The SAMI Galaxy Survey:stellar population gradients of central galaxies

We examine the stellar population radial gradients (age, metallicity, and [α/Fe]) of 96 passive central galaxies up to ∼2 R e in the SAMI Galaxy Survey. The targeted groups have a halo mass range of 11 < log( M 200 / M ⊙ ) < 15 . The main goal of this work is to determine whether central galax...

Description
Summary:We examine the stellar population radial gradients (age, metallicity, and [α/Fe]) of 96 passive central galaxies up to ∼2 R e in the SAMI Galaxy Survey. The targeted groups have a halo mass range of 11 < log( M 200 / M ⊙ ) < 15 . The main goal of this work is to determine whether central galaxies have different stellar population properties when compared to similarly massive satellite galaxies.
