EMU/GAMA: A statistical perspective on active galactic nuclei diagnostics
J. Prathap, A. M. Hopkins, R. Carvajal +19
While it is well known that galaxies are composites of many emission processes, quantifying the various contributions remains challenging. In this work, we use unsupervised machine…
Identification of Anomalous E+A Galaxies in GAMA Using an Isolation Forest
Kieran Broadbelt, Kevin Pimbblet, Daniel J. Farrow
We implement an outlier detection model, an Isolation Foest (iForest), to uncover anomalous objects in the Galaxy and Mass Assembly Fourth Data Release (GAMA DR4). The iForest algo…
FLASH Early Science -- Discovery of an intervening HI 21-cm absorber from an ASKAP survey of the GAMA 23 field
J. R. Allison, E. M. Sadler, S. Bellstedt +18
We present early science results from the First Large Absorption Survey in HI (FLASH), a spectroscopically blind survey for 21-cm absorption lines in cold hydrogen HI gas at cosmol…
Galaxy And Mass Assembly (GAMA): Defining Passive Galaxy Samples and Searching for the UV Upturn
S. Phillipps, S. S. Ali, M. N. Bremer +16
We use data from the GAMA and GALEX surveys to demonstrate that the UV upturn, an unexpected excess of ultraviolet flux from a hot stellar component, seen in the spectra of many ea…
The WiggleZ Dark Energy Survey: Final Data Release and the Metallicity of UV-Luminous Galaxies
Michael J. Drinkwater, Zachary J. Byrne, Chris Blake +24
The WiggleZ Dark Energy Survey measured the redshifts of over 200,000 UV-selected (NUV<22.8 mag) galaxies on the Anglo-Australian Telescope. The survey detected the baryon acoustic…
Galaxy And Mass Assembly: search for a population of high-entropy galaxy groups
Richard J. Pearson, Trevor J. Ponman, Peder Norberg +7
Observations with the Chandra X-ray Observatory are used to examine the hot gas properties within a sample of 10 galaxy groups selected from the Galaxy And Mass Assembly survey's o…
The Taipan Galaxy Survey: Scientific Goals and Observing Strategy
Elisabete da Cunha, Andrew M. Hopkins, Matthew Colless +37
Taipan is a multi-object spectroscopic galaxy survey starting in 2017 that will cover 2pi steradians over the southern sky, and obtain optical spectra for about two million galaxie…
The Large Area Radio Galaxy Evolution Spectroscopic Survey (LARGESS): Survey design, data catalogue and GAMA/WiggleZ spectroscopy
John H. Y. Ching, Elaine M. Sadler, Scott M. Croom +6
We present the Large Area Radio Galaxy Evolution Spectroscopic Survey (LARGESS), a spectroscopic catalogue of radio sources designed to include the full range of radio AGN populati…
An accurate new method of calculating absolute magnitudes and K-corrections applied to the Sloan filter set
Richard Beare, Michael Brown, Kevin Pimbblet
We describe an accurate new method for determining absolute magnitudes, and hence also K-corrections, which is simpler than most previous methods, being based on a quadratic functi…
The Clustering and Halo Masses of Star Forming Galaxies at z<1
Tim Dolley, Michael J. I. Brown, Benjamin J. Weiner +8
We present clustering measurements and halo masses of star forming galaxies at 0.2 < z < 1.0. After excluding AGN, we construct a sample of 22553 24 μm sources selected from 8.42 d…
Separating the conjoined red clump in the Galactic Bulge: Kinematics and Abundances
Roberto De Propris, R. Michael Rich, Andrea Kunder +8
We have used the AAOMEGA spectrograph to obtain R spectra of 714 stars that are members of two red clumps in the Plaut Window Galactic bulge field $(l,b)=0^{\circ},-8^{…
