We have obtained high angular resolution, high signal-to-noise spectra of the Calcium triplet absorption lines on the photometric axes of the stellar spheroid in the polar disk galaxy NGC 4650A. Along the major axis, the observed rotation and velocity dispersion measurements show the presence of a kinematically de-coupled nucleus, and a flat velocity(More)
Context. Systems of shells and polar rings in early-type galaxies are considered " bona fide " tracers of mass accretion and/or mergers. Their high frequency in low density environments suggests that such episodes could drive the evolution of at least a fraction of the early-type galaxy population. Aims. We aim to cast light on the star formation histories(More)
We present results of our investigation of two multi-spin galaxies which were taken from the catalog of polar ring galaxies. All of them possess nucleus-like knots. An analysis of gas and stars kinematics and study of the stellar population were carried out for these objects. A complex structure and peculiar kinematics of both components were revealed. The(More)
An expert system has been developed which converts a description of transistor connectivity into a parameterized CMOS module. PAMS was designed to augment a standard cell environment by automatically generating special purpose modules parameterized in terms of area, speed, and power dissipation. Allowing parameterization differentiates PAMS from previous(More)
1 The aim of this work was to investigate the existence of kinematical anomalies in the brightest group member, NGC4778 in order to constrain the dynamical status and the formation history of the group. We used long-slit spectra obtained with FORS1 at VLT, to measure line-of-sight velocity distributions by means of the Fourier Correlation Quotient method,(More)
