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.

Non-equilibrium chemistry and cooling in the diffuse interstellar medium - I. Optically thin regime (2014)
Journal Article
Richings, A. J., Schaye, J., & Oppenheimer, B. D. (2014). Non-equilibrium chemistry and cooling in the diffuse interstellar medium - I. Optically thin regime. Monthly notices of the Royal Astronomical Society, 440(4), 3349-3369. https://doi.org/10.1093/mnras/stu525

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...

The connection between radio loudness and central surface brightness profiles in optically selected low-luminosity active galaxies (2011)
Journal Article
Richings, A. J., Uttley, P., & Körding, E. (2011). The connection between radio loudness and central surface brightness profiles in optically selected low-luminosity active galaxies. Monthly notices of the Royal Astronomical Society, 415(3), 2158-2172. https://doi.org/10.1111/j.1365-2966.2011.18845.x

Recent results indicate a correlation between nuclear radio loudness of active galaxies and their central stellar surface-brightness profiles, in that 'core' galaxies (with inner logarithmic slope γ≤ 0.3) are significantly more radio loud than 'power...

Field and globular cluster low-mass X-ray binaries in NGC 4278 (2010)
Journal Article
Fabbiano, G., Brassington, N. J., Lentati, L., Angelini, L., Davies, R. L., Gallagher, J., …Zepf, S. (2010). Field and globular cluster low-mass X-ray binaries in NGC 4278. The Astrophysical journal, 725(2), 1824-1847. https://doi.org/10.1088/0004-637X/725/2/1824

We report a detailed spectral analysis of the population of low-massX-ray binaries (LMXBs) detected in the elliptical galaxy NGC 4278 with Chandra. Seven luminous sources were studied individually, four in globular clusters (GCs) and three in the ste... Read More about Field and globular cluster low-mass X-ray binaries in NGC 4278.
