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…

Strong Lensing Model and Dust Extinction Maps of the Host Galaxy of Type Ia Supernova H0pe

A. Galan, S. Schuldt, G. B. Caminha +11

Strong gravitational lensing by massive galaxy clusters offers rare opportunities to observe multiple images of distant () Type Ia supernovae (SNe) and to resolve the…

JWST spectroscopic confirmation of the Cosmic Gems arc at z=9.625 -- Insights into the small scale structure of a post-burst system

M. Messa, E. Vanzella, F. Loiacono +30

We present JWST/NIRSpec integral field spectroscopy of the Cosmic Gems arc, strongly magnified by the galaxy cluster SPT-CL J06155746. Six-hour integration using NIRSpec prism s…

Positive neutrino masses with DESI DR2 via matter conversion to dark energy

S. Ahlen, A. Aviles, B. Cartwright +46

The Dark Energy Spectroscopic Instrument (DESI) is a massively parallel spectroscopic survey on the Mayall telescope at Kitt Peak, which has released measurements of baryon acousti…

Extending the cosmic distance ladder two orders of magnitude with strongly lensed Cepheids, carbon AGB, and RGB stars

J. M. Diego, S. P. Willner, J. M. Palencia +1

Gravitational lensing by galaxy clusters can create extreme magnification near the cluster caustics, thereby enabling detection of individual luminous stars in high-redshift backgr…

Extreme Ionizing Properties of Metal-Poor, Muv ~ -12 Star Complex in the first Gyr

E. Vanzella, F. Loiacono, M. Messa +38

We report the serendipitous discovery of a faint (M_UV > -12.2), low-metallicity (Z ~ 0.02 Zsun), ionizing source (dubbed T2c) with a spectroscopic redshift of z=6.146. T2c is part…
