Not So Isolated: Green Pea Galaxies in Overdense Environments revealed by VLT/MUSE
A. Arroyo-Polonio, J. M. VÃlchez, J. Iglesias-Páramo +9
Context. Green Pea galaxies (GPs) are local starburst galaxies serving as analogues for high-redshift star-forming galaxies, particularly Lyman continuum leakers. It remains debate…
The Collective Voice of Ly Emitters: Insights from JWST Stacked Spectroscopy
R. Tripodi, L. Napolitano, L. Pentericci +22
We present a spatially resolved stacked analysis of 287 LAEs at observed with JWST/NIRSpec prism spectroscopy. By constructing a two-dimensional stack from public surveys (CA…
J-PAS: First Identification, Physical Properties and Ionization Efficiency of Extreme Emission Line Galaxies
A. Giménez-Alcázar, R. AmorÃn, J. M. VÃlchez +32
Extreme emission line galaxies (EELGs) are key tracers of intense star formation and potential analogues of the sources that reionized the early Universe. Their low-redshift counte…
New clues on the extended HeII ionization in IZw18 from GTC/MEGARA and JWST/MIRI
A. Arroyo-Polonio, C. Kehrig, J. M. VÃlchez +5
IZw18 is one of the lowest-metallicity star-forming galaxies known at z0, considered a unique local analogue of the first galaxies. The origin of its hard ionizing continuum,…
