A catalogue of 108 extended planetary nebulae observed by GALEX

Pradhan, Ananta C; Panda, Swayamtrupta; Parthasarathy, M; Murthy, J; Ojha, Devendra K (Springer, 2019-10)

We present the ultraviolet (UV) imaging observation of planetary nebulae (PNe) using archival data of Galaxy Evolution Explorer (GALEX). We found 358 PNe detected by GALEX in near-UV (NUV). We have compiled a catalogue of ...
Globular Cluster UVIT Legacy Survey (GlobULeS) – II. Evolutionary status of hot stars in M3 and M13

Kumar, Ranjan; Pradhan, Ananta C; Sahu, Snehalata; Subramaniam, A; Piridi, Sonika; Cassisi, Santi; Ojha, Devendra K (Oxford University Press on behalf of Royal Astronomical Society, 2023-06)

We present a far-ultraviolet (FUV) study of hot stellar populations in the second parameter pair globular clusters (GCs) M3 and M13, as a part of the GC UVIT Legacy Survey programme (GlobULeS). We use observations made ...
Study of UV bright sources in globular cluster NGC 4590 using Ultraviolet Imaging Telescope (UVIT) observations

Kumar, Ranjan; Pradhan, Ananta C; Parthasarathy, M; Piridi, Sonika; Cassisi, Santi; Ojha, Devendra K; Mohapatra, Abhisek; Murthy, J (Oxford University Press on behalf of Royal Astronomical Society, 2022-04)

We have studied ultraviolet (UV) bright sources in the Galactic globular cluster (GGC) NGC 4590 using Ultraviolet Imaging Telescope onboard the AstroSat satellite. Using UV-optical colour–magnitude diagrams (CMDs), we ...
