Fundamental plane distances and peculiar velicities of 140 groups and clusters of galaxies at low redshifts: the Hubble diagram

Astronomičeskij žurnal
We used the fundamental plane (FP) of early-type galaxies (data from the Sloan Digital Sky Survey) to measure the relative distances and peculiar velocities of 140 groups and clusters of galaxies at low redshifts ( z0.12). We have constructed the Hubble diagram between the distances of galaxy groups/clusters and their radial velocities in the CMB ...

[A New Redshift Measuring Method for Low-Quality Galaxy Spectra Based on Multi Resolution Fusion Distance].

Guang pu xue yu guang pu fen xi = Guang pu, 2018
The redshift measurement of galaxy spectrum is a key issue in large astronomical spectral survey. Its goal is to extract the redshift from spectrum, which is caused the Doppler Effect. With the development of the extragalactic sky survey project, the distance (redshift) of the observed targets is becoming further.
