This study presents the first millimeter continuum mapping observations of two nearby galaxies, the starburst spiral galaxy NGC2146 and the dwarf galaxy NGC2976, at 1.15 mm and 2 m…
NIKA2 observations of starless cores in Taurus and Perseus
C. Kramer, R. Adam, P. Ade +49
Dusty starless cores play an important role in regulating the initial phases of the formation of stars and planets. In their interiors, dust grains coagulate and ice mantles form,…
The stratification of ISM properties in the edge-on galaxy NGC 891 revealed by NIKA2
S. Katsioli, E. M. Xilouris, C. Kramer +60
As the millimeter wavelength range remains a largely unexplored spectral region for galaxies, the IMEGIN large program aims to map the millimeter continuum emission of 22 nearby ga…
PDRs4All IV. An embarrassment of riches: Aromatic infrared bands in the Orion Bar
Ryan Chown, Ameek Sidhu, Els Peeters +136
(Abridged) Mid-infrared observations of photodissociation regions (PDRs) are dominated by strong emission features called aromatic infrared bands (AIBs). The most prominent AIBs ar…
PDRs4All II: JWST's NIR and MIR imaging view of the Orion Nebula
Emilie Habart, Els Peeters, Olivier Berné +139
The JWST has captured the most detailed and sharpest infrared images ever taken of the inner region of the Orion Nebula, the nearest massive star formation region, and a prototypic…
FAUST X: Formaldehyde in the Protobinary System [BHB2007] 11: Small Scale Deuteration
Lucy Evans, Charlotte Vastel, Francisco Fontani +16
Context. Deuterium in H-bearing species is enhanced during the early stages of star formation, however, only a small number of high spatial resolution deuteration studies exist tow…
