The duration of reionization constrains the ionizing sources
Mahavir Sharma, Tom Theuns, Carlos Frenk
We investigate how the nature of the galaxies that reionized the Universe affects the duration of reionization. We contrast two sets of models: one in which galaxies on the faint s…
CEMPlifying reionization
Mahavir Sharma, Tom Theuns, Carlos Frenk
The massive stars that ionised the Universe have short lifetimes and can only be studied near the time of formation, but any low mass stars that formed contemporaneously might be o…
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…
The Cluster-EAGLE project: velocity bias and the velocity dispersion - mass relation of cluster galaxies
Thomas Joshua Armitage, David. J. Barnes, Scott. T. Kay +4
We use the Cluster-EAGLE simulations to explore the velocity bias introduced when using galaxies, rather than dark matter particles, to estimate the velocity dispersion of a galaxy…
Reducing biases on measurements using strong lensing and galaxy dynamics: results from the EAGLE simulation
Amitpal S. Tagore, David J. Barnes, Neal Jackson +4
Cosmological parameter constraints from observations of time-delay lenses are becoming increasingly precise. However, there may be significant bias and scatter in these measurement…
