Cosmological constraints from the power spectrum and bispectrum of 21cm intensity maps
(IOP Publishing, 2022)
The 21cm emission of neutral hydrogen is a potential probe of the matter distribution in the Universe after reionisation. Cosmological surveys of this line intensity will be
conducted in the coming years by the SKAO and ...
Coulomb excitation of 102 Ru with 12 C and 16 O
(American Physical Society, 2022)
The Coulomb excitation of 102Ru was performed with beams of 12C and 16O ions. The beam particles
scattered at forward angles were momentum analyzed with a magnetic spectrograph. The resolution achieved
enabled the ...
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 ...
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 ...
Efficient long-range active galactic nuclei (agns) feedback affects the low-redshift lyα forest
(American Astronomical Society, 2023)
Active galactic nuclei (AGNs) feedback models are generally calibrated to reproduce galaxy observables such as
the stellar mass function and the bimodality in galaxy colors. We use variations of the AGN feedback
implementations ...
Constraining primordial non-gaussianity by combining next-generation galaxy and 21 cm intensity mapping surveys
(SpringerOpen, 2023)
Surveys of the matter distribution contain ‘fossil’
information on possible non-Gaussianity that is generated in
the primordialUniverse. This primordial signal survives only
on the largest scales where cosmic variance ...
On the time delay between ultra-relativistic particles
(Elsevier, 2016)
The time delay between the receptions of ultra-relativistic particles emitted simultaneously is a useful observable for both fundamental physics and cosmology. The expression of the delay when the particles travel through ...
