Reionization driven by the few: the ionizing budget of galaxies at z=5-10 from JWST/NIRSpec

Emma Giovinazzo, Pascal A. Oesch, Anne Verhamme +5

The sources responsible for the Epoch of Reionization (EoR), the last major phase transition of the Universe, remain highly elusive. While JWST has begun to illuminate the properti…

Resolving the Unresolved Galactic Winds in Multi-phase Models. I. Methodology and Application

Xinfeng Xu, Drummond Fielding, Timothy Heckman +12

Galactic winds shape galaxy evolution; however, the outflowing gas is complex: it consists of multiple ionization phases, and its properties vary spatially. Therefore, methods that…

Power-law Emission-line Wings and Radiation-Driven Superwinds in Local Lyman Continuum Emitters

Lena Komarova, Sally Oey, Rui Marques-Chaves +27

We investigate broad emission-line wings, reaching , observed in 26 galaxies with Lyman continuum (LyC) observations, primarily from the Low-redshift Lyman C…

Lyman Continuum leakage from massive leaky starbursts: A different class of emitters?

Namrata Roy, Timothy Heckman, Alaina Henry +11

The origin of Lyman Continuum (LyC) photons responsible for reionizing the universe remains a mystery, with the fraction of escaping LyC photons from galaxies at z 6 to 12 be…

Breaking Through the Cosmic Fog: JWST/NIRSpec Constraints on Ionizing Photon Escape in Reionization-Era Galaxies

Emma Giovinazzo, Pascal A. Oesch, Andrea Weibel +15

The escape fraction of Lyman continuum photons (fesc(LyC)) is the last key unknown in our understanding of cosmic reionization. Directly estimating the escape fraction (fesc) of io…
