Development of a Retrieval-Augmented Generation Virtual Assistant for Enhanced Information Discovery at Rubin Observatory
Leanne P. Guy, Connor Yablonski, Aaron M. Meisner +5
The NSF-DOE Vera C. Rubin Observatory will generate petabytes of data through the Legacy Survey of Space and Time (LSST) over the next decade, enabling discoveries across a broad r…
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…
An overview of stray light findings and interpretation during on-sky commissioning of LSSTCam
Gabriele Rodeghiero, Alex Drlica-Wagner, Alessio Taranto +78
Wide-field telescopes are intrinsically difficult to shield from unwanted stray and scattered light, while the search to identify sources of contaminating light is frequently a cha…
Modeling of the diffuse background produced by the Vera C. Rubin Observatory M2 baffle scattered light
Alessio Taranto, Gabriele Rodeghiero, Luca Rosignoli +58
The Vera C. Rubin Observatory, with its unprecedented field of view and fast focal ratio, will survey the entire sky every 3.5 nights. This unique capacity requires dealing with of…
PSF-like Alpha-Particle Events in LSST Images
Guillem Megias Homar, Craig S. Lage, Pierre-François Léget +6
Rare -particle-induced charge clusters appear in LSST images as compact, PSF-like sources with a median FWHM of and median ellipticity consistent with…
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…
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…
Directly Characterizing Dome Seeing: Differential Image Motion Sensor Using Multisources (DIMSUM)
Ali Kurmus, Elana Urbach, Christopher W. Stubbs
Image degradation impedes our ability to extract information from astronomical observations. One factor contributing to this degradation is ``dome seeing", the reduction in image q…
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…
Precision Astronomy with Imperfect Fully Depleted CCDs -- An Introduction and a Suggested Lexicon
Christopher W. Stubbs
This paper summarizes the introductory presentation for a workshop that explored the challenges of making precision astronomical measurements using deeply depleted (thick) CCDs. Wh…
