Sussing Merger Trees: A proposed Merger Tree data format
Peter A. Thomas, Julian Onions, Dylan Tweed +13
We propose a common terminology for use in describing both temporal merger trees and spatial structure trees for dark-matter halos. We specify a unified data format in HDF5 and pro…
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…
Kinematics and simulations of the stellar stream in the halo of the Umbrella Galaxy
Caroline Foster, Hanni Lux, Aaron J. Romanowsky +9
We study the dynamics of faint stellar substructures around the Umbrella Galaxy, NGC 4651, which hosts a dramatic system of streams and shells formed through the tidal disruption o…
Kinematic transitions and streams in galaxy halos
A. J. Romanowsky, J. A. Arnold, J. P. Brodie +7
The chemo-dynamics of galaxy halos beyond the Local Group may now be mapped out through the use of globular clusters and planetary nebulae as bright tracer objects, along with deep…
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…
Constraining the Milky Way Halo Shape Using Thin Streams
H. Lux, J. I. Read, G. Lake +1
Tidal streams are a powerful probe of the Milky Way (MW) potential shape. In this paper, we introduce a simple test particle method to fit stream data, using a Markov Chain Monte C…
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…
Galaxies going MAD: The Galaxy-Finder Comparison Project
Alexander Knebe, Noam I. Libeskind, Frazer Pearce +8
With the ever increasing size and complexity of fully self-consistent simulations of galaxy formation within the framework of the cosmic web, the demands upon object finders for th…
NGC 5466: a unique probe of the Galactic halo shape
H. Lux, J. I. Read, G. Lake +1
Stellar streams provide unique probes of galactic potentials, with the longer streams normally providing the cleaner measurements. In this paper, we show an example of a short tida…
SubHaloes going Notts: The SubHalo-Finder Comparison Project
Julian Onions, Alexander Knebe, Frazer R. Pearce +14
We present a detailed comparison of the substructure properties of a single Milky Way sized dark matter halo from the Aquarius suite at five different resolutions, as identified by…
Determining orbits for the Milky Way's dwarfs
H. Lux, J. I. Read, G. Lake
We calculate orbits for the Milky Way dwarf galaxies with proper motions, and compare these to subhalo orbits in a high resolution cosmological simulation. We use the simulation da…
Determining orbits for the Milky Way's dwarfs
H. Lux, J. I. Read, G. Lake
We calculate orbits for the Milky Way dwarf galaxies with proper motions, and compare these to subhalo orbits in a high resolution cosmological simulation. We use this same simulat…
