Revisiting the [C ii]158𝝁��m line-intensity mapping power spectrum from the EoR using non-uniform line-luminosity scatter
(Oxford University Press, 2023)
Detecting the line-intensity mapping (LIM) signal from the galaxies of the Epoch of Reionization is an emerging tool to constrain
their role in reionization. Ongoing and upcoming experiments target the signal fluctuations ...
The MeerKAT pulsar timing array: First data release
(Oxford University Press, 2022)
We present the first 2.5 years of data from the MeerKAT Pulsar Timing Array (MPTA), part of MeerTime, a MeerKAT Large
Survey Project. The MPTA aims to precisely measure pulse arrival times from an ensemble of 88 pulsars ...
Interferometric H I intensity mapping: perturbation theory predictions and foreground removal effects
(Oxford University Press, 2023)
We provide perturbation theory predictions for the H I intensity mapping power spectrum multipoles using the Effective Field
Theory of Large Scale Structure, which should allow us to exploit mildly non-linear scales. ...
A search for variable subdwarf B stars in TESS Full Frame Images III. An update on variable targets in both ecliptic hemispheres – contamination analysis and new sdB pulsators
(Oxford University Press, 2023)
We present an update on the variable star survey performed on the TESS 30 min Full Frame
Image (FFI) data reported by our first two papers in this series. This update includes a
contamination analysis in order to identify ...
The LOFAR Tied-Array All-Sky Survey: Timing of 35 radio pulsars and an overview of the properties of the LOFAR pulsar discoveries
(Astronomy& Astrophysics, 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 pulsar ...
Galaxy and Mass Assembly (GAMA): Mid-infrared properties as tracers of galaxy environment
(EDP Sciences, 2023)
We investigate how different mid-infrared (mid-IR) properties of galaxies are correlated with the environment in which the
galaxies are located. For this purpose, we first study the dependence of galaxy clustering on the ...
Probing Cosmology beyond ΛCDM using the SKA
(Indian Academy of Sciences, 2023)
The cosmological principle states that the Universe is statistically homogeneous and isotropic at
large distance scales. Currently, there exist many observations which indicate a departure from this principle.
It has ...
Ceers key paper. I. An early look into the first 500myr of galaxy formation with jwst
(American Astronomical Society, 2023)
We present an investigation into the first 500 Myr of galaxy evolution from the Cosmic Evolution Early Release
Science (CEERS) survey. CEERS, one of 13 JWST ERS programs, targets galaxy formation from z ∼ 0.5 to >10
using ...
Direct optimal mapping for 21 cm cosmology: A demonstration with the hydrogen epoch of reionization array
(American Astronomical Society, 2022)
Motivated by the desire for wide-field images with well-defined statistical properties for 21 cm cosmology, we implement an optimal mapping pipeline that computes a maximum likelihood estimator
for the sky using the ...
Isoscalar giant monopole strength in 58Ni, 90Zr, 120Sn and 208Pb
(American Physical Society, 2023)
Inelastic α-particle scattering at energies of a few hundred MeV and very-forward
scattering angles including 0° has been established as a tool for the study of the isoscalar giant
monopole (IS0) strength distributions ...
