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 ...
Periodic low-frequency electric field structures in a magnetized non-thermal auroral plasma
(Elsevier, 2019)
The theoretical explanation of electric field structures associated with density depletion in the Earth’s upper
ionosphere is presented. Using the quasi-neutrality hypothesis, the effect of excess energetic electron ...
Automorphism groups of graph covers and uniform subset graphs
(Taylor and Francis Group, 2018)
Hofmeister considered the automorphism groups of antipodal graphs through the exploration of graph covers. In this note weextend the exploration of automorphism groups of distance preserving graph covers. We apply the ...
Quadrupole and octupole collectivity in the semi-magic nucleus 80206Hg126
(Elsevier, 2023)
The first low-energy Coulomb-excitation measurement of the radioactive, semi-magic, two proton-hole nucleus 206Hg, was performed at CERN's recently-commissioned HIE-ISOLDE facility. Two γ rays depopulating low-lying states ...
The lofar tied-array all-sky survey: Timing of 35 radio pulsars and an overview of the properties of the lofar pulsar discoveries
(EDP Sciences, 2023)
The LOFAR Tied-Array All-Sky Survey (LOTAAS) is the most sensitive untargeted radio pulsar survey performed at low radio
frequencies (119−151 MHz) to date and has discovered 76 new radio pulsars, including the 23.5-s ...
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 ...
The orbital periods of aa dor and ny vir
(Oxford University Press, 2011)
New timings of eclipses made between 2000 and 2010 are presented for two binary systems
with hot subdwarf primary stars. In the case of AA Dor, an sdOB star with a very cool
secondary, the period is found to be constant ...
Identifying multiple periodicities in sparse photon event time series
(Oxford University Press, 2016)
The data considered are event times (e.g. photon arrival times, or the occurrence of sharp
pulses). The source is multiperiodic, or the data could be multiperiodic because several unresolved sources contribute to the time ...
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, ...
