TL;DR
DEVILS is a large spectroscopic survey aiming to study galaxies at intermediate redshifts (0.3<z<1.0) with high completeness, using a strategic target selection and feedback approach to optimize observations.
Contribution
This paper introduces the design and target selection strategy of DEVILS, a new spectroscopic survey filling the gap between near and distant universe studies.
Findings
Survey successfully targeted ~60,000 galaxies.
Implemented a feedback strategy to optimize observing efficiency.
Initial spectroscopic observations conducted in late 2017-2018.
Abstract
The Deep Extragalactic VIsible Legacy Survey (DEVILS) is a large spectroscopic campaign at the Anglo-Australian Telescope (AAT) aimed at bridging the near and distant Universe by producing the highest completeness survey of galaxies and groups at intermediate redshifts (). Our sample consists of 60,000 galaxies to Y21.2mag, over 6deg in three well-studied deep extragalactic fields (Cosmic Origins Survey field, COSMOS, Extended Chandra Deep Field South, ECDFS and the X-ray Multi-Mirror Mission Large-Scale Structure region, XMM-LSS - all Large Synoptic Survey Telescope deep-drill fields). This paper presents the broad experimental design of DEVILS. Our target sample has been selected from deep Visible and Infrared Survey Telescope for Astronomy (VISTA) Y-band imaging (VISTA Deep Extragalactic Observations, VIDEO and UltraVISTA), with photometry measured by…
