Cfa redshift survey
WebApr 20, 1999 · The Zwicky Catalog of galaxies (ZC), with m_Zw<=15.5mag, has been the basis for the Center for Astrophysics (CfA) redshift surveys. To date, analyses of the ZC and redshift surveys based on it have relied on heterogeneous sets of galaxy coordinates and redshifts. Here we correct some of the inadequacies of previous catalogs by … WebWe present redshifts for a sample of 4391 galaxies with magnitude m B (0) <=15.5 covering 20 h <=α<=4 h in right ascension and -2.5d<=δ<=90 deg in declination. This sample is complete for all galaxies in the merge of the Zwicky …

WebThe redshift survey in this region is 99.5% complete to the Zwicky catalogue limit, m Zw = 15.7. It is 99.9% complete to m Zw = 15.5, the CfA Redshift Survey (CfA2) magnitude limit. The survey region is adjacent to the northern portion of CfA2, overlaps the northernmost slice of the Las Campanas Redshift Survey, includes the southern WebCfA Redshift Survey.

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 …
In astronomy, a redshift survey is a survey of a section of the sky to measure the redshift of astronomical objects: usually galaxies, but sometimes other objects such as galaxy clusters or quasars. Using Hubble's law, the redshift can be used to estimate the distance of an object from Earth. By combining redshift with angular position data, a redshift survey maps the 3D distribution of matter with…
