The core of the problem: Physical limits of the core-Sérsic model
Maarten Baes
The core-Sérsic model is the standard tool for describing partially depleted stellar cores in massive early-type galaxies, yet its physical admissibility has rarely been examined.…
Spatially-resolved interstellar dust properties in the face-on spiral galaxy M 99 as observed by NIKA2
L. Pantoni, F. Galliano, S. C. Madden +62
Large dust grains in thermal equilibrium dominate the far-infrared and contribute to the millimetre continuum of star-forming galaxies, but constraining their properties is difficu…
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…
