Harnessing stellar kinematics to constrain dark energy with the double-source-plane gravitational lens SDSS J0946+1006
Daniel J. Ballard, Wolfgang J. R. Enzi, Thomas E. Collett +6
SDSS J0946+1006 is an attractive target for measuring cosmological parameters through lens modelling. It is the best-studied galaxy-scale strong gravitational lens with multiple so…
The overconcentrated dark halo in the strong lens SDSS J0946+1006 is a subhalo: evidence for self interacting dark matter?
Wolfgang J. R. Enzi, Coleman M. Krawczyk, Daniel J. Ballard +1
The nature of dark matter is poorly constrained on subgalactic scales. Alternative models to cold dark matter, such as warm dark matter or self-interacting dark matter, could produ…
Cosmology from Large Populations of Galaxy-Galaxy Strong Gravitational Lenses
Tian Li, Thomas E. Collett, Coleman M. Krawczyk +1
We present a forecast analysis on the feasibility of measuring the cosmological parameters with a large number of galaxy-galaxy scale strong gravitational lensing systems. Future w…
Lensed type Ia supernovae in light of SN Zwicky and iPTF16geu
Ana Sainz de Murieta, Thomas E. Collett, Mark R. Magee +3
Strong gravitationally lensed supernovae (glSNe) are a powerful probe to obtain a measure of the expansion rate of the Universe, but they are also extremely rare. To date, only two…
Mean Spectral Energy Distributions and Bolometric Corrections for Luminous Quasars
Coleman M. Krawczyk, Gordon T. Richards, Sajjan S. Mehta +5
We explore the mid-infrared (mid-IR) through ultraviolet (UV) spectral energy distributions (SEDs) of 119,652 luminous broad-lined quasars with 0.064<z<5.46 using mid-IR data from…
CIV Emission and the Ultraviolet through X-ray Spectral Energy Distribution of Radio-Quiet Quasars
Nicholas E. Kruczek, Gordon T. Richards, S. C. Gallagher +6
In the restframe UV, two of the parameters that best characterize the range of emission-line properties in quasar broad emission-line regions are the equivalent width and the blues…
