Multi-step VLBI observations of weak extragalactic radio sources to align the ICRF and the future GAIA frame
G. Bourda, P. Charlot, R. Porcas +1
The space astrometry mission GAIA will construct a dense optical QSO-based celestial reference frame. For consistency between optical and radio positions, it will be important to a…
VLBI analyses with the GINS software for multi-technique combination at the observation level
G. Bourda, P. Charlot, R. Biancale
A rigorous approach to simultaneously determine a Terrestrial Reference Frame (TRF) and Earth Orientation Parameters (EOP) is now currently applied on a routine basis in a coordina…
GINS: a new tool for VLBI Geodesy and Astrometry
G. Bourda, P. Charlot, R. Biancale
In the framework of the "Groupe de Recherches de Géodésie Spatiale" (GRGS), a rigorous combination of the data from five space geodetic techniques (VLBI, GPS, SLR, LLR and DORIS) i…
A Vlbi Survey of Weak Extragalactic Radio Sources for the Alignment of the Icrf and the Future Gaia Frame
G. Bourda, P. Charlot, R. Porcas +1
The space astrometry mission GAIA will construct a dense optical QSO-based celestial reference frame. For consistency between the optical and radio positions, it will be important…
Massive Infrared-Quiet Dense Cores: Unveiling the Initial Conditions of High-Mass Star Formation
Frédérique Motte, S. Bontemps, N. Schneider +2
As Pr. Th. Henning said at the conference, cold precursors of high-mass stars are now "hot topics". We here propose some observational criteria to identify massive infrared-quiet d…
