Sub-milliarcsecond precision spectro-astrometry of Be stars
Context. The origin of the disks around Be stars is still not known. Further progress requires a proper parametrization of their structure, both spatially and spectrally. This is challenging as the disks are very small. Aims. Here we assess whether a novel method is capable of providing these data. Methods. We obtained spectro-astrometry around the Paβ line of two bright Be stars, α Col and ζ T...
متن کاملMillimetre - VLBI Monitoring of AGN with Sub - milliarcsecond Resolution
Global millimetre VLBI allows detailed studies of the most central jet regions of AGN with unprecedent spatial resolution of a few 100–1000 Schwartzschild radii to be made. Study of these regions will help to answer the question how the highly relativistic AGN jets are launched and collimated. Since the early 1990s, bright mm-sources have been observed with global 3 mm VLBI. Here we present new...
متن کاملSub-milliarcsecond Imaging of Quasars and Active Galactic Nuclei
We have used the Very Long Baseline Array at 15 GHz to image the structure of 132 strong compact active galactic nuclei (AGNs) and quasars with a resolution better than 1 mas and a dynamic range typically exceeding 1000 :1. These observations were made as part of a program to investigate the subparsec structure of quasars and AGNs and to study the changes in their structure with time. Many of t...
متن کاملVLBI observations of CygnusA with sub-milliarcsecond resolution
We present new images of the two-sided VLBIstructure of the radio galaxy CygnusA at 1.6GHz, 22GHz and 43GHz. The maps show the jet and counter-jet of CygnusA on scales from ∼ 400 to 0.1 milliarcseconds, corresponding to projected sizes of ∼ 300 pc to 0.07 pc. Our best 22GHz image shows a small (few degree) misalignment of the VLBI-jets with the kpc-jets, longitudinal oscillations of the jet’s r...
متن کاملSub-Microarcsecond Astrometry and New Horizons in Relativistic Gravitational Physics
Attaining the limit of sub-microarcsecond optical resolution will completely revolutionize fundamental astrometry by merging it with relativistic gravitational physics. Beyond the sub-microarcsecond threshold, one will meet in the sky a new population of physical phenomena caused by primordial gravitational waves from the early universe and/or di erent localized astronomical sources, space-time...
