Science with the AAT

• GALAHAD will unravel the chemo-dynamic structure and evolution of the Milky Way disk, decipher the assembly history of the Galaxy, and provide the benchmark abundance measurements that will underpin all future Galactic surveys. This project will yield key constraints on the evolution of disk galaxies, trace past accretion events in the history of the Galaxy, and undertake a census of Milky Way clusters. GALAHAD builds on the foundation of the existing GALAH survey, but will obtain spectra at higher resolution and higher signal-to-noise.
• The OzARCH Stellar Streams Survey will map the kinematic and chemical properties of the substructure that inhabits the tenuous stellar halo of our Milky Way. These substructures – in the form of streams, shells, and shreds – are the dismembered remains of smaller galaxies accreted onto our Galaxy. As well as providing a unique snapshot of galaxy evolution, reconstructing the dynamical history of this stellar substructure holds the promise of revealing the details of the immense dark matter halo that forms the dominant mass component of the Milky Way. 
• Hector Galaxy Survey. The Hector Galaxy Survey is an integral field survey of 15,000 galaxies at z<0.12 to measure gas and stellar kinematics to understand how large-scale structure and environment drives galaxy angular momentum, accretion of gas, and star formation.
• The Veloce Exoplanet Survey. Humanity’s view of our place in the Universe has changed dramatically over the last 25 years, with thousands of new planets discovered orbiting other stars. The AAT’s Veloce facility was specifically implemented to measure the masses of these planets. When combined with other data, Veloce will be able to distinguish between planets that are icy (like Neptune) from those that are rocky (like Earth). Additionally, Veloce will discover other planets. If there is one thing we have learnt over the last two decades, it is that exoplanetary systems look nothing like our own Solar System.

• The Southern Stellar Stream Spectroscopy Survey. The Southern Stellar Stream Spectroscopic Survey (S⁵) is a spectroscopic survey of stars in the stellar streams of the Southern sky, with the aim of mapping their kinematics and chemistry. The streams represent material tidally striped from dwarf galaxies and globular clusters, and are essential dynamical probes of the dark matter distribution of the Milky Way, as well as providing a detailed snapshot of its accretion history.
• GALAH A spectroscopic survey of 1 million galactic stars to measure elemental abundances and measure stellar kinematics to understand the formation history of our Milky Way galaxy.
• DEVILS The Deep Extragalactic VIsible Legacy Survey (DEVILS) is a spectroscopic campaign at the Anglo-Australian Telescope aimed at bridging the near and distant Universe by producing the highest completeness survey of galaxies and groups at intermediate redshifts (0.3<z<1.0). Our sample will consist of ~58k galaxies to Ymag<21.2, over ~6 sq. deg. to >95% completeness in three well studies deep extragalactic fields (COSMOS, ECDFS and XMM-LSS).
• OzDES A survey to measure the redshifts of tens of thousands of galaxies and obtain spectra of supernovae and other transients. The galaxy redshifts were used to make the most detailed measurement of the Universe's expansion history, leading to a better understanding of the physics behind the acceleration of the Universe.
• SAMI A spatially-resolved spectroscopic survey of ~3000 galaxies, the largest ever to date, to explore the kinematics and internal astrophysical processes of galaxies to understand galaxy formation.
• 2dFLens A spectroscopic survey of 100,000 galaxies to test gravitational physics by comparing the velocities of galaxy lenses with the shape distortions of background galaxies caused by weak gravitational lensing, and to perform photometric redshift calibration of the input imaging surveys.
• The Anglo-Australian Planet Search The Southern Hemisphere's most precise planet search program.
• GAMA A redshift survey of 300,000 galaxies to study structure on scales of 1 kpc to 1 Mpc. This includes galaxy clusters, groups, mergers and coarse measurements of galaxy structure (i.e., bulges and discs). It is on these scales where baryons play a critical role in the galaxy formation and subsequent evolutionary processes and where our understanding of structure in the Universe breaks down.
• RAVE Using the kinematics and abundances of stars to probe the history of our Galaxy
• WiggleZ A redshift survey of 250,000 star-forming galaxies to detect baryonic acoustic oscillations in galaxy clustering, and measure the equation of state of dark energy
• The 2dF Galaxy Redshift Survey Redshifts for more than 220,000 galaxies acquired with the AAT providing a unique map of the Universe, confirming the existence of dark energy and exploring galaxy formation and evolution.
• The 2dF Quasar Redshift survey Redshifts for 35,000 quasars acquired with the AAT.
• The UKST H-alpha Survey Observing the entire Galactic Plane in a hydrogen emission line.
• The 6dF Galaxy Survey Redshifts for more than 120,000 infrared-selected galaxies in the local Universe acquired with the UKST for measuring the bulk flow of galaxies to understand cosmology.
