我们展示了南方测光本地宇宙巡天（S-PLUS）的第五次数据发布（DR5），覆盖2491个区域的4592平方度。使用配备雅瓦拉姆布雷12滤镜系统的巴西机器人望远镜T80-South进行观测。数据产品包括FITS图像和包含超过1.13亿个探测的通量、星等和形状参数的广泛目录。还提供了几个增值目录。此次发布首次包括沿银盘110平方度的覆盖范围。对长蛇座和唧筒座星系团的初步分析得出基于光谱和高质量测光红移的1706个团簇成员的更新目录。我们的测光数据显示两个星系团具有相似比例的相对于其中心距离有Hα过剩的星系。样本中所有物体的空间分布突出了连接两个星系团的桥梁。我们验证S-PLUS DR5为未来从太阳系研究到宇宙学的科学调查提供了坚实基础。
英文摘要
We present the 5th data release (DR5) of the Southern Photometric Local Universe Survey (S-PLUS), covering 4592 square degrees across 2491 fields. Observations were conducted with the T80-South, a Brazilian robotic telescope equipped with the Javalambre 12-filter system, containing five broad- and seven narrowband filters. Data products feature FITS images and extensive catalogs containing fluxes, magnitudes, and shape parameters for over 113 million detections. In addition, several value-added catalogs are provided, offering photometric redshifts (photo-zs), object classifications, masks, and extinction coefficients. For the first time, this release includes coverage of 110 square degrees along the Galactic disk, facilitating new research into Galactic structure and stellar populations. The release also provides full coverage of the Hydra Supercluster and numerous other nearby clusters with improved data reduction and calibration, enhancing photo-z accuracy, which is vital for large-scale structure studies. A preliminary analysis of the Hydra and Antlia galaxy clusters up to $5 \times R_{200}$ yields an updated catalog of 1706 cluster members based on both spectroscopic and high-quality photo-zs. Our photometric data shows that both clusters have a similar proportion of galaxies with an H$α$ excess relative to their clustercentric distance, though Hydra has a higher fraction near its center. Additionally, the spatial distribution of all objects in our sample highlights a bridge connecting both clusters. We verify that S-PLUS DR5 provides a solid foundation for future scientific investigations, ranging from Solar System studies to Cosmology.
