Do galaxy global relationships emerge from local ones? The SDSS IV MaNGA surface mass density-metallicity relation

Jorge K. Barrera-Ballesteros, Timothy M. Heckman, Guangtun B. Zhu +12

We present the stellar surface mass density {\it vs.} gas metallicity (${\Sigma }_{\ast }-Z$) relation for more than 500,000 spatially-resolved star-forming resolution elements (spaxels) from a…
