Not So Isolated: Green Pea Galaxies in Overdense Environments revealed by VLT/MUSE

A. Arroyo-Polonio, J. M. Vílchez, 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…

Wild is the wind from low-luminosity AGN: a jet-driven gas bubble blowing out a massive CO-dark outflow in ESO 420-G13

J. A. Fernández-Ontiveros, L. Spinoglio, M. Pereira-Santaella +8

We present JWST/MIRI mid-infrared integral field spectroscopy combined with ALMA CO(2-1) observations of the post-starburst galaxy ESO 420-G13, hosting a low-luminosity AGN. The un…

EGS-z11-R0: a red, dust-rich galaxy at Cosmic Dawn

Giulia Rodighiero, Andrea Ferrara, Michele Catone +16

Context. Galaxies discovered by JWST at z > 10 are predominantly characterized by extremely blue rest-frame UV slopes. Conversely, the existence of dust-reddened systems at such ea…

Chemical enrichment in LINERs from MaNGA. II. Characterizing the shape of their radial metallicity gradients

Borja Pérez-Díaz, José M. Vílchez, Enrique Pérez Montero +3

Chemical abundance radial gradients provide key information on how the processes that affect chemical enrichment of the gas-phase interstellar medium (ISM) act at different galaxy…

Investigating ionising sources and the complex interstellar medium of GHZ2 at

M. Castellano, L. Napolitano, B. Moreschini +27

An accurate characterisation of the physical properties of galaxies at cosmic dawn is key to understanding the origin of the high abundance of UV-bright galaxies at z10. W…

Sulphur abundances in star-forming regions from optical emission lines: A new approach based on photoionization models consistent with the direct method

Enrique Pérez-Montero, Borja Pérez-Díaz, José M. Vílchez +5

The derivation of sulphur chemical abundances in the gas-phase of star-forming galaxies is explored in this work, using the emission lines produced in these regions in the optical…
