Probing the central engine and environment of AGN using ARIES 1.3-m and 3.6-m telescopes

Chand, H; Rakshit, S; Jalan, P; Ojha, V; Srianand, R; Vivek, M; Mishra, S; Omar, A; Kumar, P; Joshi, R; Gopal Krishna; Kumar, R (Societe Royale des Sciences de Liege, 2018-04)

: We discuss three long term observational programmes to probe the central engine and environment of active galactic nuclei (AGN) using the recently installed ARIES 1.3-m and 3.6-m telescopes. The first programme is on ...

Kumar, R; Pradhan, A. C; Mohapatra, Abhisek; Moharana, Ayush; Ojha, D. K; Parthasarathy, M; Murthy, J (Oxford University Press on behalf of the Royal Astronomical Society, 2021-03)

We present detailed photometric observations of the Galactic globular cluster NGC 7492 using the data obtained with two far-ultraviolet (FUV; 1300–1800 Å) and three near-ultraviolet (NUV; 2000–3000 Å) filters of Ultraviolet ...
UVIT observations of UV-Bright stars in four Galactic Globular Clusters

Kumar, R; Pradhan, A. C; Parthasarathy, M; Ojha, D. K; Mohapatra, A; Murthy, J (Cambridge University Press, 2019-05)

We have performed photometric analysis of four Galactic globular clusters (GGCs): NGC 4147, NGC 4590, NGC 5053 and NGC 7492 using far-UV and near-UV filters of the Ultraviolet Imaging Telescope (UVIT) on-board AstroSat. ...
