Journal Article
Scrimgeour, M. I., Davis, T. M., Blake, C., Staveley-Smith, L., Magoulas, C., Springob, C. M., …Poole, G. B. (2016). The 6dF Galaxy Survey: Bulk Flows on 50−70h−1 Mpc scales. Monthly Notices of the Royal Astronomical Society, 455(1), 386-401. https://doi.org/10.1093/mnras/stv2146

We measure the bulk flow of the local Universe using the 6dF Galaxy Survey peculiar velocity sample (6dFGSv), the largest and most homogeneous peculiar velocity sample to date. 6dFGSv is a Fundamental Plane sample of ∼104 peculiar velocities covering...

The IMF-sensitive 1.14-μm Na i doublet in early-type galaxies (2015)
Journal Article
Smith, R. J., Alton, P. D., Lucey, J. R., Conroy, C., & Carter, D. (2015). The IMF-sensitive 1.14-μm Na i doublet in early-type galaxies. Monthly Notices of the Royal Astronomical Society: Letters, 454(1), L71-L75. https://doi.org/10.1093/mnrasl/slv132

We present J-band spectroscopy of passive galaxies focusing on the Na i doublet at 1.14 μm. Like the Na i 0.82 μm doublet, this feature is strong in low-mass stars and hence may provide a useful probe of the initial mass function (IMF). From high sig...

Beyond Sérsic + exponential disc morphologies in the Coma Cluster (2015)
Journal Article
Head, J. T., Lucey, J. R., & Hudson, M. J. (2015). Beyond Sérsic + exponential disc morphologies in the Coma Cluster. Monthly Notices of the Royal Astronomical Society, 453(4), 3730-3753. https://doi.org/10.1093/mnras/stv1662

Galaxies are not limited to simple spheroid or bulge + disc morphologies. We explore the diversity of internal galaxy structures in the Coma Cluster across a wide range of luminosities (−17 > Mg > −22) and cluster-centric radii (0 < rcluster < 1.3r20...

Modified gravity and large scale flows (2015)
Journal Article
Mould, J., Colless, M., Erdoğdu, P., Jones, H., Lucey, J., Ma, Y., …Springob, C. M. (2015). Modified gravity and large scale flows. Astrophysics and Space Science, 357(2), Article 162. https://doi.org/10.1007/s10509-015-2351-2

Reconstruction of the local velocity field from the overdensity field and a gravitational acceleration that falls off from a point mass as r −2 yields velocities in broad agreement with peculiar velocities measured with galaxy distance indicators. MO... Read More about Modified gravity and large scale flows.

The SINFONI Nearby Elliptical Lens Locator Survey: discovery of two new low-redshift strong lenses and implications for the initial mass function in giant early-type galaxies (2015)
Journal Article
Smith, R., Lucey, J., & Conroy, C. (2015). The SINFONI Nearby Elliptical Lens Locator Survey: discovery of two new low-redshift strong lenses and implications for the initial mass function in giant early-type galaxies. Monthly Notices of the Royal Astronomical Society, 449(4), 3441-3457. https://doi.org/10.1093/mnras/stv518

We present results from a blind survey to identify strong gravitational lenses among the population of low-redshift early-type galaxies. The SINFONI Nearby Elliptical Lens Locator Survey (SNELLS) uses integral-field infrared spectroscopy to search fo...
