SDSS-IV MaNGA: The MaNGA Dwarf Galaxy Sample

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 $M_{\ast }<10^{9.1}\odot$ and $M_g>-18.5$ making it the largest Integral Field Spectroscopy homogeneous sample of dwarf galaxies. We release a photometric analysis of the $g,r$ and $z$ 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, Sérsic 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 with $⟨n_{\text{Sersic,r}}⟩\sim 1.6$ that are centrals (central/satellite dichotomy). MaNDala covers a large range of SB values (we find 11 candidates of ultra diffuse galaxies and 3 compact ones), filling the gap between classical dwarfs and low-mass galaxies in the Kormendy Diagram and in the size-mass/luminosity relation, whichseems to flatten at $10^8<M_{\ast }/\odot <10^9$ with $⟨R_{e,r}⟩\sim 2.7$ kpc. A large fraction of MaNDala galaxies formed from an early low-metallicity burst of SF but also of late SF events from more metal-enriched gas: half of the MaNDala galaxies assembled $50\%$ of their mass at $⟨z⟩>2$, while the last $20\%$ was at $⟨z⟩<0.3$. Finally, a bending of the sSFR-$M_{\ast }$ relation at $M_{\ast }\sim 10^9\odot$ for the main sequence galaxies seems to be supported by MaNDala.
