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…

The case for super-Eddington accretion in JWST broad-line AGN during the first billion years

Erini Lambrides, Rebecca Larson, Kristen Garofali +23

A multitude of JWST studies reveal a surprising over-abundance of over-massive accreting super-massive black holes (SMBHs) -- leading to a deepening tension between theory and obse…

Unveiling the Cosmic Gems Arc at with JWST NIRCam

Larry D. Bradley, Angela Adamo, Eros Vanzella +22

We present recent JWST NIRCam imaging observations of SPT0615-JD (also known as the Cosmic Gems Arc), lensed by the galaxy cluster SPT-CL J0615-5746. The 5 arcsec long arc is the m…
