Asymptotic analysis of the Skyrmed monopole
Y. Brihaye, J. Burzlaff, D. H. Tchrakian
We consider a variant of the Georgi Glashow model in the BPS limit, augmented by a higher derivative Skyrme-like term, which is the simplest YMH model that can support monopole bou…
Primordial Mass Segregation in Starburst Stellar Clusters
Sami Dib, Mohsen Shadmehri, Maheswar Gopinathan +2
We present a model to explain the mass segregation and shallow mass functions observed in the central parts of dense and young starburst stellar clusters. The model assumes that th…
Dynamics of charged dust particles in protoplanetary discs
Mohsen Shadmehri
We study the effect of an imposed magnetic field on the motion of charged dust particles in magnetically active regions of a protoplanetary disc. Assuming a power law structure for…
On the Caudrey-Beals-Coifman System and the Gauge Group Action
Georgi G. Grahovski, Marissa Condon
The generalized Zakharov-Shabat systems with complex-valued Cartan elements and the systems studied by Caudrey, Beals and Coifman (CBC systems) and their gauge equivalent are studi…
MARCOS, a numerical tool for the simulation of multiple time-dependent non-linear diffusive shock acceleration
Gilles Ferrand, Turlough Downes, Alexandre Marcowith
We present a new code aimed at the simulation of diffusive shock acceleration (DSA), and discuss various test cases which demonstrate its ability to study DSA in its full time-depe…
The afterglow onset for GRB060418 and GRB060607A
S. Covino, S. D. Vergani, D. Malesani +32
Gamma-ray burst are thought to be produced by highly relativistic outflows. Although upper and lower limits for the outflow initial Lorentz factor are available, observationa…
