Declining metallicity and extended HeII in the outflow of an epoch of reionization analogue galaxy
M. J. Hamel-Bravo, D. B. Fisher, D. A. Berg +5
We present VLT/X-shooter spectroscopy of the extremely metal-poor starburst galaxy SBS 0335-052E, a nearby (D 54 Mpc) analog of high-redshift systems, probing its outflow up…

Electron temperature relations in low metallicity, diffuse, and extraplanar gas of starburst galaxies
Magdalena J. Hamel-Bravo, Deanne B. Fisher, Danielle A. Berg +6
In this work, we test the validity of - relations in resolved (10-200~pc) measurements of four nearby, low-metallicity (7.25 12+log(O/H) 8.33), low-mass (…

Deciphering spatially resolved Lyman-alpha profiles in reionization analogs: the Sunburst Arc at cosmic noon
Erik Solhaug, Hsiao-Wen Chen, Mandy C. Chen +7
The hydrogen Lyman-alpha (Lya) emission line, the brightest spectral feature of a photoionized gas, is considered an indirect tracer of the escape of Lyman continuum (LyC) photons,…
