cds-question@unistra.frgalaxiesinfrared-sourceshst-photometryline-intensitiesWe identify an abundant population of extreme emission-line galaxies (EELGs) at redshift z~1.7 in the Cosmic Assembly Near-IR Deep Extragalactic Legacy Survey imaging from Hubble Space Telescope/Wide Field Camera 3 (HST/WFC3). Sixty-nine EELG candidates are selected by the large contribution of exceptionally bright emission lines to their near-infrared broadband magnitudes. Supported by spectroscopic confirmation of strong [OIII] emission lines - with rest-frame equivalent widths ~1000{AA} - in the four candidates that have HST/WFC3 grism observations, we conclude that these objects are galaxies with ~10^8^M_{sun}_ in stellar mass, undergoing an enormous starburst phase with M_*_/(dM/dt)_*_ of only ~15Myr. These bursts may cause outflows that are strong enough to produce cored dark matter profiles in low-mass galaxies. The individual star formation rates and the comoving number density (3.7x10^-4^Mpc^-3^) can produce in ~4Gyr much of the stellar mass density that is presently contained in 10^8^-10^9^M_{sun}_ dwarf galaxies. Therefore, our observations provide a strong indication that many or even most of the stars in present-day dwarf galaxies formed in strong, short-lived bursts, mostly at z>1.2011ApJ...742..111Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/742/111CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/hst : HST Archived Exposures Catalog (STScI, 2007)II/261 : GOODS initial results (Giavalisco+, 2004)J/ApJS/203/24 : Parameters of galaxies in CANDELS (van der Wel+, 2012)J/AJ/141/14 : HST WFC3 ERS : emission-line galaxies (Straughn+, 2011)J/ApJ/737/71 : The [OIII] emission line in SDSS AGNs (Zhang+, 2011)J/ApJS/192/5 : ELGs from HETDEX pilot survey (Adams+, 2011)J/AJ/141/64 : PEARS emission-line galaxies spectroscopy (Xia+, 2011)J/AJ/138/1022 : ELGs from HST PEARS survey (Straughn+, 2009)J/ApJ/668/853 : Spectroscopy of UltraStrong ELGs (Kakazu+, 2007)J/MNRAS/365/454 : Emission line analysis of HII galaxies (Hoyos+, 2006)J/AJ/130/2584 : KISS emission-line galaxy candidates.
