WebWe study the topology of large-scale structure in the Center for Astrophysics Redshift Survey, which now includes ~12,000 galaxies with limiting magnitude m_B_ <= 15.5. The dense sampling and large volume of this survey allow us to compute the topology on smoothing scales from 6 to 20 h^-1^ Mpc; we thus examine the topology of structure in … WebJun 13, 2024 · The 2MASS Redshift Survey (2MRS) is an ambitious map of the galaxies relatively close to the Milky Way.

Using the supplied directions, students first color the key, then color-code the following features: Sun Galaxies 0-249 million light years Galaxies 250-499 million light years Galaxies 500-749 million light years Stick Man Great Wall Voids
WebThe Optical Redshift Survey (Santiago et al., 1995), had a depth of 80h-1 Mpc, similar to the first CfA survey, but attempted a complete coverage of the sky (except for the dusty avoidance zone around the galactic equator). They measured about 1300 new redshifts, including about 8500 redshifts in total.
WebThis data provides a map of galaxies in three dimensions, allowing astronomers to piece together how galaxies group on the largest scales in the universe.
