Broadly my research work would be based on the “Multi-wavelength study of Active galactic
Nuclei(AGN)”. This year I have mainly focused on a class of AGN called Narrow line Seyfert 1
(NLSy1) galaxy. The sample consist of well selected 18 NLSy1 galaxies, which are at least detected
in X-ray at more than 3σ level. The aim to choose X-ray bright NLSy1 is to explore the origin of
X-ray emission since generally Seyfert galaxies are less prominent in high energy band. The other
motivation was the recent surprising discovery of gamma-ray emission from dozen of NLSy1 galaxies, which has been associated to the presence of jets in their center, generally found in elliptical
radio galaxies/rather than in spiral galaxies. So one possibility is that may be the cause of X-ray
emission in X-ray detected NLSy1 galaxies might also be associated to the mild jet activity in their
center, as proposed gamma-ray detected NLSy1 galaxies. Higher duty cycle of Intra-night optical
variability is one of the diagnostic commonly used to quantify significant jet activity where even
small fluctuation in flux can get Doppler boosted. Therefore we have used the ARIES 1.3m DFOT
telescope for the INOV study of our sample. As of now about 16 sources have been monitored each
lasting for more than 3.5 hours. The data has been analyzed and paper is almost in final stage.
Out of the total 16 session we have not found any source which show variability after applying
robust statistical tests. This suggests the absence of jet dominance as for as X-ray emission is
concerned, though our source being faint the improvement required higher sensitivity using 2m
class telescopes. Our group is also involved in making the catalog of NLSy1 galaxy based on large
data-set of 1.5 million AGN from SDSS-DR12, which I plan to use to prepare a sub-sample for
their multi-wavelength study especially with ARIES 3.6m DOT for optical and astro-sat for X-rays
for detail study in my thesis. In addition, I was also a part of photometric reverberation campaign
carried on 15 night from 1.3m telescope. My involvement was assisting the observation and then
reduction of the data in two broad and one narrow band, which has been also completed. This
program is to characterize the L-R relation of broad line region of low luminosity AGN.
