Abstract

Studying the mechanisms governing enhanced star formation in dwarf galaxies is essential to understand how they assemble and evolve. A rare subset of local starbursting dwarfs that look clumpy and highly turbulent can provide new insights on how disks are assembled in the modern Universe. As in early galaxies, gas accretion - induced by mergers or gravitational instabilities - and strong SNe feedback, have been suggested as common drivers as well. However, essential pieces of information are missing. Here we propose to obtain unbiased, 2D high quality spectroscopic observations with GMOS-IFU. These deep, high S/N data tracing both star formation and gas kinematics, are intended to spatially resolve - at kpc scales - the main kinematic components identified in Halpha, including narrow and broad emission.
