An overview of stray light findings and interpretation during on-sky commissioning of LSSTCam
Gabriele Rodeghiero, Alex Drlica-Wagner, Alessio Taranto +78
Wide-field telescopes are intrinsically difficult to shield from unwanted stray and scattered light, while the search to identify sources of contaminating light is frequently a cha…
Modeling of the diffuse background produced by the Vera C. Rubin Observatory M2 baffle scattered light
Alessio Taranto, Gabriele Rodeghiero, Luca Rosignoli +58
The Vera C. Rubin Observatory, with its unprecedented field of view and fast focal ratio, will survey the entire sky every 3.5 nights. This unique capacity requires dealing with of…
COOL-LAMPS IX: A Rare Duo of Quasars Each Lensed by a Single Massive Galaxy Cluster
Erik Solhaug, Michael D. Gladders, Andi M. Kisare +20
Wide-separation lensed quasars (WSLQs) are rare systems that arise from the chance alignment of two objects: a galaxy cluster and a background quasar. After two decades, only seven…
The Vera C. Rubin Observatory Data Preview 1
Vera C Rubin Observatory Team, Tatiana Acero Cuellar, Emily Acosta +325
We present Rubin Data Preview 1 DP1, the first data from the NSF DOE Vera C Rubin Observatory, comprising raw and calibrated single epoch images, coadds, difference images, detecti…
Investigating the Dark Energy Constraint from Strongly Lensed AGN at LSST-Scale
Sydney Erickson, Martin Millon, Padmavathi Venkatraman +12
Strongly lensed Active Galactic Nuclei (AGN) with an observable time delay can be used to constrain the expansion history of the Universe through time-delay cosmography (TDC). As t…
The z=1.03 Merging Cluster SPT-CL J0356-5337: New Strong Lensing Analysis with HST and MUSE
Grace Smith, Guillaume Mahler, Kate Napier +8
We present a strong lensing analysis and reconstruct the mass distribution of SPT-CL J0356-5337, a galaxy cluster at redshift z = 1.034. Our model supersedes previous models by mak…
COOL-LAMPS VIII: Known wide-separation lensed quasars and their host galaxies reveal a lack of evolution in since
Aidan P. Cloonan, Gourav Khullar, Kate A. Napier +36
Wide-separation lensed quasars (WSLQs) are a rare class of strongly lensed quasars, magnified by foreground massive galaxy clusters, with typically large magnifications of the mult…
COOL-LAMPS VI: Lens model and New Constraints on the Properties of COOL J1241+2219, a Bright z = 5 Lyman Break Galaxy and its z = 1 Cluster Lens
Maxwell Klein, Keren Sharon, Kate Napier +20
We present a strong lensing analysis of COOL J1241+2219, the brightest known gravitationally lensed galaxy at , based on new multi-band Hubble Space Telescope (HST) imagi…
COOL-LAMPS. V. Discovery of COOL J03351927, a Gravitationally Lensed Quasar at =3.27 with an Image Separation of 23.3"
Kate Napier, Mike Gladders, Keren Sharon +18
We report the discovery of COOL J03351927, a quasar at z = 3.27 lensed into three images with a maximum separation of 23.3" by a galaxy cluster at z = 0.4178. To date this is th…
Small Region, Big Impact: Highly Anisotropic Lyman-continuum Escape from a Compact Starburst Region with Extreme Physical Properties
Keunho J. Kim, Matthew B. Bayliss, Jane R. Rigby +13
Extreme, young stellar populations are considered the primary contributor to cosmic re-ionization. How Lyman-continuum (LyC) escapes these galaxies remains highly elusive, and it i…
Hubble Constant Measurement from Three Large-Separation Quasars Strongly Lensed by Galaxy Clusters
Kate Napier, Keren Sharon, Håkon Dahle +5
Tension between cosmic microwave background-based and distance ladder-based determinations of the Hubble constant motivates pursuit of independent methods that ar…
