This edition of the Australian Astronomical Observatory Observer contains articles on the detection of the baryonic acoustic oscillation signal over a wide range of redshifts by the WiggleZ dark energy survey; results and future plans for…

The newsletter of the Australian Astronomical Observatory. In this issue: SPIE Extravaganza; The AAO's Gemini High-resolution Optical SpecTrograph (GHOST) concept; First Cosmological Constraints from the 6dFGS Peculiar Velocity Field;…

The Feburary 2010 edition of the AAO newsletter contains articles on Helium-rich subluminous B stars, the discovery of large-scale gravitationall infall in a massive proto-stellar cluster, HERMES: the new multi-object high-resolution…

This edition of the Australian Astronomical Observatory Observer contains articles on the commissioning of the new SAMI instrument giving the first hexabundle galaxy spectra; galaxy parameter variations across and through the 6dFGS…

The August 2010 edition of the AAO newsletter has been newly updated and renamed the AAO Observer as we become the Australian Astronomical Observatory. This edition contains articles on the Galaxy And Mass Assembly survey, a bipolar Type I…

The February 2009 edition of the AAO newsletter contains articles on the preliminary results from the WiggleZ dark energy survey, the analysis of near-IR observations of the galaxy IRAS18293-3413, the early results from the SPIRAL IFU…

The August 2009 edition of the AAO newsletter contains articles on observations of the lunar impact of the Kaguya satellite, mapping the ISM towards Omega Centauri, early results from the Anglo-Australian Rocky Planet search, details of a…

AAOmega is the new spectrograph for the 2dF fibre-positioning system on the Anglo-Australian Telescope. It is a bench-mounted, double-beamed design, using volume phase holographic (VPH) gratings and articulating cameras. It is fed by 392…

We present a description of the Australian Dark Energy Survey (OzDES) and summarise the results from its six years of operations. Using the 2dF fibre positioner and AAOmega spectrograph on the 3.9-metre Anglo-Australian Telescope, OzDES has…

Cosmological distances inferred from supernova Ia observations constitute the most direct and solid evidence for the recently detected accelerated expansion of the universe. In this contribution, we show some inconsistencies between two of…

Study of radio supernovae over the past 25 years includes two dozen detected objects and more than 100 upper limits. From this work it is possible to identify classes of radio properties, demonstrate conformance to and deviations from…

We present the first public database of high-energy observations of all known Galactic supernova remnants (SNRs). In section 1 we introduce the rationale for this work motivated primarily by studying particle acceleration in SNRs, and which…

This paper presents the first major data release and survey description for the ANU WiFeS SuperNovA Program (AWSNAP). AWSNAP is an ongoing supernova spectroscopy campaign utilising the Wide Field Spectrograph (WiFeS) on the Australian…

Type Ia supernovae (SN Ia) have provided the first evidence for an accelerating universe and for the existence of an unknown ``dark energy'' driving this expansion. The 5-year Supernova Legacy Survey (SNLS) will deliver \~700 type Ia…

We are building a next-generation laser adaptive optics system, Robo-AO-2, for the UH 2.2-m telescope that will deliver robotic, diffraction-limited observations at visible and near-infrared wavelengths in unprecedented numbers. The…

This is a pedagogical review of the recent observational data obtained from type Ia supernova surveys that support the accelerating expansion of the universe. The methods for the analysis of the data are reviewed and some of the theoretical…

We use the wide-field capabilities of the 2dF fibre positioner and the AAOmega spectrograph on the Anglo-Australian Telescope (AAT) to obtain redshifts of galaxies that hosted supernovae during the first three years of the Supernova Legacy…

Type Ia supernovae (SNe Ia) currently provide the most direct evidence for an accelerating Universe and for the existence of an unknown "dark energy" driving this expansion. The 5-year Supernova Legacy Survey (SNLS;…

With its excellent sensitivity, large field of view, broad energy coverage, and good per-photon angular resolution, the Large Area Telescope aboard the Fermi Gamma-ray Space Telescope satellite provides us with an unprecedented view of the…

We report on the 2dF Galaxy and QSO Redshift Surveys now in progress with the Two Degree Field facility at the Anglo-Australian Observatory. We describe the 2dF instrumentation, outline the scientific aims of the surveys and their current…
