Reionization with star-forming galaxies: insights from the Low-z Lyman Continuum Survey
Maxime Trebitsch, Pratika Dayal, John Chisholm +18
The fraction of ionizing photons escaping from galaxies, , is at the same time a crucial parameter in modelling reionization and a very poorly known quantity, especially a…
Optical spectroscopy of the extremely metal-deficient star-forming galaxy HSC J1631+4426: a test of the strong-line method
T. X. Thuan, N. G. Guseva, Y. I. Izotov
Recently, Kojima and co-authors have reported a record low oxygen abundance, 12+logO/H=6.90+/-0.03 in the low-mass star-forming galaxy HSC J1631+4426. This exceptionally low oxygen…
The Far-Ultraviolet Continuum Slope as a Lyman Continuum Escape Estimator at High-redshift
J. Chisholm, A. Saldana-Lopez, S. Flury +25
Most of the hydrogen in the intergalactic medium (IGM) was rapidly ionized at high-redshifts. While observations have established that reionization occurred, observational constrai…
No correlation of the Lyman continuum escape fraction with spectral hardness
R. Marques-Chaves, D. Schaerer, R. O. Amorín +25
The properties that govern the production and escape of hydrogen ionizing photons (Lyman continuum, LyC; with energies >13.6 eV) in star-forming galaxies are still poorly understoo…
The Low-Redshift Lyman Continuum Survey II: New Insights into LyC Diagnostics
Sophia R. Flury, Anne E. Jaskot, Harry C. Ferguson +44
The Lyman continuum (LyC) cannot be observed at the epoch of reionization (z {\gtrsim} 6) due to intergalactic H I absorption. To identify Lyman continuum emitters (LCEs) and infer…
Decade-long time-monitoring of candidate Luminous Blue Variable Stars in the two very metal-deficient compact dwarf galaxies DDO 68 and PHL 293B
N. G. Guseva, T. X. Thuan, Y. I. Izotov
We have studied the spectral time variations of candidate luminous blue variable stars (cLBV) in two low-metallicity blue compact dwarf galaxies, DDO 68 and PHL 293B. The LBV in DD…
The Low-Redshift Lyman Continuum Survey I: New, Diverse Local Lyman-Continuum Emitters
Sophia R. Flury, Anne E. Jaskot, Harry C. Ferguson +44
The origins of Lyman continuum (LyC) photons responsible for the reionization of the universe are as of yet unknown and highly contested. Detecting LyC photons from the epoch of re…
The Low-Redshift Lyman Continuum Survey. Unveiling the ISM properties of low- Lyman continuum emitters
Alberto Saldana-Lopez, Daniel Schaerer, John Chisholm +24
Combining 66 ultraviolet (UV) spectra and ancillary data from the Low-Redshift Lyman Continuum Survey (LzLCS) and 23 LyC observations by earlier studies, we form a statistical samp…
