摘要:

我们提出的第一个数据发布的天炉座深度调查(FDS),使用宽视场成像仪OmegaCAM安装在VST在SDSS的u ',g',r ',和i'-波段覆盖天炉座星系团和下降的天炉座A组的成像调查。FDS是NOVA(以前称为FOCUS-PI:R)和F. Peletier)和INAF(作为VEGAS-PI的一部分:M。Capaccioli和E. Iodice)。在约28平方度的面积上暴露约9小时,该巡天数据集是研究天炉座星系团成员和正在下沉的天炉座A星系团的遗留数据集,其表面亮度极限为~28 mag/arcsec ^[2](1角秒^[2]面积上的1-sigma表面亮度)并开辟了一个新的参数制度,调查的作用,集群环境中塑造其星系人口的属性。在室女座星系团之后,天炉座是离我们第二近的星系团,由于其不同的质量和演化状态,它提供了一个有价值的比较,使人们有可能了解星系和星系团的各种演化影响。有关调查的详细信息,请参阅A。文霍拉河F. Peletier,E.劳里凯宁等人,2018,A & A 620,165。在此版本中,存在使用系统减少的181 Gb(压缩)文件。在即将发行的版本中,将提供包括矮星系、球状星团和背景星系在内的完整样本源目录。数据产品可通过ESO科学门户网站www.example.com获得2020 - 08 - 26

英文摘要:

We present the first data release of the Fornax Deep Survey (FDS), an imaging survey using using the wide-field imager OmegaCAM mounted on the VST in the SDSS u', g', r', and i'-bands covering the Fornax Galaxy Cluster and the infalling Fornax A Group. FDS is a joint project between NOVA (previously called FOCUS - PI: R. F. Peletier) and INAF (as part of VEGAS - PIs: M. Capaccioli and E. Iodice). With exposure times of about 9 hours over an area of ~28 square degrees, this survey is a legacy dataset for studies of members of the Fornax Galaxy Cluster and the infalling Fornax A Group down to a surface brightness limit of ~28 mag/arcsec^2 (1-sigma surface brightness over a 1 arcsecond^2 area) and opens a new parameter regime to investigate the role of the cluster environment in shaping the properties of its galaxy population. After the Virgo cluster,Fornax is the second nearest galaxy cluster to us, and with its different mass and evolutionary state, it provides a valuable comparison that makes it possible to understand the various evolutionary effects on galaxies and galaxy clusters. Details about the survey can be found in A. Venhola, R. F. Peletier, E. Laurikainen et al., 2018, A&A 620, 165. In this release, 181 Gb of (compressed) fits files reduced using the system are present. Catalogues with the complete sample of sources including dwarf galaxies part of the cluster, globular clusters, and background galaxies will be provided in forthcoming releases. The data products are available via the ESO Science Portal at https://archive.eso.org/scienceportal/home?publ_date=2020-08-26
