TL;DR
This paper presents a comprehensive catalog of over 5,400 galaxies in the Perseus cluster, including morphological classifications and properties, based on deep imaging data, revealing trends in galaxy nucleation and contamination estimates.
Contribution
The study provides the largest and deepest morphological catalog of Perseus cluster galaxies, with detailed classifications and analysis of low-mass galaxy candidates and their properties.
Findings
Identified 496 early-type low-mass galaxy candidates.
Found a trend of increasing nucleation fraction with luminosity.
Catalog reaches 50% completeness at -12 mag in V-band.
Abstract
We present a catalog of 5437 morphologically classified sources in the direction of the Perseus galaxy cluster core, among them 496 early-type low-mass galaxy candidates. The catalog is primarily based on V-band imaging data acquired with the William Herschel Telescope, which we used to conduct automated source detection and to derive photometry. We additionally reduced archival Subaru multiband imaging data in order to measure aperture colors and to perform a morphological classification, benefiting from 0.5 arcsec seeing conditions in the r-band data. Based on morphological and color properties, we extracted a sample of early-type low-mass galaxy candidates with absolute V-band magnitudes in the range of -10 to -20 mag. In the color-magnitude diagram the galaxies are located where the red sequence for early-type cluster galaxies is expected, and they lie on the literature relation…
