Measuring lensing ratios with future cosmological surveys
(American Physical Society, 2020)
The ratio between the CMB lensing/galaxy counts and the galaxy shear/galaxy counts cross-correlations combines the information from different cosmological probes to infer cosmographic measurements that are less dependent ...
Torsion driven inflationary magnetogenesis
(American Physical Society, 2020)
We show that the breaking of the conformal invariance of the electromagnetic Lagrangian, which is required for inflationary magnetogenesis, arises naturally in the Poincaré gauge theory. We use the minimal coupling ...
Global analysis of the COVID-19 pandemic using simple epidemiological models
(Elsevier, 2021)
Several analytical models have been developed in this work to describe the evolution of fatalities arising from coronavirus COVID-19 worldwide. The Death or ‘D’ model is a simplified version of the well-known SIR ...
Biomass Energy Dependence in South Africa: Are the Western Cape Province households descending the energy ladder after improvement in electricity access?
(Elsevier, 2020)
South Africa was considered to have attained universal access to modern energy from 1994 to 2012. This meant that the number of households that moved away from the use of dirty energy to ...
Predicting coronary artery disease risk in firefighters – a cross-sectional study
(2021-07-30)
Background: Firefighters are placed under severe cardiovascular load in performing active duty and, when carrying various coronary artery disease (CAD) risk factors, firefighters are predisposed to significant morbidity ...
The 2020 release of the ExoMol database: Molecular line lists for exoplanet and other hot atmospheres
(Elsevier, 2020)
The ExoMol database (www.exomol.com) provides molecular data for spectroscopic studies of hot atmospheres. While the data are intended for studies of exoplanets and other astronomical bodies, the dataset is widely applicable. ...
NOEMA redshift measurements of bright Herschel galaxies
(EDP Sciences, 2020)
Using the IRAM NOrthern Extended Millimeter Array (NOEMA), we conducted a program to measure redshifts for 13 bright galaxies detected in the Herschel Astrophysical Large Area Survey with S500 μm ≥ 80 mJy. We report reliable ...
The evolution of the low-frequency radio AGN population to z 1.5 in the ELAIS N1 field
(Advance Access publication, 2020-11-13)
We study the cosmic evolution of radio sources out to z 1.5 using a GMRT 610 MHz survey covering ∼1.86 deg2 of the ELAIS
N1 field with a minimum/median rms noise 7.1/19.5 μJy beam−1 and an angular resolution of 6 arcsec. ...
Significance levels of common frequencies extracted from multiple data sets
(Oxford University Press, 2020)
Large monitoring campaigns, particularly those using multiple filters, have produced replicated time series of observations for literally millions of stars. The search for periodicities in such replicated data can be ...
