Detection of Gravitational Anomaly at Low Acceleration from a Highest-quality Sample of 36 Wide Binaries with Accurate 3D Velocities
K. -H. Chae, B. -C. Lee, X. Hernandez +4
We set out to accurately measure gravity in the low-acceleration range from 3D motions of isolated wide binary stars. Gaia DR3 provides…
Elastic overtones: an equal temperament 12 tone music system with "perfect" fifths
X. Hernandez, Luis Nasser, Pablo Garcia-Valenzuela
The impossibility of a transposable 12 semitone tuning of the octave arises from the mathematical fact that i.e., the second harmonic of the fifth can no…
Dynamical Friction Constraints on the Dark Matter Hypothesis Across Astronomical Scales
X. Hernandez, Pavel Kroupa
Dynamical friction implies a consistency check on any system where dark matter particles are hypothesised to explain orbital dynamics requiring more mass under Newtonian gravity th…
Thermodynamics of harmony: extending the analogy across musical systems
L. Nasser, A. Tillotson, X. Hernandez
It is common for most people to think of science and art as disparate, or at most only vaguely related fields. In physics, one of the biggest successes of thermodynamics is its exp…
A recent confirmation of the wide binary gravitational anomaly
X. Hernandez, Pavel Kroupa
Concerning recent published studies exploring the presence or otherwise of a gravitational anomaly at low accelerations in wide binary stars as observed by the {\it Gaia} satellite…
A critical review of recent GAIA wide binary gravity tests
X. Hernandez, Kyu-Hyun Chae, A. Aguayo-Ortiz
Over the last couple of years, the appearance of the third data release from the {\it Gaia} satellite has triggered various wide binary low acceleration gravity tests. Wide binarie…
Statistical analysis of the gravitational anomaly in {\it Gaia} wide binaries
X. Hernandez, V. Verteletskyi, L. Nasser +1
The exploration of the low acceleration regime, where m s is the acceleration scale of MOND around which gravitational anomalies at gala…
On the Existence of the Plateau Emission in High-Energy Gamma-Ray Burst LightCurves observed byFermi-LAT
Maria Giovanna Dainotti, Nicola Omodei, Gokul . P. Srinivasaragavan +10
The Large Area Telescope (LAT) on board the \Fermi Gamma-ray Space Telescope (\Fermi) shows long-lasting high-energy emission in many gamma-ray bursts (GRBs), similar to X-ray afte…
A Test of MONDian Gravity in 300 pressure supported elliptical galaxies from the MaNGA survey
R. Durazo, X. Hernandez, B. Cervantes Sodi +1
Pressure supported systems modeled under MONDian extended gravity are expected to show an outer flattening in their velocity dispersion profiles. A characteristic scaling between t…
Dynamical friction in dwarf galaxies
X. Hernandez, Gerard Gilmore
We present a simplified analytic approach to the problem of the spiraling of a massive body orbiting within the dark halo of a dwarf galaxy. This dark halo is treated as the core r…
