The Effect of Bound Dineutrons upon BBN
James P. Kneller, Gail C. McLaughlin
We have examined the effects of a bound dineutron, n2, upon big bang nucleosynthesis (BBN) as a function of its binding energy B_n2. We find a weakly bound dineutron has little imp…
Separating Thermal and Non-Thermal X-Rays in Supernova Remnants II: Spatially Resolved Fits to SN1006 AD
K. K. Dyer, S. P. Reynolds, K. J. Borkowski
We present a spatially resolved spectral analysis of full ASCA observations of the remnant of the supernova of 1006 AD. This remnant shows both nonthermal X-ray emission from brigh…
A High-Resolution Study of Nonthermal Radio and X-Ray Emission from SNR G347.3-0.5
J. S. Lazendic, P. O. Slane, B. M. Gaensler +3
G347.3-0.5 is one of three shell-type supernova remnants in the Galaxy whose X-ray spectrum is dominated by nonthermal emission. This puts G347.3-0.5 in the small, but growing clas…
The Effect of Magnetic Field Tilt and Divergence on the Mass Flux and Flow Speed in a Line-Driven Stellar Wind
Stan Owocki, Asif ud-Doula
We carry out an extended analytic study of how the tilt and faster-than-radial expansion from a magnetic field affect the mass flux and flow speed of a line-driven stellar wind. A…
On the Contribution of Gamma Ray Bursts to the Galactic Inventory of Some Intermediate Mass Nuclei
Jason Pruet, Rebecca Surman, Gail C. McLaughlin
Light curves from a growing number of Gamma Ray Bursts (GRBs) indicate that GRBs copiously produce radioactive Ni moving outward at fractions of the speed of light. We calculate nu…
Hydrodynamic Simulation of Supernova Remnants Including Efficient Particle Acceleration
Donald C. Ellison, Anne Decourchelle, Jean Ballet
A number of supernova remnants (SNRs) show nonthermal X-rays assumed to be synchrotron emission from shock accelerated TeV electrons. The existence of these TeV electrons strongly…
Microphysics of Shock Acceleration from Observations of X-Ray Synchrotron Emission from Supernova Remnants
S. P. Reynolds
Recent observations of non-thermal X-rays from supernova remnants have been attributed to synchrotron radiation from the loss-steepened tail of a non-thermal distribution of electr…
Neutrinos and Nucleosynthesis in Gamma-Ray Burst Accretion Disks
R. Surman, G. C. McLaughlin
We calculate the nuclear composition of matter in accretion disks surrounding stellar mass black holes as are thought to accompany gamma-ray bursts (GRBs). We follow a mass element…
Magnetohydrodynamic Jump Conditions for Oblique Relativistic Shocks with Gyrotropic Pressure
Glen P. Double, Matthew G. Baring, Frank C. Jones +1
Shock jump conditions are obtained for steady-state, plane shocks with oblique magnetic fields and arbitrary flow speeds. For ultrarelativistic and nonrelativistic shocks, the jump…
Discovery of a New Pulsar Wind Nebula in the Large Magellanic Cloud
B. M. Gaensler, S. P. Hendrick, S. P. Reynolds +1
We present new high-resolution radio and X-ray observations of the supernova remnant (SNR) B0453-685 in the Large Magellanic Cloud, carried out with the Australia Telescope Compact…
Thermal X-ray emission from shocked ejecta in Type Ia Supernova Remnants. Prospects for explosion mechanism identification
Carles Badenes, Eduardo Bravo, Kazimierz J. Borkowski +1
The explosion mechanism behind Type Ia supernovae is a matter of continuing debate. The diverse attempts to identify or at least constrain the physical processes involved in the ex…
Spherically symmetric relativistic MHD simulations of pulsar wind nebulae in supernova remnants
N. Bucciantini, J. M. Blondin, L. Del Zanna +1
Pulsars, formed during supernova explosions, are known to be sources of relativistic magnetized winds whose interaction with the expanding supernova remnants (SNRs) gives rise to a…
Near-Infrared Synchrotron Emission from Cas A
Jeonghee Rho, Stephen P. Reynolds, William T. Reach +2
High energy observations of Cas A suggested the presence of synchrotron radiation, implying acceleration of cosmic rays by young supernova remnants. We detect synchrotron emission…
Inverse Power Law Quintessence with Non-Tracking Initial Conditions
James P. Kneller, Louis E. Strigari
A common property of popular models of quintessence dark energy is the convergence to a common solution from a large range of the initial conditions. We re-examine the popular inve…
Molar mass estimate of dark matter from the dark mass distribution measurements
Yuriy Mishchenko, Chueng-Ryong Ji
We study the distribution of dark matter versus visible matter using a set of data obtained from strong gravitational lensing in the galaxy cluster CL0024+1654 and another set of d…
