Angular clustering and bias of photometric quasars in the Kilo-Degree Survey Data Release 4

Anjitha John William, Maciej Bilicki, Wojciech A. Hellwing +2

We investigate the angular clustering and effective bias of photometrically selected quasars in the Kilo-Degree Survey Data Release 4 (KiDS DR4). We update the previous photometric…

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…

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…

Hybrid-z: Enhancing Kilo-Degree Survey bright galaxy sample photometric redshifts with deep learning

Anjitha John William, Priyanka Jalan, Maciej Bilicki +3

We employ deep learning (DL) to improve photometric redshifts (photo-s) in the Kilo-Degree Survey Data Release 4 Bright galaxy sample (KiDS-Bright DR4). This dataset, used as a…
