Extended Data Fig. 1: Probability distribution function of host galaxy magnitude.
From: An interference-based method for the detection of strongly lensed gravitational waves
This figure presents the host galaxy apparent magnitude distribution for the three quadruple-image SLGWs identified in Main Fig. 3. The red histogram is the apparent magnitude distribution for CSST r band, and the blue histogram is the one for JWST F200W band. The difference between the red and blue only results from the filters and SED, nothing to do with the telescope aperture and exposure time. The grey shaded region stands for the magnitude greater than 26 where the host galaxy cannot be observed by using the CSST main survey.
