Dust production in the harsh environment of Sgr A* - MIRI/JWST observation of the O-rich asymptotic giant branch star IRS~3
F. Peißker, M. García Marín, A. Eckart +18
Studies of the interstellar medium (ISM) have frequently revealed signatures of the dust produced in the envelopes of asymptotic giant branch (AGB) stars, demonstrating a connectio…
MICONIC: The spatial relationship between star formation and the AGN in Centaurus A revealed by JWST/MIRI
O. C. Jones, M. L. Jones, D. Dicken +21
Centaurus A (Cen A), the nearest active radio galaxy, hosts a warped dust disc formed in a gas-rich merger. We present JWST/MIRI imaging in three filters, F560W, F770W, and F1130W,…
JWST observations of photodissociation regions. IV. Carbonaceous emission band sub-components in NGC 7023 have distinct spatial distributions
D. Van De Putte, K. D. Gordon, K. Misselt +10
We analyze JWST spectroscopy of the northwest filament of NGC7023, where the relatively soft radiation field results in a photodissociation region with an extended atomic hydrogen…
MICONIC: JWST/MIRI-MRS reveals heavily reprocessed PAH emission in the circum-nuclear disc of Centaurus A
L. Pantoni, M. Baes, L. Decin +23
Polycyclic aromatic hydrocarbons (PAHs) are key dust components in galaxies and play a fundamental role in the physics of the interstellar medium (ISM), yet their response to AGN f…
JWST observations of photodissociation regions III. Dust modelling at the illuminated edge of the Horsehead PDR
M. Elyajouri, A. Abergel, N. Ysard +19
Carbonaceous nano-grains are a significant component of interstellar dust and dominate the mid-infrared emission of photodissociation regions (PDRs). We study the evolution of nano…
