NEXUS: Discovery of a Luminous Young Transient at
Ming-Yang Zhuang, Yue Shen, Lei Hu +8
We report the discovery of AT 2026abck, a young transient in a star-forming galaxy at , identified from Year-2 observations of the NEXUS JWST treasury program. AT…
Surveying the Universe in 4D: Beating Cosmic Variance with Wide-Field Slitless Spectroscopy from HST, JWST, Euclid, Roman, and Beyond
Andreea Petric, Gaël Noirot, Stacey Alberts +71
We summarize strategies, lessons learned, and future directions from the Space Telescope Science Institute workshop Surveying the Universe in 4D: Beating Cosmic Variance with Wide-…
NEXUS: Transient Searches and First Results from Year One Observations
Ming-Yang Zhuang, Lei Hu, Justin D. R. Pierel +10
We describe ongoing efforts of high-redshift transient searches using multi-epoch NIRCam imaging (F200W+F444W) and NIRSpec MSA/PRISM spectroscopy from the NEXUS JWST multi-cycle Tr…
Luminosity function of quasars at from SDSS and DESI
Gaocheng Yin, Linhua Jiang, Zhiwei Pan +54
We present a study of the evolution of type 1 quasars at , covering the peak epoch of quasar activity. The quasar evolution has been extensively explored by a variety of…
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…
Changing-Look AGNs from DESI. VI. Host Galaxies
Shengxiu Sun, Linhua Jiang, Wei-Jian Guo +2
Changing-look (CL) AGNs trace rapid changes in nuclear activity, but their connection to host galaxy properties remains unclear. We present a study of the host galaxies of 105 CL A…
Quiescent Host Galaxies of Extended Quasars Revealed by Spectrophotometric Decomposition
Shengxiu Sun, Linhua Jiang, Zhiwei Pan +27
Previous works of low-redshift quasar host galaxies have focused on compact quasars and found that their host galaxies are mainly star-forming galaxies. Here we present a study of…
Stacked Reverberation Mapping of High Redshift Quasars in DESI. I. Feasibility Analysis
Rahma Alfarsy, R. E. A. Canning, Eva-Maria Mueller +49
The broad line region of quasars has long been probed by reverberation mapping techniques that measure time lags between continuum and broad emission line variations. Stacked rever…
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…
DeepDISC-Euclid: Source Classification and Photometric Redshifts in Euclid Deep Field North With a Pixel-Level Deep Learning Approach
Yuanzhe Jiang, Yue Shen, Grant Merz +8
The first Euclid Quick Data Release (Q1) provides extensive imaging and spectroscopic data for hundreds of millions of photometric objects across several deep fields. Accurate clas…
COSMOS-3D: Black Hole Mass Estimators and Luminosity Functions of Paschen-line AGNs
Danyang Jiang, Linhua Jiang, Shuqi Fu +13
Near-IR Paschen lines are potentially an excellent tracer of Type 1 AGNs that is hardly affected by dust extinction. JWST allows us, for the first time, to explore Paschen-line obj…
