Tracing Lyman alpha escape in the CRISTAL-02 galaxy at z~5.3
Arshi Ali, Lucia Guaita, Manuel Aravena +20
We investigate the mechanisms regulating Lyman-alpha (Ly) escape in the star-forming galaxy CRISTAL-02 at z~5.3. The galaxy has clumpy morphology, suggestive that it may be inte…

Unsupervised selection and characterisation of Little Red Dots in JWST surveys with manifold learning
Michele Ginolfi, Filippo Mannucci, Alessandro Marconi +9
Little Red Dots (LRDs) are compact, red sources discovered at high redshift by JWST whose physical nature and selection function remain debated. We investigate whether an unsupervi…

One cloud is not enough: extreme conditions bias chemical abundances in high-redshift galaxies
Bianca Moreschini, Francesco Belfiore, Alessandro Marconi +18
Since its launch, JWST has opened an unprecedented opportunity to characterise the ionised ISM of high-redshift galaxies using well-established rest-frame UV/optical diagnostics fr…
