Extracting galaxy merger timescales I: Tracking haloes with WhereWolf and spinning orbits with OrbWeaver
Rhys J. J. Poulton, Chris Power, Aaron S. G. Robotham +1
Hierarchical models of structure formation predict that dark matter halo assembly histories are characterised by episodic mergers and interactions with other haloes. An accurate de…
Characterising the Structure of Halo Merger Trees Using a Single Parameter: The Tree Entropy
Danail Obreschkow, Pascal J. Elahi, Claudia del P. Lagos +2
Linking the properties of galaxies to the assembly history of their dark matter haloes is a central aim of galaxy evolution theory. This paper introduces a dimensionless parameter…
From the far-ultraviolet to the far-infrared -- galaxy emission at in the Shark semi-analytic model
Claudia del P. Lagos, Aaron S. G. Robotham, James W. Trayford +8
We combine the Shark semi-analytic model of galaxy formation with the ProSpect software tool for spectral energy distribution (SED) generation to study the multi-wavelength emissio…
From Stellar Halos to Intracluster Light: the physics of the Intra-Halo Stellar Component in cosmological hydrodynamical simulations
Rodrigo Cañas, Claudia del P. Lagos, Pascal J. Elahi +4
We study the Intra-Halo Stellar Component (IHSC) of Milky Way-mass systems up to galaxy clusters in the Horizon-AGN cosmological hydrodynamical simulation. We identify the IHSC usi…
The HI Velocity Function: a test of cosmology or baryon physics?
G. Chauhan, C. D. P. Lagos, D. Obreschkow +3
Accurately predicting the shape of the HI velocity function of galaxies is regarded widely as a fundamental test of any viable dark matter model. Straightforward analyses of cosmol…
Dark Matter Annihilation Feedback in Cosmological Simulations II: The Influence on Gas and Halo Structure
N. Iwanus, P. J. Elahi, F. List +1
We present new cosmological hydrodynamic simulations that incorporate Dark Matter Annihilation Feedback (DMAF), whereby energy released from the annihilation of dark matter particl…
The Three Hundred Project: Ram pressure and gas content of haloes and subhaloes in the phase-space plane
Jake Arthur, Frazer R. Pearce, Meghan E. Gray +12
We use TheThreeHundred project, a suite of 324 resimulated massive galaxy clusters embedded in a broad range of environments, to investigate (i) how the gas content of surrounding…
