J1154+2443: a low-redshift compact star-forming galaxy with a 46 per cent leakage of Lyman continuum photons

Y. I. Izotov, D. Schaerer, G. Worseck +5

We report the detection of the Lyman continuum (LyC) radiation of the compact star-forming galaxy (SFG) J1154+2443 observed with the Cosmic Origins Spectrograph (COS) onboard the H…

J0811+4730: the most metal-poor star-forming dwarf galaxy known

Y. I. Izotov, T. X. Thuan, N. G. Guseva +1

We report the discovery of the most metal-poor dwarf star-forming galaxy (SFG) known to date, J0811+4730. This galaxy, at a redshift z=0.04444, has a Sloan Digital Sky Survey (SDSS…

LBT observations of compact star-forming galaxies with extremely high [OIII]/[OII] flux ratios: HeI emission-line ratios as diagnostics of Lyman continuum leakage

Y. I. Izotov, T. X. Thuan, N. G. Guseva

We present Large Binocular Telescope spectrophotometric observations of five low-redshift (z<0.070) compact star-forming galaxies (CSFGs) with extremely high emission-line ratios O…

Do galaxies that leak ionizing photons have extreme outflows?

J. Chisholm, I. Orlitová, D. Schaerer +5

To reionize the early universe, high-energy photons must escape the galaxies that produce them. It has been suggested that stellar feedback drives galactic outflows out of star-for…

The efficiency of ionising photon production and the radiation energy balance in compact star-forming galaxies

Y. I. Izotov, N. G. Guseva, K. J. Fricke +2

We derive apparent and absolute ultraviolet (UV) magnitudes, and luminosities in the infrared (IR) range of a large sample of low-redshift (0<z<1) compact star-forming galaxies (CS…
