Galaxy Spectra Networks (GaSNet). III. Generative pre-trained network for spectrum reconstruction, redshift estimate and anomaly detection
Fucheng Zhong, Nicola R. Napolitano, Caroline Heneka +11
Classification of spectra (1) and anomaly detection (2) are fundamental steps to guarantee the highest accuracy in redshift measurements (3) in modern all-sky spectroscopic surveys…
Investigating chemical variations between interstellar gas clouds in the Solar neighbourhood
T. Ramburuth-Hurt, A. De Cia, J. -K. Krogager +6
The interstellar medium (ISM) is a fundamental component of the Milky Way. Studying its chemical composition and the level of its chemical diversity gives us insight into the evolu…
Modelling of long gamma-ray burst host galaxies at cosmic noon from damped Lyman-α absorption statistics
J. -K. Krogager, A. De Cia, K. E. Heintz +11
We study the properties of long gamma-ray burst (GRB) host galaxies using a statistical modelling framework derived to model damped Lyman- absorbers (DLAs) in quasar spectra at…
Transverse clues on the kpc-scale structure of the circumgalactic medium as traced by C IV absorption
S. Lopez, A. Afruni, D. Zamora +13
We present VLT/MUSE integral-field spectroscopy () of four giant gravitational arcs exhibiting strong C IV absorption at 8 intervening redshifts, $z_{abs}\approx 2…
DUNE: Dust depletion UNified method across cosmic time and Environments
Christina Konstantopoulou, Annalisa De Cia, Jens-Kristian Krogager +5
We present a novel method to characterize dust depletion, namely, the depletion of metals into dust grains. We used observed correlations among relative abundances combining a tota…
The α-element enrichment of gas in distant galaxies
Anna Velichko, Annalisa De Cia, Christina Konstantopoulou +3
The chemical evolution of distant galaxies cannot be assessed from observations of individual stars, in contrast to the case of nearby galaxies. On the other hand, the study of the…
