Power of a Turbulent Pulsar
Andrei Gruzinov
We speculate that stationary force-free pulsar magnetospheres are screw unstable, and the spin-down power of real pulsars is carried by turbulent Poynting jets. The turbulent jet e…
Dark Energy with w>-4/3
Andrei Gruzinov
Acceleration of the universe might be driven by a continuous elastic medium -- elastic dark energy (Bucher and Spergel 1999). Elastic dark energy can stably support equations of st…
Three Form Inflation
Andrei Gruzinov
It is noted that inflation driven by a three form with arbitrary self coupling satisfies a consistency relation , between spectral indices of scalar and tensor cosmolog…
Post-Inflationary Curvature Perturbations
Andrei Gruzinov
Curvature perturbations generated after the end of inflation are estimated for a generic multi-field inflationary potential. The curvature perturbations are generated by conversion…
Non-Gaussianity of Large-Scale Cosmological Perturbations
Andrei Gruzinov
Perturbations in a universe with matter and cosmological constant are computed in terms of the primordial scalar perturbation up to second order. The calculation is easy -- a gener…
Self-similarity of the Third Type in the Strong Explosion Problem
Andrei Gruzinov
Propagation of a blast wave due to strong explosion in the center of a power-law-density () spherically symmetric atmosphere is studied. For adiabatic index of 5/3…
