We study the properties of the Luminous Red Galaxies (LRGs) selected from the 4th data release of the Kilo Degree Survey (KiDS-1000) via galaxy-galaxy lensing of the background galaxies from KiDS-1000. We use a halo model formalism to interpret our measurements and obtain estimates of the halo masses and the satellite fractions of the LRGs, resulting in halo masses $2.7 \times 10^{12} h^{-1} {\rm M}_{\odot}Comment: 14 pages, 6 figures, submitted to A&A |
