To address this, we present deep integral field observations of a sample of 31 low-mass (10<SUP>7.5</SUP> < M<SUB>⋆</SUB> < 10<SUP>9.5</SUP> M<SUB>☉</SUB>) early-type galaxies in the Fornax cluster with the SAMI instrument. For 21 galaxies, our observations are sufficiently deep to construct spatially resolved maps of the stellar velocity and velocity dispersion - for the remaining galaxies, we extract global velocities and dispersions from aperture spectra only. From the kinematic maps, we measure the specific stellar angular momentum λ<SUB>R</SUB> of the lowest mass dE galaxies to date. Combining our observations with early-type galaxy data from the literature spanning a large range in stellar mass, we find that λ<SUB>R</SUB> decreases towards lower stellar mass, with a corresponding increase in the proportion of slowly rotating galaxies in this regime. The decrease of λ<SUB>R</SUB> with mass in our sample dE galaxies is consistent with a similar trend seen in somewhat more massive spiral galaxies from the CALIFA survey. This suggests that the degree of dynamical heating required to produce dEs from low-mass starforming progenitors may be relatively modest and consistent with a broad range of formation mechanisms....STAMPAenArticle10.1093/mnras/staa20422-s2.0-85095413699http://arxiv.org/abs/2007.04492v1https://academic.oup.com/mnras/article/497/2/1571/58706802020MNRAS.497.1571SFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation::PE9_8 Formation and evolution of galaxies
