Filippenko,Elinor L. Gates,Jenny E. Greene,Weidong Li,Matthew A. Malkan,Richard W. Pogge,Daniel Stern,Tommaso Treu,Jong-Hak Woo +18 more
TL;DR: In this article, the authors present an updated and revised analysis of the relationship between the H{beta} broadline region (BLR) radius and the luminosity of the active galactic nucleus (AGN).
Journal ArticleDOI
Tensions between the early and late Universe
TL;DR: A Kavli Institute for Theoretical Physics workshop in July 2019 directed attention to the Hubble constant discrepancy and proposed solutions focused on the pre-recombination era as mentioned in this paper.
Journal ArticleDOI
The sloan lens acs survey. x. stellar, dynamical, and total mass correlations of massive early-type galaxies
Matthew W. Auger,Tommaso Treu,Adam S. Bolton,Raphael Gavazzi,Raphael Gavazzi,Léon V. E. Koopmans,Philip J. Marshall,Philip J. Marshall,Leonidas A. Moustakas,Scott Burles +9 more
TL;DR: In this paper, the authors used stellar masses, surface photometry, strong-lensing masses, and stellar velocity dispersions (σ e/2) to investigate empirical correlations for the definitive sample of 73 early-type galaxies (ETGs) that are strong gravitational lenses from the SLACS survey.
Journal ArticleDOI
The Sloan Lens ACS Survey. III. The Structure and Formation of Early-Type Galaxies and Their Evolution since z ≈ 1
Léon V. E. Koopmans,Tommaso Treu,Adam S. Bolton,Adam S. Bolton,Scott Burles,Leonidas A. Moustakas +5 more
TL;DR: In this article, a joint likelihood analysis of 15 massive field early-type galaxies selected from the Sloan Lens ACS (SLACS) Survey is presented, and the average position-angle difference between the light distribution and the total mass distribution is found to be = 0 degrees +/- 3 degrees (rms of 10 degrees).
