Abstract We introduce a prescription for estimating the flux of 7.7 μ m and 11.3 polycyclic aromatic hydrocarbon (PAH) features from broadband JWST/MIRI images. Probing PAH with MIRI imaging data has advantages in field view, spatial resolution, sensitivity compared spectral maps, but comparisons spectra are needed to calibrate these estimations over wide variety environments. For 267 MIRI/MRS independent regions four luminous infrared galaxies (LIRGs) Great Observatories All-sky LIRG Survey...
Context. The main sequence (MS) of star-forming galaxies (SFGs) is the tight relation between galaxy stellar mass ( M ⋆ ) and its star formation rate (SFR) was observed up to z ∼ 6. MS can be used as a reference for understanding differences among galaxies, which are characterised by different rates production (starbursts, SFGs, passive galaxies), those inside that made components (bulge, disk, halo). To investigate peculiar features found in our sample more depth, we focus here on their...
Context. Stellar bars are common morphological structures in the local Universe; according to optical and NIR surveys, they present about two-thirds of disc galaxies. These elongated also believed play a crucial role secular evolutionary processes, because able efficiently redistribute gas, stars, angular momentum within their hosts, although it remains unclear as whether enhance or suppress star formation. A useful tool investigate this ambiguity is main sequence (MS) relation, which...
