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…
GATOS IX: A Detailed Assessment and Treatment of Emission Line Contamination in JWST/MIRI Images of Nearby Seyfert Galaxies
Steph Campbell, David J. Rosario, Houda Haidar +17
Broadband mid-infrared (MIR) imaging with high spatial resolution is useful to study extended dust structures in the circumnuclear regions of nearby AGN. However, broadband imaging…
Polycyclic Aromatic Hydrocarbons (PAHs) in the High-redshift Universe: Prospect of the PRIMA FIRESS low-resolution spectroscopy
Ilsang Yoon, Brandon Hensley, Thomas S. -Y. Lai +6
The integrated luminosity from the features of the polycyclic aromatic hydrocarbons (PAHs) exceeds the luminosity from atomic and molecular emission lines in the star-forming regio…
Low D/H ratio for benzonitrile in TMC-1: Implication for the origin of polycyclic aromatic hydrocarbons in cold dark clouds
A. L. Steber, J. Janeiro, C. Cabezas +9
Radioastronomical observations have recently discovered PAHs of moderate size (up to 24 carbon atoms) in cold dark clouds, although it is currently unknown whether they are formed…
JWST interferometric imaging reveals the dusty disk obscuring the supermassive black hole of the Circinus galaxy
Enrique Lopez-Rodriguez, Joel Sanchez-Bermudez, Omaira Gonzalez-Martin +6
The dusty and molecular torus is one of the most elusive structures surrounding supermassive black holes, yet its importance is unequivocal for understanding feedback and accretion…
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{…
JWST MIRI reveals the diversity of nuclear mid-infrared spectra of nearby type-2 quasars
C. Ramos Almeida, I. Garcia-Bernete, M. Pereira-Santaella +14
Type-2 quasars (QSO2s) are active galactic nuclei (AGN) seen through a significant amount of dust and gas that obscures the central supermassive black hole and the broad line regio…
JWST reveals the diversity of nuclear obscuring dust in nearby AGN: nuclear isolation of MIRI/MRS datacubes and continuum spectral fitting
Omaira González-Martín, Daniel J. Díaz-González, Mariela Martínez-Paredes +22
We investigate the capabilities of the mid-infrared instrument (MIRI) of James Webb Space Telescope (JWST) to advance our knowledge of AGN dust using the spectral fitting technique…
