TL;DR
This paper reports the discovery of five low-surface brightness dwarf galaxy candidates in Hickson Compact Group 90, marking the first such detections in a compact galaxy group, and analyzes their properties and potential interactions.
Contribution
First identification of LSB dwarf galaxy candidates in a compact galaxy group, expanding understanding of dwarf galaxy populations in dense environments.
Findings
Detected five LSB dwarf galaxy candidates in HCG 90.
Found a potential dwarf galaxy pair with 2 kpc separation.
Identified a nucleated dwarf with a possible nuclear stellar disc.
Abstract
We report the discovery of a very diverse set of five low-surface brightness (LSB) dwarf galaxy candidates in Hickson Compact Group 90 (HCG 90) detected in deep U- and I-band images obtained with VLT/VIMOS. These are the first LSB dwarf galaxy candidates found in a compact group of galaxies. We measure spheroid half-light radii in the range with luminosities of and mag, corresponding to a color range of mag and surface brightness levels of and . Their colours and luminosities are consistent with a diverse set of stellar population properties. Assuming solar and 0.02 Z metallicities we obtain stellar masses in the range…
