摘要:

在大天文台全天LIRG巡天(GOALS)中,根据$Herschel$ $Space$ $Observatory$光电探测器阵列照相机和分光仪(PACS)以及光谱和光度成像接收器(SPIRE)仪器的观测,给出了201个发光和超亮红外星系[LIRG:log $(L_{\rm IR}/L_\odot) = 11.00 - 11.99$,ULIRGs:log $(L_{\rm IR}/L_\odot) = 12.00 - 12.99$ ]的远红外(FIR)图像和光度测定。图像图集显示了三个PACS波段(70、100和160 $μ$ m)和三个SPIRE波段(250、350和500 $μ$ m)中的每个GOALS靶点,优化以显示高和低表面亮度水平下的结构,图像缩放以简化$\sim$ $100\times100$ kpc $^2$相同物理区域中结构的比较。合并系统中的伴星系的通量密度在可能的情况下提供,取决于它们的角间距和每个通带的空间分辨率,以及积分系统通量(分量之和)。该数据集构成了GOALS Herschel OT1观测计划的成像和测光部分,并与哈勃太空望远镜的地图集互补(Evans等人,2017,准备中)。斯皮策太空望远镜(Mazzarella等人,2017年,准备中),和钱德拉X射线天文台(Iwasawa et al. 2011,2017,in prep.)。总的来说,这些数据将使广泛的详细研究活动星系核和星暴活动在最明亮的红外星系在当地的宇宙。

英文摘要:

Far-infrared (FIR) images and photometry are presented for 201 Luminous and Ultraluminous Infrared Galaxies [LIRGs: log$(L_{\rm IR}/L_\odot) = 11.00 - 11.99$, ULIRGs: log$(L_{\rm IR}/L_\odot) = 12.00 - 12.99$], in the Great Observatories All-Sky LIRG Survey (GOALS) based on observations with the $Herschel$ $Space$ $Observatory$ Photodetector Array Camera and Spectrometer (PACS) and the Spectral and Photometric Imaging Receiver (SPIRE) instruments. The image atlas displays each GOALS target in the three PACS bands (70, 100, and 160 $μ$m) and the three SPIRE bands (250, 350, and 500 $μ$m), optimized to reveal structures at both high and low surface brightness levels, with images scaled to simplify comparison of structures in the same physical areas of $\sim$$100\times100$ kpc$^2$. Flux densities of companion galaxies in merging systems are provided where possible, depending on their angular separation and the spatial resolution in each passband, along with integrated system fluxes (sum of components). This dataset constitutes the imaging and photometric component of the GOALS Herschel OT1 observing program, and is complementary to atlases presented for the Hubble Space Telescope (Evans et al. 2017, in prep.), Spitzer Space Telescope (Mazzarella et al. 2017, in prep.), and Chandra X-ray Observatory (Iwasawa et al. 2011, 2017, in prep.). Collectively these data will enable a wide range of detailed studies of AGN and starburst activity within the most luminous infrared galaxies in the local Universe.
