NEXUS: Spectral Variability of Little Red Dots and Blue Active Galactic Nuclei at
Zachary Stone, Yue Shen, Ming-Yang Zhuang +4
We present spectral measurements for 17 Little Red Dots (LRDs) and 14 blue broad-line active galactic nuclei (AGNs) at using multi-epoch JWST NIRSpec MSA s…
NEXUS: Abundance, Environments, and Spectral Diversity of Little Red Dots from the NIRSpec MSA Sample
Zhiwei Pan, Ming-Yang Zhuang, Yue Shen +6
We present a comprehensive study of Little Red Dots (LRDs) at 2.3 < z < 7.4 using NIRCam photometry and NIRSpec MSA/PRISM spectra from the ongoing NEXUS program. Photometric select…
NEXUS: Quick Release Notes
Ming-Yang Zhuang, Yue Shen, Junyao Li +6
NEXUS is a JWST Multi-Cycle (Cycles 3-5) GO Treasury imaging and spectroscopic survey around the North Ecliptic Pole during 2024-2028. It contains two overlapping tiers in depth an…
Merger-driven buildup of the - relation bridging high- overmassive black holes with the local relation
Takumi S. Tanaka, John D. Silverman, Kazuhiro Shimasaku +3
The origin of the mass scaling relation between supermassive black holes (SMBHs, ) and galaxies () remains a key open question. Rather than invoking AGN feedback,…
Hidden in Pixels I: Discovery of dual "little red dots" indicates excess clustering on kilo-parsec scales
Takumi S. Tanaka, John D. Silverman, Kazuhiro Shimasaku +56
``Little Red Dots'' (LRDs) are an abundant high-redshift population newly discovered by the James Webb Space Telescope (JWST) and considered to be an early growth phase of supermas…
Photometric Redshifts in JWST Deep Fields: A Pixel-Based Alternative with DeepDISC
Grant Merz, Ming-Yang Zhuang, Junyao Li +4
Photo-z algorithms that utilize SED template fitting have matured, and are widely adopted for use on high-redshift near-infrared data that provides a unique window into the early u…
