A Radially Broad Collisional Cascade in the Debris Disk of γ Ophiuchi Observed by JWST

The A1V star γ  Oph, at a distance of 29.7 pc, is known from Spitzer imaging to host a debris disk with a large radial extent and from its spectral energy distribution to host inner warm dust. We imaged γ  Oph with the James Webb Space Telescope (JWST)/Mid-InfraRed Instrument at 15 and 25.5 μ m, rev...
