Hector Workshop



Hector Science Workshop


The AAO would like to invite the astronomy community to a Hector Science Workshop in Sydney on Tuesday 14th Feb 2017. The development of Hector is now well advanced, with the science requirements for this instrument now locked in and construction of the forerunner “Hector-I” instrument now underway. However, significant funding challenges lie ahead in building the full 3-degree-field Hector and hence realizing the science that motivates its construction. This workshop is being organized to bring the community together to be briefed in detail on the status of Hector, including the benefits of Hector-I over SAMI and the full Hector over Hector-I, and for discussion of the scientific and technical trades associated with these stages.


The format of the workshop will be a combination of science/technical talks given by members of the AAO/USyd Hector team, and invited speakers interleaved with discussion sessions.

We strongly encourage all astronomers who envisage using HECTOR for their science to attend this important workshop.

The workshop will also be used as an opportunity to discuss the interaction between Hector and both TAIPAN and WAVES, to ensure an initial input catalogue is in place before the start of the galaxy survey that will be conducted with Hector-I.

What is Hector?

Hector will decipher the diversity of galaxies through understanding their individuality.

The Hector concept is a major new multi-object IFU instrument for the AAT. It builds on the success of the SAMI instrument and will have substantially more capability.

The development of Hector involves a staged approach:

  •   Hector-I: on-sky end 2018; 21 hexabundles over a 2-degree-field; all galaxies imaged to 2 effective radii; 2,000 galaxies/year; this is now funded.
  •   Hector-3dF: on-sky 2022; 50-90 hexabundles over 3-degree-field; all galaxies imaged to 2 effective radii; 45,000-80,000 galaxy survey. Hector-3dF will be the only instrument capable of relating galaxy structure and dynamics to large-scale structure to understand the individuality of galaxies.

The scientific specifications of Hector-3dF are primarily set by the requirements of the Hector Galaxy Survey:

  •    Sample size at least 15 times that of the SAMI Galaxy Survey.
  •    Broad range in stellar mass, morphology and environment; z<~0.15; r-band <~20 magnitudes.
  •    1.3Å spectral resolution (R~3000 in blue and 5000 in red) from 3727 to 7761Å
  •   15-30 arcsec per galaxy (2Re for 90% of galaxies) with spatial sampling of ~2”

If you would like more details on Hector before the meeting then please email jbryant@aao.gov.au

Lunch will be provided

Location: AAO headquarters at North Ryde in meeting room 1 and 2.

The AAO North Ryde offices are ~700m from the North Ryde train station, see https://www.aao.gov.au/files/AAO_Visitor_Traffic_Plan_Final.pdf for visitor parking information. If you enter the complex from Delhi Road, the reception and Meeting Room 1 are located in the building on the right.

The workshop is limited to a maximum of ~50 people.
