Precise weak lensing constraints from deep high-resolution $K_{\mathrm{s}}$ images: VLT/HAWK-I analysis of the super-massive galaxy cluster RCS2$J$232727.7$-$020437 at $z=0.70$

We demonstrate that deep good-seeing VLT/HAWK-I $K_{\mathrm{s}}$ images complemented with $g$+$z$-band photometry can yield a sensitivity for weak lensing studies of massive galaxy c…
