Ultra-Relativistic Shocks and the Spectra of Relativistic Fireballs
We examine Fermi-type acceleration at relativistic shocks, and distinguish between the initial boost of the first shock crossing cycle, where the energy gain per particle can be very large, and the Fermi process proper with repeated shock crossings, in which the typical energy gain is of order unity. We calculate by means of numerical simulations the spectrum and angular distribution of particl...
متن کاملEmission and Structure of Compact Fireballs
The possibility that the peak of the spectral energy distribution (SED) of prompt GRB emission is produced on compact scales, prior to the acceleration of the fireball to its terminal Lorentz factor is considered. It is argued that if dissipation on these scales is associated with pair creation processes, then the observed clustering of SED peaks can be accounted for quite naturally by this mec...
متن کاملRadiation from collision-dominated relativistic pair fireballs
It is generally accepted that gamma-ray bursts (GRBs) are initiated by a relativistic pair fireball, converting its internal energy into kinetic energy of a relativistically moving plasmoid and subsequently into radiation. Here, we investigate the early stages of this evolution, after the pair fireball has become optically thin to γγ pair production. We show that for a short period of time, ∼ 0...
متن کاملlanguage learning strategies and vocabulary size of iranian efl learners
learning a second or foreign language requires the manipulation of four main skills, namely, listening, reading, speaking, and writing which lead to effective communication. it is obvious that vocabulary is an indispensible part of any communication, so without a vocabulary, no meaningful communication can take place and meaningful communication relies heavily on vocabulary. one fundamental fac...
Monopole gravitational waves from relativistic fireballs driving gamma-ray bursts
Einstein’s General Relativity predicts that pressure, in general stresses, play a similar role to energy density, ǫ = ρc (with ρ being corresponding mass density), in generating gravity. The source of gravitational field, the active gravitational mass density, sometimes referred to as Whittaker’s mass density, is ρgrav = ρ + 3p/c , where p is pressure in the case of an ideal fluid. Whittaker’s ...
