A surprising consistency between the far-infrared galaxy luminosity functions of the field and Coma (2014)
Journal Article
Hickinbottom, S., Simpson, C., James, P., Ibar, E., Carter, D., Boselli, A., …Valentijn, E. (2014). A surprising consistency between the far-infrared galaxy luminosity functions of the field and Coma. Monthly Notices of the Royal Astronomical Society, 442(2), 1286-1293. https://doi.org/10.1093/mnras/stu924

We present new deep images of the Coma Cluster from the ESA Herschel Space Observatory at wavelengths of 70, 100 and 160 μm, covering an area of 1.75 × 1.0 square degrees encompassing the core and south-west infall region. Our data display an excess... Read More about A surprising consistency between the far-infrared galaxy luminosity functions of the field and Coma.

Variations in the initial mass function in early-type galaxies: a critical comparison between dynamical and spectroscopic results (2014)
Journal Article
Smith, R. J. (2014). Variations in the initial mass function in early-type galaxies: a critical comparison between dynamical and spectroscopic results. Monthly Notices of the Royal Astronomical Society, 443(1), L69-L73. https://doi.org/10.1093/mnrasl/slu082

I present a comparison between published dynamical (ATLAS3D) and spectroscopic (Conroy & van Dokkum) constraints on the stellar initial mass function (IMF) in early-type galaxies, using the 34 galaxies in common between the two works. Both studies in... Read More about Variations in the initial mass function in early-type galaxies: a critical comparison between dynamical and spectroscopic results.

Quenching star formation in cluster galaxies (2014)
Journal Article
Taranu, D. S., Hudson, M. J., Balogh, M. L., Smith, R. J., Power, C., Oman, K. A., & Krane, B. (2014). Quenching star formation in cluster galaxies. Monthly Notices of the Royal Astronomical Society, 440(3), 1934-1949. https://doi.org/10.1093/mnras/stu389

In order to understand the processes that quench star formation in cluster galaxies, we construct a library of subhalo orbits drawn from Λ cold dark matter cosmological N-body simulations of four rich clusters. We combine these orbits with models of... Read More about Quenching star formation in cluster galaxies.

Dissecting the red sequence: the bulge and disc colours of early-type galaxies in the Coma cluster (2014)
Journal Article
Head, J., Lucey, J., Hudson, M., & Smith, R. (2014). Dissecting the red sequence: the bulge and disc colours of early-type galaxies in the Coma cluster. Monthly Notices of the Royal Astronomical Society, 440(2), 1690-1711. https://doi.org/10.1093/mnras/stu325

We explore the internal structure of red-sequence galaxies in the Coma cluster across a wide range of luminosities (−17 > Mg > −22) and cluster-centric radii (0 < rcluster < 1.3 r200). We present the 2D bulge-disc decomposition of galaxies in deep Ca... Read More about Dissecting the red sequence: the bulge and disc colours of early-type galaxies in the Coma cluster.

Barred S0 galaxies in the Coma cluster (2014)
Journal Article
Lansbury, G., Lucey, J., & Smith, R. (2014). Barred S0 galaxies in the Coma cluster. Monthly Notices of the Royal Astronomical Society, 439(2), 1749-1764. https://doi.org/10.1093/mnras/stu049

This study uses r-band images from the Eighth Data Release of the Sloan Digital Sky Survey (SDSS DR8) to study bars in lenticular (S0) galaxies in one of the nearest rich cluster environments, the Coma cluster. We develop techniques for bar detection... Read More about Barred S0 galaxies in the Coma cluster.
