Overview of the Instrumentation for the Dark Energy Spectroscopic Instrument [PDF]
Astronomical Journal, 2022 The Dark Energy Spectroscopic Instrument (DESI) embarked on an ambitious 5 yr survey in 2021 May to explore the nature of dark energy with spectroscopic measurements of 40 million galaxies and quasars. DESI will determine precise redshifts and employ the B. Abareshi, J. Aguilar, S. Ahlen, S. Alam, D. Alexander, R. Alfarsy, L. Allen, C. Prieto, O. Alves, J.Ameel, E. Armengaud, J. Asorey, A.

Proceedings of the National Academy of Sciences, 1986 The mean relation between distance and redshift for galaxies is reviewed as an observational question. The luminosity function for galaxies is an important ingredient and is given explicitly. We discuss various observational selection effects that are important for comparison of the linear and quadratic distance-redshift laws.

Monthly Notices of the Royal Astronomical Society, 2016 We analyse the largest spectroscopic samples of galaxy clusters to date, and provide observational constraints on the distance-redshift relation from baryon acoustic oscillations. The cluster samples considered in this work have been extracted from the Sloan Digital Sky Survey at three median redshifts, $z=0.2$, $z=0.3$, and $z=0.5$.VEROPALUMBO, ALFONSO, MARULLI, FEDERICO, MOSCARDINI, LAURO, MORESCO, MICHELE ENNIO MARIA, CIMATTI, ANDREA +4 moreopenaire +3 more sourcesRedshift-Distance Survey of Early-Type Galaxies: Dipole of the Velocity Field [PDF]
The Astrophysical Journal, 2000 We use the recently completed redshift-distance survey of nearby early-type galaxies (ENEAR) to measure the dipole component of the peculiar velocity field to a depth of cz ~ 6000 km/s. The sample consists of 1145 galaxies brighter than m_B=14.5 and cz < 7000 km/s, uniformly distributed over the whole sky, and 129 fainter cluster galaxies within the da Costa, L.

The current and next observation seasons will detect hundreds of gravitational waves (GWs) from compact binary systems coalescence at cosmological distances. When combined with independent electromagnetic measurements, the source redshift will be known,V. Alfradique, C. R. Bom, A. Palmese, G. Teixeira, L. Santana-Silva, A. Drlica-Wagner, A. Riley, C. E.
