TL;DR
The VIDEO survey provides deep near-infrared data over 12 square degrees, enabling studies of galaxy evolution, AGN activity, and large-scale structures up to redshift 4, with improved photometric redshifts and reduced outliers.
Contribution
This paper presents the first data release of the VIDEO survey, a deep near-infrared survey designed to study galaxy evolution and large structures from present day to high redshift.
Findings
Achieved 5-sigma depths of Z=25.7, Y=24.5, J=24.4, H=24.1, K_s=23.8 in 2 arcsec apertures.
Good astrometric agreement with 2MASS and source counts consistent with UltraVISTA.
Adding VIDEO data improves photometric redshift accuracy and reduces catastrophic outliers from 5.8% to 3.1%.
Abstract
In this paper we describe the first data release of the the Visible and Infrared Survey Telescope for Astronomy (VISTA) Deep Extragalactic Observations (VIDEO) survey. VIDEO is a ~12degree^2 survey in the near-infrared Z,Y,J,H and K_s bands, specifically designed to enable the evolution of galaxies and large structures to be traced as a function of both epoch and environment from the present day out to z=4, and active galactic nuclei (AGN) and the most massive galaxies up to and into the epoch of reionization. With its depth and area, VIDEO will be able to fully explore the period in the Universe where AGN and starburst activity were at their peak and the first galaxy clusters were beginning to virialize. VIDEO therefore offers a unique data set with which to investigate the interplay between AGN, starbursts and environment, and the role of feedback at a time when it was potentially…
