Dark stars and boosted dark matter annihilation rates
(IOP Publishing, 2011)
Dark stars (DSs) may constitute the first phase of stellar evolution, powered by dark matter (DM) annihilation. We investigate here the properties of DSs, assuming that the DM particle has the properties required for ...
Mapping of femtosecond laser-induced collateral damage by electron backscatter diffraction
(The American Institute of Physics, 2011-10-15)
Thermal analysis of high intensity organic light-emitting diodes based on a transmission matrix approach
(The American Institute of Physics, 2011-12-15)
Phase transition and structure of silver azide at high pressure
(The American Institute of Physics, 2011)
A Si-micromachined 48-stage Knudsen pump for on-chip vacuum
(IOP Publishing, 2012)
This paper describes a thermal transpiration-driven multistage Knudsen pump for vacuum pumping applications. This type of pump relies upon the motion of gas molecules from the cold end to the hot end of a channel in which ...
Effects of continuum breakdown on hypersonic aerothermodynamics for reacting flow
(The American Institute of Physics, 2011-02)
ACE/SWICS Observations of Heavy Ion Dropouts within the Solar Wind
(IOP Publishing, 2012)
We present the first in situ observations of heavy ion dropouts within the slow solar wind, observed for select elements ranging from helium to iron. For iron, these dropouts manifest themselves as depletions of the Fe/H ...
A Chandra Survey of Supermassive Black Holes with Dynamical Mass Measurements
(IOP Publishing, 2012)
We present Chandra observations of 12 galaxies that contain supermassive black holes (SMBHs) with dynamical mass measurements. Each galaxy was observed for 30 ks and resulted in a total of 68 point-source detections in the ...
