MICONIC: Dual active galactic nuclei, star formation, and ionised gas outflows in NGC 6240 seen with MIRI/JWST
L. Hermosa Muñoz, A. Alonso-Herrero, A. Labiano +19
As part of the guaranteed time observations program Mid-Infrared Characterization Of Nearby Iconic galaxy Centers (MICONIC), we used the medium-resolution spectrometer (MRS) of the…
H absorption and emission in local U/LIRGs with JWST/NIRSpec: Evidence for high H ionization rates
Miguel Pereira-Santaella, Eduardo González-Alfonso, Ismael García-Bernete +6
We study the 3.4-4.4m fundamental rovibrational band of H3+, a key tracer of the ionization of the molecular interstellar medium (ISM), in a sample of 12 local (d< 400 Mpc) ultr…
A biconical ionised gas outflow and evidence for positive feedback in NGC 7172 uncovered by MIRI/JWST
L. Hermosa Muñoz, A. Alonso-Herrero, M. Pereira-Santaella +35
We present observations of the type-2 Seyfert NGC7172 obtained with the medium-resolution spectrometer (MRS) of the Mid-Infrared Instrument (MIRI) on board of the JWST. This galaxy…
Polycyclic Aromatic Hydrocarbon Emission in Galaxies as seen with JWST
Dimitra Rigopoulou, Fergus R. Donnan, Ismael García-Bernete +6
We present a systematic study of mid-infrared spectra of galaxies including star-forming galaxies and Active Galactic Nuclei observed with JWST MIRI-MRS and NIRSpec-IFU. We focus o…
Extinction and AGN over host galaxy contrast effects on the optical spectroscopic classification of AGN
L. Barquín-González, S. Mateos, F. J. Carrera +9
The optical spectroscopic classification of active galactic nuclei (AGN) into type 1 and type 2 can be understood in the frame of the AGN unification models. However, it remains un…
Extended high-ionization [MgIV] emission tracing widespread shocks in starbursts seen by JWST /NIRSpec
Miguel Pereira-Santaella, Ismael García-Bernete, Eduardo González-Alfonso +6
We report the detection of extended (>0.5-1kpc) high-ionization [MgIV] 4.487 m (80 eV) emission in four local luminous infrared galaxies observed with JWST/NIRSpec. Excluding th…
Dust beyond the torus: Revealing the mid-infrared heart of local Seyfert ESO 428-G14 with JWST/MIRI
Houda Haidar, David J. Rosario, Almudena Alonso-Herrero +34
Polar dust has been discovered in a number of local Active Galactic Nuclei (AGN), with radiation-driven torus models predicting a wind to be its main driver. However, little is kno…
AGN feedback in the Local Universe: multiphase outflow of the Seyfert galaxy NGC 5506
Federico Esposito, Almudena Alonso-Herrero, Santiago García-Burillo +21
We present new optical GTC/MEGARA seeing-limited (0.9") integral-field observations of NGC 5506, together with ALMA observations of the CO(3-2) transition at a 0.2" (25 pc) resolut…
Structures Of Dust and gAs (SODA): Constraining the innermost dust properties of II Zw96 with JWST observations of HO and CO
I. García-Bernete, M. Pereira-Santaella, E. González-Alfonso +4
We analyze JWST NIRSpecMIRI/MRS observations of the infrared (IR) gas-phase molecular bands of the most enshrouded source (D1) within the interacting system and luminous IR gala…
