Euclid Quick Data Release (Q1): The impact of AGN emission on SED-derived physical properties
Euclid Collaboration, B. Laloux, A. Bongiorno +309
The Euclid Quick Data Release (Q1) is a powerful dataset to study active galactic nuclei (AGN) and their host galaxies. Deriving their physical properties through multi-component s…
Euclid: Disky titans -- surprisingly high star formation efficiency in two brightest group galaxies at
F. Gentile, E. Daddi, D. Elbaz +165
We present the discovery of two disky titans in the first data release of the Euclid satellite. These sources are massive () star-forming (SFR /…
Cosmic-ray impact on optical and mid-infrared emission line diagnostics in NGC 5728
E. Koutsoumpou, J. A. Fernández-Ontiveros, K. M. Dasyra +1
Cosmic rays (CRs), from active galactic nuclei (AGN) jets and supernovae (SNe), serve as a significant feedback mechanism influencing emission lines in narrow line region (NLR) clo…
Cosmic Ray Ionization of Low-Excitation Lines in Active Galactic Nuclei and Starburst Galaxies
E. Koutsoumpou, J. A. Fernández-Ontiveros, K. M. Dasyra +1
Cosmic rays (CRs) can significantly impact dense molecular clouds in galaxies, heating the interstellar medium (ISM) and altering its chemistry, ionization, and thermal properties.…
Euclid: Quick Data Release (Q1) -- Dual AGN in low-mass galaxies
M. Mezcua, B. Laloux, M. Scialpi +164
Dual active galactic nuclei (AGNs) are expected in hierarchical galaxy evolution models, in which low-mass galaxies merge to build more massive ones. While observational evidence f…
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…
