On twin peak quasi-periodic oscillations resulting from the interaction between discoseismic modes and turbulence in accretion discs around black holes
M. Ortega-Rodríguez, H. Solís-Sánchez, L. Álvarez-García +1
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 analy…
Deciding the status of controversial phonemes using frequency distributions; an application to semiconsonants in Spanish
Manuel Ortega-Rodríguez, Hugo Solís-Sánchez, Ricardo Gamboa-Alfaro
Exploiting the fact that natural languages are complex systems, the present exploratory article proposes a direct method based on frequency distributions that may be useful when ma…
The effects of anger on automated long-term-spectra based speaker-identification
Diana Valverde-Méndez, Manuel Ortega-Rodríguez, Hugo Solís-Sánchez +1
Forensic speaker identification has traditionally considered approaches based on long term spectra analysis as especially robust, given that they work well for short recordings, ar…
The Early Scientific Contributions of J. Robert Oppenheimer: Why Did the Scientific Community Miss the Black Hole Opportunity?
Manuel Ortega-Rodríguez, Hugo Solís-Sánchez, Eduardo Boza-Oviedo +5
We aim to carry out an assessment of the scientific value of Oppenheimer's research on black holes in order to determine and weigh possible factors to explain its neglect by the sc…
Global Disk Oscillation Modes in Cataclysmic Variables and Other Newtonian Accretors
Manuel Ortega-Rodriguez, Robert V. Wagoner
Diskoseismology, the theoretical study of small adiabatic hydrodynamical global perturbations of geometrically thin, optically thick accretion disks around black holes (and other c…
Relativistic Diskoseismology. III. Low-Frequency Fundamental p-Modes
Manuel Ortega-Rodriguez, Alexander S. Silbergleit, Robert V. Wagoner
We extend our investigation of the normal modes of small adiabatic oscillations of relativistic barotropic thin accretion disks to the inertial-pressure (p) modes. We focus here on…
Normal Modes of Black Hole Accretion Disks
Manuel Ortega-Rodriguez, Alexander S. Silbergleit, Robert V. Wagoner
This paper studies the hydrodynamical problem of normal modes of small adiabatic oscillations of relativistic barotropic thin accretion disks around black holes (and compact weakly…
'Stable' QPOs and Black Hole Properties from Diskoseismology
Robert V. Wagoner, Alexander S. Silbergleit, Manuel Ortega-Rodriguez
We compare our calculations of the frequencies of the fundamental g, c, and p--modes of relativistic thin accretion disks with recent observations of high frequency QPOs in X-ray b…
On the Perturbations of Viscous Rotating Newtonian Fluids
Manuel Ortega-Rodriguez, Robert V. Wagoner
The perturbations of weakly-viscous, barotropic, non-self-gravitating, Newtonian rotating fluids are analyzed via a single partial differential equation. The results are then used…
Proton-Proton Spin Correlations at Charm Threshold and Quarkonium Bound to Nuclei
Guy F. de Teramond, Randall Espinoza, Manuel Ortega-Rodriguez
The anomalous behavior of the spin-spin correlation at large momentum transfer in pp elastic scattering is described in terms of the degrees of freedom associated with the onset of…
