Continuing influence of shell effects at high-excitation energies
(Elsevier, 2019)
Empirical drops in ground-state nuclear polarizabilities indicate deviations from the effect of giant dipole
resonances and may reveal the presence of shell effects in semi-magic nuclei with neutron magic
numbers N = 50, ...
Disentangling non-gaussianity, bias, and general relativistic effects in the galaxy distribution
(American Physical Society, 2012)
Local non-Gaussianity, parametrized by
f
NL
, introduces a scale-dependent bias that is strongest at large scales, precisely where general relativistic (GR) effects also become significant. With future data, it should ...
Reconstruction of dark energy and expansion dynamics using Gaussian processes
(IOP Publishing, 2012)
An important issue in cosmology is reconstructing the effective dark energy equation
of state directly from observations. With few physically motivated models, future dark
energy studies cannot only be based on constraining ...
Nonlinear galactic dynamos and the magnetic pitch angle
(American Astronomical Society, 2015)
Pitch angles p of the large-scale magnetic fields B of spiral galaxies have previously been inferred from
observations to be systematically larger in magnitude than predicted by standard mean-field dynamo theory. ...
Intrinsic scatter of caustic masses and hydrostatic bias: An observational study
(EDP Sciences, 2017)
All estimates of cluster mass have some intrinsic scatter and perhaps some bias with true mass even in the absence of measurement
errors for example caused by cluster triaxiality and large scale structure. Knowledge of ...
