Simulations of Oscillation Modes of the Solar Convection Zone
D. Georgobiani, A. G. Kosovichev, R. Nigam +2
We use the three-dimensional hydrodynamic code of Stein and Nordlund to realistically simulate the upper layers of the solar convection zone in order to study physical characterist…
Synchrotron Emission as the Source of GRB Spectra, Part II: Observations
Nicole M. Lloyd-Ronning, Vahe' Petrosian, Robert D. Preece
We test the models of synchrotron emission presented in Part I of this series (Lloyd & Petrosian, these proceedings) against the distributions and evolution of GRB spectral paramet…
Synchrotron Radiation as the Source of GRB Spectra, Part I: Theory
Nicole M. Lloyd-Ronning, Vahe' Petrosian
We investigate synchrotron emission models as the source of gamma ray burst spectra. We show that allowing for synchrotron self absorption and a ``smooth cutoff'' to the electron e…
Plasma Turbulence and Stochastic Acceleration in Solar Flares
Vahe Petrosian
Observational aspects of solar flares relevant to the acceleration process of electrons and protons are reviewed and it is shown that most of these observations can be explained by…
The USA X-ray Timing Experiment
P. S. Ray, K. S. Wood, G. Fritz +21
The USA Experiment is a new X-ray timing experiment with large collecting area and microsecond time resolution capable of conducting a broad program of studies of galactic X-ray bi…
The power spectrum of the CfA/SSRS UZC galaxy redshift survey
Nikhil Padmanabhan, Max Tegmark, Andrew J. S. Hamilton
The combined CfA2/SSRS redshift catalog has recently been improved and made public. We compute the redshift-space power spectrum of this catalog using the regions at -2.5 < delta <…
