On Extending the Mass-Metallicity Relation of Galaxies by 2.5 Decades in Stellar Mass

Astrophys.J.647:970-983,2006 We report 4.5 micron luminosities for 27 nearby (D < 5 Mpc) dwarf irregular galaxies measured with the Spitzer Infrared Array Camera. We have constructed the 4.5 micron luminosity-metallicity (L-Z) relation for 25 dwarf galaxies with secure distance and interstellar m...
