Amplitude constraints on dark energy
Scott Melville
This talk gives a short introduction to the ``UV/EFT correspondence", which uses scattering amplitudes to relate the Effective Field Theory (EFT) coefficients probed by low-energy…
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…
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…
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…
Distant foreground and the Hubble constant tension
Vladimir Yershov
It is possible to explain the discrepancy (tension) between the local measurement of the cosmological parameter (the Hubble constant) and its value derived from the Planck-mi…
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…
The Latest Constraints on Inflationary B-modes from the BICEP/Keck Telescopes
Keck Collaboration, P. A. R. Ade, Z. Ahmed +92
For the past decade, the BICEP/Keck collaboration has been operating a series of telescopes at the Amundsen-Scott South Pole Station measuring degree-scale -mode polarization im…
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…
An Estimator for Lensing Potential from Galaxy Number Counts
Viraj Nistane
We derive an estimator for the lensing potential from galaxy number counts which contains a linear and a quadratic term. We show that this estimator has a much larger signal-to-noi…
Testing the 10 spectrograph units for DESI: approach and results
S. Perruchot, P. -E. Blanc, J. Guy +34
The recently commissioned Dark Energy Spectroscopic Instrument (DESI) will measure the expansion history of the Universe using the Baryon Acoustic Oscillation technique. The spectr…
