TL;DR
The EFIGI catalogue provides a detailed, multiwavelength morphological database of 4458 nearby galaxies, enabling advanced studies of galaxy structure, classification, and environment with high completeness and reliability.
Contribution
It introduces a comprehensive, well-calibrated galaxy catalogue with detailed morphological attributes and multi-band imaging, aligned with the Hubble sequence and covering diverse galaxy types.
Findings
High morphological classification accuracy matching RC3 standards
Over 80% completeness for galaxies with 10<g<14
More than 99.5% of galaxies have known redshifts
Abstract
Now that large databases of resolved galaxy images are provided by modern imaging surveys, advanced morphological studies can be envisioned, urging for well defined calibration samples. We present the EFIGI catalogue, a multiwavelength database specifically designed for a dense sampling of all Hubble types. The catalogue merges data from standard surveys and catalogues (Principal Galaxy Catalogue, Sloan Digital Sky Survey, Value-Added Galaxy Catalogue, HyperLeda, and the NASA Extragalactic Database) and provides detailed morphological information. Imaging data are obtained from the SDSS DR4 in the u, g, r, i, and z bands for a sample of 4458 PGC galaxies, whereas photometric and spectroscopic data are obtained from the SDSS DR5 catalogue. Point-Spread Function models are derived in all five bands. Composite colour images of all objects are visually examined by a group of astronomers,…
