论文摘要
我们介绍了ALMA镜头簇调查(ALCS)字段中的一组多波长镶嵌和光度目录。这些目录是通过从电荷汇编中重新处理档案数据来构建的,该汇编由$ \ textit {Hubble Space TeleScope} $($ \ textit {hst} $)在遗物,Clash和Hubble Frontier字段中构建。此外,我们通过利用所有可用的档案IRSA/SHA暴露,重建了$ \ textit {spitzer} $ irac 3.6和4.5 $ $ m $ m的马赛克。为了减轻在如此拥挤的区域中混合的效果,我们通过使用$ \ textit {spititer {spitzer} $ psf使用新颖的$ \ texttt {golfolfir} $软件来对$ \ textit {spitzer} $光度法建模。最终目录包含218,000个来源,涵盖了690 Arcmin $^2 $的组合面积。这些目录将作为协助未来Alma调查中搜索亚MM星系的重要工具,以及$ \ textit {hst} $ dark -irac sources的跟进。 Coupled with the available $\textit{HST}$ photometry the addition of the 3.6 and 4.5 $μ$m bands will allow us to place a better constraint on photometric redshifts and stellar masses of these objects, thus giving us an opportunity to identify high-redshift candidates for spectroscopic follow ups and answer the important questions regarding the epoch of reionization and formation of first galaxies.
We present a set of multi-wavelength mosaics and photometric catalogs in the ALMA lensing cluster survey (ALCS) fields. The catalogs were built by reprocessing of archival data from the CHArGE compilation, taken by the $\textit{Hubble Space Telescope}$ ($\textit{HST}$) in the RELICS, CLASH and Hubble Frontier Fields. Additionally we have reconstructed the $\textit{Spitzer}$ IRAC 3.6 and 4.5 $μ$m mosaics, by utilising all the available archival IRSA/SHA exposures. To alleviate the effect of blending in such a crowded region, we have modelled the $\textit{Spitzer}$ photometry by convolving the $\textit{HST}$ detection image with the $\textit{Spitzer}$ PSF using the novel $\texttt{golfir}$ software. The final catalogs contain 218,000 sources, covering a combined area of 690 arcmin$^2$. These catalogs will serve as an important tool in aiding the search of the sub-mm galaxies in future ALMA surveys, as well as follow ups of the $\textit{HST}$ dark - IRAC sources. Coupled with the available $\textit{HST}$ photometry the addition of the 3.6 and 4.5 $μ$m bands will allow us to place a better constraint on photometric redshifts and stellar masses of these objects, thus giving us an opportunity to identify high-redshift candidates for spectroscopic follow ups and answer the important questions regarding the epoch of reionization and formation of first galaxies.
