From a report based on an independent investigation by a senior fellow of the Indian Academy of Sciences, we find that there is evidence of academic misconduct in the paper titled, ‘‘Numerical simulation of inertial alfvenwaves to study localized structures and spectral index in auroral region’’ by Bheem Singh Jatav (https://doi.org/10.1007/s12036-018-9531-8; volume 39 article ID 37) published in Journal of Astrophysics and Astronomy. Therefore, the Indian Academy of Sciences has decided to withdraw the publication, on the grounds of academic misconduct by the author. The author has been notified and has agreed to the retraction.
Volume 39 Issue 3 June 2018 Article ID 0037 RETRACTED ARTICLE
In the present paper, the numerical simulation of Inertial Alfven wave (IAW) in low-$\beta$ plasma applicable to the auroral region at 1700 km was studied. It leads to the formation of localized structures when the nonlinearity arises due to ponderomotive effect and Joule heating. The effect of perturbation and magnitude of pump IAW, formed the localized structures of magnetic field, has been studied. The formed localized structures at different times and average spectral index scaling of power spectrum have been observed. Resultsobtained from simulation reveal that spectrum steepens with power law index $\sim −$3.5 for shorter wavelength. These localized structures could be a source of particle acceleration and heating by pump IAW in low-$\beta$ plasma.

Continuous Article Publishing mode
Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
