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 ...
Quijote-png: Simulations of primordial non-gaussianity and the information content of the matter field power spectrum and bispectrum
(IOP Publishing, 2023)
Primordial non-Gaussianity (PNG) is one of the most powerful probes of the early universe, and measurements of
the large-scale structure of the universe have the potential to transform our understanding of this area. ...
Quijote-png: The information content of the halo power spectrum and bispectrum
(IOP Publishing, 2023)
We investigate how much can be learnt about four types of primordial non-Gaussianity (PNG) from small-scale
measurements of the halo field. Using the QUIJOTE-PNG simulations, we quantify the information content
accessible ...
Continuing influence of shell effects at high-excitation energies
(Elsevier, 2019)
Empirical drops in ground-state nuclear polarizabilities indicate deviations from the effect of giant dipole
resonances and may reveal the presence of shell effects in semi-magic nuclei with neutron magic
numbers N = 50, ...
Semi-analytic forecasts for Roman – the beginning of a new era of deep-wide galaxy surveys
(Oxford University Press, 2023)
The Nancy Grace Roman Space Telescope, NASA’s next flagship observatory, will redefine deep-field galaxy survey with a field of view two orders of magnitude larger than
Hubble and an angular resolution of matching quality. ...
H I intensity mapping with MeerKAT: Power spectrum detection in cross-correlation with WiggleZ galaxies
(Oxford University Press, 2023)
We present a detection of correlated clustering between MeerKAT radio intensity maps and galaxies from the WiggleZ Dark Energy Survey. We find a 7.7σ detection of the cross-correlation power spectrum, the amplitude of which ...
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 ...
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 physical nature of circumgalactic medium absorbers in SIMBA
(Oxford University Press, 2023)
We study the nature of the low-redshift circumgalactic medium (CGM) in the SIMBA cosmological simulations as traced by
ultraviolet absorption lines around galaxies in bins of stellar mass (M > 1010M) for star-forming, ...
