Diagnosing the Effects of Spectroscopic Training Set Imperfection on Photometric Redshift Performance

Alice Crafford, Alex I. Malz, Tianqing Zhang +11

Most LSST extragalactic science will rely on photometric redshifts (photo-) to extract distance information for the galaxies. However, an incomplete or non-representative traini…

KiDS-Legacy: Consistency of cosmic shear measurements and joint cosmological constraints with external probes

Benjamin Stölzner, Angus H. Wright, Marika Asgari +33

We present a cosmic shear consistency analysis of the final data release from the Kilo-Degree Survey (KiDS-Legacy). By adopting three tiers of consistency metrics, we compare cosmo…

KiDS-Legacy: Redshift distributions and their calibration

Angus H. Wright, Hendrik Hildebrandt, Jan Luca van den Busch +30

We present the redshift calibration methodology and bias estimates for the cosmic shear analysis of the fifth and final data release (DR5) of the Kilo-Degree Survey (KiDS). KiDS-DR…

Quantifying the Detectability of Milky Way Satellites with Image Simulations: a Case Study with KiDS

Shiyang Zhang, Hendrik Hildebrandt, Ziang Yan +6

Ultra-faint dwarf galaxies, which can be detected as resolved satellite systems of the Milky Way, are critical to understanding galaxy formation, evolution, and the nature of dark…
