Shocked, Heated, and Now Resolved: H excitation in the low-luminosity AGN at M58 core with JWST
I. E. López, E. Bertola, V. Reynaldi +11
We present JWST NIRSpec and MIRI MRS observations of the central kiloparsec of M58 (NGC 4579), a nearby LINER galaxy hosting a low-luminosity AGN (LLAGN; $L_\mathrm{bol} \sim 10^{4…
J-PAS: Discovery of RaJav, a bright spatially extended Ly Nebula at z=2.25
P. T. Rahna, M. Akhlaghi, J. A. Fernández-Ontiveros +29
We report the discovery of a massive and potentially largest Ly Nebula, RaJav, at z=2.25, associated with a quasar pair: the bright SDSS~J162029.07+433451.1 (hereafter J1620+433…
Black hole accretion, star formation, and chemical evolution with PRIMA/FIRESS spectroscopy: toward the cosmic noon and beyond
Juan Antonio Fernández-Ontiveros, Luigi Spinoglio, Tohru Nagao
The PRobe far-Infrared Mission for Astrophysics (PRIMA) will deliver the first comprehensive view of the obscured side of star formation and black hole accretion that dominates gal…
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…
Exploring the hardness of the ionizing radiation with the infrared softness diagram. II. Bimodal distributions in both the ionizing continuum slope and the excitation in active galactic nuclei
E. Pérez-Montero, J. A. Fernández-Ontiveros, B. Pérez-Díaz +2
After exploring the infrared softness diagram to characterize the hardness of the incident ionizing radiation in star-forming regions, we exploit the availability of high-excitatio…
J-PLUS: Spectroscopic validation of H emission line maps in spatially resolved galaxies
P. T. Rahna, M. Akhlaghi, C. López-Sanjuan +22
We present a dedicated automated pipeline to construct spatially resolved emission H+[NII] maps and to derive the spectral energy distributions (SEDs) in 12 optical filters (fiv…
Andromeda's tenuous veil: A likely Milky Way nebula projected toward M31
A. Lumbreras-Calle, J. A. Fernández-Ontiveros, R. Infante-Sainz +10
A large, faint nebula was unexpectedly discovered near M31 using narrowband [O III] images. Its apparent size and the lack of a clear counterpart at other wavelengths make it uniqu…
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.…
J-PLUS: Bayesian object classification with a strum of BANNJOS
A. del Pino, C. López-Sanjuan, A. Hernán-Caballero +22
With its 12 optical filters, the Javalambre-Photometric Local Universe Survey (J-PLUS) provides an unprecedented multicolor view of the local Universe. The third data release (DR3)…
Chemical abundances and deviations from the solar S/O ratio in the gas-phase ISM of galaxies based on infrared emission lines
Borja Pérez-Díaz, Enrique Pérez-Montero, Juan A. Fernández-Ontiveros +3
The infrared (IR) range is extremely useful in the context of chemical abundance studies of the gas-phase interstellar medium (ISM) due to the large variety of ionic species traced…
