چکیده

We present a rest-frame optical morphological analysis of galaxies observed with the NIRCam imager on James Webb Space Telescope (JWST) as part GLASS-JWST Early Release Science program. select 388 sources at redshifts \(0.8 < z 5.4\) and use seven 0.9--5\micron\ filters to generate $gri$ composite color images, conduct visual classification. Compared HST-based work we find higher incidence disks bulges than expected $z>1.5$, revealed by rest frame imaging. detect 123 clear (58 $z>1.5$) which 76 have bulges. No evolution bulge fraction redshift is evident: 61\% \(z<2\) (\(N=110\)) versus 60\% \(z\geq2\) (\(N=13\)). A stellar mass dependence evident, visible in 80\% all disk \(> 10^{9.5}\, {\rm M}_{\odot}\) (\(N=41\)) but only 52\% \(M (\(N=82\)). supplement morphologies non-parametric measurements Gini Asymmetry coefficients $i$-band. Our are more asymmetric local galaxies, slightly values. When compared high-z ultraviolet Hubble Telescope, JWST shows regular types such disks, spiral arms smoother (i.e. lower Gini) symmetrical light distributions.

a frame semantic approach to the study of translating cultural scripts in salingers franny and zooey

the frame semantic theory is a nascent approach in the area of translation studies which goes beyond the linguistic barriers and helps us to incorporate cognitive and cultural factors to the study of translation. based on rojos analytical model (2002b), which centered in the frames or knowledge structures activated in the text, the present research explores the various translation problems that...

The Rest - Frame Fuv Morphologies of Star - Forming Galaxies at Z ∼ 1 . 5 and Z ∼ 4

We apply a new approach to quantifying galaxy morphology and identifying galaxy mergers to the rest-frame far-ultraviolet images of 82 z ∼ 4 Lyman break galaxies (LBGs) and 55 1.2 < z < 1.8 emission-line galaxies in the GOODS and Ultra Deep Fields. We compare the distributions of the Gini coefficient (G), second-order moment of the brightest 20% of galaxy light (M20), and concentration (C) for ...
