TL;DR
This paper introduces the MaNDala sample, the largest homogeneous integral field spectroscopy collection of dwarf galaxies, providing detailed photometric and spectroscopic analysis to study their properties, formation, and evolution.
Contribution
It presents the MaNDala dwarf galaxy sample with comprehensive photometric and spectroscopic data, filling gaps in size-mass relations and analyzing star formation histories.
Findings
MaNDala includes 136 dwarf galaxies with diverse properties.
Most galaxies are star-forming late-type with specific structural parameters.
The size-mass relation flattens at certain stellar masses, indicating a transition in galaxy properties.
Abstract
We present the MaNGA Dwarf galaxy, MaNDala, Value-Added-Catalog, VAC, from the final release of the Sloan Digital Sky Survey-IV program. MaNDala consists of 136 randomly selected bright dwarf galaxies with and making it the largest Integral Field Spectroscopy homogeneous sample of dwarf galaxies. We release a photometric analysis of the and broadband imaging based on the DESI Legacy Imaging Surveys as well as the spectroscopic analysis based on the Pipe3D SDSS-IV VAC. Our release includes the surface brightness (SB), geometric parameters and color profiles, S\'ersic fits as well as stellar population properties (such as, stellar ages, metallicities, star formation histories), and emission lines fluxes within the FOV and the effective radii of the galaxies. We find that the majority of the MaNDala galaxies are star forming late-type galaxies…
