Context. The mass-metallicity relationship (MMR) of star-forming galaxies is well-established, however there is still some disagreement with respect to its exact shape and its possible dependence on other observables. Aims.We measure the MMR in the G... Read More about Galaxy and mass assembly (GAMA): The mass-metallicity relationship.

Journal Article
Penny, S. J., Pimbblet, K. A., Conselice, C. J., Brown, M. J., Grützbauch, R., & Floyd, D. J. (2012). Tidal interactions at the edge of the Local Group: New evidence for tidal features in the antlia Dwarf galaxy. Astrophysical journal. Letters, 758(2), Article L32. https://doi.org/10.1088/2041-8205/758/2/L32

Using deep B-band imaging down to μ B = 26 mag arcsec -2 , we present evidence for tidal tails in the Antlia Dwarf galaxy, one of the most distant members of the Local Group. This elongation is in the direction of Antlia's nearest neighbor, the Magel...
