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…

Photometric Redshift Estimation for Rubin Observatory Data Preview 1 with Redshift Assessment Infrastructure Layers (RAIL)

T. Zhang, E. Charles, J. F. Crenshaw +87

We present the first systematic analysis of photometric redshifts (photo-z) estimated from the Rubin Observatory Data Preview 1 (DP1) data taken with the Legacy Survey of Space and…

Observational strategies for ultrahigh-energy neutrinos: the importance of deep sensitivity for detection and astronomy

Kumiko Kotera, Mainak Mukhopadhyay, Rafael Alves Batista +5

Detecting ultrahigh-energy neutrinos can take two complementary approaches with different trade-offs. 1)~Wide and shallow: aim for the largest effective volume, and to be cost-effe…

Bayesian Component Separation for DESI LAE Automated Spectroscopic Redshifts and Photometric Targeting

Ana Sofía M. Uzsoy, Andrew K. Saydjari, Arjun Dey +37

Lyman Alpha Emitters (LAEs) are valuable high-redshift cosmological probes traditionally identified using specialized narrow-band photometric surveys. In ground-based spectroscopy,…
