"Upper-limit lensing": constraining galaxy stellar masses with singly imaged background sources (2018)
Journal Article
Smith, R. J., Lucey, J. R., & Collier, W. P. (2018). "Upper-limit lensing": constraining galaxy stellar masses with singly imaged background sources. Monthly Notices of the Royal Astronomical Society, 481(2), 2115-2124. https://doi.org/10.1093/mnras/sty2328

Strong gravitational lensing can provide accurate measurements of the stellar mass-to-light ratio Υ in low-redshift (z ≲ 0.05) early-type galaxies, and hence probe for possible variations in the stellar initial mass function (IMF). However, true mult... Read More about "Upper-limit lensing": constraining galaxy stellar masses with singly imaged background sources.

KINETyS II: Constraints on spatial variations of the stellar initial mass function from K-band spectroscopy (2018)
Journal Article
Alton, P., Smith, R., & Lucey, J. (2018). KINETyS II: Constraints on spatial variations of the stellar initial mass function from K-band spectroscopy. Monthly Notices of the Royal Astronomical Society, 478(4), 4464-4486. https://doi.org/10.1093/mnras/sty1242

We investigate the spatially resolved stellar populations of a sample of seven nearby massive Early-type galaxies (ETGs), using optical and near infrared data, including K-band spectroscopy. This data offers good prospects for mitigating the uncertai... Read More about KINETyS II: Constraints on spatial variations of the stellar initial mass function from K-band spectroscopy.

A new strong-lensing galaxy at z=0.066: Another elliptical galaxy with a lightweight IMF (2018)
Journal Article
Collier, W. P., Smith, R. J., & Lucey, J. R. (2018). A new strong-lensing galaxy at z=0.066: Another elliptical galaxy with a lightweight IMF. Monthly Notices of the Royal Astronomical Society, 478(2), 1595-1600. https://doi.org/10.1093/mnras/sty1188

We report the discovery of a new low-redshift galaxy-scale gravitational lens, identified from a systematic search of publicly available MUSE observations. The lens galaxy, 2MASXJ04035024-0239275, is a giant elliptical at z = 0.06604 with a velocity...

Serendipitous discovery of quadruply imaged quasars: two diamonds (2018)
Journal Article
Lucey, J. R., Schechter, P. L., Smith, R. J., & Anguita, T. (2018). Serendipitous discovery of quadruply imaged quasars: two diamonds. Monthly Notices of the Royal Astronomical Society, 476(1), 927-932. https://doi.org/10.1093/mnras/sty243

Gravitationally lensed quasars are powerful and versatile astrophysical tools, but they are challengingly rare. In particular, only ∼25 well-characterized quadruple systems are known to date. To refine the target catalogue for the forthcoming Taipan... Read More about Serendipitous discovery of quadruply imaged quasars: two diamonds.

The most massive black holes on the Fundamental Plane of black hole accretion (2017)
Journal Article
Mezcua, M., Hlavacek-Larrondo, J., Lucey, J., Hogan, M., Edge, A., & McNamara, B. (2018). The most massive black holes on the Fundamental Plane of black hole accretion. Monthly Notices of the Royal Astronomical Society, 474(1), 1342-1360. https://doi.org/10.1093/mnras/stx2812

We perform a detailed study of the location of brightest cluster galaxies (BCGs) on the Fundamental Plane of black hole (BH) accretion, which is an empirical correlation between a BH X-ray and radio luminosity and mass supported by theoretical models...

The Taipan Galaxy Survey: Scientific Goals and Observing Strategy (2017)
Journal Article
da Cunha, E., Hopkins, A. M., Colless, M., Taylor, E. N., Blake, C., Howlett, C., …Watson, F. (2017). The Taipan Galaxy Survey: Scientific Goals and Observing Strategy. Publications of the Astronomical Society of Australia, 34, Article e047. https://doi.org/10.1017/pasa.2017.41

The Taipan galaxy survey (hereafter simply ‘Taipan’) is a multi-object spectroscopic survey starting in 2017 that will cover 2π steradians over the southern sky (δ ≲ 10°, |b| ≳ 10°), and obtain optical spectra for about two million galaxies out to z...

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.
