A detailed study of dwarf galaxies in the core of the Coma Cluster
Journal of astrophysics and astronomyIn an earlier paper, we determined the morphological types of galaxies in the Coma Cluster using data from the HST/ACS Coma Cluster treasury survey. Of the 132 members, 51 are non-dwarfs and 81 are dwarfs.

. Past millimeter-wave galaxy surveys have primarily probed the brightest starburst galaxies only and suffered heavily from confusion. The interpretation of existing surveys has also been hindered by the lack of reliable redshift indicators for measuring

Testing the Correlation Between Host Galaxy Mass and Redshift Using the Pantheon Survey Data
Engineering and Applied Sciences JournalThis study investigates the relationship between redshift and host galaxy mass using the Pantheon Supernova Survey dataset. The hypothesis that galaxies with identical luminous distances should have the same host mass is tested using statistical ...

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 ...

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.
