LAE catalogue

Key Points

The aim is to catalogue Lyman alpha emitters detected in the high redshift universe from specific quasar fields.
Data collected from three quasar fields at redshift z~6.
Details include identifiers, sky coordinates, Lyman alpha emission, and systemic redshifts.
Flux and its error were calculated, along with the profiles' full-width-at-half-maximum.
A total of 156 Lyman alpha emitters were identified across the three quasar fields examined.
Astrometric corrections were applied based on GAIA literature positions.
Emission profiles were categorized based on single or doublet line profiles.

Abstract

The catalogue of the 156 Lyman alpha emitters detcted from the three quasar fields at z~6. Each column from left to right shows QSO: the respective quasar field from which they are detcted, ID: identifers assigned to them, RA and Dec: sky coordinates in degrees (corrected for astrometry based on GAIA corrected literature positions for the quasars) zLya: Lyman alpha emission redshift zₛys: systemic redshift using correlations from Verhamme et al. (2018) FWHM: full-width-at-half-maximum of each line profile in Angstroms Flux*1e-20: Flux of each LAE in ergs/s/cm² Fluxₑrr*1e-20: 1 sigma error in flux in units of ergs/s/cm² DOUBLET: a flag to indicate if the source has a single or doublet line profile Notes: Indicates if the source has already been discovered in the literature
