PEARLS: NuSTAR and XMM-Newton Extragalactic Survey of the JWST North Ecliptic Pole Time Domain Field VI: Multiwavelength SED Analysis
Rafael Ortiz, Francesca Civano, Rogier A. Windhorst +27
We model spectral energy distributions of 261 X-ray sources to in the North Ecliptic Pole Time Domain Field, extending prior XMM-Newton and NuSTAR analyses. Using the st…
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…
Forecasting the Observable Rates of Gravitationally Lensed Supernovae for the PASSAGES Dusty Starbursts
Patrick S. Kamieneski, Rogier A. Windhorst, Brenda L. Frye +19
More than 60 years have passed since the first formal suggestion to use strongly-lensed supernovae to measure the expansion rate of the Universe through time-delay cosmography. Yet…
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…
Cryogenic optical beam steering for superconducting device calibration
K. Stifter, H. Magoon, A. J. Anderson +22
We have developed a calibration system based on a micro-electromechanical systems (MEMS) mirror that is capable of delivering an optical beam over a wavelength range of 180 -- 2000…
