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…
Microlensing of Microlensing: Effects of Random Stars on the Double-Source-Plane Gravitational Lens
Nada Salama, Daniel J. Ballard, Huimin Qu +2
Microlensing, the influence of stars within a galactic gravitational lens, has emerged as a powerful probe of compact mass and, through differential magnification, sub-parsec scale…
A Salpeter IMF and an NFW halo: Disentangling the dark and stellar mass of an elliptical galaxy through precise lens modelling of a double-source-plane system
Tian Li, Thomas E. Collett, Coleman M. Krawczyk +7
We present a strong lensing analysis of the double source plane lens J0946+1006 (colloquially "Jackpot" lens) to measure the inner dark matter density profile, the stellar-to-halo…
Multi-band Reconstruction of Sixteen Gravitational Lens Systems using PISCO data
Huimin Qu, Daniel J. Ballard, Geraint F. Lewis +12
Next-generation surveys such as the Euclid survey, the Legacy Survey of Space and Time (LSST), and the China Space Station Telescope (CSST) survey are expected to discover ~10^5 ga…
The Carousel Lens I: A Spectroscopic Survey of the Carousel Lens Field
Jackson H. O'Donnell, Demetrius Y. Williams, Tesla E. Jeltema +18
We present a spectroscopic survey of field galaxies and lensed sources in the vicinity of the strong lensing galaxy cluster known as the Carousel lens at z=0.49. Using both Gemini/…
Constraining Cosmology with Double-source-plane Strong Gravitational Lenses from the AGEL Survey
Duncan J. Bowden, Nandini Sahu, Anowar J. Shajib +17
Double-source-plane strong gravitational lenses (DSPLs), with two sources at different redshifts, are independent cosmological probes of the dark energy equation of state parameter…
Cosmography with the Double Source Plane Strong Gravitational Lens AGEL150745+052256
Nandini Sahu, Anowar J. Shajib, Kim-Vy Tran +14
Strong gravitational lenses with two background sources at widely separated redshifts are a powerful and independent probe of cosmological parameters. We can use these systems, kno…
The AGEL Survey Data Release 2: A Gravitational Lens Sample for Galaxy Evolution and Cosmology
Tania M. Barone, Keerthi Vasan G. C., Kim-Vy Tran +31
The ASTRO 3D Galaxy Evolution with Lenses (AGEL) Survey is an ongoing effort to spectroscopically confirm a diverse sample of gravitational lenses with high spatial resolution imag…
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…
Correcting for Selection Biases in the Determination of the Hubble Constant from Time-Delay Cosmography
Tian Li, Thomas E. Collett, Philip J. Marshall +4
The time delay between multiple images of strongly lensed quasars has been used to infer the Hubble constant. The primary systematic uncertainty for time-delay cosmography is the m…
Gravitational imaging through a triple source plane lens: revisiting the CDM-defying dark subhalo in SDSSJ0946+1006
Daniel J. Ballard, Wolfgang J. R. Enzi, Thomas E. Collett +2
The CDM paradigm successfully explains the large-scale structure of the Universe, but is less well constrained on sub-galactic scales. Gravitational lens modelling has been used…
