The CON-quasar stage of IRAS 07251-0248 E

Eduardo González-Alfonso, Miguel Pereira-Santaella, Ismael García-Bernete +2

ALMA continuum measurements of the local ULIRG IRAS 07251-0248 E at 667m reveal an extremely compact (R < 27 pc) and bright ( >200 K) nucleus with an absorbing foreground e…

Abundant hydrocarbons in a buried galactic nucleus with signs of carbonaceous grain and polycyclic aromatic hydrocarbon processing

I. García-Bernete, M. Pereira-Santaella, E. González-Alfonso +5

Hydrocarbons play a key role in shaping the chemistry of the interstellar medium (ISM), but their enrichment and relationship with carbonaceous grains and polycyclic aromatic hydro…

Silicate emission in a type-2 quasar: JWST/MIRI constraints on torus geometry and radiative feedback

C. Ramos Almeida, A. Asensio Ramos, C. Westerdorp Plaza +13

Type-2 quasars (QSO2s) are AGN seen through a significant amount of dust and gas that obscures the central supermassive black hole and the broad line region. Despite this, recent m…

The PAH 3.4 micron feature as a tracer of shielding in the Orion Bar and NGC 6240

N. Thatte, D. Rigopoulou, F. R. Donnan +8

We have carried out a detailed analysis of the 3.4 micron spectral feature arising from Polycyclic Aromatic Hydrocarbons (PAH), using JWST archival data. For the first time in an e…

JWST reveals cosmic ray dominated chemistry in the local ULIRG IRAS 072510248

G. Speranza, M. Pereira-Santaella, M. Agúndez +7

We analyse the ro-vibrational absorption bands of various molecular cations (HCO, HCNH, and NH) and neutral species (HCN, HNC, and HCN) detected in the \textit{…

Molecular gas excitation and outflow properties of obscured quasars at z0.1

A. Audibert, C. Ramos Almeida, S. García-Burillo +4

To investigate the impact of winds and low-to-moderate power jets on the cold molecular gas reservoirs of AGN, we present high angular resolution ALMA CO(2-1) and CO(3-2) observati…
