Annually it has two peak periods, where February and July being the winter and summer components, respectively. The CLLJ is an important ... -
On twin peak quasi-periodic oscillations resulting from the interaction between discoseismic modes and turbulence in accretion discs around black holes
(2020)Given the peculiar and (in spite of many efforts) unexplained quasi-periodic oscillation (QPO) twin peak phenomena in accretion disc psd observations, the present exploratory analytical article tries to inquire deeper ... -
