In contrast to a conventional wind algorithm, we find that PhEW results are robust to numerical resolution and implementation details because the small scale interactions are defined by the model itself. PhEW adopts an explicit subgrid model that treats each wind particle as a collection of clouds that exchange mass and metals with their surroundings and evaporate by conduction and hydrodynamic instabilities as calibrated on much higher resolution cloud scale simulations.

Simulations with PhEW and conventional winds, these changes in metalĭistribution will affect their predicted UV/X-ray properties inĪbstract = "Although galactic winds play a critical role in regulating galaxy formation, hydrodynamic cosmological simulations do not resolve the scales that govern the interaction between winds and the ambient circumgalactic medium (CGM). While the temperatureĭistributions and radial profiles of gaseous haloes are similar in Unimodal and is similar between cold and hot gas. Particles disperse metals to the ambient medium as their cloudsĭissipate, producing a CGM metallicity distribution that is skewed but PhEW radically alters the CGM metal distribution because PhEW Simulations are in better agreement with low-redshift galactic stellarīecause PhEW particles shed mass to the CGM before escaping low mass Our previous wind simulations with the same resolution, our PhEW Small scale interactions are defined by the model itself.

ESRC recognition for distance learning training in psychological research methods.

Open Psychology Research Centre activities and research support specifically for PhD students.

Phew research series#

Regular School research days and lecture series with distinguished external speakers.

Established record of externally funded research projects, including the European Union the Economic and Social Research Council the Centre for Policing Research and Learning and the National Institute for Health Research.

Research that has real-world relevance and impact and engages with the general public through, among others, open access learning resources and BBC productions.

A thriving interdisciplinary community of researchers with international reputation.

The School of Psychology & Counselling is part of the ESRC Grand Union Doctoral Training Partnership (DTP) with the University of Oxford and Brunel University, and it offers a limited number of doctoral studentships under the Psychology Pathway. Research within the School is conducted under the auspices of the Open Psychology Research Centre, and it is organised around three strands: Culture and Social Psychology (CuSP) Psychology of Health and Wellbeing (PHeW) and the Forensic Cognition Research Group (FCRG). We welcome PhD candidates who aspire to contribute to this ethos through their research. The School of Psychology & Counselling has a vibrant research culture, noted for its transdisciplinary ethos, its real-world relevance and its commitment to social justice.
