The large-scale structure of the halo of the Andromeda galaxy II. Hierarchical structure in the Pan-Andromeda Archaeological Survey
Alan W. McConnachie, Rodrigo Ibata, Nicolas Martin +29
The Pan-Andromeda Archaeological Survey is a survey of square degrees centered on the Andromeda (M31) and Triangulum (M33) galaxies that has provided the most extensive pano…
The SCUBA-2 Web Survey: I. Observations of CO(3-2) in hyper-luminous QSO fields
Ryley Hill, Scott C. Chapman, Douglas Scott +8
A primary goal of the SCUBA-2 Web survey is to perform tomography of the early inter-galactic medium by studying systems containing some of the brightest quasi-stellar objects (QSO…
The Complete Local Volume Groups Sample - II. A study of the Central Radio Galaxies in the HighRichness Sub-sample
Konstantinos Kolokythas, Ewan O'Sullivan, Somak Raychaudhury +3
We present a study of the radio properties of the dominant early-type galaxies in 26 galaxy groups, the high-richness sub-sample of the Complete Local-volume Groups Sample (CLoGS).…
Dynamic Localised Turbulent Diffusion and its Impact on the Galactic Ecosystem
Douglas Rennehan, Arif Babul, Philip F. Hopkins +2
Modelling the turbulent diffusion of thermal energy, momentum, and metals is required in all galaxy evolution simulations due to the ubiquity of turbulence in galactic environments…
Cold gas in a complete sample of group-dominant early-type galaxies
E. O'Sullivan, F. Combes, P. Salomé +7
We present IRAM 30m and APEX telescope observations of CO(1-0) and CO(2-1) lines in 36 group-dominant early-type galaxies, completing our molecular gas survey of dominant galaxies…
Introducing RomulusC: A Cosmological Simulation of a Galaxy Cluster with Unprecedented Resolution
Michael Tremmel, Thomas R. Quinn, Angelo Ricarte +6
We present the first results from RomulusC, the highest resolution cosmological hydrodynamic simulation of a galaxy cluster run to date. RomulusC, a zoom-in simulation of a halo wi…
A massive core for a cluster of galaxies at a redshift of 4.3
T. B. Miller, S. C. Chapman, M. Aravena +35
Massive galaxy clusters are now found as early as 3 billion years after the Big Bang, containing stars that formed at even earlier epochs. The high-redshift progenitors of these ga…
A limit on the warm dark matter particle mass from the redshifted 21 cm absorption line
Mohammadtaher Safarzadeh, Evan Scannapieco, Arif Babul
The recent EDGES collaboration detection of an absorption signal at a central frequency of MHz points to the presence of a significant Lyman- background by a redsh…
Diversity in the stellar velocity dispersion profiles of a large sample of Brightest Cluster Galaxies
S. I. Loubser, H. Hoekstra, A. Babul +1
We analyse spatially-resolved deep optical spectroscopy of Brightest Cluster Galaxies (BCGs) located in 32 massive clusters with redshifts of 0.05 0.30, to investigat…
Cool-Core Clusters : Role of BCG, Star Formation & AGN-Driven Turbulence
Deovrat Prasad, Prateek Sharma, Arif Babul
Recent analysis shows that it is important to explicitly include the gravitational potential of the central brightest central galaxy (BCG) to infer the acceleration due to gravity…
Feedback from Reorienting AGN Jets
S. Cielo, A. Babul, V. Antonuccio-Delogu +2
[abridged] Aims: We test the effects of re-orienting jets from an active galactic nucleus (AGN) on the intracluster medium in a galaxy cluster environment with short central coolin…
