Seminários de Astronomia: LLAMA Project – Jacques R.D.Lepine (IAG/USP)
1 de novembro de 2017:12:30 - 16:00
The Large Latin American Millimeter Array (LLAMA) is a joint project between Brazil and Argentina for the installation of a 12m-diameter antenna in the Argentine Andes at 4800m to study the Universe in millimeter and sub-millimeter waves. On the brazilian side, the project is funded by FAPESP and led by a research group from IAG-USP; of the argentine side is led by IAR (Argentine Institute of Radio Astronomy).
The project is underway and the installation should be completed by 2018. The antenna will be installed about 20km from San Antonio de los Cobres, province of Salta, and 180km from the great ALMA interferometer. It will work most of the time in single dish mode, but it will perform VLBI (Very Long Base Interferometry) experiments with other telescopes such as ALMA, ASTE, APEX and others more distant, being able to increase by a factor 10 the angular resolution of the ALMA telescope. The first receivers to be installed will be band 5 and band 9 (ALMA band definitions) developed in collaboration with NOVA (Groningen) and GARD (Gothenburg) research groups.
The radio telescope aims to serve a broad community, with diverse scientific objectives, such as solar physics, studies of black holes and their addition disks, extragalactic megamasers, mapping of molecular clouds and their chemical evolution, Structure of the Galaxy, Astrometry and Cosmology.
