The importance of determining the sidereal rotation period of an astronomical object on future investigations pertaining to said object has been well documented in the literature. Researchers, howe...

In certain pulsar timing experiments, where observations are scheduled approximately periodically (e.g. daily), timing models with significantly different frequencies (including but not limited to glitch models with different frequency increments) re

Satellite equivalence orbits are orbits coupling two or more relative satellite motions. Equivalence orbits between tropical and meridional motion are direct orbits. They have exactly the period 2 sidereal days. As consequence of Kepler's third law t

Our objective in this paper is to assess all errors in NavIC's pseudorange so that they can be mitigated or accounted for appropriately in the dynamics model to achieve high-accuracy navigation. Multipath errors in the L5 and S1 pseudoranges are diff

The dark photon is a massive hypothetical particle that interacts with the Standard Model by kinetically mixing with the visible photon. For small values of the mixing parameter, dark photons can evade cosmological bounds to be a viable dark matter c

Total power radiometry with individual meter-wave antennas is a potentially effective means to detect the brightness temperature from the 21 cm line of neutral hydrogen during the Cosmic Dawn. In the process, spectra of integrated sky brightness temp

Analyses of neutrino measurements acquired by the Super-Kamiokande Neutrino Observatory (SK, in operation 1996–2001) and radon decay measurements acquired by the Geological Survey of Israel (GSI, in operation 2007–2017) yield strikingly similar d
