Inferring halo masses with graph neural networks
(Institute of Physics, 2022)
Understanding the halo–galaxy connection is fundamental in order to improve our knowledge on the nature and
properties of dark matter. In this work, we build a model that infers the mass of a halo given the positions,
...
A comparison of multi-phase magnetic field tracers in a high-galactic latitude region of the filamentary interstellar medium
(IOP Publishing, 2022)
Understanding how the Galactic magnetic field threads the multiphase interstellar medium (ISM) remains a
considerable challenge, as different magnetic field tracers probe dissimilar phases and field components. We search
for ...
Mightee-hi: Evolution of hi scaling relations of star-forming galaxies at z < 0.5*
(IOP Publishing, 2022)
We present the first measurements of H I galaxy scaling relations from a blind survey at z > 0.15. We perform
spectral stacking of 9023 spectra of star-forming galaxies undetected in H I at 0.23 < z < 0.49, extracted ...
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 ...
Exomol line lists – xliv. Infrared and ultraviolet line list for silicon monoxide (28si16o)
(Oxford University Press, 2022)
A new silicon monoxide (
28Si16O) line list covering infrared, visible, and ultraviolet regions called SiOUVenIR is presented.
This line list extends the infrared EBJT ExoMol line list by including vibronic transitions ...
A structure function analysis of vst-cosmos agn
(EDP Sciences, 2022)
We present our sixth work in a series dedicated to variability studies of active galactic nuclei (AGN), based on the survey of the COSMOS field by the VLT Survey Telescope (VST). Its 54 r-band visits over 3.3 yr and ...
Development of a 127Xe calibration source for nEXO
(IOP Publishing, 2022)
We study a possible calibration technique for the nEXO experiment using a 127Xe electron capture source. nEXO is a next-generation search for neutrinoless double beta decay (0νββ) that will use a 5-tonne, monolithic liquid ...
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 ...
