Extended coronal line emission and new clues to a possible dual AGN in the merger J1356+1026

M. Bianchin, C. Ramos Almeida, O. González-Martín +12

Merging luminous galaxies are ideal laboratories to study some of the most extreme astrophysical phenomena. The local (z=0.1232) obscured quasar J1356+1026 has two nuclei, North an…

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…

The Galaxy Activity, Torus, and outflow Survey (GATOS) XIII: Coupling Driven H2 Excitation in Seyferts

Daniel E. Delaney, Erin K. S. Hicks, Lulu Zhang +31

We utilize JWST/MIRI IFU observations from the Galaxy Activity, Torus and Outflow Survey (GATOS) to investigate the diverse range of ionized outflow rates of obscured AGN with simi…

The Galaxy Activity, Torus, and Outflow Survey (GATOS): N. Unveiling physical processes in local active galaxies. Unsupervised hierarchical clustering of JWST MIRI/MRS observations

L. Hermosa Muñoz, J. R. González Fernández, A. Alonso-Herrero +23

With the rise of the integral field spectroscopy, we are currently dealing with large amounts of spatially resolved data, whose analysis has become challenging, especially when obs…

QSOFEED: Investigating warm molecular, low- and high-ionization atomic gas in six type-2 quasars with GTC/EMIR

P. H. Cezar, M. Coloma Puga, C. Ramos Almeida +6

We present long-slit near-infrared spectroscopic observations of six nearby (z0.1) radio-quiet type-2 quasars (QSO2s) from the Quasar Feedback (QSOFEED) sample. They have bol…

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…
