Survey of galaxies within prominent nearby voids

We study the optical properties of a large sample of galaxies in low-density regions of the nearby universe. We make a 5 h^-1^ Mpc smoothed map of the galaxy density throughout...我们针对近邻宇宙低密度区域内的大样本星系的光学性质展开研究。我们构建了覆盖全域的、平滑尺度为5 h⁻¹百万秒差距（Mpc）的星系密度平滑分布图。
