Ultralarge-scale approximations and galaxy clustering: Debiasing constraints on cosmological parameters
(Oxford University Press, 2022)
Upcoming galaxy surveys will allow us to probe the growth of the cosmic large-scale structure with improved sensitivity
compared to current missions, and will also map larger areas of the sky. This means that in addition ...
Antenna beam characterization for the global 21-cm experiment LEDA and its impact on signal model parameter reconstruction
(Oxford University Press, 2022)
Cosmic dawn, the onset of star formation in the early universe, can in principle be studied via the 21-cm transition of neutral hydrogen, for which a sky-averaged absorption signal, redshifted to MHz frequencies, is predicted ...
Constraining the neutrino mass using a multitracer combination of two galaxy surveys and cosmic microwave background lensing
(Oxford University Press, 2022)
Measuring the total neutrino mass is one of the most exciting opportunities available with next-generation cosmological data
sets. We study the possibility of detecting the total neutrino mass using large-scale clustering ...
Gaussian process regression for foreground removal in hi intensity mapping experiments
(Oxford University Press, 2022)
We apply for the first time Gaussian Process Regression (GPR) as a foreground removal technique in the context of single-dish, low redshift H I intensity mapping, and present an open-source PYTHON toolkit for doing so. We ...
Probabilistic learning for pulsar classification
(IOP Publishing, 2022)
In this work, we explore the possibility of using probabilistic learning to identify
pulsar candidates. We make use of Deep Gaussian Process (DGP) and Deep Kernel Learning
(DKL). Trained on a balanced training set in ...
Hiflow: Generating diverse hi maps and inferring cosmology while marginalizing over astrophysics using normalizing flows
(IOP Publishing, 2022)
A wealth of cosmological and astrophysical information is expected from many ongoing and upcoming large-scale
surveys. It is crucial to prepare for these surveys now and develop tools that can efficiently extract ...
On the primordial origin of the smoothing excess in the Planck temperature power spectrum in light of LSS data
(IOP Publishing, 2022)
The Planck DR3 measurements of the temperature and polarization anisotropies power spectra of the cosmic microwave background (CMB) show an excess of smoothing of the acoustic peaks with respect to ΛCDM, often quantified ...
Measurements of one-point statistics in 21-cm intensity maps via foreground avoidance strategy
(Oxford University Press, 2022)
Measurements of the one-point probability distribution function and higher-order moments (variance, skewness, and kurtosis) of
the high-redshift 21-cm fluctuations are among the most directstatistical probes of the ...
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 ...
