Radio observations of comet 9P/Tempel 1 before and after Deep Impact
N. Biver, D. Bockelée-Morvan, J. Boissier +14
Comet 9P/Tempel 1 was the target of a multi-wavelength worldwide investigation in 2005. The NASA Deep Impact mission reached the comet on 4.24 July 2005, delivering a 370 kg impact…
The Polarizing Power of the Interstellar Medium in Taurus
Hector G. Arce, Alyssa A. Goodman, Pierre Bastien +2
We present a study of the polarizing power of the dust in cold dense regions (dark clouds) compared to that of dust in the general interstellar medium (ISM). Our study uses new pol…
Gamma-Ray Burst and Relativistic Shells: The Surface Filling Factor
E. E. Fenimore, C. Cooper, E. Ramirez-Ruiz +3
The variability observed in many complex gamma-ray bursts (GRBs) is inconsistent with causally connected variations in a single, symmetric, relativistic shell interacting with the…
Kinematic Arguments Against Single Relativistic Shell Models for Gamma-Ray Bursts
E. E. Fenimore, E. Ramirez, M. C. Sumner
Two main types of models have been suggested to explain the long durations and multiple peaks of Gamma-Ray Bursts (GRBs). In one, there is a very quick release of energy at a centr…
Variability in Shell Models of Gamma-Ray Bursts
M. C. Sumner, E. E. Fenimore
Many cosmological models of gamma-ray bursts (GRBs) assume that a single relativistic shell carries kinetic energy away from the source and later converts it into gamma rays, perha…
Relativistic Shells and Gamma-Ray Bursts
E. E. Fenimore, M. C. Sumner
In many models of Gamma-Ray Bursts (GRBs) relativistic shells are responsible for the overall envelope of emission. We use kinematics and symmetry to calculate the time history and…
