论文摘要
Planck All-Sky调查以分析重力透明的极端星爆（通道）项目旨在使用Planck All-Sky调查来识别一系列极具发光的星系，并探索其气体加油，引起的Starburst的性质，以及由此塑造其进化的结果反馈。在这里，我们报告了22个高红移发光的尘土飞机形成星系（DSFG）的标识，$ z = 1.1-3.3 $从使用紧凑型源（PCCS）和Wise All-Sky调查的Planck目录构建的候选列表中得出。通过使用AZTEC和大型毫米望远镜Alfonso Serrano（LMT）上的Redshift搜索接收器（RSR），通过随访尘埃连续成像和CO光谱证实了它们。它们的明显红外发光度跨越$（0.1-3.1）\ times 10^{14} l_ \ odot $（中位数为$ 1.2 \ times10^{14} l_ \ odot $），使其成为到目前为止发现的最明亮的星系。它们也是天空中最稀有的对象，源密度为$ \ lyssim0.01 $ deg $^{ - 2} $。我们的Atacama大毫米/亚毫米阵列（ALMA）1.1毫米连续观测，$θ$ $ \ $ $ \ $ 0.4”的分辨率显示出明确的环或弧形形态的特征，其特征的特征是强烈的镜头。$ l _ {\ rm ir} \ rm ir} \ gtrsim $ l_ （$ sfr \ gtrsim10^3 m_ \ odot $ yr $^{ - 1} $）表明它们是在这些红移中发现的最本质上发光的dsfg的放大版本，尽管它们的光谱能量分布（SED）分析很少可检测到的Agn活性。
The Planck All-Sky Survey to Analyze Gravitationally-lensed Extreme Starbursts (PASSAGES) project aims to identify a population of extremely luminous galaxies using the Planck All-Sky Survey and to explore the nature of their gas fuelling, induced starburst, and the resulting feedback that shape their evolution. Here, we report the identification of 22 high redshift luminous dusty star forming galaxies (DSFGs) at $z=1.1-3.3$ drawn from a candidate list constructed using the Planck Catalog of Compact Sources (PCCS) and WISE All-Sky Survey. They are confirmed through follow-up dust continuum imaging and CO spectroscopy using AzTEC and the Redshift Search Receiver (RSR) on the Large Millimeter Telescope Alfonso Serrano (LMT). Their apparent IR luminosities span $(0.1-3.1)\times 10^{14} L_\odot$ (median of $1.2\times10^{14}L_\odot$), making them some of the most luminous galaxies found so far. They are also some of the rarest objects in the sky with a source density of $\lesssim0.01$ deg$^{-2}$. Our Atacama Large Millimeter/submillimeter Array (ALMA) 1.1 mm continuum observations with $θ$ $\approx$ 0.4" resolution show clear ring or arc morphologies characteristic of strong lensing. Their lensing-corrected luminosity of $L_{\rm IR}\gtrsim 10^{13}L_\odot$ ($SFR\gtrsim10^3 M_\odot$ yr$^{-1}$) indicates that they are the magnified versions of the most intrinsically luminous DSFGs found at these redshifts. Our spectral energy distribution (SED) analysis finds little detectable AGN activity despite their enormous luminosity, and any AGN activity present must be extremely heavily obscured.
