The SAMI Galaxy Survey: Observing the environmental quenching of star formation in GAMA groups
A. L. Schaefer, S. M. Croom, N. Scott +25
We explore the radial distribution of star formation in galaxies in the SAMI Galaxy Survey as a function of their local group environment. Using a sample of galaxies in groups (wit…
The SAMI Galaxy Survey: Stellar and gas misalignments and the origin of gas in nearby galaxies
J. J. Bryant, S. M. Croom, J. van de Sande +16
Misalignment of gas and stellar rotation in galaxies can give clues to the origin and processing of accreted gas. Integral field spectroscopic observations of 1213 galaxies from th…
A numerical twist on the observational spin parameter,
K. E. Harborne, C. Power, A. S. G. Robotham +2
A primary goal of integral field spectroscopic (IFS) surveys is to provide a statistical census of galaxies classified by their internal kinematics. As a result, the observational…
Galaxy And Mass Assembly (GAMA): The sSFR-M* relation part I - -M* as a function of sample, SFR indicator and environment
L. J. M. Davies, C. del P. Lagos, A. Katsianis +11
Recently a number of studies have proposed that the dispersion along the star formation rate - stellar mass relation (-M) is indicative of variations in st…
Major mergers between dark matter haloes -- II. Profile and concentration changes
Nicole E. Drakos, James E. Taylor, Anael Berrouet +2
Several lines of evidence suggest that as dark matter haloes grow their scale radius increases, and that the density in their central region drops. Major mergers seem an obvious me…
Major mergers between dark matter haloes -- I. Predictions for size, shape, and spin
Nicole E. Drakos, James E. Taylor, Anael Berrouet +2
The structural properties of individual dark matter haloes, including shape, spin, concentration, and substructure, are linked to the halo's growth history, but the exact connectio…
WALLABY Early Science - I. The NGC 7162 Galaxy Group
Tristan N. Reynolds, Tobias Westmeier, Lister Staveley-Smith +21
We present Widefield ASKAP L-band Legacy All-sky Blind Survey (WALLABY) early science results from the Australian Square Kilometre Array Pathfinder (ASKAP) observations of the NGC…
The XXL Survey: XXVII. The 3XLSS point source catalogue
L. Chiappetti, S. Fotopoulou, C. Lidman +35
We present the version of the point source catalogue of the XXL Survey that was used, in part, in the first series of XXL papers. In this paper we release, in our database in Milan…
Observing Merger Trees in a New Light
Rhys J. J. Poulton, Aaron S. G. Robotham, Chris Power +1
Merger trees harvested from cosmological -body simulations encode the assembly histories of dark matter halos over cosmic time, and are a fundamental component of semi-analytica…
GAMA/G10-COSMOS/3D-HST: Evolution of the galaxy stellar mass function over 12.5Gyrs
Angus H. Wright, Simon P. Driver, Aaron S. G. Robotham
Using a combined and consistently analysed GAMA, G10-COSMOS, and 3D-HST dataset we explore the evolution of the galaxy stellar-mass function over lookback times $t_{\rm L} \in \lef…
Shark: introducing an open source, free and flexible semi-analytic model of galaxy formation
Claudia del P. Lagos, Rodrigo J. Tobar, Aaron S. G. Robotham +4
We present a new, open source, free semi-analytic model (SAM) of galaxy formation, Shark, designed to be highly flexible and modular, allowing easy exploration of different physica…
Deep Extragalactic VIsible Legacy Survey (DEVILS): Motivation, Design and Target Catalogue
L. J. M. Davies, A. S. G. Robotham, S. P. Driver +26
The Deep Extragalactic VIsible Legacy Survey (DEVILS) is a large spectroscopic campaign at the Anglo-Australian Telescope (AAT) aimed at bridging the near and distant Universe by p…
The XXL Survey: XXX. Characterisation of the XLSSsC N01 supercluster and analysis of the galaxy stellar populations
V. Guglielmo, B. M. Poggianti, B. Vulcani +34
Superclusters form from the largest enhancements in the primordial density perturbation field and extend for tens of Mpc, tracing the large-scale structure of the Universe. We char…
Galaxy And Mass Assembly (GAMA): Gas Fuelling of Spiral Galaxies in the Local Universe II. -- Direct Measurement of the Dependencies on Redshift and Host Halo Mass of Stellar Mass Growth in Central Disk Galaxies

We present a new scheme, , for refining the photometric redshift measurements of faint galaxies by probabilistically tagging them to observed galaxy groups constructed…
Jeans that fit: weighing the mass of the Milky Way analogues in the universe
Prajwal R. Kafle, Sanjib Sharma, Aaron S. G. Robotham +2
The spherical Jeans equation is a widely used tool for dynamical study of gravitating systems in astronomy. Here we test its efficacy in robustly weighing the mass of Milky Way ana…
The Need for Speed: Escape velocity and dynamical mass measurements of the Andromeda galaxy
Prajwal R. Kafle, Sanjib Sharma, Geraint F. Lewis +2
