Emma Kirby, Helmut Jerjen, Stuart Ryder, Simon Driver
TL;DR
This paper provides deep near-infrared imaging of 56 local galaxies, deriving their global properties and exploring multiwavelength relations to understand galaxy mass limits.
Contribution
It offers the deepest near-IR data for local galaxies and combines it with other wavelengths to study galaxy properties and baryonic mass constraints.
Findings
Derived total magnitudes and stellar masses for 56 galaxies.
Analyzed HI mass-to-light ratios across the sample.
Investigated maximum baryonic mass in galaxies.
Abstract
We present near-IR, deep (4 mag deeper than 2MASS) imaging of 56 Local Volume galaxies. Global parameters such as total magnitudes and stellar masses have been derived and the new near-IR data combined with existing 21cm and optical B-band data. We present multiwavelength relations such as the HI mass-to-light ratio and investigate the maximum total baryonic mass a galaxy can have.
