We present six new time-delay measurements obtained from Rc-band monitoring data acquired at the Max Planck Institute for Astrophysics (MPIA) 2.2 m telescope at La Silla observatory between October 2016 and February 2020. The lensed quasars HE 0047−1... Read More about TDCOSMO: II. Six new time delays in lensed quasars from high-cadence monitoring at the MPIA 2.2 m telescope.

Measurement of peculiar velocities by combining redshifts and distance indicators is a powerful way to measure the growth rate of a cosmic structure and test theories of gravity at low redshift. Here we constrain the growth rate of the structure by c... Read More about Joint analysis of 6dFGS and SDSS peculiar velocities for the growth rate of cosmic structure and tests of gravity.

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/staa602

Low-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.

Subaru FOCAS IFU observations of two z=0.12 strong-lensing elliptical galaxies from SDSS MaNGA (2020)
Journal Article

We 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.
