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…
