A faint M Lyman-continuum leaker candidate in the epoch of reionization: Unprecedented Ly properties at z=5.725
M. Messa, E. Vanzella, T. Morishita +10
We report the unprecedented Ly properties of AMORE6, an extremely metal-poor (), low-mass (), and ultracompact (effe…
The SPHINX public data release. II. Using low-ionisation absorption lines and dust attenuation to predict Lyman continuum escape
Valentin Mauerhofer, Jérémy Blaizot, Thibault Garel +11
Low-ionisation state (LIS) absorption lines, such as SiII 1526, are widely used to trace the properties of the interstellar medium (ISM) in galaxies. These lines provide crucial in…
Nitrogen abundances in star-forming galaxies 2.2 Gyr after the Big Bang are not elevated
D. Schaerer, Y. I. Izotov, R. Marques-Chaves +22
Using deep medium-resolution JWST rest-optical spectra of a sample of typical star-forming galaxies (Lyman break galaxies and Lyman- emitters) from the LyC22 survey at $z \sim…
A great diversity of spectral shapes in the ionising spectra of z ~ 0.6-1 galaxies revealed by HST/COS and possible detection of nebular LyC emission
Y. I. Izotov, D. Schaerer, G. Worseck +4
We present observations of eleven compact star-forming galaxies in the redshift range z = 0.6145 - 1.0053, with the Cosmic Origins Spectrograph (COS) on board the Hubble Space Tele…
Intergalactic Medium Tomography with the Sunburst Arc
Michelle A. Berg, John Chisholm, J. Xavier Prochaska +9
Gravitational lensing has transformed the field of gas tomography in the intergalactic medium (IGM) and circumgalactic medium (CGM). Here we use the brightest lensed galaxy identif…
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…
