The detection of spiral arm modulation in the mass distribution of an optically flocculent galaxy
Ivanio Puerari, David L. Block, Bruce G. Elmegreen +2
Spiral arm modulation in NGC 4062 (an optical flocculent) is detected for the first time; the Fourier spectra of NGC 4062 and NGC 5248 (a classic grand design in optical images) ar…

The detection of spiral arm modulation in the stellar disk of an optically flocculent and an optically grand design galaxy
Ivanio Puerari, David L. Block, Bruce G. Elmegreen +2
Two dimensional Fourier spectra of near-infrared images of galaxies provide a powerful diagnostic tool for the detection of spiral arm modulation in stellar disks. Spiral arm modul…
