CANUCS: An Updated Mass and Magnification Model of A370 with JWST

The Astrophysical Journal
We present an updated mass and magnification model of galaxy cluster A370 using new NIRCam, NIRISS, and NIRSpec data from the Canadian NIRISS Unbiased Cluster Survey (CANUCS).

Accurate Measurement of the Lensing Magnification by BOSS CMASS Galaxies and Its Implications for Cosmology and Dark Matter

The Astrophysical Journal
Magnification serves as an independent and complementary gravitational lensing measurement to shear. We develop a novel method to achieve an accurate and robust magnification measurement around BOSS CMASS galaxies across physical scales of 0.016 h ^−1 ...

Cosmological Constraints from Combining Photometric Galaxy Surveys and Gravitational Wave Observatories

The Open Journal of Astrophysics
Spatial variations in survey properties due to selection effects generate substantial systematic errors in large-scale structure measurements in optical galaxy surveys on very large scales.
