Halo spin and orientation in Interacting Dark Matter Dark Energy Cosmology
Guandi Zhao, Jiajun Zhang, Peng Wang +1
In recent years, the interaction between dark matter (DM) and dark energy (DE) has become a topic of interest in cosmology. Interacting dark matter-dark energy (IDE) models have a…
CURLING -- II. Improvement on the Inference from Pixelized Cluster Strong Lens Modeling
Yushan Xie, Huanyuan Shan, Yiping Shu +9
Strongly lensed supernovae (glSNe) provide a powerful, independent method to measure the Hubble constant, , through time delays between their multiple images. The accuracy o…
A Comparative Study of Halo Mass Estimates from Group Catalogs and Lensing Signals
Xinyue Chen, Weiwei Xu, Ran Li +3
We compare halo mass estimates from three galaxy group catalogs (redMaPPer, Yang21, and Zou21) with those derived from gravitational lensing measurements. Each catalog employs dist…
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…
KiDS-1000: Weak lensing and intrinsic alignment around luminous red galaxies
Maria Cristina Fortuna, Andrej Dvornik, Henk Hoekstra +8
We study the properties of luminous red galaxies (LRGs) selected from the fourth data release of the Kilo Degree Survey (KiDS-1000) via galaxy-galaxy lensing of the background gala…
