The conservative cascade of kinetic energy in compressible turbulence
hydrodynamics methods: numerical turbulence
2011/10/14
The physical nature of compressible turbulence is of fundamental importance in a variety of astrophysical settings. We present the first direct evidence that mean kinetic energy cascades conservativel...
Photon noise limited radiation detection with lens-antenna coupled Microwave Kinetic Inductance Detectors
Photon noise limited radiation Microwave Kinetic Inductance Detectors
2011/10/13
Microwave Kinetic Inductance Detectors (MKIDs) have shown great potential for sub-mm instrumentation because of the high scalability of the technology. Here we demonstrate for the first time in the su...

Large Scale Structures Kinetic Gravity Braiding Model
2010/11/12
We study cosmological consequences of a kinetic braiding model, which is proposed as an alternative to the dark energy model. The kinetic braiding model we study is characterised by a parameter n, whi...
Dark matter and a new gauge boson through kinetic mixing
Hidden gauge symmetry Kinetic mixing Thermal dark matter
2010/11/16
We consider a hidden sector model of dark matter which is charged under a hidden U(1)X gauge symmetry. Kinetic mixing of U(1)X with the Standard Model hypercharge U(1)Y is allowed to provide communica...
An extension of gas-kinetic BGK Navier-Stokes scheme to multidimensional astrophysical magnetohydrodynamics
Instrumentation and Methods for Astrophysics (astro-ph.IM)
2011/1/7
The multidimensional gas-kinetic scheme for the Navier-Stokes equations under gravitational fields [J. Comput. Phys. 226 (2007) 2003-2027] is extended to resistive magnetic flows. The non-magnetic par...
