Present situationtatusCritical Design Review made in January

50% paid (this includes addition for Nasmythoption)

Antenna will arrive at the peakin the first semester of 2016

Optical design of set of mirrors to bring thebeam to the receivers is ready. Mechanicaldesign and robotic system will be madeby Fernando Santoro

Two of the set of desired receiversand the cryostats will be provided byinternational collaborations

average surface RMS value is 5,36µm

IF

LLAMA scientific objectives

• VLBI images of regions a few times the horizon size of super- massive black holes (e.g. Sgr A*, Cen A, etc.).

• Galaxy Formation in the Early Universe

• How relativistic jets are released, accelerated & collimated.

• Extragalactic megamasers of water molecules

• Masers of recombination lines of the hydrogen atom.

• Masers in stellar forming regions & stellar envelopes

• Molecular evolution of interstellar clouds and Astrobiology

• Spiral structure of the Galaxy and other galaxies

• Molecular absorption in front of quasars at very high Zs

• Non-thermal processes in stellar magneto-spheres

• Extra-solar planets and proto-planetary disks

• Polarimetry of radio sources and of the Interstellar Medium

• Solar Physics

with LLAMA we will supervise master and PhD theses in radioastronomy

Consequences

Excellent international collaborations are being established with NOVA,Chalmers Univ., NAOJ, Univ. Chile

Terahertz Laboratory will be installed at Escola Politecnica,University of Sao Paulo, with starting projects in “smart transceivers”, slow-wave devices on MnM substrates i,mager for medical applications, 94 GHz radar for Meteorology) THz Camera/Spectrometer for LLAMA,Among others

Scientific meeting in April 2015 with external advisers and Brazilian/Argentinean community . In preparation for thiswe asked to the community, by means of the Brazilian Astronomical Society, to suggest Key Programs.Positive answers were obtained.

Instrumentation workshop will be organized in collaboration with the other projects

Astrochemistry wokshop will be organized in July 2016 by one of these independent groups

Contact with Brazilian industry will be made for the contruction of mirrors
