Dust in the very metal-poor galaxy Sextans A with JWST. I: Characterizing the evolved stellar population of Sextans A based on JWST observations and stellar evolution models
C. Gavetti, F. Dell'Agli, E. Tarantino +22
The nearby star-forming dwarf galaxy Sextans A offers a unique window into galaxy evolution in the early Universe, owing to its extremely low metallicity (about 1-7% Zsun). Recent…
Dust survival in harsh environments -- Is photo-evaporation an important destruction mechanism?
Ambra Nanni, Sergio Cristallo, Darko Donevski +3
Aims. We investigate the role of photo-evaporation of dust exposed to the radiation field from hot young stars and planetary nebulae (PNe) as a possible destruction mechanism of du…
z-GAL -- A NOEMA spectroscopic redshift survey of bright Herschel galaxies: [II] Dust properties
D. Ismail, A. Beelen, V. Buat +34
(Abridged) We present the dust properties of 125 bright Herschel galaxies selected from the z-GAL survey. The large instantaneous bandwidth of NOEMA provides an exquisite sampling…
z-GAL -- A NOEMA spectroscopic redshift survey of bright Herschel galaxies: [I] Overview
P. Cox, R. Neri, S. Berta +35
(Abridged) Using the IRAM NOEMA interferometer, we measures the redshifts of 126 bright galaxies detected in the Herschel H-ATLAS, HeLMS, and HerS surveys. We report reliable spect…
Metallicity-PAH Relation of MIR-selected Star-forming Galaxies in AKARI North Ecliptic Pole-wide Survey
Hyunjin Shim, Ho Seong Hwang, Woong-Seob Jeong +9
We investigate the variation in the mid-infrared spectral energy distributions of 373 low-redshift () star-forming galaxies, which reflects a variety of polycyclic aromatic…
The VMC Survey -- XLIX. Discovery of a population of quasars dominated by nuclear dust emission behind the Magellanic Clouds
Clara M. Pennock, Jacco Th. van Loon, Joy O. Anih +14
Following the discovery of SAGE0536AGN ( 0.14), with the strongest 10-m silicate emission ever observed for an Active Galactic Nucleus (AGN), we discovered SAGE0534AGN (…
