5 Nov 2014 - Breaking News: Veloce Rosso has been funded by a LIEF 2015 grant awarded to a consortium led by UNSW and including ANU, USQ, AAO, Sydney and Macquarie. Thanks to additional contributions by UNSW and USQ we are now fully funded at $1.65m!

The Veloce project aims to equip the Anglo-Australian Telescope with a compact ultra-stabilised spectrograph, able to obtain Doppler velocities for Sun-like and M-dwarf stars at sub-m/s precision. It will provide essentially all the functionality delivered by the current UCLES spectrograph, with a larger collecting area from the sky, large simultaneous wavelength coverage, higher resolution and better throughput.

Veloce Rosso's key features are

  1. IFU Fibre-feed as demonstrated by the CYCLOPS Facilities

  2. Compact asymmetric, white-pupil design, including pressure and temperature stabilisation.

  3. Wavelength coverage from ~ 600-950nm at R~80,000

  4. Simultaneous calibration utilising ThXe, UNe and (when available) laser-comb or photonic ring-resonator technologies.

Upgrades for Veloce Rosso planned for the future are

  1. A "faint object" fibre feed and science-quality slit-viewing camera.

  2. Implement Veloce Verde  - an additional camera delivering data from Hbeta to Halpha at R~80,000.

  3. Implement Veloce Azzurro  - an final camera delivering data from 350-450nm at R~40,000.

  4. Implement a spectro-polarimetry module at the AAT's Cassegrain focus.

  5. Acquire a laser comb.

  6. Implement fibre feeds to Auxiliary Telescopes external to the AAT.
