LSST Science Book, Version 2.0
LSST Science Collaboration, Paul A. Abell, Julius Allison +245
A survey that can cover the sky in optical bands over wide fields to faint magnitudes with a fast cadence will enable many of the exciting science opportunities of the next decade.…
Cosmic Evolution of Virial and Stellar Mass in Massive Early-Type Galaxies
David J. Lagattuta, Christopher D. Fassnacht, Matthew W. Auger +7
We measure the average mass properties of a sample of 41 strong gravitational lenses at moderate redshift (z ~ 0.4 - 0.9), and present the lens redshift for 6 of these galaxies for…
Focusing Cosmic Telescopes: Exploring Redshift z~5-6 Galaxies with the Bullet Cluster 1E0657-56
M. Bradač, T. Treu, D. Applegate +7
The gravitational potential of clusters of galaxies acts as a cosmic telescope allowing us to find and study galaxies at fainter limits than otherwise possible and thus probe close…
Dissecting the Gravitational Lens B1608+656. II. Precision Measurements of the Hubble Constant, Spatial Curvature, and the Dark Energy Equation of State
S. H. Suyu, P. J. Marshall, M. W. Auger +5
Strong gravitational lens systems with measured time delays between the multiple images provide a method for measuring the "time-delay distance" to the lens, and thus the Hubble co…
The Distribution of Dark Matter Over 3 Decades in Radius in the Lensing Cluster Abell 611
A. B. Newman, T. Treu, R. S. Ellis +5
We present a detailed analysis of the baryonic and dark matter distribution in the lensing cluster Abell 611 (z=0.288), with the goal of determining the dark matter profile over an…
The Quasar SDSS J105041.35+345631.3: Black Hole Recoil or Extreme Double-Peaked Emitter?
G. A. Shields, D. J. Rosario, K. L. Smith +8
The quasar SDSS J105041.35+345631.3 (z = 0.272) has broad emission lines blueshifted by 3500 km/s relative to the narrow lines and the host galaxy. Such an object may be a candidat…
Dark Matter Structures in the Universe: Prospects for Optical Astronomy in the Next Decade
P. J. Marshall, M. Auger, J. G. Bartlett +13
The Cold Dark Matter theory of gravitationally-driven hierarchical structure formation has earned its status as a paradigm by explaining the distribution of matter over large spans…
