High-precision half-life determination of 14O via direct β counting
(Springer, 2022)
The half-life of the superallowed Fermi β+ emitter 14O was determined to high precision via a direct
β counting experiment performed at the Isotope Separator and Accelerator (ISAC) facility at TRIUMF. The result,
T1/2(
14O) ...
Gravitational signal propagation in the double pulsar studied with the MeerKAT telescope
(Hans Publishers, 2022)
The double pulsar PSR J0737−3039A/B has offered a wealth of gravitational experiments in the strong-field regime, all of which
general relativity has passed with flying colours. In particular, among current gravity ...
Measurements of one-point statistics in 21-cm intensity maps via foreground avoidance strategy
(Oxford University Press, 2022)
Measurements of the one-point probability distribution function and higher-order moments (variance, skewness, and kurtosis) of
the high-redshift 21-cm fluctuations are among the most directstatistical probes of the ...
Cosmological constraints from the power spectrum and bispectrum of 21cm intensity maps
(IOP Publishing, 2022)
The 21cm emission of neutral hydrogen is a potential probe of the matter distribution in the Universe after reionisation. Cosmological surveys of this line intensity will be
conducted in the coming years by the SKAO and ...
Coulomb excitation of 102 Ru with 12 C and 16 O
(American Physical Society, 2022)
The Coulomb excitation of 102Ru was performed with beams of 12C and 16O ions. The beam particles
scattered at forward angles were momentum analyzed with a magnetic spectrograph. The resolution achieved
enabled the ...
How open data and interdisciplinary collaboration improve our understanding of space weather: A risk and resiliency perspective
(Frontiers Media, 2022)
Space weather refers to conditions around a star, like our Sun, and its
interplanetary space that may affect space- and ground-based assets as well
as human life. Space weather can manifest as many different phenomena,
often ...
Unveiling the universe with emerging cosmological probes
(Springer, 2022)
The detection of the accelerated expansion of the Universe has been one of the major breakthroughs in modern cosmology. Several cosmological probes (Cosmic Microwave Background, Supernovae Type Ia, Baryon Acoustic Oscillations) ...
The MeerKAT pulsar timing array: First data release
(Oxford University Press, 2022)
We present the first 2.5 years of data from the MeerKAT Pulsar Timing Array (MPTA), part of MeerTime, a MeerKAT Large
Survey Project. The MPTA aims to precisely measure pulse arrival times from an ensemble of 88 pulsars ...
Direct optimal mapping for 21 cm cosmology: A demonstration with the hydrogen epoch of reionization array
(American Astronomical Society, 2022)
Motivated by the desire for wide-field images with well-defined statistical properties for 21 cm cosmology, we implement an optimal mapping pipeline that computes a maximum likelihood estimator
for the sky using the ...
Quijote-png: Quasi-maximum likelihood estimation of primordial non-gaussianity in the nonlinear dark matter density field
(American Astronomical Society, 2022)
Future large-scale structure surveys are expected to improve current bounds on primordial non-Gaussianity (PNG),
with a significant impact on our understanding of early universe physics. The level of such improvements ...
