Resolving the Multiphase Outflow, Shock Signatures, and PAHs in the AGN-Starburst Composite ULIRG F10565+2448 with JWST MIRI/MRS

Kylie Yui Dan, Jerome Seebeck, Sylvain Veilleux +9

We present new James Webb Space Telescope Mid-Infrared Instrument (MIRI) Medium-Resolution Spectrometer (MRS) observations of the nearby ultra-luminous infrared galaxy F10565+2448.…

Molecular Outflows in the Nucleus of the Nearby Compton-thick AGN NGC 3079

Ming-Yi Lin, Anne Medling, Richard Davies +14

We present Northern Extended Millimeter Array (NOEMA) observations of the CO (2-1) molecular gas kinematics in the nearby Compton-thick Seyfert 2 galaxy NGC 3079, with an angular r…

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…

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…

JWST Discovery of High-Velocity Mid-Infrared Ionized Outflows in Ultraluminous Infrared Galaxies F11119+3257 and F05189-2524

Jerome Seebeck, Kylie Yui Dan, Sylvain Veilleux +9

Ultra-fast outflows (UFOs) are thought to be a driving mechanism of large-scale winds driven by active galactic nuclei, which cause significant galactic feedback through quenching…

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{…
