Transient QPOs of Fermi-LAT blazars under the Curved Jet Model

P. Penil, J. Otero-Santos, A. Banerjee +4

This study explores transient quasi-periodic oscillations (QPOs) in the -ray emission of two blazars, PMN J05314827 and PKS 1502+106, using over a decade of Fermi Large Area…

Extension of the particle x-ray coincidence technique: The lifetimes and branching ratios apparatus

L. J. Sun, J. Dopfer, A. Adams +11

The particle x-ray coincidence technique (PXCT) was originally developed to measure average lifetimes in the ~s range for proton-unbound states populated by elec…

On the energy of Hořava-Lifshitz black holes

I. Radinschi, F. Rahaman, A. Banerjee

In this paper we calculate the energy distribution of the Mu-in Park, Kehagias-Sfetsos (KS) and Lü, Mei and Pope (LMP) black holes in the Hořava-Lifshitz theory of gravity. These…

Observation of different spin behavior with temperature variation and Cr substitution in a multiferroic compound YMnO

K. Mukherjee, Kranti Kumar, A. Banerjee

In this article, the collective response of the spins is explored through low field bulk magnetic measurement for the series YMnCrO (x= 0.0, 0.05). Low field ac sus…

Conversion of glassy antiferromagnetic-insulating phase to equilibrium ferromagnetic-metallic phase by devitrification and recrystallization in Al substituted PrCaMnO

A. Banerjee, Kranti Kumar, P. Chaddah

We show that PrCaMnO with 2.5% Al substitution and LaCaMnO (LCMO) exhibit qualitatively similar and visibly anomalous M-H curves at…

Bianchi II, VIII, and IX viscous fluid cosmology

A. Banerjee, Abhik Kumar Sanyal, S. Chakraborty

In this paper we study the exact solutions for a viscous fluid distribution in Bianchi II, VIII, and IX models. The metric is simplified by assuming a relationship between the coef…
