论文摘要
最近的JWST暂定发现超级（红移$ z> 10 $），相对较大（恒星质量$ m_* = 10^{8-9} m _ {\ odot} $）进化，并进化为（金属$ z \ z \ z \ of 0.1 z _ {\ odot} $ quilest $。光谱和非常小的灰尘衰减（$ a _ {\ rm v} \ leq 0.02 $）挑战了我们对这些系统的解释。为了解决拼图，我们提出了两种溶液，其中灰尘要么（a）被辐射压力喷出，要么（b）相对于紫外线发射区域隔离。我们阐明了两种情况应用的条件，并表明它们可以被ALMA观察结果歧视，例如最近在GHZ2（$ Z \ simeq 12 $）中对$88μm$ dust Continuum的未检测，有利于粉尘弹射。
The recent JWST tentative discovery of a population of super-early (redshift $z> 10$), relatively massive (stellar mass $M_* = 10^{8-9} M_{\odot}$) and evolved (metallicity $Z \approx 0.1 Z_{\odot}$) galaxies, which nevertheless show blue ($β\simeq -2.6$) spectra, and very small dust attenuation ($A_{\rm V} \leq 0.02$), challenges our interpretation of these systems. To solve the puzzle we propose two solutions in which dust is either (a) ejected by radiation pressure, or (b) segregated with respect to UV-emitting regions. We clarify the conditions for which the two scenarios apply, and show that they can be discriminated by ALMA observations, such as the recent non-detection of the $88μm$ dust continuum in GHZ2 ($z\simeq 12$) favouring dust ejection.
