Architecture Design and Ground Performance of Netherlands‐China Low‐Frequency Explorer

Radio Science, Volume 59, Issue 8, August 2024.
Abstract The Netherlands‐China Low‐Frequency Explorer (NCLE) (Boonstra et al., 2017, https://www.ursi.org/proceedings/procGA17/papers/Paper_J19‐2(1603).pdf; Chen et al., 2020, https://ui.adsabs.harvard.edu/abs/2020AAS…23610203C/abstract) is a radio instrument for astrophysical studies in the low‐frequency range (80 kHz–80 MHz).

The Epoch of Reionization [PDF]

, 2012
The Universe's dark ages end with the formation of the first generation of galaxies. These objects start emitting ultraviolet radiation that carves out ionized regions around them. After a sufficient number of ionizing sources have formed, the ionized fraction of the gas in the Universe rapidly increases until hydrogen becomes fully ionized.

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 temperature fluctuations induced by the kinetic Sunyaev-Zel'dovich (kSZ) effect from the epoch of reionization (EOR). We use detailed N-body+radiative-transfer simulations to

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

Angewandte 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

The Kinetic Sunyaev‐Zel’dovich Effect from Reionization

, 2019
During the epoch of reionization, local variations in the ionized fraction ( patchiness) imprint arcminute- scale temperature anisotropies in the CMB through the kinetic Sunyaev- Zel'dovich ( kSZ) effect.

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

Advanced 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.

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

Molecular 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.

Is Double Reionization Physically Plausible?

, 2019
Recent observations of z similar to 6 quasars and the cosmic microwave background imply a complex history of cosmic reionization. Such a history requires some form of feedback to extend reionization over a long time interval, but the nature of the ...
