Cosmic CARNage I: on the calibration of galaxy formation models
Alexander Knebe, Frazer R. Pearce, Violeta Gonzalez-Perez +31
We present a comparison of nine galaxy formation models, eight semi-analytical and one halo occupation distribution model, run on the same underlying cold dark matter simulation (c…
Using Velocity Dispersion to Estimate Halo Mass: Is the Local Group in Tension with CDM?
Pascal J. Elahi, Chris Power, Claudia del P. Lagos +2
Satellite galaxies are commonly used as tracers to measure the line-of-sight velocity dispersion () of the dark matter halo associated with their central galaxy, and t…
The impact of dark energy on galaxy formation. What does the future of our Universe hold?
Jaime Salcido, Richard G. Bower, Luke A. Barnes +6
We investigate the effect of the accelerated expansion of the Universe due to a cosmological constant, , on the cosmic star formation rate. We utilise hydrodynamical simulations…
Dark Matter Annihilation Feedback in cosmological simulations I: Code convergence and idealised halos
Nikolas Iwanus, Pascal. J. Elahi, Geraint. F. Lewis
We describe and test a novel Dark Matter Annihilation Feedback (DMAF) scheme that has been implemented into the well known cosmological simulation code \textsf{GADGET-2}. In the mo…
2MTF VI. Measuring the velocity power spectrum
Cullan Howlett, Lister Staveley-Smith, Pascal J. Elahi +7
We present measurements of the velocity power spectrum and constraints on the growth rate of structure , at redshift zero, using the peculiar motions of 2,062 galaxies in t…
Cosmic Voids in Evolving Dark Sector Cosmologies: the Low Redshift Universe
Eromanga Adermann, Pascal J. Elahi, Geraint F. Lewis +1
We present a comparison of void properties between the standard model of cosmology, Cold Dark Matter (CDM), and two alternative cosmological models with evolving and interac…
