Call for membership of the Hector Galaxy Survey

Hector-I is a new multi-object integral-field spectrograph (IFS) instrument that will be commissioned on the AAT in 2019.
The Hector Galaxy Survey will be the largest IFS galaxy survey, observing 15,000 galaxies over ~5 years on the AAT.
Australia has had significant success with the SAMI IFS instrument. From SAMI we have determined the need for both higher spectral resolution (for de-blending emission line components and measuring higher-order stellar kinematic features - all crucial to the science case) and coverage of galaxies out to 2 effective radii. Hector will deliver both.

The survey is open to all researchers working in Australia, and we are encouraging membership.

If resolved spectroscopy of nearby galaxies overlaps your science, then I would like to strongly encourage you (and your students) to join the Hector Galaxy Survey team. Now is the time to join, as the detailed science cases are being formed ahead of the first observing proposal, and targets selection is underway in order to be ready for observing next year.

In addition, there are some leadership roles to be filled for those people for whom Hector will be a major part of their research and that can commit a defined amount of time to those roles. Effort towards the survey can lead to co-authorship on key survey papers. Please contact me (jbryant at sydney.edu.au<mailto:jbryant at sydney.edu.au>) if you would like to discuss those roles.

I encourage you to take a look at the Hector web site https://protect-au.mimecast.com/s/ZHijCZYM2VFXvDRvCz2ukN?domain=aao.gov.au and sign up to the Hector team by emailing both me and the Science team leaders for your science interests:
• Stellar populations & kinematics: Jesse van de Sande & Nic Scott  (jesse.vandesande at sydney.edu.au<mailto:jesse.vandesande at sydney.edu.au>, nicholas.scott at sydney.edu.au<mailto:nicholas.scott at sydney.edu.au>)
• Gas kinematics: Julia Bryant (jbryant at sydney.edu.au<mailto:jbryant at sydney.edu.au>)
• Emission line processes: Brent Groves (brent.groves at anu.edu.au<mailto:brent.groves at anu.edu.au>)
• Radio/HI connections: Luca Cortese & Barbara Catinella (luca.cortese at uwa.edu.au<mailto:luca.cortese at uwa.edu.au>, barbara.catinella at uwa.edu.au<mailto:barbara.catinella at uwa.edu.au>)
• Clusters: Matt Owers (matt.owers at mq.edu.au<mailto:matt.owers at mq.edu.au>)

Key statistics of Hector-1:
- hexabundles of between 61 and 217 fibres covering 15-30” across each galaxy.
- 21 galaxies per pointing across a 2-degree field.
- z<0.1 galaxy sample selected in stellar mass and redshift bins.
- Spectral resolution of 0.13nm over 372.7-776.1nm range (R>5000 in the red).

If you are already a team member (as listed on the Hector website) then there is no need to sign up again.

Please do contact me if you have any questions.
