X-rays breaking out of pre-explosion ejecta mark a supernova's first light
Weimin Yuan, Qiu-Ju Huang, Jin-Ping Zhu +130
Massive stars die as core-collapse supernovae, whose optical light emerges days after the implosion. Theory predicts that the initial collapse-driven shock, upon breaking through t…
Early metal-enriched baryon cycling before the midpoint of cosmic reionization
Yongda Zhu, Zhiyuan Ji, George D. Becker +13
Models predict that chemical enrichment and gas redistribution should begin rapidly once star formation starts, but direct constraints at the earliest epochs have been scarce. Here…
High-Resolution ALMA Imaging for a Gravitationally-lensed Quasar at : Constraining the AGN Contribution to Galactic-Scale Dust Heating
Minghao Yue, Xiaohui Fan, Anna-Christina Eilers +6
We present high-resolution (beam size $0\farcs076\times0\farcs040$) Atacama Large Millimeter/submillimeter Array (ALMA) observations of the far-infrared $(λ_\text{rest}=162.7μ\rm…
Extreme Galaxy-scale Outflows Are Frequent among Luminous Early Quasars
Weizhe Liu, Xiaohui Fan, Huan Li +23
The existence of abundant post-starburst/quiescent galaxies just 1-2 Gyrs after the Big Bang challenges our current paradigm of galaxy evolution. Cosmological simulations sug…
A Potential Link between Nuclear Winds and Cold Gas Outflows on Kiloparsec Scales in Reionization-Era Quasars
Yongda Zhu, Marcia J. Rieke, Luis C. Ho +23
Feedback from accreting supermassive black holes may regulate galaxy evolution, but statistical evidence linking nuclear winds to kiloparsec-scale cold gas outflows remains limited…
The Cosmic Owl: Twin Active Collisional Ring Galaxies with Starburst Merging Front at
Mingyu Li, Bjorn H. C. Emonts, Zheng Cai +12
Galaxy mergers play a critical role in driving galaxy evolution, especially by transforming galaxy morphology, redistributing gas around galaxies, triggering active galactic nuclei…
