Particle Acceleration in Magnetized Shear-Driven Turbulence
Mingxuan Liu, Mateusz Ruszkowski, Ellen Zweibel +5
Shear flows, ubiquitous in space and astrophysical plasmas, can accelerate particles through turbulence excited by the Kelvin-Helmholtz instability. We present the first numerical…
Observational Signatures of the First Luminous Objects
Siang Peng Oh
The next generation of astronomical instruments will be able to detect dense pockets of ionized gas created by the first luminous objects. The integrated free-free emission from io…
Clustering of Ionizing Sources
Siang Peng Oh
Using existing models for the evolution of clustering we show that the first sources are likely to be highly biased and thus strongly clustered. We compute intensity fluctuations f…
An Efficient Technique to Determine the Power Spectrum from Cosmic Microwave Background Sky Maps
Siang Peng Oh, David N. Spergel, Gary Hinshaw
There is enormous potential to advance cosmology from statistical characterizations of cosmic microwave background sky maps. The angular power spectrum of the microwave anisotropy…
Fast Tides in Slow Stars: the Efficiency of Eddy Viscosity
Jeremy Goodman, Siang Peng Oh
The turbulent viscosity of convection is believed to circularize the orbits of close binary stars. When the tidal period is shorter than the turnover time of the largest eddies, tu…
Searching for the Kinematical Signature of a Black Hole in M87
David Merritt, Siang Peng Oh
Many theories for the formation of massive black holes in galactic nuclei predict that the stellar motions should be anisotropic within the radius of influence of the black hole. W…
