Ly Escape in JWST/NIRCam F430M-Selected H Emitters at
Cheng Cheng, Zhen-Ya Zheng, Chunyan Jiang +8
We study the Ly escape fraction () in an H-selected sample of star-forming galaxies at , identified via JWST/NIRCam F430M excess and covered by arc…
Diversity in Lyman Continuum Escape at Revealed by WISE Infrared Observations
Fang-Ting Yuan, Zhen-Ya Zheng, Chunyan Jiang +1
The escape of Lyman continuum (LyC) radiation from star-forming galaxies plays a key role in cosmic reionization. While strong LyC leakers are commonly identified through ultraviol…
Local Analogs of Little Red Dots: Optical Variability and Evidence for an Active Galatic Nucleus Origin
Ruqiu Lin, Zhen-Ya Zheng, Junxian Wang +9
Little red dots (LRDs) draw extensive attention because of their unique observational characteristics and apparent overabundance in the early Universe, raising new insights into ea…
LCEz4-M1: A Lyman Continuum Emitter Candidate at z = 4.444 in the MUSE Hubble Ultra Deep Field
Shuairu Zhu, Zhen-Ya Zheng, Fuyan Bian +5
High-redshift Lyman continuum emitters (LCEs) are crucial for understanding how galaxies ionize the neutral hydrogen in the epoch of reionization. However, detected LCEs at a…
Joint Analysis of Optical, Near-Infrared And Mid-Infrared Variability of 4 Quasars at Redshift < 1
Lin Long, Zhen-ya Zheng, Ning Jiang +8
Amid rapid advances in time-domain astronomy, multi-wavelength (e.g., optical and infrared) time-domain studies of quasars remain scarce. Here we present a systematic analysis of f…
Discovery of Local Analogs to JWST's Little Red Dots
Ruqiu Lin, Zhen-Ya Zheng, Chunyan Jiang +12
Recently, the James Webb Space Telescope (JWST) has revealed a new class of high redshift (high-, ) compact galaxies which are red in the rest-frame optical and blue in the…
