"The episodic star-formation histories of dwarf galaxies with present-day stellar masses 10^9 solar masses present a challenge to our current understanding of galaxy formation and evolution. Hydrodynamical simulations predict that star formation in these galaxies was very burst-like in the past, with feedback in the form of supernovae and winds that heat and deplete the central cold gas reservoirs. Repeated starburst events have been cited as the driving force behind intense feedback that can change the central dark matter profile, potentially addressing one of the principal challenges to the standard Cold Dark Matter cosmological model. Until recently, dwarf galaxies have only been studied in the local universe. Here we use a combination of multiwavelength photometry and near-IR grism spectroscopy to identify an abundant population of extreme emission line galaxies (EELGs) at z > 1. Sophisticated modeling of their spectral energy distributions reveals that EELGs, selected only based on their large equivalent widths, have low stellar masses. Our high-resolution follow-up spectroscopy in the near-IR shows that the emission lines are very narrow, implying low total dynamical masses. Emission line ratios are consistent with low gas-phase metallicities and also demonstrate that the strong emission comes from hot young stars. Therefore, these objects show all the signatures of dwarf galaxies at z > 1. By developing a novel method to detect strong emission line sources in grism spectroscopic data, we trace the evolution in the number density of EELGs with cosmic time, observing that they are more than an order of magnitude more common at z = 2 than locally. This observationally supports the importance of bursty star-formation in low-mass galaxies at z > 1, implying that most stars in today’s dwarf galaxies formed in a small number of these early bursts. Taken together, these results constitute the first comprehensive observational study of dwarf galaxies at high redshift."^^ . "2015" . . . . . . . "Michael Vincent"^^ . "Maseda"^^ .
