Power Spectra of JWST images of Local Galaxies: Searching for Disk Thickness

Power Spectra of JWST images of Local Galaxies: Searching for Disk Thickness

JWST/MIRI images have been used to study the Fourier transform power spectra (PS) of two spiral galaxies, NGC 628 and NGC 5236, and two dwarfs, NGC 4449 and NGC 5068, at distances ranging from 4 to 10 Mpc. The PS slopes on scales larger than 200 pc range from $-0.6$ at $21\mu$m to $-1.2$ at $5.6\mu$...
