First Light And Reionisation Epoch Simulations (FLARES) VIII. The Emergence of Passive Galaxies at

Christopher C. Lovell, Will Roper, Aswin P. Vijayan +9

Passive galaxies are ubiquitous in the local universe, and various physical channels have been proposed that lead to this passivity. To date, robust passive galaxy candidates have…

Robust topological oscillators govern a tunable phase transition to synchronized circadian rhythms

Chongbin Zheng, Peter Thomas, Evelyn Tang

The paper proposes a mechanism by which stochastic circadian KaiC proteins, which follow topologically protected cycles, can synchronize through a phase transition that depends on…

Simulating Supernovae Remnants in Gas Clouds

Simon Goodwin, Frazer Pearce, Peter Thomas

The Hydra -body hydrodynamics code has been modified to model, from the end of the Sedov phase, the effects of supernovae on the surrounding medium. The motivation is to investi…

Nebular Line Emission During the Epoch of Reionization

Stephen M. Wilkins, Christopher C. Lovell, Ciaran Fairhurst +6

Nebular emission lines associated with galactic HII regions carry information about both physical properties of the ionised gas and the source of ionising photons as well as provid…

Galaxy and Mass Assembly (GAMA): halo formation times and halo assembly bias on the cosmic web

Rita Tojeiro, Elizabeth Eardley, John A. Peacock +10

We present evidence for halo assembly bias as a function of geometric environment. By classifying GAMA galaxy groups as residing in voids, sheets, filaments or knots using a tidal…

Eye Gaze Controlled Interfaces for Head Mounted and Multi-Functional Displays in Military Aviation Environment

LRD Murthy, Abhishek Mukhopadhyay, Varshit Yellheti +6

Eye gaze controlled interfaces allow us to directly manipulate a graphical user interface just by looking at it. This technology has great potential in military aviation, in partic…

The Lyman-continuum photon production efficiency in the high-redshift Universe

Stephen M. Wilkins, Yu Feng, Tiziana Di Matteo +4

The Lyman Continuum photon production efficiency () is a critical ingredient for inferring the number of photons available to reionise the intergalactic medium. To es…

Galaxy formation in the PLANCK cosmology - III. The high-redshift universe

Scott Clay, Peter Thomas, Stephen Wilkins +1

We present high-redshift predictions of the star-formation-rate distribution function (SFR DF), UV luminosity function (UV LF), galactic stellar mass function (GSMF), and specific…

Simulating the joint evolution of quasars, galaxies and their large-scale distribution

Volker Springel, Simon D. M. White, Adrian Jenkins +14

The cold dark matter model has become the leading theoretical paradigm for the formation of structure in the Universe. Together with the theory of cosmic inflation, this model make…
