The "dark dips" phenomenon in the LSST Camera on-sky images
Claire Juramy, Pierre Antilogus, Pierre Astier +4
When the commissioning camera (ComCam), and then the LSST Camera, started taking on-sky images at the Vera Rubin Observatory, some of the ITL STA3800 CCDs exhibited a previously un…
NSF-DOE Vera C. Rubin Observatory Observations of Interstellar Comet 3I/ATLAS (C/2025 N1)
Colin Orion Chandler, Pedro H. Bernardinelli, Mario JuriÄ +305
We report on the observation and measurement of astrometry, photometry, morphology, and activityof the interstellar object 3I/ATLAS, also designated C/2025 N1 (ATLAS) with the NSF-…
StarDICE IV: correcting visible photometry from atmospheric gray extinction using thermal infrared observations
Kélian Sommer, Bertrand Plez, Johann Cohen-Tanugi +11
Ground-based surveys such as the Vera C. Rubin Observatory's Legacy Survey of Space and Time require photometric calibration that is both long-term stable and spatially uniform at…
A transmission hologram for slitless spectrophotometry on a convergent telescope beam. Optimisation and characterization
Sylvie Dagoret-Campagne, Marc Moniez, Jeremy Neveu +8
This article details the optimisation and the characterisation of the hologram described in a companion paper published in 2021, which showed the superiority of a holographic optic…
The Spectroscopic Stage-5 Experiment
Robert Besuner, Arjun Dey, Alex Drlica-Wagner +106
The existence, properties, and dynamics of the dark sectors of our universe pose fundamental challenges to our current model of physics, and large-scale astronomical surveys may be…
How the StarDICE photometric calibration of standard stars can improve cosmological constraints?
T. Souverin, J. Neveu, M. Betoule +16
The number of type Ia supernova (SNe Ia) observations will grow significantly within the next decade, mainly thanks to the Legacy Survey of Space and Time (LSST) undertaken by the…
