Collaboration and contribution to the discipline or research base
International collaborations in the Institute of Cosmology and Gravitation have been supported by a number of awards including a Royal Society Research Network with South Africa (NRF) (Nichol), a Royal Society International Joint Project grant with Kyoto University (Koyama) and the Daiwa Anglo-Japanese Foundation, Daiwa Adrian Prize 2010 (Wands).
Staff at the Institute play leading roles in major international collaborations in astronomy, including:
- Sloan Digital Sky Survey (SDSS): Nichol was spokesperson for the collaboration (2009-2011) and Masters is outreach coordinator for SDSS-IV
- Baryon Acoustic Oscillation Survey (BOSS), part of SDSS-III: Maraston is chair of the Galaxy Evolution working group; Tojeiro is co-chair of the Large-Scale Structure working group; Maraston, Nichol, Percival, Thomas and Tojeiro are SDSS-III BOSS “architects” in recognition of their substantial contribution to the whole collaboration, allowing them privileged authorship rights
- eBOSS (extended BOSS), part of SDSS-IV: Percival is survey scientist
- MaNGA, part of SDSS-IV: Nichol is member of the steering committee; Thomas is the Science Team chair; Masters is the co-chair of the Kinematics working group, and Masters and Thomas are both members of management committee
- Galaxy Zoo: Masters is project scientist
- Dark Energy Survey (DES): Nichol is on DES management council, the DES-UK board, and is the co-chair of the Supernovae working group; Percival is the coordinator of Large-Scale Structure working group; Thomas is the coordinator of Galaxy Evolution working group; Bacon leads the mass mapping sub-group for Weak Lensing working group; Nichol, Percival and Thomas are DES “builders”
- LOFAR (Low Frequency Radio Array): Nichol was a member of the LOFAR:UK management committee from 2006 to 2010; Bacon is leading the Surveys Cosmology working group and is a Long Baseline group core team member; Masters was Spokesperson for LOFAR-UK (2009-13) and is on the management committee
- ESA Euclid Satellite: Nichol is on the Euclid Consortium Board and is a member of the Euclid Science Team; Percival is Cosmology and Galaxy Clustering coordinator; Bacon is Gravitational Flexion work package coordinator; Maraston is work package coordinator for the Photometric Redshift working group; Koyama is a non-standard cosmological simulation coordinator for Simulation working group; Zhao is a member of the Forecast and Simulation working groups; Koyama and Maartens are members of the Theory working group.
- ESO VIPER survey: Percival is on the VIPERS steering committee; Tojeiro is a “builder” in VIPERS.
- Square Kilometre Array (SKA): Maartens is SKA research professor at University of Western Cape, South Africa, and chair of the SKA Cosmology working group; Bacon is also a member of the Cosmology working group
Institute of Cosmology and Gravitation researchers are involved in numerous other surveys including GAMA (Galactic Mass Assembly) and SERVS (Spitzer Extragalactic Representative Volume Survey), DESI (Dark Energy Spectroscopic Instrument), DESspec and WEAVE.
The Institute regularly hosts collaboration meetings and workshops in Portsmouth, including the UK Cosmology and Cosmic Superstrings meeting (September 2011), MaNGA meeting (2013), Dark Energy Survey Spring Collaboration meeting (June 2011), Open Puzzles in Galaxy Formation and Evolution (September 2010), VIPERS collaboration meeting (June 2010), Galaxy Zoo 2 Science meeting (October 2009), Unity of the Universe conference (June 2009), Modified Gravity on Cosmological Scales (June 2008). Portsmouth is part of UK Cosmo and Koyama is on the national organising committee. Maartens, Nichol and Percival were on the science committee that organised the first Euclid/SKA science conference (Oxford, 2013). In June 2014 we will host the National Astronomy Meeting in Portsmouth.
