Gaia GraL: Gaia DR2 Gravitational Lens Systems. V. Doubly-imaged QSOs discovered from entropy and wavelets
A. Krone-Martins, M. J. Graham, D. Stern +22
The discovery of multiply-imaged gravitationally lensed QSOs is fundamental to many astronomical and cosmological studies. However, these objects are rare and challenging to discov…
Stars made in outflows may populate the stellar halo of the Milky Way
Sijie Yu, James S. Bullock, Andrew Wetzel +8
We study stellar-halo formation using six Milky Way-mass galaxies in FIRE-2 cosmological zoom simulations. We find that of the outer ( kpc) stellar halo in each sy…
Constraints on the mass-concentration relation of cold dark matter halos with 11 strong gravitational lenses
Daniel Gilman, Xiaolong Du, Andrew Benson +3
The mass-concentration relation of dark matter halos reflects the assembly history of objects in hierarchical structure formation scenarios, and depends on fundamental quantities i…
Warm dark matter chills out: constraints on the halo mass function and the free-streaming length of dark matter with 8 quadruple-image strong gravitational lenses
Daniel Gilman, Simon Birrer, Anna Nierenberg +3
The free-streaming length of dark matter depends on fundamental dark matter physics, and determines the abundance and concentration of dark matter halos on sub-galactic scales. Usi…
Double dark matter vision: twice the number of compact-source lenses with narrow-line lensing and the WFC3 grism
A. M. Nierenberg, D. Gilman, T. Treu +9
The magnifications of compact-source lenses are extremely sensitive to the presence of low mass dark matter halos along the entire sight line from the source to the observer. Tradi…
Astro2020 Science White Paper - Quasar Microlensing: Revolutionizing our Understanding of Quasar Structure and Dynamics
Leonidas Moustakas, Matthew O'Dowd, Timo Anguita +20
Microlensing by stars within distant galaxies acting as strong gravitational lenses of multiply-imaged quasars, provides a unique and direct measurement of the internal structure o…
The Detailed Science Case for the Maunakea Spectroscopic Explorer, 2019 edition
The MSE Science Team, Carine Babusiaux, Maria Bergemann +258
(Abridged) The Maunakea Spectroscopic Explorer (MSE) is an end-to-end science platform for the design, execution and scientific exploitation of spectroscopic surveys. It will unvei…
Astrophysical Tests of Dark Matter with Maunakea Spectroscopic Explorer
Ting S. Li, Manoj Kaplinghat, Keith Bechtol +27
We discuss how astrophysical observations with the Maunakea Spectroscopic Explorer (MSE), a high-multiplexity (about 4300 fibers), wide field-of-view (1.5 square degree), large tel…
Detecting Dark Matter Cores in Galaxy Clusters with Strong Lensing
Kevin E. Andrade, Quinn Minor, Anna Nierenberg +1
We test the ability of strong lensing data to constrain the size of a central core in the dark matter halos of galaxy clusters, using Abell 611 as a prototype. Using simulated data…
Probing dark matter structure down to solar masses: flux ratio statistics in gravitational lenses with line of sight halos
Daniel Gilman, Simon Birrer, Tommaso Treu +2
Strong lensing provides a powerful means of investigating the nature of dark matter as it probes dark matter structure on sub-galactic scales. We present an extension of a forward…
