We present new magnitudes derived from 1.65 µm images for 23 galaxies in the Ursa Major cluster. Magnitudes now exist for all but one spiral meeting our criteria for cluster membership and having H i velocity width greater than 187 km s −1 and inclination greater than 45 •. These spirals fit a Tully-Fisher relation with dispersion in intrinsic magnitudes (after known observational uncertainties...

We study the mode and dispersion properties of graphene-dielectric nonlinear plasmonic waveguide considering the dual nonlinearity of dielectric and graphene. For TM polarization, the mode distribution, the permittivity distribution, and dispersion relation were obtained by numerically solving the Maxwell equations. Compared with the case considering only the nonlinearity of dielectric, the ini...

Recently the CO line width (FWHM(CO)) has been suggested to be a surro-gate of the bulge velocity dispersion (σ) of the host galaxies of high redshift quasars, and the black hole – bulge (M BH − σ) relation obtained with this assumption departs significantly from the M BH − σ relation in the local universe. In this study we first present an investigation on the correlation between the CO line w...

We present an analysis of the color-magnitude-velocity dispersion relation for a sample of 39320 earlytype galaxies within the Sloan Digital Sky Survey. We demonstrate that the color-magnitude relation is entirely a consequence of the fact that both the luminosities and colors of these galaxies are correlated with stellar velocity dispersions. Previous studies of the color-magnitude relation ov...

Recently, it has been suggested that the CO line width (FWHM(CO)) is a surrogate for the bulge velocity dispersion (σ) of the host galaxies of high-redshift quasars, and the black hole – bulge (M BH − σ) relation obtained with this assumption departs significantly from the M BH − σ relation in the local universe. In this study, we first present an investigation of the correlation between the CO...

Abstract— In this paper, the generalized analysis and novel application of the multiple periodic (MP) structure are proposed. Both transmission and radiation performances of one dimensional MP structures are studied. The dispersion relations are analyzed from both layered media (distributive) and lumped circuits aspects. Regarding each aspect, both non-dispersive (conventional) and dispersive (...

Recently, Schlickeiser and Miller have calculated anew the acceleration rate of cosmic rays by fast magnetosonic plasma waves in a small-beta plasma, using a linear dispersion relation. They found that the transit-time damping of fast mode waves provides the dominant contribution to the stochastic acceleration rate of cosmic ray particles, both, in pure fast mode wave turbulence as well as in a...

Most theoretical wave models require the power in the wave magnetic field in order to determine the effect of chorus waves on radiation belt electrons. However, researchers typically use the cold plasma dispersion relation to approximate the magnetic wave power when only electric field data are available. In this study, the validity of using the cold plasma dispersion relation in this context i...

Massive black holes detected in the centers of many nearby galaxies are linearly correlated with the luminosity of the host bulge, the black hole mass being about 0.1% of the bulge mass. An even stronger relation exists between the BH mass (Mbh) and the stellar velocity dispersion in the host bulge. We show that massive BHs of AGNs (measured by reverberation mapping) and their bulge luminosity ...
