论文摘要
Luca（来自Calar Alto的本地宇宙）被认为是喀拉尔语中音天文台的新一代科学计划。它提出了在CAHA 3.5-m望远镜上建造一个具有六千个光纤纤维（IFU-6000）的大型整体场单元（IFU）光谱仪，以用前所未有的空间分辨率在3D中绘制我们的宇宙社区。将两个星系样品定义为绘制局部宇宙：（i）局部体积中的102个星系为11 MPC，（II）处女座簇中的218个星系。开发了一个补充项目，以绘制当地宇宙中的三个最大星系，即M31，M33和M101与Schmidt望远镜。在这份白皮书中，我们描述了Luca项目科学辩护和调查策略，以及IFU-6000仪器的技术描述，其性能和设计。
LUCA (Local Universe from Calar Alto) was conceived as a new generation science program for the Calar Alto Observatory. It proposed the construction of a large Integral Field Unit (IFU) spectrograph with six thousands optical fibers (IFU-6000) at the CAHA 3.5-m telescope to map our universe neighborhood in 3D with an unprecedented spatial resolution. Two galaxy samples were defined to map the local universe: (i) 102 galaxies in the Local Volume, out to 11 Mpc, and (ii) 218 galaxies in the Virgo cluster. A complementary project was developed to map the three largest galaxies in the local universe, M31, M33, and M101 with the Schmidt telescope. In this white paper we describe the LUCA Project science justification and survey strategy, as well as a technical description of the IFU-6000 instrument, its performance, and design.
