Project Icarus: A Review of Local Interstellar Medium Properties of Relevance for Space Missions to the Nearest Stars
Project Icarus Local Interstellar Medium Properties
2011/1/10
I review those properties of the interstellar medium within 15 light-years of the Sun which will be relevant for the planning of future rapid ($v /ge 0.1c$) interstellar space missions to the nearest ...
Fermi Gamma-ray Space Telescope: High-Energy Results from the First Year
Fermi Gamma-ray Space Telescope High-Energy Results
2010/11/9
The Fermi Gamma-ray Space Telescope (Fermi) was launched on June 11, 2008 and began its
first year sky survey on August 11, 2008. The Large Area Telescope (LAT), a wide field-ofview
pair-conversion ...
Hubble Space Telescope Imaging and Spectral Analysis of Two Brown Dwarf Binaries at the L Dwarf/T Dwarf Transition

2010/11/10
We present a detailed examination of the brown dwarf multiples 2MASS J08503593+1057156 and
2MASS J17281150+3948593, both suspected of harboring components that straddle the L dwarf/T
dwarf transitio...
The Space Interferometry Mission Astrometric Grid Giant-Star Survey. III. Basic Stellar Parameters for an Extended Sample
stars abundances fundamental parameters atmospheres latetype rotation
2010/11/10
We present results of high resolution ( 55000) spectral observations of 830 photometrically pre-selected candidate red giants in the magnitude range of V = 9-12. We develop a pipeline for automated d...
We apply the nonstandard loop quantum cosmology method to quan-tize a flat FRW cosmological model with a free scalar field and the cosmological constant Λ > 0. Modification of the Hamiltonian in terms...
Dark energy constraints from a space-based supernova survey
Cosmology and Extragalactic Astrophysics (astro-ph.CO)
2010/12/23
We present a forecast of dark energy constraints that could be obtained from a large sample of distances to Type Ia supernovae detected and measured from space. We simulate the supernova events as the...
