A Detailed Look at the Most Obscured Galactic Nuclei in the Mid-Infrared
F. R. Donnan, D. Rigopoulou, I. García-Bernete +6
Context. Compact Obscured Nuclei (CONs) are an extreme phase of galaxy evolution where rapid supermassive black hole growth andor compact star-forming activity is completely obs…
A solar metallicity galaxy at 7? Possible detection of the [N II] 122 m and [O III] 52 m lines
Meghana Killi, Darach Watson, Seiji Fujimoto +9
We present the first detection of the [N II] 122 m and [O III] 52 m lines for a reionisation-epoch galaxy. Based on these lines and previous [C II] 158 m and [O III] 88 $μ…
Torus and polar dust dependence on AGN properties
I. García-Bernete, O. González-Martín, C. Ramos Almeida +8
We present a statistical analysis of the properties of the obscuring material around active galactic nuclei (AGN). This study represents the first of its kind for an ultra-hard X-r…
The Obscured Nucleus and Shocked Environment of VV 114E Revealed by JWST/MIRI Spectroscopy
F. R. Donnan, I. García-Bernete, D. Rigopoulou +5
Compact Obscured Nuclei (CONs) potentially hide extreme supermassive black hole (SMBH) growth behind large column densities of gas/dust. We present a spectroscopic analysis of the…
A high angular resolution view of the PAH emission in Seyfert galaxies using JWST/MRS data
I. García-Bernete, D. Rigopoulou, A. Alonso-Herrero +16
Polycyclic Aromatic Hydrocarbons (PAHs) are carbon-based molecules that are ubiquitous in a variety of astrophysical objects and environments. In this work, we use JWST/MIRI MRS sp…
Probing computational methodologies in predicting mid-infrared spectra for large polycyclic aromatic hydrocarbons
Boutheïna Kerkeni, Ismael García-Bernete, Dimitra Rigopoulou +3
We extend the prediction of vibrational spectra to large sized polycyclic aromatic hydrocarbon (PAH) molecules comprising up to \sim 1500 carbon atoms by evaluating the efficiency…
Physics of ULIRGs with MUSE and ALMA: PUMA IV. No tight relation between cold molecular outflow rates and AGN luminosities
I. Lamperti, M. Pereira-Santaella, M. Perna +11
We study molecular outflows in a sample of 25 nearby (z< 0.17, d<750 Mpc) ULIRG systems (38 individual nuclei) as part of the "Physics of ULIRGs with MUSE and ALMA" (PUMA) survey,…
Stellar and black hole assembly in z<0.3 infrared-luminous mergers: intermittent starbursts vs. super-Eddington accretion
Duncan Farrah, Andreas Efstathiou, Jose Afonso +20
We study stellar and black hole mass assembly in a sample of 42 infrared-luminous galaxy mergers at z<0.3 by combining results from radiative transfer modelling with archival measu…
A new look at local ultraluminous infrared galaxies: the atlas and radiative transfer models of their complex physics
A. Efstathiou, D. Farrah, J. Afonso +11
We present the ultraviolet to submillimetre spectral energy distributions (SEDs) of the HERschel Ultra Luminous Infrared Galaxy Survey (HERUS) sample of 42 local ultraluminous infr…
On the Viability of Determining Galaxy Properties from Observations I: Star Formation Rates and Kinematics
Kearn Grisdale, Laurence Hogan, Dimitra Rigopoulou +8
We explore how observations relate to the physical properties of the emitting galaxies by post-processing a pair of merging galaxies from the cosmological, hydrodynamical…
Compact molecular gas emission in local LIRGs among low- and high-z galaxies
E. Bellocchi, M. Pereira-Santaella, L. Colina +12
We present new CO(2-1) observations of a representative sample of 24 local (z0.02) luminous infrared galaxies (LIRGs) obtained at high spatial resolution (100 pc) from ALMA.…
A technique to select the most obscured galaxy nuclei
I. García-Bernete, D. Rigopoulou, S. Aalto +5
Compact obscured nuclei (CONs) are mainly found in local U/LIRGs. In the local Universe, these sources are generally selected through the detection of the HCN-vib (3-2) emission li…
Unveiling the Main Sequence to Starburst Transition Region with a Sample of Intermediate Redshift Luminous Infrared Galaxies
L. Hogan, D. Rigopoulou, S. García-Burillo +8
We present a CO(3-2) study of four systems composed of six (ultra) luminous infrared galaxies (U/LIRGs), located at 0.28 < z < 0.44, that straddle the transition region between reg…
Gas Phase Metallicities of Local Ultra-Luminous Infrared Galaxies Follow Normal Star-Forming Galaxies
Nima Chartab, Asantha Cooray, Jingzhe Ma +9
Despite advances in observational data, theoretical models, and computational techniques to simulate key physical processes in the formation and evolution of galaxies, the stellar…
