"The probability density function in molecular gas"

Maria Cunningham (UNSW, Sydney)

Abstract
We have undertaken multi-molecular-line surveys of the G333 and Vela C molecular clouds, using the wide-band capabilities of the Mopra telescope. The data sets are being used to investigate the chemistry, kinematics and hierarchical structure of the interstellar medium. In this talk we discuss the probability density function distribution in a range of molecules tracing different critical densities. We show that the chemical and excitation differences between different molecules show up as differences in the PDF for each molecule. The interpretation of the differences in terms of the type of gas traced by different molecules, and how useful each is for tracing gravitationally bound gas and/or gas that is tracing the broader hierarchical structure is discussed.

"Rosetta: the European Space Agency's comet-chasing mission"

Mark McCaughrean (ESA)

Abstract
On 6 August, Rosetta successfully rendezvoused with Comet 67P/Churyumov-Gerasimenko at a distance of more than 400 million km from Earth, marking the beginning of its main science mission. For the first time, Rosetta will escort and study a comet in great detail and at close proximity as it evolves from now until perihelion in August 2015 and beyond, and will deploy a smaller lander, Philae, to the comet's surface in November this year.

I'll give an overview of the scientific goals of this unique mission, the journey taken to reach 67P/C-G, and what to expect over the coming months as the landing site is selected and Philae is deployed. I'll also give a flavour of the early science results from the mission. Finally, I'll discuss some of the successes and pitfalls of our substantial communications and outreach campaign for the mission.

"Modelling Galaxies within state-of-the-art Cosmological Simulations"

Violeta Gonzalez-Perez (University of Durham)

Abstract
Galaxies are thought to form within haloes of dark matter, whose gravity allows the galaxies to exist. The formation and evolution of galaxies is affected by a multitude of other processes besides gravity and computational modelling is the only way we can attempt to understand all these processes. In this work we present a new development of the GALFORM semi-analytical model of galaxy formation and evolution, which exploits a Millennium Simulation-class N-body run performed with the Wilkinson Microwave Anisotropy Probe 7 cosmology. We use this new model to study the impact of the choice of stellar population synthesis (SPS) model on the predicted evolution of the galaxy luminosity function. Besides this model, we have generated a new GALFORM flavour constructed from merger trees derived from EAGLE, a hydrodynamical simulation. We compare results from both GALFORM and EAGLE.
