Unified dark energy and dark matter from a scalar field different from quintessence
Changjun Gao, Martin Kunz, Andrew R Liddle +1
We explore unification of dark matter and dark energy in a theory containing a scalar field of non-Lagrangian type, obtained by direct insertion of a kinetic term into the energy-m…
Constraining the dark fluid
Martin Kunz, Andrew R Liddle, David Parkinson +1
Cosmological observations are normally fit under the assumption that the dark sector can be decomposed into dark matter and dark energy components. However, as long as the probes r…
An Evolutionary Paradigm for Dusty Active Galaxies at Low Redshift
D. Farrah, B. Connolly, N. Connolly +7
We apply methods from Bayesian inferencing and graph theory to a dataset of 102 mid-infrared spectra, and archival data from the optical to the millimeter, to construct an evolutio…
Optimizing baryon acoustic oscillation surveys II: curvature, redshifts, and external datasets
David Parkinson, Martin Kunz, Andrew R. Liddle +3
We extend our study of the optimization of large baryon acoustic oscillation (BAO) surveys to return the best constraints on the dark energy, building on Paper I of this series (Pa…
Viable inflationary models ending with a first-order phase transition
Marina Cortês, Andrew R. Liddle
We investigate the parameter space of hybrid inflation models where inflation terminates via a first-order phase transition causing nucleation of bubbles. Such models experience a…
Early assembly of the most massive galaxies
Chris A. Collins, John P. Stott, Matt Hilton +15
The current consensus is that galaxies begin as small density fluctuations in the early Universe and grow by in situ star formation and hierarchical merging. Stars begin to form re…
