Cosmological Parallax--Distance Formula
Ashok K. Singal
The standard cosmological parallax--distance formula, as found in the literature, including text-books and reference books on cosmology, requires a correction. This correction stem…
Determining planetary positions in the sky for years to an accuracy of with a calculator}
Tanmay Singal, Ashok k. Singal
In this paper, we describe a very simple method to calculate the positions of the planets in the sky. The technique used enables us to calculate planetary positions to an accuracy…
Maximum Brightness Temperature of an Incoherent Synchrotron Source : Inverse Compton Limit - a Misnomer
Ashok K. Singal
We show that an upper limit of ~ 10^{12} K on the peak brightness temperature for an incoherent synchrotron radio source, commonly referred to in the literature as an inverse Compt…
Maximum brightness temperature for an incoherent synchrotron radio source
Ashok K. Singal
We discuss here a limit on the maximum brightness temperature achievable for an incoherent synchrotron radio source. This limit, commonly referred to in the literature as an invers…
