'Ultraluminous X-ray sources and their implications'
Lead Research Organisation:
Durham University
Department Name: Physics
Abstract
'Ultraluminous X-ray sources (ULXs) are not just intense emitters of X-rays; it now appears certain that they also power strong winds. A combination of their energetic radiation and powerful winds will have a severe impact on their near environments, and has led to the formation of bubble nebulae around several nearby examples. In this project we will obtain the best possible observational constraints on the impacts of ULXs on their environments, and seek to understand how these objects may have influenced the development of nascent galaxies at epochs when ULXs were likely to have been far more plentiful than in the current era.'

Results and Impact | Approximately 30 people attended an outreach event held in a local pub in Durham to learn about the research activities undertaken in various regional institutions, including the Department of Physics and the Institute for Computational Cosmology. The event included talks from graduate and postgraduate students, who presented their research to the general audience in a visually engaging manner, which was supported by the use of exhibits such as a "galaxy movie maker", and several other innovative displays. |

Results and Impact | I participated in an event that aimed to communicate research undertaken in the Institute for Computational Cosmology to the general public. This was done through exhibits that showed animations of the structure formation of the universe, and also included an interactive simulation of galaxy formation. I interacted with people of a wide variety of ages and backgrounds, and explained the basic (physical) principles behind each exhibit. I was happy that the event garnered a lot of questions and enthusiasm, especially from children. |
