Large Binocular Telescope observations of new six compact star-forming galaxies with [NeV] 3426A emission
Y. I. Izotov, T. X. Thuan, N. G. Guseva
We report the discovery of [NeV]3426 emission, in addition to HeII4686 emission, in six compact star-forming galaxies. These observations considerably increase the sample of eight…
J2229+2725: an extremely low-metallicity dwarf compact star-forming galaxy with an exceptionally high [OIII]5007/[OII]3727 flux ratio of 53
Y. I. Izotov, T. X. Thuan, N. G. Guseva
Using the Large Binocular Telescope (LBT)/Multi-Object Dual Spectrograph (MODS), we have obtained optical spectroscopy of one of the most metal-poor dwarf star-forming galaxies (SF…
The Low-redshift Lyman-continuum Survey: [S II]-deficiency and the leakage of ionizing radiation
Bingjie Wang, Timothy M. Heckman, Ricardo Amorín +19
The relationship between galaxy characteristics and the reionization of the universe remains elusive, mainly due to the observational difficulty in accessing the Lyman continuum (L…
Lyman continuum leakage from low-mass galaxies with Mstar < 1.E8 Msun
Y. I. Izotov, G. Worseck, D. Schaerer +5
We present observations with the Cosmic Origins Spectrograph onboard the Hubble Space Telescope of nine low-mass star-forming galaxies at redshifts, z, in the range 0.3179-0.4524,…
