Fundamental Physics and Relativistic Laboratory Astrophysics with Extreme Power Lasers
Fundamental Physics Relativistic Laboratory Astrophysics Extreme Power Lasers
2012/2/23
The prospects of using extreme relativistic laser-matter interactions for laboratory astrophysics are discussed. Laser-driven process simulation of matter dynamics at ultra-high energy density is prop...
Constraining GRB Emission Physics with Extensive Early-Time, Multiband Follow-up
Constraining Emission Physics Extensive Early-Time Multiband Follow-up
2011/10/10
Understanding the origin and diversity of emission processes responsible for Gamma-ray Bursts (GRBs) remains a pressing challenge. While prompt and contemporaneous panchromatic observations have the p...
Lepton flavor violating New Physics and supernova explosion
Lepton flavor violating New Physics supernova explosion
2011/1/13
Electrons and electron neutrinos in the inner core of the core-collapse supernova are highly degenerate and therefore numerous during a few seconds of explosion. In contrast, leptons of other flavors ...
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...

2010/11/9
The impact of the Fermi Gamma-ray Space Telescope on blazar research is reviewed. This
includes a brief description of the Fermi Large Area Telescope, a summary of the various classes of extragalacti...
Big Bang Nucleosynthesis as a Probe of New Physics
Big bang nucleosynthesis early Universe abundances of light elements ex-tensions of the Standard Model dark matter
2010/11/16
Big bang nucleosynthesis (BBN), an epoch of primordial nuclear transforma-tions in the expanding Universe, has left an observable imprint in the abundances of light elements. Precision observations of...
Understanding the Oldest White Dwarfs: Atmospheres of Cool WDs as Extreme Physics Laboratories
Solar and Stellar Astrophysics (astro-ph.SR) Materials Science (cond-mat.mtrl-sci)
2010/12/27
Reliable modeling of the atmospheres of cool white dwarfs is crucial for understanding the atmospheric evolution of these stars and for accurate white dwarfs cosmochronology. Over the last decade {\it...
