histories of central and satellite galaxies in a smoothed particle hydrodynamics (SPH) cosmological simulation that resolves galaxies down to 7 × 109 M⊙. Most frien...
Testing Subhalo Abundance Matching in Cosmological Smoothed Particle Hydrodynamics Simulations
galaxies satellite galaxies
2014/12/22
Subhalo abundance matching (SHAM) is a technique for populating simulated dark matter distributions with galaxies, assuming a monotonic relation between a galaxy's stellar mass or luminosity and the m...
A Density Independent Formulation of Smoothed Particle Hydrodynamics
Density Independent Formulation Smoothed Particle Hydrodynamics Cosmology and Extragalactic Astrophysics
2012/2/21
In the standard formulation of the smoothed particle hydrodynamics (SPH), it is assumed that the local density distribution is differentiable. This assumption is used to derive the spatial derivatives...
Effect of Particle Acceleration Process on the Flare Characteristics of Blazars
kinetic equation approach X-ray region
2009/5/19
Following the kinetic equation approach, we study the flare
processes in blazars in the optical-to-X-ray region, considering energy
dependent acceleration time-scale of electrons and synchrotron and...
Is the Cosmological Particle Production Homogeneous?
a cosmological scenario particle production the gravitational field
2010/10/18
Using a gauge-invariant formalism we find the density contrast equation in a cosmological scenario with particle production at the expenses of the gravitational field (open system cosmology). First, w...
