Abstract The objective of this project is prepare targets to be study with LLAMA (Long Latin American Millimeter Array), that initially it will consist of one antenna installed in the Argentina size of Atacama desert, around 150 Km of ALMA (Atacama Large Millimeter Array). The radiotelescope of LLAMA project will operates at initial phase in frequencies of 43, 100 and 660 GHz, the first one is coincident with the band present at Itapetinga Radio Observatory. LLAMA will have two different observations modes: "single dish" and VLBI. In the single dish mode, it will be used to study Active Galactic Nuclei (AGNs) in all the frequencies band, increasing the work realized in the Itapetinga Observatory since years 70s, at frequencies of 22 and 43 GHz. LLAMA operation as VLBI will enable the AGNs studies in millisecond arc second scale that corresponds around 100 parsecs, allowing a north-south resolution that cannot be reached using only North Hemisphere telescopes. In this work, we will continue the monitoring programs started in the last 10 years; most of them were an important part of my graduate studies. The sources that we will study are SgrA*, Eta Carinae, Centaurus A and luminous quasars, as 3C273, 3C279, OJ287 and 1510-089. Beyond the monitoring program, we will analyze our results comparing with it was obtained in interferometric images. In some cases, as Eta Carina, we already realize observations with ALMA and the published results will be discussed together with next minimum of the 7mm light curve, predict to happen in 2014 July. In SgrA*, we will analyze our new observations and compare with the results of the report program NRAO-VLA Service Observing, with the main objective to understanding the flux excess detected in the single dish light curve, as we reported in a paper published in 2013. At last, this project is inside the LLAMA project, and we also have as objective the development and improvement of observing technique using multiples antennas, to be applied for either our data analyses and the first years of LLAMA. For that, we will keep a collaboration with IRAM (institute de Radioastronomie Millimétrique) staff, that administrates the Plareau de Bure Observatory, localized in France, and Pico de Valeta Observatory, localized in Spain. | |
