A \multi-argus" Facility at Cfht
نویسنده
چکیده
We propose to implement a \multi-argus" facility at CFHT. The main scientiic driver of this project is the study of the evolution of the Tully-Fisher relation at intermediate redshift, thanks to the use of the optical rotation curves of spiral galaxies. The multiplex gain makes this project quite attractive, even on a 4m-size telescope such as CFHT. From the instrumental side, the idea is to modify the multi-ber positionner FIFI (a copy of the MEFOS instrument in use on the ESO 3.6m telescope) and to include small bundles of bers, then x it at the Cassegrain focus and link the bers to the entrance of the MOS. We present the way it would work in the CFHT environment with minor changes and demonstrate the scientiic feasability and the interest of such connguration for several astrophysical programmes.

Discovery of Low-Luminosity Carbon Stars in the Fornax Dwarf Spheroidal Galaxy with MOS at CFHT
We report circumstances and observational techniques used with the CFHT Multi-Object Spectrograph that led us to the discovery of low-luminosity carbon stars in the Fornax dwarf spheroidal galaxy. We review the carbon star surveys carried out with this system and present our main results. A more detailed study based on our CFHT and ESO observations will be published in the proceedings of the IA...
متن کاملCombining data envelopment analysis and multi-objective model for the efficient facility location–allocation decision
This paper proposes an innovative procedure of finding efficient facility location–allocation (FLA) schemes, integrating data envelopment analysis (DEA) and a multi-objective programming (MOP) model methodology. FLA decisions provide a basic foundation for designing efficient supply chain network in many practical applications. The procedure proposed in this paper would be applied to the FLA pr...

متن کاملARGUS: a coordination system to provide first responders with live aerial imagery of the scene of a disaster (demonstration)
We present ARGUS, a coordination system for unmanned aerial vehicles (UAVs) deployed to support situational awareness for disaster management settings. ARGUS is based on the max-sum algorithm, a well known decentralised coordination algorithm for multi-agent systems. In this demonstration, we present an interactive simulation environment, where a user acting as a first responder submits imagery...
