The impact of solar wind variability on pulsar timing
(EDP Sciences, 2021)
Context. High-precision pulsar timing requires accurate corrections for dispersive delays of radio waves, parametrized by the dispersion measure (DM), particularly if these delays are variable in time. In a previous paper, ...

Observing relativistic features in large-scale structure surveys - I. Multipoles of the power spectrum
(Oxford University Press, 2021)
Planned efforts to probe the largest observable distance scales in future cosmological surveys are motivated by a desire to detect relic correlations left over from inflation and the possibility of constraining novel ...
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 ...
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 ...
A New Model For Including Galactic Winds in Simulations of Galaxy Formation II: Implementation of PhEW in Cosmological Simulations
(Monthly Notices of the Royal Astronomical Society, 2021)
Although galactic winds play a critical role in regulating galaxy formation, hydrodynamic cosmological simulations
do not resolve the scales that govern the interaction between winds and the ambient circumgalactic medium ...
An orientation bias in observations of submillimetre galaxies
(Monthly Notices of the Royal Astronomical Society, 2021)
Recent high-resolution interferometric images of submillimetre galaxies (SMGs) reveal fascinatingly complex morphologies.
This raises a number of questions: how does the relative orientation of a galaxy affect its observed ...
Chemical Vapor Deposited Mixed Metal Halide Perovskite Thin Films
(Materials, 2021)
In this article, we used a two-step chemical vapor deposition (CVD) method to synthesize methylammonium lead-tin triiodide perovskite films, MAPb1−xSnxI3, with x varying from 0 to 1. We successfully controlled the concentration ...
HI intensity mapping with the MIGHTEE survey: power spectrum estimates
(Monthly Notices of the Royal Astronomical Society, 2021)
Intensity mapping (IM) with neutral hydrogen is a promising avenue to probe the large scale structure of the Universe. In this paper, we demonstrate that using the 64-dish MeerKAT radio telescope as a connected interferometer, ...
The evolution of the low-frequency radio AGN population to z 1.5 in the ELAIS N1 field
(Oxford University Press, 2021)
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. ...
