JADES: Nitrogen Enhancement in High-Redshift Broad-Line Active Galactic Nuclei

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Yuki Isobe, Roberto Maiolino, Francesco D’Eugenio, Mirko Curti, Xihan Ji | Summary: The unexpectedly high nitrogen-to-oxygen (N/O) ratios observed in high-redshift (z) galaxies have challenged our understanding of early star formation. Notably, many of these nitrogen-rich galaxies show signatures of active galactic nuclei (AGNs), suggesting a possible […]

Using Infrared Dust Echoes to Identify Bright Quasi-periodic Eruption Sources

Kavli Affiliate: Dheeraj R. Pasham | First 5 Authors: Dheeraj R. Pasham, Eric Coughlin, Sjoert van Velzen, Jason Hinkle, | Summary: Quasi-periodic eruptions (QPEs) are recurring soft X-ray outbursts from galactic nuclei and represent an intriguing new class of transients. Currently, 10 QPE sources are reported in the literature, and a major challenge lies in […]
