Unveiling the Nature of C/2023 A3 (Tsuchinshan-ATLAS): A Multi-Technique Observational Approach
Goldy Ahuja, Shashikiran Ganesh, Aravind Krishnakumar +3
Comet C/2023 A3 (Tsuchinshan-ATLAS) is a non-periodic dynamically new Oort cloud comet that was discovered independently by Purple Mountain Observatory in China and Asteroid Terres…
Broad-band temporal and spectral study of TeV blazar TXS 0518+211
Avik Kumar Das, Pankaj Kushwaha, Veeresh Singh +3
We present a long-term broad-band temporal and spectral study of a TeV BL Lac source TXS 0518+211 by analyzing nearly 16 years (MJD 54682 -- 60670) of simultaneous optical, UV and…
Effect of different Non-Gravitational accelerations on the trajectory of Interstellar Comet 3I/ATLAS
Goldy Ahuja, Shashikiran Ganesh
Comet C/2025 N1 or 3I/ATLAS is the third confirmed interstellar object. It has passed perihelion on 2025 October 29, and is currently on a path to leave the solar system. During it…
Wide-field Polarization Imaging and Numerical Modeling of the Coma and Tail of Comet C/2023 A3 (Tsuchinshan-ATLAS)
Mirza Arnaut, Christian Wöhler, Pritish Halder +3
Imaging polarimetry enables the spatially resolved investigation of cometary dust properties across different morphological structures. While cometary comae have been studied thoro…
Dynamical simulation of the Interstellar Comet 3I/ATLAS
Goldy Ahuja, Shashikiran Ganesh
Comet 3I/ATLAS, also known as C/2025 N1, was discovered on 2025 July 1 UT by NASA Asteroid Terrestrial-impact Last Alert System (ATLAS), with a v 58 kms. T…
Long-term monitoring of a dynamically new comet C/2020 V2 (ZTF)
Goldy Ahuja, K. Aravind, Shashikiran Ganesh +5
Comet C/2020 V2 (ZTF) is categorized as a dynamically new long-period comet, making its first approach to the inner Solar system. We have observed this comet for around 32 months (…
