Flat-top plasma operational space of the STEP power plant
E. Tholerus, F. J. Casson, S. P. Marsden +16
STEP is a spherical tokamak prototype power plant that is being designed to demonstrate net electric power. The design phase involves the exploitation of plasma models to optimise…
The Environments of Luminous Radio - WISE Selected Infrared Galaxies
J. I. Penney, A. W. Blain, D. Wylezalek +17
We have observed the environments of a population of 33 heavily dust obscured, ultra-luminous, high-redshift galaxies, selected using WISE and NVSS at 1.3 with the Infra-Red Ar…
Galaxy evolution in protoclusters
Stuart I. Muldrew, Nina A. Hatch, Elizabeth A. Cooke
We investigate galaxy evolution in protoclusters using a semi-analytic model applied to the Millennium Simulation, scaled to a Planck cosmology. We show that the model reproduces t…
Enhancement of AGN in a protocluster at z=1.6
Charutha Krishnan, Nina A. Hatch, Omar Almaini +7
We investigate the prevalence of AGN in the high-redshift protocluster - at . Using imaging from the Chandra X-ray Telescope, we find a large overden…
The structure and evolution of a forming galaxy cluster at z = 1.62
N. A. Hatch, S. I. Muldrew, E. A. Cooke +4
We present a comprehensive picture of the Cl0218.3-0510 protocluster at across 10 co-moving Mpc. Using filters that tightly bracket the Balmer and 4000 Angstrom breaks of…
Black Hole Winds II: Hyper-Eddington Winds and Feedback
Andrew King, Stuart I. Muldrew
We show that black holes supplied with mass at hyper--Eddington rates drive outflows with mildly sub--relativistic velocities. These are for Eddington accretion f…
What are Protoclusters? -- Defining High Redshift Galaxy Clusters and Protoclusters
Stuart I. Muldrew, Nina A. Hatch, Elizabeth A. Cooke
We explore the structures of protoclusters and their relationship with high redshift clusters using the Millennium Simulation combined with a semi-analytic model. We find that prot…
Major Mergers Going Notts: Challenges for Modern Halo Finders
Peter Behroozi, Alexander Knebe, Frazer R. Pearce +7
Merging haloes with similar masses (i.e., major mergers) pose significant challenges for halo finders. We compare five halo finding algorithms' (AHF, HBT, Rockstar, SubFind, and VE…
Solving the puzzle of subhalo spins
Yang Wang, Weipeng Lin, Frazer R. Pearce +3
Investigating the spin parameter distribution of subhaloes in two high resolution isolated halo simulations, re- cent work by Onions et al. suggested that typical subhalo spins are…
Galaxy Cluster Mass Reconstruction Project: I. Methods and first results on galaxy-based techniques
L. Old, R. A. Skibba, F. R. Pearce +18
This paper is the first in a series in which we perform an extensive comparison of various galaxy-based cluster mass estimation techniques that utilise the positions, velocities an…
Subhaloes gone Notts: Subhaloes as tracers of the dark matter halo shape
Kai Hoffmann, Susana Planelles, Enrique Gaztanaga +14
We study the shapes of subhalo distributions from four dark-matter-only simulations of Milky Way type haloes. Comparing the shapes derived from the subhalo distributions at high re…
Subhaloes gone Notts: the clustering properties of subhaloes
Arnau Pujol, Enrique Gaztanaga, Carlo Giocoli +13
We present a study of the substructure finder dependence of subhalo clustering in the Aquarius Simulation. We run 11 different subhalo finders on the haloes of the Aquarius Simulat…
Modelling the Growth of Supermassive Black Holes in Cosmological Simulations
Stuart I. Muldrew, Frazer R. Pearce, Chris Power
There is strong evidence that supermassive black holes reside in all galaxies that contain a stellar spheroid and their mass is tightly correlated with properties such as stellar b…
Measures of Galaxy Environment - III. Difficulties in identifying proto-clusters at z ~ 2
Genevieve M. Shattow, Darren J. Croton, Ramin A. Skibba +3
Galaxy environment is frequently discussed, but inconsistently defined. It is especially difficult to measure at high redshift where only photometric redshifts are available. With…
Streams Going Notts: The tidal debris finder comparison project
Pascal J. Elahi, Jiaxin Han, Hanni Lux +6
While various codes exist to systematically and robustly find haloes and subhaloes in cosmological simulations (Knebe et al., 2011, Onions et al., 2012), this is the first work to…
Structure Finding in Cosmological Simulations: The State of Affairs
Alexander Knebe, Frazer R. Pearce, Hanni Lux +32
The ever increasing size and complexity of data coming from simulations of cosmic structure formation demands equally sophisticated tools for their analysis. During the past decade…
Subhaloes gone Notts: Spin across subhaloes and finders
Julian Onions, Yago Ascasibar, Peter Behroozi +15
We present a study of a comparison of spin distributions of subhaloes found associated with a host halo. The subhaloes are found within two cosmological simulation families of Milk…
Measures of galaxy environment -- II. Rank-ordered mark correlations
Ramin A. Skibba, Ravi K. Sheth, Darren J. Croton +4
