Left: galaxy density maps (16 × 16 arcmin) centred on the HSC shear-selected cluster positions without an eFEDS match. Overlaid in red are X-ray contours, which were obtained by smoothing the raw X-ray image in the 0.5–2.0 keV energy band with a Gaussian of 24 arcsec. The black circles in the lower-left corners show the smoothing scale, FWHM = 200 kpc. Right: HSC-SSP optical images centred on the HSC shear-selected cluster positions. The 8 x 8 arcmin optical images of the central region are created using the z, i, and r bands. X-ray contours are shown in red, galaxy density contours in white (they are the same contours as the black ones in the corresponding galaxy density maps), and weak-lensing mass contours in yellow.
