Stellar dynamics observations of a double nucleus in M 83
N. Thatte, M. Tecza, R. Genzel
We report on the discovery of a double nucleus in M 83, based on measurements of the line of sight velocity distribution of stars observed at near infrared wavelengths with the VLT…
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…
Optical follow-up of the REFLEX survey: a new perspective in cluster studies
L. T. Barone, E. Molinari, H. Boehringer +8
After the completion of the catalogue built with ESO key program (REFLEX), we are beginning to explore the multiband optical characteristics of a subsample of those clusters select…
The HST snapshot survey of the B2 sample of low luminosity radio-galaxies: a picture gallery
A. Capetti, H. R. de Ruiter, R. Fanti +3
A Hubble Space Telescope snapshot survey of the B2 sample of low luminosity radio galaxies has, at present, produced V and I images of 41 objects. Together with 16 images of B2 sou…
SNR0540-69 -the Crab twin- revisited: Chandra vs. HST
P. A. Caraveo, R. P. Mignani, A. De Luca +2
High resolution images of the Crab-like SNR SNR0540-69 have been recently obtained by the HRC, on board the Chandra X-ray Observatory, and by the FORS1 instrument, attached to ESO/…
HST as a reliable astrometric tool for pulsar astronomy: the cases of the Vela and Geminga pulsars
A. De Luca, R. P. Mignani, P. A. Caraveo
The quest for the distance of the Vela and Geminga pulsars yielded, so far, a set of four WFPC2 images for each object. The availability of couples of images taken at the same peri…
