The Power of DESI for Photometric Redshift Calibration: A Case Study with KiDS-1000

Diana Blanco, Alexie Leauthaud, Johannes Ulf Lange +64

Accurate redshift estimates are a critical requirement for weak lensing surveys and one of the main uncertainties in constraints on dark energy and large-scale cosmic structure. In…

Clustering redshift distribution calibration of weak lensing surveys using the DESI-DR1 spectroscopic dataset

R. Ruggeri, C. Blake, J. Aguilar +63

We estimate the source redshift distribution of current weak lensing surveys by applying the clustering-based redshift calibration technique, using the galaxy redshift sample provi…

A Unified Photometric Redshift Calibration for Weak Lensing Surveys using the Dark Energy Spectroscopic Instrument

Johannes U. Lange, Diana Blanco, Alexie Leauthaud +61

The effective redshift distribution of galaxies is a critical component in the study of weak gravitational lensing. Here, we introduce a new method for determining fo…

Validation of the DESI-DR1 3x2-pt analysis: scale cut and shear ratio tests

N. Emas, A. Porredon, C. Blake +54

Combined survey analyses of galaxy clustering and weak gravitational lensing (3x2-pt studies) will allow new and accurate tests of the standard cosmological model. However, careful…

Can dynamic dark energy explain the tension, the `lensing is low' effect, or strong baryon feedback?

S. Heydenreich, A. Leauthaud, J. DeRose

We investigate the impact of a DESI motivated dynamic dark energy cosmology on three cosmological anomalies, the tension, the `lensing is low' effect, and observations of str…

Testing gravitational physics by combining DESI DR1 and weak lensing datasets using the E_G estimator

S. J. Rauhut, C. Blake, U. Andrade +61

The action of gravitational physics across space-time creates observable signatures in the behaviour of light and matter. We perform combined-probe studies using data from the Bary…

Relationship between 2D and 3D Galaxy Stellar Mass and Correlations with Halo Mass

Conghao Zhou, Alexie Leauthaud, Shuo Xu +8

Recent studies suggest that the stars in the outer regions of massive galaxies trace halo mass better than the inner regions and that an annular stellar mass provides a low scatter…
