Gas‐Phase Formation of Sulfurous Acid (H2SO3) in the Atmosphere

open access: yesAngewandte Chemie International Edition, Volume 63, Issue 30, July 22, 2024.
Laboratory experiments show the formation of sulfurous acid (H2SO3) from the gas‐phase reaction of OH radicals with CH3S(O)OH for atmospheric reaction conditions with a molar yield of ∼50 %. H2SO3 represents a hard‐to‐reach acid that has never been observed in aqueous solution. In the gas phase, if once formed, it shows a certain kinetic stability with

A SPectroscopic Survey of Biased Halos In the Reionization Era (ASPIRE): JWST Supports Earlier Reionization around [O iii] Emitters

open access: yesThe Astrophysical Journal
Understanding when and how reionization happened is crucial for studying the early structure formation and the properties of the first galaxies in the Universe. At z > 5.5, the observed intergalactic medium (IGM) optical depth shows a significant scatter,

Optical Evidence of Compositional Fractioning between Plasma‐Condensed and Melt Pool Matter

open access: yesAdvanced Engineering Materials, Volume 26, Issue 13, July 2024.
This work presents an initial look at correlating the optical emissions of the weld plasma to that of the composition of particles condesned from the plasma plume. Particles removed from the melt pool through the plasma plume have atomic percent level differences in composition of alloy elements when compared to the originating metal.

Forecasts for Helium Reionization Detection with Fast Radio Bursts in the Era of Square Kilometre Array

open access: yesThe Astrophysical Journal
The observed dispersion measures (DMs) of fast radio bursts (FRBs) are a good indicator of the amount of ionized material along the propagation paths.

Reionization and Beyond: detecting the peaks of the cosmological 21cm signal [PDF]

open access: yes, 2014
[ABRIDGED] The cosmological 21cm signal is set to become the most powerful probe of the early Universe, with first generation interferometers aiming to make statistical detections of reionization. There is increasing interest also in the pre-reionization

Dependence of the Local Reionization History on Halo Mass and Environment: Did Virgo Reionize the Local Group? [PDF]

open access: yes, 2007
The reionization of the Universe has profound effects on the way galaxies form and on their observed properties at later times. Of particular importance is the relative timing of the reionization history of a region and its halo assembly history, which can affect the nature of the first stars formed in that region, the properties and radial ...

Updating and profiling the natural product‐likeness of Latin American compound libraries**

open access: yesMolecular Informatics, Volume 43, Issue 7, July 2024.
We discuss a comparative and extensive profiling of the natural product‐likeness of an updated version of LANaPDB and the individual ten compound databases that form part of LANaPDB. The profiling is conducted with three different chemoinformatics metrics.

A SPectroscopic Survey of Biased Halos in the Reionization Era (ASPIRE): JWST Reveals a Filamentary Structure around a z = 6.61 Quasar

open access: yesThe Astrophysical Journal Letters, 2023
We present the first results from the JWST program A SPectroscopic survey of biased halos In the Reionization Era (ASPIRE). This program represents an imaging and spectroscopic survey of 25 reionization-era quasars and their environments by utilizing the
