A Triple Rollover: A third multiply-imaged source at z~6 behind the Jackpot gravitational lens (2020)
Journal Article
Collett, T. E., & Smith, R. J. (2020). A Triple Rollover: A third multiply-imaged source at z~6 behind the Jackpot gravitational lens. Monthly Notices of the Royal Astronomical Society, 497(2), 1654-1660. https://doi.org/10.1093/mnras/staa1804Using a 5-h adaptive-optics-assisted observation with Multi-Unit Spectroscopic Explorer, we have identified a doubly imaged Ly α source at a redshift of 5.975 behind the z = 0.222 lens galaxy J0946+1006 (the ‘Jackpot’). The source separation implies... Read More about A Triple Rollover: A third multiply-imaged source at z~6 behind the Jackpot gravitational lens.
MNELLS: The MUSE Nearby Early-Type Galaxy Lens Locator Survey (2020)
Journal Article
Lucey, J. R., Smith, R. J., & Collier, W. P. (2020). MNELLS: The MUSE Nearby Early-Type Galaxy Lens Locator Survey. Monthly Notices of the Royal Astronomical Society, 494(1), 271-292. https://doi.org/10.1093/mnras/staa602Low-redshift strong-lensing galaxies can provide robust measurements of the stellar mass-to-light ratios in early-type galaxies (ETGs), and hence constrain variations in the stellar initial mass function (IMF). At present, only a few such systems are... Read More about MNELLS: The MUSE Nearby Early-Type Galaxy Lens Locator Survey.
Discovering novae in early-type galaxies with MUSE: A chance find in NGC 1404, and 12 more candidates from an archival search (2020)
Journal Article

Monthly Notices of the Royal Astronomical Society: Letters, 494(1), L1-L5. https://doi.org/10.1093/mnrasl/slaa023I report the discovery of a transient broad-Hα point source in the outskirts of the giant elliptical galaxy NGC 1404, discovered in archival observations taken with the Multi-Unit Spectroscopic Explorer (MUSE) integral field spectrograph. The Hα line... Read More about Discovering novae in early-type galaxies with MUSE: A chance find in NGC 1404, and 12 more candidates from an archival search.
Subaru FOCAS IFU observations of two z=0.12 strong-lensing elliptical galaxies from SDSS MaNGA (2020)
Journal Article
Smith, R. J., Collier, W. P., Ozaki, S., & Lucey, J. R. (2020). Subaru FOCAS IFU observations of two z=0.12 strong-lensing elliptical galaxies from SDSS MaNGA. Monthly Notices of the Royal Astronomical Society: Letters, 493(1), L33-L38. https://doi.org/10.1093/mnrasl/slaa003We present new observations of two z = 0.12 strong-lensing elliptical galaxies, originally discovered from the SDSS-IV MaNGA survey, using the new FOCAS IFU spectrograph on the Subaru Telescope. For J1436+4943, our observations confirm the identifica... Read More about Subaru FOCAS IFU observations of two z=0.12 strong-lensing elliptical galaxies from SDSS MaNGA.
