The MOST Hosts Survey: Spectroscopic Observation of the Host Galaxies of ∼40,000 Transients Using DESI

The Astrophysical Journal Supplement Series
We present the Multi-Object Spectroscopy of Transient (MOST) Hosts survey. The survey is planned to run throughout the 5 yr of operation of the Dark Energy Spectroscopic Instrument (DESI) and will generate a spectroscopic catalog of the hosts of most ...

Constraining dark energy using real and mock galaxy surveys [PDF]

, 2009
In this thesis, we study how dark energy may be constrained by measurements of large-scale clustering in future galaxy surveys, and through the imprint of a time-varying large-scale potential on the CMB (the integrated Sachs-Wolfe effect).

First results from high redshift quasar searches in VIKING [PDF]

, 2012
This thesis presents the discovery of the first luminous z & 6.5 quasars in the VISTA kilo-degree Infrared Galaxy Survey (VIKING). After some basic quality control, quasar selection is investigated via use of initial data supplementedwith ...

Euclid: Quick Data Release (Q1) – Watching ICM-selected galaxy clusters with Euclid eyes: Prospects of Euclid data in the context of large SZE- and X-ray-based surveys★

Astronomy & Astrophysics
Galaxy clusters detected through their X-ray emission or Sunyaev–Zeldovich effect (SZE), both produced by the intracluster medium (ICM), have been successfully used in cosmological and astrophysical studies.

Using galaxy redshift surveys to detect gravitationally lensed quasars [PDF]

, 2000
Gravitationally lensed quasars can be discovered as a by-product of galaxy redshift surveys. Lenses discovered spectroscopically in this way should require less observational effort per event than those found in dedicated lens surveys.

Spectroscopic Confirmation of a Massive Protocluster with Two Substructures at z ≃ 3.1

The Astrophysical Journal
We present the results of a Keck and Northern Extended Millimeter Array spectroscopic survey of 507 galaxies, where we confirm the presence of two massive overdensities at z = 3.090−3.110 and z = 3.133−3.155 in the neighborhood of the GOODS-N, each with ...

Lensing convergence and the neutrino mass scale in galaxy redshift surveys [PDF]

, 2016
We demonstrate the importance of including the lensing contribution in galaxy clustering analyses with large galaxy redshift surveys. It is well known that radial cross-correlations between different redshift bins of galaxy surveys are dominated by ...
