What can we learn from the Nitrogen abundance of High-z galaxies?

Massimo Stiavelli, Takahiro Morishita, Marco Chiaberge +9

We present measurements of the gas-phase Oxygen and Nitrogen abundances obtained by applying the direct method to JWST NIRspec spectroscopy for 6 galaxies at redshift g…

Accelerated Emergence of Evolved Galaxies in Early Overdensities at

Takahiro Morishita, Zhaoran Liu, Massimo Stiavelli +8

We report the identification of two galaxy overdensities at in the sightline of the galaxy cluster Abell 2744. These overdensities consist of 25 and 17 member galaxies,…

Improved model of the Supernova Refsdal cluster MACS J1149.5+2223 thanks to VLT/MUSE

S. Schuldt, C. Grillo, G. B. Caminha +9

We present new VLT/MUSE observations of the Hubble Frontier Field (HFF) galaxy cluster MACS J1149.5+2223, lensing the well-known supernova "Refsdal" into multiple images, which ena…
