SN 2017hcc and SN 2023usc a comparative spectroscopic study of type IIn supernovae
Sethulakshmi Vazhayil, Firoza K. Sutaria, Riddhiman Sharma +1
We report on a spectroscopic study of the bright, nearby type-IIn supernova SN 2017hcc, and SN 2023usc using data obtained from the Himalayan Chandra Telescope (HCT). SN 2017hcc is…
Astrophysics with Compact Objects: An Indian Perspective, Present Status and Future Vision
Manjari Bagchi, Prasanta Bera, Aru Beri +18
Astrophysical compact objects, viz., white dwarfs, neutron stars, and black holes, are the remnants of stellar deaths at the end of their life cycles. They are ideal testbeds for v…
Comet C/2012 S1 (ISON) crossing the Jupiter orbit
Margarita Safonova, Noah Brosch, Shai Kaspi +4
We report results of intensive time-resolved imaging photometry and synoptic deep imaging of the comet C/2012 S1 (ISON) performed in February 2013. The data were obtained at the Wi…
Deep Photometry of Suspected Gravitational Lensing Events: Potential Detection of a Cosmic String
Margarita Safonova, Igor I. Bulygin, Olga S. Sazhina +3
Cosmic strings (CS) are one-dimensional cosmological-size objects predicted in realistic models of the early Universe. Analysis of the cosmic microwave background (CMB) anisotropy…
Simultaneous X-ray/UV observations of ultraluminous X-ray source Holmberg II X-1 with Indian space mission AstroSat
A. Vinokurov, K. Atapin, O. P. Bordoloi +11
We present the results of 8 epochs of simultaneous UV and X-ray observations of the highly variable ultraluminous X-ray source (ULX) Holmberg II X-1 with AstroSat -- Indian multiwa…
Planetary Nebulae with UVIT: A Progress Report
N. Kameswara Rao, Sutaria F., Murthy J. +2
The spectral region between 1250 Angstroms - 3000 Angstroms contains important spectral lines to understand the morphological structures and evolution of planetary nebulae. This is…
