Improved mass constraints for two nearby strong-lensing elliptical galaxies from Hubble Space Telescope Imaging (2017)
Journal Article
Collier, W. P., Smith, R. J., & Lucey, J. R. (2017). Improved mass constraints for two nearby strong-lensing elliptical galaxies from Hubble Space Telescope Imaging. Monthly Notices of the Royal Astronomical Society, 473(1), 1103-1107. https://doi.org/10.1093/mnras/stx2297

We analyse newly obtained Hubble Space Telescope (HST) imaging for two nearby strong lensing elliptical galaxies, SNL-1 (z = 0.03) and SNL-2 (z = 0.05), in order to improve the lensing mass constraints. The imaging reveals previously unseen structure... Read More about Improved mass constraints for two nearby strong-lensing elliptical galaxies from Hubble Space Telescope Imaging.

The Initial Mass Function in the Nearest Strong Lenses from SNELLS: Assessing the Consistency of Lensing, Dynamical, and Spectroscopic Constraints (2017)

The Initial Mass Function in the Nearest Strong Lenses from SNELLS: Assessing the Consistency of Lensing, Dynamical, and Spectroscopic Constraints. Astrophysical Journal, 845(2), Article 157. https://doi.org/10.3847/1538-4357/aa816d

We present new observations of the three nearest early-type galaxy (ETG) strong lenses discovered in the SINFONI Nearby Elliptical Lens Locator Survey (SNELLS). Based on their lensing masses, these ETGs were inferred to have a stellar initial mass fu...

We present the serendipitous discovery of an extended cold gas structure projected close to the brightest cluster galaxy (BCG) of the z = 0.045 cluster Abell 3716, from archival integral field spectroscopy. The gas is revealed through narrow Na D lin... Read More about An extended cold gas absorber in a central cluster galaxy.

Stellar dynamics in the strong-lensing central galaxy of Abell 1201: a low stellar mass-to-light ratio, a large central compact mass and a standard dark matter halo (2017)
Journal Article

Stellar dynamics in the strong-lensing central galaxy of Abell 1201: a low stellar mass-to-light ratio, a large central compact mass and a standard dark matter halo. Monthly Notices of the Royal Astronomical Society, 471(1), 383-393. https://doi.org/10.1093/mnras/stx1573

We analyse the stellar kinematics of the z = 0.169 brightest cluster galaxy in Abell 1201, using integral field observations acquired with the Multi-Unit Spectroscopic Explorer on the Very Large Telescope. This galaxy has a gravitationally lensed arc...

KINETyS: Constraining spatial variations of the stellar initial mass function in early-type galaxies (2017)
Journal Article

The heavyweight stellar initial mass function (IMF) observed in the cores of massive early-type galaxies (ETGs) has been linked to formation of their cores in an initial swiftly quenched rapid starburst. However, the outskirts of ETGs are thought to... Read More about KINETyS: Constraining spatial variations of the stellar initial mass function in early-type galaxies.

A counter-image to the gravitational arc in Abell 1201: Evidence for IMF variations, or a 10^10 M⊙ black hole? (2017)
Journal Article

Abell 1201 is a massive galaxy cluster at z=0.169 with a brightest cluster galaxy (BCG) that acts as a gravitational lens to a background source at z=0.451. The lensing configuration is unusual, with a single bright arc formed at small radius (∼2 arc...
