Transient Quasi-Periodic Oscillations at -rays in the TeV Blazar PKS 1510-089
Abhradeep Roy, Arkadipta Sarkar, Anshu Chatterjee +3
We present periodicity search analyses on the -ray lightcurve of the TeV blazar PKS 1510-089 observed by the \textit{Fermi} Large Area Telescope. We report the detection of two…
Evaluation of the Constant Fraction Time-Over-Threshold (CF-TOT) method for neutron-gamma pulse shape discrimination
A. Roy, D. Vartsky, I. Mor +4
The use of Time-over-Threshold (TOT) for the discrimination between fast neutrons and gamma-rays is advantageous when large number of detection channels are required due to the sim…
Temporal and Spectral Study of PKS B1222+216 Flares in 2014
Anshu Chatterjee, Abhradeep Roy, Arkadipta Sarkar +1
We report on temporal and spectral study of a flat spectrum radio quasar, PKS B1222+216, in flare state to get insight into acceleration and emission mechanisms inside the jet. Thi…
Multiwavelength Study of the Quiescent States of Six Brightest Flat Spectrum Radio Quasars detected by Fermi-LAT
Abhradeep Roy, Sonal R. Patel, Arkadipta Sarkar +2
The regular monitoring of flat-spectrum radio quasars (FSRQs) in -rays by Fermi-LAT since past 12 years indicated six sources who exhibited extreme -ray outbursts crossing da…
Probing mild-tempered neutralino dark matter through top-squark production at the LHC
Monoranjan Guchait, Arnab Roy, Seema Sharma
The lightest neutralino, assumed to be the lightest supersymmetric particle, is proposed to be a dark matter (DM) candidate for the mass (100) GeV. Constraints from variou…
