The fifth data release of the Kilo Degree Survey: Multi-epoch optical/NIR imaging covering wide and legacy-calibration fields
Angus H. Wright, Konrad Kuijken, Hendrik Hildebrandt +51
We present the final data release of the Kilo-Degree Survey (KiDS-DR5), a public European Southern Observatory (ESO) wide-field imaging survey optimised for weak gravitational lens…
Using Convolutional Neural Networks to Search for Strongly Lensed Quasars in KiDS DR5
Zizhao He, Rui Li, Yiping Shu +13
Gravitationally strongly lensed quasars (SL-QSO) offer invaluable insights into cosmological and astrophysical phenomena. With the data from ongoing and next-generation surveys, th…
Enhancing Photometric Redshift Catalogs Through Color-Space Analysis: Application to KiDS-Bright Galaxies
Priyanka Jalan, Maciej Bilicki, Wojciech A. Hellwing +11
We present a method to refine photometric redshift galaxy catalogs by comparing their color-space matching with overlapping spectroscopic calibration data. We focus on cases where…
Galaxy And Mass Assembly (GAMA): Data Release 4 and the z < 0.1 total and z < 0.08 morphological galaxy stellar mass functions
Simon P. Driver, Sabine Bellstedt, Aaron S. G. Robotham +67
In Galaxy And Mass Assembly Data Release 4 (GAMA DR4), we make available our full spectroscopic redshift sample. This includes 248682 galaxy spectra, and, in combination with earli…
Constraints on galaxy formation from the cosmic-far-infrared-background\,\,optical-imaging cross-correlation using \textit{Herschel} and UNIONS
Seunghwan Lim, Ryley Hill, Douglas Scott +11
Using {\it Herschel}-SPIRE imaging and the Canada-France Imaging Survey (CFIS) Low Surface Brightness data products from the Ultraviolet Near-Infrared Optical Northern Survey (UNIO…
High-quality strong lens candidates in the final Kilo Degree survey footprint
R. Li, N. R. Napolitano, C. Spiniello +16
We present 97 new high-quality strong lensing candidates found in the final , that completed the full area of the Kilo-Degree Survey (Ki…
The Weak Lensing Radial Acceleration Relation: Constraining Modified Gravity and Cold Dark Matter theories with KiDS-1000
Margot M. Brouwer, Kyle A. Oman, Edwin A. Valentijn +22
We present measurements of the radial gravitational acceleration around isolated galaxies, comparing the expected gravitational acceleration given the baryonic matter with the obse…
Halo shapes constrained from a pure sample of central galaxies in KiDS-1000
Christos Georgiou, Henk Hoekstra, Konrad Kuijken +12
We present measurements of , the ratio of the aligned components of the projected halo and galaxy ellipticities, for a sample of central galaxies using weak gravitational lens…
Bright galaxy sample in the Kilo-Degree Survey Data Release 4: selection, photometric redshifts, and physical properties
M. Bilicki, A. Dvornik, H. Hoekstra +16
We present a bright galaxy sample with accurate and precise photometric redshifts (photo-zs), selected using photometry from the Kilo-Degree Survey (KiDS) Da…
GAMA+KiDS: Empirical correlations between halo mass and other galaxy properties near the knee of the stellar-to-halo mass relation
Edward N. Taylor, Michelle E. Cluver, Alan Duffy +16
We use KiDS weak lensing data to measure variations in mean halo mass as a function of several key galaxy properties (namely: stellar colour, specific star formation rate, Sersic i…
The fourth data release of the Kilo-Degree Survey: ugri imaging and nine-band optical-IR photometry over 1000 square degrees
K. Kuijken, C. Heymans, A. Dvornik +20
The Kilo-Degree Survey (KiDS) is an ongoing optical wide-field imaging survey with the OmegaCAM camera at the VLT Survey Telescope, specifically designed for measuring weak gravita…

Dependence of GAMA galaxy halo masses on the cosmic web environment from 100 square degrees of KiDS weak lensing data
Margot M. Brouwer, Marcello Cacciato, Andrej Dvornik +31
Galaxies and their dark matter haloes are part of a complex network of mass structures, collectively called the cosmic web. Using the tidal tensor prescription these structures can…
