Evaluating Impact of Social Media Posts by Executives on Stock Prices
Anubhav Sarkar, Swagata Chakraborty, Sohom Ghosh +1
Predicting stock market movements has always been of great interest to investors and an active area of research. Research has proven that popularity of products is highly influence…
The Indian Pulsar Timing Array: First data release
Pratik Tarafdar, Nobleson K., Prerna Rana +35
We present the pulse arrival times and high-precision dispersion measure estimates for 14 millisecond pulsars observed simultaneously in the 300-500 MHz and 1260-1460 MHz frequency…
On the propagation of gravitational waves in matter-filled Bianchi I universe
Sucheta Datta, Sarbari Guha, Samarjit Chakraborty
In this paper we apply the Regge-Wheeler formalism to study the propagation of axial and polar gravitational waves in matter-filled Bianchi I universe. Assuming that the expansion…
KM3NeT upper bounds of detection rates of solar neutrinos from annihilations of dark matter at the solar core
Aman Gupta, Debasish Majumdar, Ashadul Halder
The Weakly Interacting Massive Particles (WIMPs) so far remain one of the most popular candidates for dark matter. If captured gravitationally inside the core of the Sun, these WIM…
Heating of the intracluster medium by buoyant bubbles and sound waves
Asif Iqbal, Subhabrata Majumdar, Biman B. Nath +1
Active galactic nuclei (AGN) powered by the central Super-Massive Black Holes (SMBHs) play a major role in modifying the thermal properties of the intracluster medium (ICM). In thi…
Constraining PBH mass distributions from 21cm brightness temperature results and an analytical mapping between probability distribution of 21cm signal and PBH masses
Upala Mukhopadhyay, Debasish Majumdar, Ashadul Halder
The evaporation of Primordial Black Hole (PBH) via Hawking radiation influences the evolution of Inter Galactic Medium by heating up the latter and consequently affects the 21cm si…
