DECOMPOSITION OF DISTANT GALAXIES WITH SPIRAL ARMS
Аннотация и ключевые слова
Аннотация (русский):
We perform the photometric decomposition, including spiral arms, of 159 galaxies at $0.1 \leq z \leq 3.3$ imaged by HST and JWST in optical and near-infrared in rest-frame. We measure various properties of spiral structure and, in particular, we confirm that pitch angles increase and azimuthal length decrease with increasing $z$, implying that spiral structure becomes more wound with time. We also measure band-shifting effects, or the spiral-to-total ratio and width relative to the disc exponential scale, and find that band-shifting effects can be as significant, or even stronger than, evolutionary effects. Furthermore, the spiral structure becomes more asymmetric at higher redshifts.
