The Physics of Disk Winds, Jets,and X-ray Variability in GRS 1915+105
Disk Winds Jets X-ray Variability
2011/1/11
We present new insights about accretion and ejection physics based on joint RXTE/Chandra HETGS studies of rapid X-ray variability in GRS 1915+105. For the first time, with fast phase-resolved spectros...
Tilted Physics: A Cosmologically Dipole-Modulated Sky
Tilted Physics Cosmologically Dipole-Modulated Sky
2010/11/15
Physical constants and cosmological parameters could vary with position. On the largest scales
such variations would manifest themselves as gradients across our Hubble volume, leading to dipole-modul...
Ultraviolet Coronagraph Spectroscopy: A Key Capability for Understanding the Physics of Solar Wind Acceleration
Ultraviolet Coronagraph Spectroscopy Physics of Solar Wind Acceleration
2010/11/15
Understanding the physical processes responsible for accelerating the solar wind requires detailed measurements of the collisionless plasma in the extended solar corona. Some key clues about these pro...
Recent results from the CoGeNT collaboration (as well as the annual modulation reported by
DAMA/LIBRA) point toward dark matter with a light (5 10 GeV) mass and a relatively large
elastic...
In this article we give a brief review of the fundamental physics that can be done with the future space-based gravitational wave detector LISA. This includes detection of gravitational wave bursts co...
