Little Red Dots: Rapidly Growing Black Holes Reddened by Extended Dusty Flows

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Zhengrong Li, Kohei Inayoshi, Kejian Chen, Kohei Ichikawa, Luis C. Ho | Summary: The James Webb Space Telescope (JWST) observations have revolutionized extragalactic research, particularly with the discovery of little red dots (LRD), which we propose are dust-reddened broad-line active galactic nuclei (AGNs). Their unique v-shape spectral […]

PKS 2131-021 — Discovery of Strong Coherent Sinusoidal Variations from Radio to Optical Frequencies: Compelling Evidence for a Blazar Supermassive Black Hole Binary

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Sebastian Kiehlmann, Philipe Vergara De La Parra, Andrew Sullivan, A. Synani, Ioannis Liodakis | Summary: Haystack and Owens Valley Radio Observatory (OVRO) observations recently revealed strong sinusoidal total flux density variations that maintained coherence between 1975 and 2021 in the blazar PKS 2131-021 ($z=1.283)$. This was interpreted […]

Rich and diverse molecular gas environments of closely-separated dual quasars viewed by ALMA

Kavli Affiliate: John D. Silverman | First 5 Authors: Shenli Tang, John D. Silverman, Zhaoxuan Liu, Manda Banerji, Tomoko Suzuki | Summary: We present a study of the molecular gas in five closely-spaced ($R_{perp}<20$ kpc) dual quasars ($L_{rm bol}gtrsim10^{44}~mathrm{erg~s}^{-1}$) at redshifts $0.4<z<0.8$ with the Atacama Large Millimeter/submillimeter Array. The dual quasar phase represents a distinctive […]

JADES — The Rosetta Stone of JWST-discovered AGN: deciphering the intriguing nature of early AGN

Kavli Affiliate: Roberto Maiolino | First 5 Authors: Ignas Juodžbalis, Xihan Ji, Roberto Maiolino, Francesco D’Eugenio, Jan Scholtz | Summary: JWST has discovered a large population of Active Galactic Nuclei (AGN) at high redshift. Many of these newly discovered AGN have broad permitted lines (typically H$alpha$), but are extremely weak in the X-rays. Here we […]
