Context:In 2020 May-June, six solar energetic ion events were observed by the Parker Solar Probe/ISoIS instrument suite at 0.35 AU from the Sun. From standard velocity-dispersion a…
Spectroscopic long-term monitoring of RZ Cas -- Part I: Basic stellar and system parameters
H. Lehmann, A. Dervisoglu, D. E. Mkrtichian +3
RZ Cas is a short-period Algol-type system showing episodes of mass transfer and Delta Sct-like oscillations of its mass-gaining primary component. We analyse high-resolution spect…
Evolution of the truncated disc and inner hot-flow of GX 339-4
P. Chainakun, W. Luangtip, A. J. Young +2
Aims. We study the changes in geometry of the truncated disc and the inner hot-flow of GX 339-4 by analyzing the Power SpectralDensity (PSD) extracted from six XMM-Newton observati…
Series solution of the time-dependent Schrödinger-Newton equations in the presence of dark energy via the Adomian Decomposition Method
Tiberiu Harko, Man Kwong Mak, Matthew J. Lake
The Schrödinger-Newton model is a nonlinear system obtained by coupling the linear Schrödinger equation of canonical quantum mechanics with the Poisson equation of Newtonian mechan…
Calibration Strategy of the JUNO Experiment
JUNO collaboration, Angel Abusleme, Thomas Adam +588
We present the calibration strategy for the 20 kton liquid scintillator central detector of the Jiangmen Underground Neutrino Observatory (JUNO). By utilizing a comprehensive multi…
