Angewandte Chemie, Volume 132, Issue 30, Page 12545-12549, July 20, 2020., 2020 There they are! Phenylphosphinidene oxide and phenylphosphinidene sulphide can readily be prepared through photoinduced fragmentation of their corresponding phosphonic diazide precursors. They were identified using IR and UV/Vis spectroscopies in combination with computational methods.

Frontiers in Astronomy and Space Sciences, 2017 The reionization of helium at z ~ 3 is the final phase transition of the intergalactic medium and supposed to be driven purely by quasars. The He ii transverse proximity effect—enhanced He ii transmission in a background sightline caused by the ionizing ...

Patchy Kinetic Sunyaev–Zel’dovich Effect with Controlled Reionization History and Morphology
The Astrophysical Journal, 2023 Using the novel semi-numerical code for reionization AMBER, we model the patchy kinetic Sunyaev–Zel’dovich (kSZ) effect by directly specifying the reionization history with the redshift midpoint z _mid , duration Δ _z , and asymmetry A _z .

Simulating the Cosmic Dawn With Enzo
Frontiers in Astronomy and Space Sciences, 2018 We review two decades of progress using the Enzo hydrodynamic cosmology code to simulate the Cosmic Dawn, a period of roughly 1 billion years beginning with the formation of the first stars in the universe, and ending with cosmic reionization.

HST UV Spectroscopy of the Dwarf Starburst Galaxy Pox 186
The Astrophysical Journal, 2023 Studying the galaxies responsible for reionization is often conducted through local reionization-era analogs; however, many of these local analogs are too massive to be representative of the low-mass star-forming galaxies that are thought to play a ...

Cosmic Reionization on Computers: Properties of the Post-reionization IGM [PDF]
The Astrophysical Journal, 2017 Abstract We present a comparison between several observational tests of the post-reionization intergalactic medium and the numerical simulations of reionization completed under the Cosmic Reionization On Computers (CROC) project. The CROC simulations match the gap distribution reasonably well, and also provide a good match for the ...

The Kinetic Sunyaev-Zel'dovich effect as a probe of the physics of cosmic reionization: the effect of self-regulated reionization [PDF]
, 2013 We calculate the angular power spectrum of the Cosmic Microwave Background (CMB) temperature fluctuations induced by the kinetic Sunyaev-Zel'dovich (kSZ) effect from the epoch of reionization (EOR).

Cosmological reionization [PDF]
AIP Conference Proceedings, 2001 The universe was reionized by redshift z ~ 6 by a small fraction of the baryons in the universe, which released energy following their condensation out of a cold, dark, and neutral IGM into the earliest galaxies. The theory of this reionization is a critical missing link in the theory of galaxy formation.

The Universe is at Most 88% Neutral at z = 10.6
The Astrophysical Journal Letters, 2023 Recent observations of GN-z11 with JWST have revealed a Ly α emission line with an equivalent width (EW) of 18 ± 2 Å. At z = 10.6, this galaxy is expected to lie in the heart of reionization.
