Lamb Shift in Light Hydrogen-Like Atoms
Vladimir G. Ivanov, Savely G. Karshenboim
Calculation of higher-order two-loop corrections is now a limiting factor in development of the bound state QED theory of the Lamb shift in the hydrogen atom and in precision deter…
Numerical Data-Processing Simulations of Microarcsecond Classical and Relativistic Effects in Space Astrometry
Sergei M. Kopeikin, N. V. Shuygina, M. V. Vasilyev +2
The accuracy of astrometric observations conducted via a space-borne optical interferometer orbiting the Earth is expected to approach a few microarcseconds. Data processing of suc…
A New Association of Post-T Tauri Stars Near The Sun
Carlos A. O. Torres, Licio da Silva, Germano R. Quast +2
Observing ROSAT sources in 20 x 25 deg centered at the high latitude active star ER Eri, we found evidences for a new young nearby association (~30Myr at~60pc), the Horologium Asso…
RATAN-600 - VLA - BTA-6m ("BIG TRIO") Project: multicolour studying of distant radio galaxies
Yu. N. Parijskij, W. M. Goss, A. I. Kopylov +4
Powerful radio galaxies belong to the population of massive stellar systems that can be picked at high redshifts. With measured redshift, morphology and age determination these obj…
