A Cosmic Archipelago of lensed metal-poor galaxies at
A. Bolamperti, M. Messa, A. Zanella +21
The Cosmic Archipelago is an ensemble of galaxies, strongly lensed by the cluster MACSJ0416, showing extreme physical properties at . We combine JWST/NIRCam with deep VL…
First Statistical Study of Over 100 Magnified Stellar Events at Redshift with JWST
J. M. Palencia, Fengwu Sun, J. M. Diego +25
Highly magnified stars at cosmological distances () become detectable thanks to microlensing by intracluster stars near the critical curves of galaxy clusters. Multi…
Euclid: Scaled-up little red dots and other sources with v-shaped spectral energy distributions at z>4
Euclid Collaboration, A. A. Tumborang, K. I. Caputi +169
Little Red Dots (LRDs) are some the most intriguing galaxy populations recently identified at z>~4 with JWST. They constitute the most extreme class of a more abundant population o…
Constraining the geometry of the gas surrounding a typical galaxy at with Ly polarization
A. Bolamperti, S. -J. Chang, J. Vernet +6
Ly emission is the strongest tracer of recombining ionized hydrogen in young, star-forming galaxies, but its origin is still debated. Ly arises when emitted photons scatter…
