The critical radiation intensity for direct collapse black hole formation: dependence on the radiation spectral shape [PDF]
, 2014 It has been proposed that supermassive black holes (SMBHs) are originated from direct-collapse black holes (DCBHs) that are formed at z gtrsim 10 in the primordial gas in the case that H2 cooling is suppressed by strong external radiation.

Geophysical Monograph Series, Page 487-501., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Radiative decay of a massive particle and the non-thermal process in primordial nucleosynthesis [PDF]
, 2000 We consider the effects on big bang nucleosynthesis (BBN) of the radiative decay of a long-lived massive particle. If high-energy photons are emitted after the BBN epoch ($t \sim 1 - 10^3$ sec), they may change the abundances of the light elements ...

The Molecular Continuum Opacity of MgH in Cool Stellar Atmospheres [PDF]
Astrophys.J. 584 (2003) 459-464, 2002 The opacity due to photodissociation of 24MgH is investigated in the atmospheres of cool stars. The lowest two electronic transitions A 2Pi -- X 2Sigma+ and B' 2Sigma+ -- X 2 Sigma+ are considered where the cross sections for the latter were published previously (Weck, Stancil, & Kirby 2002) while the former are presented in this work.

Angewandte Chemie, EarlyView.A novel xanthate molecule was designed to facilitate highly controlled photoiniferter RAFT polymerization at fast rates under visible light. This approach was applied in aqueous photoinitiated polymerization‐induced self‐assembly (photo‐PISA). The rapid photolysis and extended absorption of this xanthate enable ultrafast and scalable fabrication of ...
