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 ...
Collective rotational bands at low excitation energy in 186Os: Vibrational and rotational degrees of freedom
(American Physical Society, 2022)
Collective structures in 186Os have been investigated through the 186W(4He, 4n) 186Os reaction, at a beam
energy of 48 MeV. The low-lying bands built on the excited 0+
2 , 2+
2 , and 4+
3 states have been extended up ...
