Recently there has been some progress in modeling the statistical properties of turbulent flows using simple superstatistical models. Here we briefly review the concept of superstatistics in turbulence. In particular, we discuss a superstatistical extension of the Sawford model and compare with experimental data.

In this paper we analyze the structural parameters of the dwarf galaxies in the Coma Cluster with -18

Two-dimensional maps of the stellar and gas kinematics of the bar and starbursting circumnuclear region in the barred spiral galaxy M100 are presented. In this progress report, we present maps of the total intensity, mean velocity and velocity dispersion for the stars and the gas. The gas velocity field shows significant kinematic signatures of gas

We study long-term evolution of stellar bars in disk galaxies embedded in live dark matter halos. Using numerical modeling with N = 1.2 × 106 particles, we find that this evolution proceeds through recurrent dynamical instabilities and associated secular changes. We have studied the vertical buckling instability in the bar and find that it shortens

Optical photometry of HIDEEP galaxies was carried out using a combination of SExtractor (Bertins & Arnouts, 1996A&AS..117..393B) and the STSDAS package in IRAF, where the ellipse task was used to obtain radial surface brightness profiles. (2 data files).
