EMPRESS. II. Highly Fe-Enriched Metal-poor Galaxies with $\sim 1.0$ (Fe/O) $_{⊙}$ and $0.02$ (O/H) $_{⊙}$ : Possible Traces of Super Massive ( $> 300 M_{⊙}$ ) Stars in Early Galaxies

Takashi Kojima, Masami Ouchi, Michael Rauch +18

We present element abundance ratios and ionizing radiation of local young low-mass (~ $1 0^{6}$ M_sun) extremely metal poor galaxies (EMPGs) with a 2% solar oxygen abundance (O/H)_su…

EMPRESS. III. Morphology, Stellar Population, and Dynamics of Extremely Metal Poor Galaxies (EMPGs): Are EMPGs Local Analogs of High- $z$ Young Galaxies?

Yuki Isobe, Masami Ouchi, Takashi Kojima +16

We present the morphology and stellar population of 27 extremely metal poor galaxies (EMPGs) at $z \sim 0$ with metallicities of 0.01--0.1 Z $_{⊙}$ . We conduct multi-component sur…
