Measuring the Universe with Galaxy Redshift Surveys [PDF]

, 2018
Galaxy redshift surveys are one of the pillars of the current standard cosmological model and remain a key tool in the experimental effort to understand the origin of cosmic acceleration. To this end, the next generation of surveys aim at achieving sub-percent precision in the measurement of the equation of state of dark energy $w(z)$ and the growth ...

Redshift distribution of gamma-ray bursts and star formation rate [PDF]

, 2006
Aims. The redshift distribution of gamma-ray bursts collected in the BATSE Catalog is compared with the star formation rate.We aim to clarify the accordance between them. We also study the case of comoving number density of bursts monotonously increasing

Correcting for Interloper Contamination in the Power Spectrum with Neural Networks

The Astrophysical Journal
Modern slitless spectroscopic surveys such as Euclid and Roman collect vast numbers of galaxy spectra, but their low signal-to-noise ratios often lead to incorrect redshift assignments when relying on a single emission line.

Clustering and redshift-space distortions in QSO and galaxy surveys [PDF]

, 2006
In this thesis, we exploit the potential of existing QSO and galaxy surveys for investigating the nature of the large scale structure in the Universe. A detailed analysis of clustering and redshift- space distortions allows us to constrain cosmological ...

Galaxy clustering and dynamics from redshift surveys [PDF]

, 1990
The clustering and dynamical properties of the 368 galaxies in the redshift surveys of Metcalfe et al. (1989) and Parker et al. (1986) are investigated. These galaxies were selected from ten high galactic latitude fields complete to a magnitude limit of ...

Validation of the Scientific Program for the Dark Energy Spectroscopic Instrument

The Astronomical Journal
The Dark Energy Spectroscopic Instrument (DESI) was designed to conduct a survey covering 14,000 deg ^2 over 5 yr to constrain the cosmic expansion history through precise measurements of baryon acoustic oscillations (BAO).
