Multimodality and new materialism in science learning: Exploring insights from an introductory physics lesson
(Unisa Press, 2021)
Science disciplines are inherently multimodal, involving written and spoken language, bodily gestures, symbols, diagrams, sketches, simulation and mathematical formalism. Studies have shown that ...
Hi global scaling relations in the wise-whisp survey
(Oxford University Press, 2021)
We present the global scaling relations between the neutral atomic hydrogen gas, the stellar disk and the star forming
disk in a sample of 228 nearby galaxies that are both spatially and spectrally resolved in HI line ...
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) ...
Spectroscopic and electrochemical exploration of carbon-infused intercalation-type spinel composite for aqueous systems
(Frontiers Media, 2022)
Lithium-manganese-based compounds are promising intercalation host materials for
aqueous battery systems due to their synergy with high ionic conductive aqueous
electrolytes, safety, eco-friendliness, and low cost. Yet, ...
A new sample of southern radio galaxies: Host-galaxy masses and star-formation rates
(Oxford University Press, 2019)
In this study we define a new sample of distant powerful radio galaxies in order to study their host galaxy properties and provide targets for future observations of H I absorption with new radio telescopes and to understand ...
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 ...
Plausible explanation for the third COVID-19 wave in India and its implications
(KeAi Communications, 2023)
Recently some of us used a random-walk Monte Carlo simulation approach to study the spread of COVID-19. The calculations were reasonably successful in describing secondary and tertiary waves of infection, in countries such ...
Designing an optimal LSST deep drilling program for cosmology with type Ia supernovae
(American Astronomical Society, 2023)
The Vera C. Rubin Observatory’s Legacy Survey of Space and Time (LSST) is forecast to collect a large sample of
Type Ia supernovae (SNe Ia) expected to be instrumental in unveiling the nature of dark energy. The feat, ...
Short-period pulsating hot-subdwarf stars observed by TESS: I. Southern ecliptic hemisphere
(EDP Sciences, 2023)
We present results of a Transiting Exoplanet Survey Satellite (TESS) search for short-period pulsations in compact stellar objects
observed in years 1 and 3 of the TESS mission, during which the southern ecliptic hemisphere ...
