Mid-infrared variability of γ-ray emitting blazars

Anjum, A; Stalin, C. S; Rakshit, S; Gudennavar, S. B; Durgapal, A (Oxford University Press on behalf of the Royal Astronomical Society, 2020-05)

Using data from the Wide-field Infrared Survey Explorer, we studied the mid-infrared (mid-IR) 3.4 μm (W1-band) and 4.6 μm (W2-band) flux variability of γ-ray emitting blazars. Our sample consists of 460 flat spectrum radio ...
The peculiar radio-loud narrow line seyfert 1 galaxy 1H 0323+342

Paliya, Vaidehi S; Sahayanathan, S; Parker, M. L; Fabian, A. C; Stalin, C. S; Anjum, A; Pandey, S. B (IOP Publishing, 2014-07-10)

We present a multi-wavelength study of the radio-loud narrow line Seyfert 1 galaxy (NLSy1), 1H 0323+342, detected by Fermi Gamma Ray Space Telescope. Multi-band light curves show many orphan X-ray and optical flares having ...
Template-based classification of SDSS-GALEX point sources

Anjum, A; Mousumi Das; Murthy, J; Gudennavar, S. B; Rajesh, G; Bubbly, S. G (Indian Academy of Sciences, 2018-10)

We have classified a sample of 37,492 objects from SDSS into QSOs, galaxies and stars using photometric data over five wave bands (u, g, r, i and z) and UV GALEX data over two wave bands (near-UV and far-UV) based on a ...
