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 ...
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 ...
An∼600 pc View of the Strongly Lensed, Massive Main-sequence Galaxy J0901: A Baryon-dominated, Thick Turbulent Rotating Disk with a Clumpy Cold Gas Ring at z=2.259
(Institute of Physics, 2023)
We present a high-resolution kinematic study of the massive main-sequence star-forming galaxy (SFG)
SDSS J090122.37+181432.3 (J0901) at z = 2.259, using ∼0 36 Atacama Large Millimeter/submillimeter Array
CO(3–2) and ∼0 ...
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 ...
Multifilter observations of the complex periodic variations in eight pre-main sequence stars
(Royal Astronomical Society, 2023)
Follow up time series photometry through various combinations of the BVRCIC filter set is presented for eight young stars. The complex periodic variability of seven of the stars was first discovered in TESS photometry, ...
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. ...
