The synchrony of production and escape: half the bright Lyα emitters at z ≈ 2 have Lyman continuum escape fractions ≈50
The ionizing photon escape fraction [Lyman continuum (LyC) f esc] of star-forming galaxies
is the single greatest unknown in the reionization budget. Stochastic sightline effects prohibit …

The structure and kinematics of the circumgalactic medium from far-ultraviolet spectra of z≃ 2–3 galaxies
We present new results on the kinematics and spatial distribution of metal-enriched gas
within∼ 125 kpc of star-forming (" Lyman break") galaxies at redshifts 2≲ z≲ 3. In particular …

The thesan project: Lyman-α emission and transmission during the Epoch of Reionization
The visibility of high-redshift Lyman-alpha emitting galaxies (LAEs) provides important
constraints on galaxy formation processes and the Epoch of Reionization (EoR). However …

A characteristic scale for cold gas
M McCourt, SP Oh, R O'Leary… - Monthly Notices of the …, 2018 - academic.oup.com
We find that clouds of optically thin, pressure-confined gas are prone to fragmentation as
they cool below∼ 106 K. This fragmentation follows the lengthscale∼ cst cool, ultimately …

Lyα profile, dust, and prediction of Lyα escape fraction in green pea galaxies
Abstract We studied Lyman-α (Lyα) escape in a statistical sample of 43 Green Peas with
HST/COS Lyα spectra. Green Peas are nearby star-forming galaxies with strong [O iii] λ5007 …

Extreme feedback and the epoch of reionization: clues in the local universe
The source responsible for reionizing the universe at z> 6 remains uncertain. While an
energetically adequate population of star-forming galaxies may be in place, it is unknown …
