CO-to-H $_{2}$ conversion factor and grain size distribution through the analysis of $α_{CO}$ - $q_{PAH}$ relation

I-Da Chiang, Hiroyuki Hirashita, Jeremy Chastenet +5

The CO-to-H $_{2}$ conversion factor ( $α_{CO}$ ) is expected to vary with dust abundance and grain size distribution through the efficiency of shielding gas from CO-dissociation…

JWST MIRI and NIRCam observations of NGC 891 and its circumgalactic medium

Jérémy Chastenet, Ilse De Looze, Monica Relaño +37

We present new JWST observations of the nearby, prototypical edge-on, spiral galaxy NGC 891. The northern half of the disk was observed with NIRCam in its F150W and F277W filters.…

Accurate Simultaneous Constraints on the Dust Mass, Temperature and Emissivity Index of a Galaxy at Redshift 7.31

Hiddo Algera, Hanae Inami, Ilse De Looze +21

We present new multi-frequency ALMA continuum observations of the massive [ $lo g_{10} (M_{⋆} / M_{⊙}) = 10. 3_{- 0.2}^{+ 0.1}$ ], UV-luminous [ $M_{UV} = - 21.7 \pm 0.2$ ] $z=7.31…
