The Messy Nature of Fiber Spectra: Star–Quasar Pairs Masquerading as Dual Type 1 AGNs

Ryan W. Pfeifle, Barry Rothberg, Kimberly A. Weaver, Remington O. Sexton et al. • The Astrophysical Journal (2023)

Theoretical studies predict that the most significant growth of supermassive black holes (SMBHs) occurs in late-stage mergers, coinciding with the manifestation of dual active galactic nuclei (AGNs), and both major and minor mergers are exp...

Multiwavelength Study of Five Distant Transient Gamma-Ray AGNs with z > 1

Hai-Qin Wang, Fang-Kun Peng, Rui Xue, Lu-Ming Sun • The Astrophysical Journal (2024)

The multiwavelength emissions, especially gamma-rays, of active galactic nuclei (AGNs) are essential for studying the physical properties of jets emanating from supermassive black holes at galaxy centers. However, for high-redshift AGNs, it...

Seeding Cores: A Pathway for Nuclear Star Clusters from Bound Star Clusters in the First Billion Years

Fred Angelo Batan Garcia, Massimo Ricotti, Kazuyuki Sugimura • The Open Journal of Astrophysics (2025)

We model the formation of star clusters in a dwarf galaxy progenitor during the first 700 Myr of cosmic history using a cosmological radiation-hydrodynamic simulation with a sub-grid star formation efficiency (SFE) model calibrated from AU-...
