We suggest that low optical depth in the Lyman continuum (LyC) may relate the Lyα emission, C ii and Si ii absorption, and C ii* and Si ii* emission seen in high-redshift galaxies. We base this analysis on Hubble Space Telescope Cosmic Origins Spectrograph spectra of four Green Pea (GP) galaxies, which may be analogs of z > 2 Lyα emitters (LAEs). In the two GPs with the strongest Lyα emission, the Lyα line profiles show reduced signs of resonant scattering. Instead, the Lyα profiles resemble…

New Insights on Lyα and Lyman Continuum Radiative Transfer in the Greenest Peas
As some of the only Lyman continuum (LyC) emitters at z ∼ 0, Green Pea (GP) galaxies are possible analogs of the sources that reionized the universe. We present HST COS spectra of 13 of the most
Kinematics and Optical Depth in the Green Peas: Suppressed Superwinds in Candidate LyC Emitters
By clearing neutral gas away from a young starburst, superwinds may regulate the escape of Lyman continuum (LyC) photons from star-forming galaxies. However, models predict that superwinds may not
Lyα Emission from Green Peas: The Role of Circumgalactic Gas Density, Covering, and Kinematics
We report Hubble Space Telescope/Cosmic Origins Spectrograph observations of the Lyα emission and interstellar absorption lines in a sample of 10 star-forming galaxies at z ∼ 0.2. Selected on the

Lyman-α spectral properties of five newly discovered Lyman continuum emitters
Aims. We have recently reported the discovery of five low redshift Lyman continuum (LyC) emitters (LCEs) with absolute escape fractions f esc LyC that range from 6 to 13%, higher than previously

Abstract The Lyman alpha emission line (Lyα) of neutral hydrogen (Hi) is intrinsically the brightest emission feature in the spectrum of astrophysical nebulae, making it a very attractive
THE LYMAN ALPHA REFERENCE SAMPLE. V. THE IMPACT OF NEUTRAL ISM KINEMATICS AND GEOMETRY ON Lyα ESCAPE
We present high-resolution far-UV spectroscopy of the 14 galaxies of the Lyα Reference Sample; a sample of strongly star-forming galaxies at low redshifts (0.028 < z < 0.18). We compare the derived
INDIRECT EVIDENCE FOR ESCAPING IONIZING PHOTONS IN LOCAL LYMAN BREAK GALAXY ANALOGS
A population of early star-forming galaxies is the leading candidate for the re-ionization of the universe. It is still unclear, however, what conditions and physical processes would enable a
Photoionization Models for the Semi-Forbidden C III] 1909 Emission in Star-Forming Galaxies
The increasing neutrality of the intergalactic medium at z > 6 suppresses Lyα emission, and spectroscopic confirmation of galaxy redshifts requires the detection of alternative ultraviolet lines. The
A CLOSE COMPARISON BETWEEN OBSERVED AND MODELED Lyα LINES FOR z ∼ 2.2 Lyα EMITTERS
We present the results of an Lyα profile analysis of 12 Lyα emitters (LAEs) at z ∼ 2.2 ?> with high-resolution Lyα spectra. We find that all 12 objects have an Lyα profile with the main peak redward
