Synchrotron spectra of GRB prompt emission and pulsar wind nebulae
Siyao Xu
Particle acceleration is a fundamental process in many high-energy astrophysical environments and determines the spectral features of their synchrotron emission. We have studied th…
Direct Detection of Black Hole-Driven Turbulence in the Centers of Galaxy Clusters
Yuan Li, Marie-Lou Gendron-Marsolais, Irina Zhuravleva +16
Supermassive black holes (SMBHs) are thought to provide energy that prevents catastrophic cooling in the centers of massive galaxies and galaxy clusters. However, it remains unclea…
Cosmic ray transport in starburst galaxies
Mark R. Krumholz, Roland M. Crocker, Siyao Xu +3
Starburst galaxies are efficient -ray producers, because their high supernova rates generate copious cosmic ray (CR) protons, and their high gas densities act as thick targets o…
Projected velocity statistics of interstellar turbulence
Siyao Xu
Velocity statistics is a direct probe of the dynamics of interstellar turbulence. Its observational measurements are very challenging due to the convolution between density and vel…
PICO: Probe of Inflation and Cosmic Origins
S. Hanany, M. Alvarez, E. Artis +79
The Probe of Inflation and Cosmic Origins (PICO) is a proposed probe-scale space mission consisting of an imaging polarimeter operating in frequency bands between 20 and 800 GHz. W…
On the formation of density filaments in the turbulent interstellar medium
Siyao Xu, Suoqing Ji, A. Lazarian
This study is motivated by recent observations on ubiquitous interstellar density filaments and guided by modern theories of compressible magnetohydrodynamic (MHD) turbulence. The…
Studying Magnetic Fields in Star Formation and the Turbulent Interstellar Medium
Laura Fissel, Charles L. H. Hull, Susan E. Clark +10
Understanding the physics of how stars form is a highly-prioritized goal of modern Astrophysics, in part because star formation is linked to both galactic dynamics on large scales…
PICO: Probe of Inflation and Cosmic Origins
Shaul Hanany, Marcelo Alvarez, Emmanuel Artis +79
The Probe of Inflation and Cosmic Origins (PICO) is an imaging polarimeter that will scan the sky for 5 years in 21 frequency bands spread between 21 and 799 GHz. It will produce f…
Turbulent dynamo in a weakly ionized medium
Siyao Xu, Sudip K. Garain, Dinshaw S. Balsara +1
The small-scale turbulent dynamo is an important process contributing to the cosmic magnetization. In partially ionized astrophysical plasmas, the dynamo growth of magnetic energy…
