On The Very Bright Dropouts Selected Using the James Webb Space Telescope NIRCam Instrument
Bangzheng Sun, Haojing Yan
The selection of candidate high-redshift galaxies using the dropout technique targeting the Lyman-break signature sometimes yields very bright objects that are too luminous to be e…
