Dark Matter Contraction and the Stellar Content of Massive Early-type Galaxies: Disfavoring 'Light' Initial Mass Functions
Matthew W. Auger,Tommaso Treu,Raphael Gavazzi,Adam S. Bolton,Léon V. E. Koopmans,Philip J. Marshall +5 more
TL;DR: In this paper, the authors use stellar dynamics, strong lensing, stellar population synthesis models, and weak lensing shear measurements to constrain the dark matter profile and stellar mass in a sample of 53 massive early-type galaxies.
The SWELLS survey – II. Breaking the disc–halo degeneracy in the spiral galaxy gravitational lens SDSS J2141−0001
Aaron A. Dutton,Aaron A. Dutton,Brendon J. Brewer,Philip J. Marshall,Philip J. Marshall,Matthew W. Auger,Tommaso Treu,David C. Koo,Adam S. Bolton,Bradford P. Holden,Léon V. E. Koopmans +10 more
TL;DR: In this paper, the authors presented an analysis of the strong gravitational lens SDSS J2141-0001, discovered as part of the Sloan Lens ACS survey, using information from gravitational lensing and gas kinematics.
The Grism Lens-Amplified Survey from Space (GLASS) – XIII. G800L optical spectra from the parallel fields
L. E. Abramson,L. E. Abramson,L. E. Abramson,Gabriel B. Brammer,Gabriel B. Brammer,Kasper B. Schmidt,Tommaso Treu,T. Morishita,Xin Wang,Benedetta Vulcani,Alaina Henry +10 more
TL;DR: In this article, the authors presented a catalogue of 22755 objects with slitless, optical, Hubble Space Telescope (HST) spectroscopy from the Grism Lens-Amplified Survey from Space (GLASS).
Constraints on the broad line region from regularized linear inversion: velocity–delay maps for five nearby active galactic nuclei
A. Skielboe,Anna Pancoast,Tommaso Treu,Tommaso Treu,Daeseong Park,Aaron J. Barth,Misty C. Bentz +6 more
TL;DR: Skielboe et al. as discussed by the authors used regularized linear inversion (RLI) to model the AGN continuum light curves to constrain the broad emission-line region (BLR) structure.
The Sloan Lens ACS Survey. VI: Discovery and analysis of a double Einstein ring
Raphael Gavazzi,Tommaso Treu,Léon V. E. Koopmans,Adam S. Bolton,Adam S. Bolton,Leonidas A. Moustakas,Scott Burles,Philip J. Marshall +7 more
TL;DR: In this paper, two concentric Einstein rings around the SDSSJ0946+1006 were discovered as part of the Sloan Lens ACS Survey and used to constrain cosmological parameters exploiting angular distance ratios entering the lens equations.
