An autonomous approach to model daytime behavior of sub-ionospheric VLF signals over short and medium propagation paths in India
Sayak Chakraborty, Tamal Basak, Sourav Palit +1
We present an autonomous model to simulate the daytime variation of sub-ionospheric Very Low Frequency (VLF) signal amplitude, beginning with the computation of the D-region electr…
Modeling of the variability of D-region ionospheric electron density during solar cycle-24
Sayak Chakraborty, Sourav Palit, Semontee Deb +1
Solar cycle variation of earth's atmosphere, particularly the ionosphere is of particular interest in the field of space science and space weather studies. In this article, we pres…
On the altitude profile of lower ionospheric D-region response time delay during solar flares
Sayak Chakraborty, Rakhi Paul, Tamal Basak
The D-region ionosphere is sluggish in nature while responding to the incoming solar radiation. We study the altitude (h) profile of mid-latitude D-region response time delay (Delt…
A Simple Method of Demonstration of Characteristics of Rainbows Using a Glass of Water and a Few Laser Sources
Soumen Sarkar, Sanjoy Kumar Pal, Pradipta Panchadhyayee +2
A rainbow is a captivating natural phenomenon resulting from the refraction, dispersion, and reflection of sunlight within water droplets. Traditional classroom demonstrations ofte…
Study of the effect of electromagnetic damping force on a magnet oscillating near a non-ferromagnetic conducting plate
Sanjoy Kumar Pal, Soumen Sarkar, Pradipta Panchadhyayee +1
We have designed an experiment that involves studying the effects of a conducting plate on the motion of an oscillating disc magnet. We have employed the video analysis method by T…
A New Catalog of Head Tail Radio Galaxies from the VLA FIRST Survey
Tapan K. Sasmal, Soumen Bera, Sabyasachi Pal +1
The head--tail (HT) morphology of radio galaxies is seen for a class of radio sources where the primary lobes are being bent in the intercluster weather due to strong interactions…
