We analyze the Near Infrared ($\sim0.8-1μ$m) rest-frame morphologies of galaxies with $\log M_*/M_\odot>9$ in the redshift range $0<z<6$, compare with previous HST-based results and release the first JWST-based morphological catalog of $\sim20,000$ galaxies in the CEERS survey. Galaxies are classified into four main broad classes -- spheroid, disk+spheroid, disk, and disturbed -- based on imaging with four filters -- $F150W$, $F200W$, $F356W$, and $F444W$ -- using Convolutional Neural Networks trained on HST/WFC3 labeled images and domain-adapted to JWST/NIRCam. We find that $\sim90\%$ and $\sim75\%$ of galaxies at $z<3$ have the same early/late and regular/irregular classification, respectively, in JWST and HST imaging when considering similar wavelengths. For small (large) and faint objects, JWST-based classifications tend to systematically present less bulge-dominated systems (peculiar galaxies) than HST-based ones, but the impact on the reported evolution of morphological fractions is less than $\sim10\%$. Using JWST-based morphologies at the same rest-frame wavelength ($\sim0.8-1μ$m), we confirm an increase in peculiar galaxies and a decrease in bulge-dominated galaxies with redshift, as reported in previous HST-based works, suggesting that the stellar mass distribution, in addition to light distribution, is more disturbed in the early universe. However, we find that undisturbed disk-like systems already dominate the high-mass end of the late-type galaxy population ($\log M_*/M_\odot>10.5$) at $z\sim5$, and bulge-dominated galaxies also exist at these early epochs, confirming a rich and evolved morphological diversity of galaxies $\sim1$ Gyr after the Big Bang. Finally, we find that the morphology-quenching relation is already in place for massive galaxies at $z>3$, with massive quiescent galaxies ($\log M_*/M_\odot>10.5$) being predominantly bulge-dominated.

First results from the JWST Early Release Science Program Q3D: Turbulent times in the life of a $z \sim 3$ extremely red quasar revealed by NIRSpec IFU
极红类星体,其热光度超过$10^{47}$ erg s $^{-1}$,是一个迷人的高红移群体,在本地宇宙中不存在。它们是超大质量黑洞以爱丁顿极限或以上的速率吸积的最佳候选者,并且它们与迄今为止已知的最快速和最强大的电离气体流出有关。它们也是大质量星系的宿主。在这里,我们提出了第一个积分场单位(IFU)的观测高红移类星体的近红外光谱仪(NIRSpec)上的詹姆斯韦伯太空望远镜(JWST),目标SDSSJ 165202.64 +172852.3,一个非常红的类星体在$z=2.94$。JWST观测揭示了扩展的电离气体-如[OIII] $λ$ 5007所追踪的-在类星体的宿主星系,其流出物和环星系介质中。复杂的形态学和运动学意味着类星体居住在一个非常密集的环境中,在10-15 kpc的投影距离内有几个相互作用的同伴星系。环境的高密度和伴随星系的大速度表明,这个系统可能代表了一个正在形成的星系团的核心。该系统是两个或多个暗物质晕合并的良好候选者,每个暗物质晕的质量为几个$10^{13}$ M $_\odot$,并可能追踪到$z\sim3$处的一个暗物质结。
