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…
Towards millimagnitude Photometry at the Vera Rubin Observatory: Aerosol Monitoring with Quadband Dispersed Imaging
Eske M. Pedersen, Christopher W. Stubbs, Merlin Fisher-Levine +3
As the frontier of precision astronomical photometry continues to advance, correcting for time-variable atmospheric transmission becomes increasingly important. We describe an obse…
Measuring Local Turbulence Along the Optical Path: Multi-beam Optical Seeing Sensor (MOSS)
Meghan A. Marangola, Elana K. Urbach, Christopher W. Stubbs
Deflection of light along the optical path is a major source of image degradation for ground-based telescopes. Methods have been developed to measure upper atmospheric seeing based…
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…
