SDSS surface photometry of M 31 with absorption corrections
Elmo Tempel, Taavi Tuvikene, Antti Tamm +1
The objective of this work is to obtain an extinction-corrected distribution of optical surface brightness and colour indices of the large nearby galaxy M 31 using homogeneous obse…
A survey of top quark polarization at a polarized linear e^+ e^- collider
S. Groote, J. G. Körner, B. Melić +1
We discuss in detail top quark polarization in above-threshold (t \bar t)-production at a polarized linear e^+ e^- collider. We pay particular attention to the minimization and max…
SDSS DR7 superclusters. The catalogues
L. J. Liivamägi, E. Tempel, E. Saar
We have constructed a set of supercluster catalogues for the galaxies from the SDSS survey main and luminous red galaxy (LRG) flux-limited samples. To delineate superclusters, we c…
Galaxy morphology, luminosity and, environment in the SDSS DR7
E. Tempel, E. Saar, L. J. Liivamägi +4
We study the influence of the environment on the evolution of galaxies by investigating the luminosity function (LF) of galaxies of different morphological types and colours at dif…
Contribution of interband effects caused by long-wavelength transverse optical phonons to electron-phonon coupling in doped polar insulators
Aleksandr Pishtshev
We estimate the contribution of the long-wavelength el-TO-ph interaction and discuss the effect it has on electron pairing in doped polar systems like SrTiO3 and PbTe. The analytic…
Analytic and geometric properties of photoinduced effects in noncentrosymmetric crystals: photovoltaic current and optical rectification
A. Pishtshev, N. Kristoffel
An original dispersion relation between the stationary coherent nonlinear optical responses by current and polarisation is obtained. The dispersion relation provides a new complime…
