The Great Observatories All-sky LIRG Survey (GOALS) combines data from NASA's Spitzer, Chandra, Hubble and GALEX observatories, together with ground-based data into a comprehensive imaging and spectroscopic survey of over 200 low redshift Luminous Infrared Galaxies (LIRGs). The LIRGs are a complete subset of the IRAS Revised Bright Galaxy Sample (RBGS). The LIRGs targeted in GOALS span the full range of nuclear spectral types defined via traditional optical line-ratio diagrams as well as interaction stages. They provide an unbiased picture of the processes responsible for enhanced infrared emission in galaxies in the local Universe. As an example of the analytic power of the multi-wavelength GOALS dataset, we present data for the interacting system VV 340 (IRAS F14547+2449). Between 80-95% of the total far-infrared emission (or about 5E11 solar luminosities) originates in VV 340 North. While the IRAC colors of VV 340 North and South are consistent with star-forming galaxies, both the Spitzer IRS and Chandra ACIS data indicate the presence of a buried AGN in VV 340 North. The GALEX far and near-UV fluxes imply a extremely large infrared "excess" (IRX) for the system (IR/FUV = 81) which is well above the correlation seen in starburst galaxies. Most of this excess is driven by VV 340 N, which alone has an IR excess of nearly 400. The VV 340 system seems to be comprised of two very different galaxies - an infrared luminous edge-on galaxy (VV 340 North) that dominates the long-wavelength emission from the system and which hosts a buried AGN, and a face-on starburst (VV 340 South) that dominates the short-wavelength emission.
Hubble Space Telescope ACS Imaging of the GOALS Sample: Quantitative Structural Properties of Nearby Luminous Infrared Galaxies with L_IR > 10^{11.4} L_sun
利用哈勃空间望远镜（\it Hubble Space Telescope，HST）/先进巡天照相机（Advanced Camera for Surveys，ACS）对大天文台全天红外星系巡天（GOALS）样本中的85个亮和超亮（$L_{\rm IR} > 10^{11.4}$ L $_\odot$）红外星系（LIRG和ULIRG）的结构特性进行了研究。对F814 W "{\it I}波段"图像进行了二维GALFIT分析，将每个星系适当地分解为凸起、盘、中央PSF和恒星棒分量。在LIRGs中观察到无隆起的盘系统的比例（35%）高于ULIRGs（20%），其中盘+隆起系统构成LIRGs（55%）和ULIRGs（45%）的主要部分。此外，核球+盘系统是最主要的后期合并星系类型，也是LIRG和ULIRGs在星系-星系核分离的几乎每个阶段的主要类型。GOALS星系的{\it I}带主星系的平均绝对星等为$-22.64\pm$ 0.62等（1.8 $^{+1.4}_{-0.4}$ L $^*_I$），而GOALS星系的平均隆起绝对星等比主星系的平均星等弱约1.1等。几乎所有的ULIRG都有在GOALS膨胀星等范围的高端（-20.6到-23.5等）的膨胀星等。在GOALS双星系统的质量比是一致的，与大多数的星系是主要合并的结果，和检查的残余主机强度比在GOALS双星系统表明，较小的同伴遭受更多的…
New AGN classifications in the Swift/BAT All-Sky Hard X-ray Survey
通过在San Pedro Martir（Mexico）望远镜上进行的光学活动，并使用6dF档案（http：//www.aao.gov.au/local/www/6df，Jones et al. 2004），我们确定或给出了Swift/BAT 22个月全天硬X射线巡天（Baumgartner et al. 2008，Tueller et al. 2010）中8个新发现的活动星系核（AGN）的更好分类。所有这些物体都有用Swift/XRT或Chandra或XMM存档数据进行的观测，这些数据使我们能够精确地确定它们的光学对应物，这要归功于这些天文台提供的精确（优于几个角秒）软X射线位置。这些信息使我们能够获得所有这些对应物的光谱，因为只有三个光谱是在线可用的，但没有通量校准，使我们能够揭示它们的真实性质（Baumgartner等人，2008年仅根据它们的X射线性质进行了初步分类）。在这里，我们提出的光谱，以及相应的发现图表获得的DSS-II红色调查，这8个源。我们发现我们的样品是由7个Seyfert 2和1个Seyfert 1组成的，红移在0.009和0.068之间。
