EDITORIAL NOTE

I am delighted to introduce a scientific journal being published by the Department of Physics, University of North Bengal, Journal of Physics Research and Education (JPRE), a new journal that emphasizes contribution in the emerging areas of research and education in Physics. JPRE provides a really exciting opportunity to consider the truly interdisciplinary nature of research in Physics at a time of great change across the wider landscape of Physics research. The objective of JPRE is to publish up-to-date, high-quality and original research papers alongside relevant and insightful reviews. The journal is also dedicated to maintaining and improving the standard of taught Physics in Universities and the submitted articles will be peer-reviewed. The journal aspires to be vibrant, engaging and accessible, and at the same time it should address the frontier, integrative and challenging issues in Physics. All articles must therefore contain contents that are physics research in interdisciplinary nature and applicable to the teaching of Physics at University level. Needless to say, any papers that you wish to submit, either individually or collaboratively, are much appreciated and will make a substantial contribution towards the advancement and success of the journal. Best wishes and thank you in advance for your contribution to the Journal of Physics Research and Education.

    TeV-PeV energy neutrinos and gamma rays from extragalactic milli-second pulsars
    (University of North Bengal, 2021-03) Dey, Rajat; Sarkar, Tamai
    The origin of the detected diffuse flux of extragalactic Pe V neutrinos during 2010 - 2017 by the Ice Cube Experiment is not clear and various models with sources were proposed for it. In the present work, we try to find theoretically whether pulsars could be one possible source. With our study, we found that the extragalactic millisecond pulsars which are newly born may be one possible source of Pe V neutrinos and gamma rays. For the purpose, we took two-step particle acceleration scheme for transferring the rotational energy to the electrons which are accelerated to high energy or boosted up to ~ 0.01 EeV energies or above. The high energy boosted electrons interacted with cold positrons and soft radiation in the acceleration zone might produce Ultra High Energy (UHE) neutrinos and gamma rays. The theoretically derived extragalactic muon neutrino energies are found consistent with the Ice Cube detection.
