Investigating the ionization mechanisms powering the extreme emission lines in metal-poor galaxies

C. Daoutis, V. Lebouteiller, D. Schaerer +11

Extreme emission metal-poor galaxies (EEMPGs) are excellent local laboratories for understanding the extreme physical conditions and ionizing radiation fields in the early Universe…

Enhancing the performance and capabilities of the MIRI instrument on JWST

S. Kendrew, M. Engesser, K. Rowlands +23

MIRI, the Mid-Infrared Instrument on the James Webb Space Telescope, is the only instrument sensitive to wavelengths longward of 5 um on the observatory. In this regime, MIRI bring…

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…

PDRs4All: XVIII. The evolution of the PAH ionisation and PAH size distribution across the Orion Bar

Alexandros Maragkoudakis, Christiaan Boersma, Els Peeters +25

We investigate the evolution of the PAH population's charge state and size across key physical zones in the Orion Bar, which include the HII region, the atomic PDR (APDR), and thre…

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…

JWST observations of photodissociation regions: II. Warm molecular Hydrogen spectroscopy in the Horsehead nebula

M. Zannese, P. Guillard, A. Abergel +16

H2 is the most abundant molecule in the interstellar medium and is a useful tool to study photodissociation regions, where radiative feedback from massive stars on molecular clouds…
