A quasar-anchored protocluster at z = 6.6 in the ASPIRE survey: II. an environmental analysis of galaxy properties in an overdense structure

We present in this paper (Paper II of the series) a 35 arcmin2 JWST/NIRCam imaging and wide-field slitless spectroscopy mosaic centered on J0305-3150, a luminous quasar at z = 6.61. The F356W grism data reveal 124 [O iii]+Hβ emitters at 5.3 < z < 7, 53 of which constitute a protocluster spanni...
