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 ...
Quijote-png: Quasi-maximum likelihood estimation of primordial non-gaussianity in the nonlinear dark matter density field
(American Astronomical Society, 2022)
Future large-scale structure surveys are expected to improve current bounds on primordial non-Gaussianity (PNG),
with a significant impact on our understanding of early universe physics. The level of such improvements ...
Impact of Rubin observatory cadence choices on supernovae photometric classification
(American Astronomical Society, 2023)
The Vera C. Rubin Observatory’s Legacy Survey of Space and Time (LSST) will discover an unprecedented
number of supernovae (SNe), making spectroscopic classification for all the events infeasible. LSST will thus rely
on ...
Multifilter time-series observations of eleven blue short-period atlas variable stars
(IOP Publishing, 2023)
Eleven periodic variable stars were observed photometrically through two to four filters from the set UBVRCIC.
Phase-folded data for each star cover full cycles of variation. Spectral energy distributions, based on ...
