Early Telescope Throughput Results from the Collimated Beam Projector at the Vera C. Rubin Observatory
Nathan Amouroux, Parker Fagrelius, Thibault Guillemin +6
The Vera C. Rubin Observatory LSST requires precise photometric calibration to meet its science goals, particularly for cosmological analyses based on Type Ia supernovae. The Colli…
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…
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 +9
This article details the optimization and the characterization of the hologram described in a companion paper published in 2021, which showed the superiority of a holographic optic…
StarDICE III: Characterization of the photometric instrument with a Collimated Beam Projector
Thierry Souverin, Jérémy Neveu, Marc Betoule +18
The measurement of type Ia supernovae magnitudes provides cosmological distances, which can be used to constrain dark energy parameters. Large photometric surveys require a substan…
Design and performance of a Collimated Beam Projector for telescope transmission measurement using a broadband light source
K. Sommer, J. Cohen-Tanugi, B. Plez +9
Type Ia supernovae are the most direct cosmological probe to study dark energy in the recent Universe, for which the photometric calibration of astronomical instruments remains one…
Slitless spectrophotometry with forward modelling: principles and application to atmospheric transmission measurement
Jérémy Neveu, Vincent Brémaud, Pierre Antilogus +9
In the next decade, many optical surveys will aim to tackle the question of dark energy nature, measuring its equation of state parameter at the permil level. This requires trustin…
Measurement of telescope transmission using a Collimated Beam Projector
Thierry Souverin, Jérémy Neveu, Marc Betoule +17
The number of type Ia supernova observations will see a significant growth within the next decade, especially thanks to the Legacy Survey of Space and Time undertaken by the Vera R…
How in situ atmospheric transmission can affect cosmological constraints from type Ia supernovae ?
Jérémy Neveu, Vincent Brémaud, Sébastien Bongard +3
The measurement of type Ia supernova colours in photometric surveys is the key to access to cosmological distances. But for future large surveys like the Large Survey of Space and…
A transmission hologram for slitless spectrophotometry on a convergent telescope beam. 1. Focus and resolution
Marc Moniez, Jérémy Neveu, Sylvie Dagoret-Campagne +2
We report in this paper the test of a plane holographic optical element to be used as an aberration-corrected grating for a slitless spectrograph, inserted in a convergent telescop…
