Journal Article
Penny, S. J., Forbes, D. A., Pimbblet, K. A., & Floyd, D. J. E. (2014). Dwarf galaxies in the Perseus Cluster: further evidence for a disc origin for dwarf ellipticals. Monthly notices of the Royal Astronomical Society, 443(4), 3381-3387. https://doi.org/10.1093/mnras/stu1397

We present the results of a Keck-ESI (Echellette Spectrograph and Imager) spectroscopic study of six dwarf elliptical (dE) galaxies in the Perseus Cluster core, and confirm two dwarfs as cluster members for the first time. All six dEs follow the size... Read More about Dwarf galaxies in the Perseus Cluster: further evidence for a disc origin for dwarf ellipticals.

Non-equilibrium chemistry and cooling in the diffuse interstellar medium - II. Shielded gas (2014)
Journal Article
Richings, A. J., Schaye, J., & Oppenheimer, B. D. (2014). Non-equilibrium chemistry and cooling in the diffuse interstellar medium - II. Shielded gas. Monthly notices of the Royal Astronomical Society, 442(3), 2780-2796. https://doi.org/10.1093/mnras/stu1046

We extend the non-equilibrium model for the chemical and thermal evolution of diffuse interstellar gas presented in Richings et al. to account for shielding from the UV radiation field. We attenuate the photochemical rates by dust and by gas, includi... Read More about Non-equilibrium chemistry and cooling in the diffuse interstellar medium - II. Shielded gas.

We present integral field spectroscopy of 10 early-type galaxies in the nearby, low-mass, Fornax cluster, from which we derive spatially resolved stellar kinematics. Based on the morphologies of their stellar velocity maps we classify 2/10 galaxies a... Read More about Distribution of slow and fast rotators in the Fornax cluster.

An accurate treatment of the multiphase interstellar medium (ISM) in hydrodynamic galaxy simulations requires that we follow not only the thermal evolution of the gas, but also the evolution of its chemical state, including its molecular chemistry, w...

Based on data from the Galaxy and Mass Assembly (GAMA) survey, we report on the discovery of structures that we refer to as ‘tendrils’ of galaxies: coherent, thin chains of galaxies that are rooted in filaments and terminate in neighbouring filaments...

Coma is frequently used as the archetype z ∼ 0 galaxy cluster to compare higher redshift work against. It is not clear, however, how representative the Coma cluster is for galaxy clusters of its mass or X-ray luminosity, and significantly, recent wor... Read More about How typical is the Coma cluster?.
