The observable characteristics and subsequent evolution of young stellar populations is
dominated by their massive stars. As our understanding of those massive stars and the …

Intergalactic space is filled with a pervasive medium of ionized gas, the intergalactic medium
(IGM). A residual neutral fraction is detected in the spectra of quasistellar objects at both low …

Most of the hydrogen in the intergalactic medium (IGM) was rapidly ionized at high redshifts.
While observations have established that reionization occurred, observational constraints on …

The fraction of hydrogen ionizing photons esca** from galaxies into the intergalactic
medium is a critical ingredient in the theory of reionization. We use two zoomed-in, high …

ABSTRACT We present the Spectroscopic Imaging survey in the near-infrared (near-IR) with
SINFONI (SINS) of high-redshift galaxies. With 80 objects observed and 63 detected in at …

Context. In recent years, a number of Lyman continuum (LyC) leaker candidates have been
found at intermediate redshifts, providing insight into how the Universe was reionised at …

We present a systematic study for ionization state of inter-stellar medium in galaxies at z= 0–
with∼ 140 000 Sloan Digital Sky Survey (SDSS) galaxies and 108 intermediate-to high …

Aims. We propose to infer the output of the ionising continuum-leaking properties of galaxies
based upon their Lyα line profiles. Methods. We carried out Lyα radiation transfer …

Using a complete sample of∼ 300 star-forming galaxies within 11 Mpc of the Milky Way, we
evaluate the consistency between star formation rates (SFRs) inferred from the far ultraviolet …

Context. Identifying the physical mechanisms driving the escape of Lyman continuum (LyC)
photons is crucial for the search of Lyman continuum emitter (LCE) candidates. Aims. To …
