Determination of the strong coupling constant from the inclusive jet cross section in ppbar collisions at sqrt(s)=1.96 TeV

D0 Collaboration, V. M. Abazov

We determine the strong coupling constant alphas and its energy dependence from the pT dependence of the inclusive jet cross section in ppbar collisions at sqrt(s)=1.96 TeV. The st…

Effective Field Theory for Quantum Liquid in Dwarf Stars

Gregory Gabadadze, Rachel A. Rosen

An effective field theory approach is used to describe quantum matter at greater-than-atomic but less-than-nuclear densities which are encountered in white dwarf stars. We focus on…

Identification and properties of the photospheric emission in GRB090902B

F. Ryde, M. Axelsson, B. B. Zhang +19

The Fermi Gamma-ray Space Telescope observed the bright and long GRB090902B, lying at a redshift of z = 1.822. Together the Large Area Telescope (LAT) and the Gamma-ray Burst Monit…

Nebular Spectra and Explosion Asymmetry of Type Ia Supernovae

Keiichi Maeda, Stefan Taubenberger, Jesper Sollerman +4

The spectral signatures of asymmetry in Type Ia Supernova (SN Ia) explosions are investigated, using a sample of late-time nebular spectra. First, a kinematical model is constructe…

Where are the trapped surfaces?

Jan E. Aman, Ingemar Bengtsson, José M. M. Senovilla

We discuss the boundary of the spacetime region through each point of which a trapped surface passes, first in some simple soluble examples, and then in the self-similar Vaidya sol…

Fermi observations of Cassiopeia and Cepheus: diffuse gamma-ray emission in the outer Galaxy

LAT collaboration

We present the analysis of the interstellar gamma-ray emission measured by the Fermi Large Area Telescope toward a region in the second Galactic quadrant at 100 deg < l < 145 deg a…
