Search for the origin of wobbling motion in the region: The case of Xe
S. Chakraborty, S. Bhattacharyya, R. Banik +24
In-beam -ray spectroscopy of Xe has been carried out to study the structure of the intruder band. Excited states were populated via an -induced fusion…
Probing the disc-jet coupling in S4 0954+65, PKS 0903-57, & 4C +01.02 with -rays
Ajay Sharma, Sushanth Reddy Kamaram, Raj Prince +2
We present a comprehensive variability study on three blazars, S4 0954+65, PKS 0903-57, and 4C +01.02 covering a mass range of log(M/M) = 8--9, by using 15 years-lo…
Finite-time Cosmological Singularities and the Possible Fate of the Universe
Jaume de Haro, Shin'ichi Nojiri, S. D. Odintsov +2
Singularities in any physical theory are either remarkable indicators of the unknown underlying fundamental theory, or indicate a change in the description of the physical reality.…
Equilibrium and Nonequilibrium phase transitions in continuous symmetric classical magnets
Olivia Mallick, Muktish Acharyya
The magnetism is an old problem of Physics. Most interesting part of the research on magnetism is its thermodynamic behaviour. In this review, the thermodynamic phase transitions,…
Quasi-periodic oscillation detected in -rays in blazar PKS 0346-27
Raj Prince, Anuvab Banerjee, Ajay Sharma +3
We present a variability study of the blazar PKS 0346-27 from December 2018 to January 2022 in its archival -ray observation by Fermi-LAT. We use the Lomb-Scargle periodogram an…
Correlated Short-Timescale Hard-Soft X-ray Variability of the Blazars Mrk 421 and 1ES 1959+650 using
Susmita Das, Ritaban Chatterjee
We study simultaneous soft ( keV) and hard ( keV) X-ray light curves at a total of eight epochs during of two TeV blazars Mrk 421 and 1ES 1959+650 ob…
