Discovery of a near-infrared bar and a pseudobulge in the collisional ring galaxy Cartwheel

Barway, Sudhanshu; Mayya, Y. D; Robleto-Orus, Aitor (Oxford University Press on behalf of the Royal Astronomical Society, 2020-09)

We report the discovery of a bar, a pseudo-bulge, and unresolved point source in the archetype collisional ring galaxy Cartwheel using careful morphological analysis of a near-infrared (NIR) Ks-band image of excellent ...
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 ...
Unravelling the nuclear dust morphology of NGC 1365: a two-phase polar–RAT model for the ultraviolet to infrared spectral energy distribution

Swain, Subhashree; Shalima, P; Latha, K. V. P (Oxford University Press on behalf of Royal Astronomical Society, 2024-01)

We present a 3D radiative transfer model for the spectral energy distribution (SED) of NGC 1365, which is a ‘changing look’ Seyfert 1.8 type active galactic nucleus (AGN). The SED from the ultraviolet (UV) to the infrared ...
