  • Long-term monitoring of a dynamically new comet C/2020 V2 (ZTF) 
    Ahuja, Goldy; Aravind, K; Ganesh, S; Hmiddouch, Said; Donckt, Mathieu Vander; Jehin, E; Sahu, D. K; Sivarani, T (Oxford University Press on behalf of Royal Astronomical Society, 2025-10)
    Comet C/2020 V2 (ZTF, Zwicky Transient Facility) 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 (from 2022 January ...
  • Polycyclic Aromatic Hydrocarbons in the circumstellar medium of Herbig Ae/Be stars 
    Arun, R; Mathew, Blesson; Shridharan, B; Ujjwal, K; Akhil, Krishna R; Maheswar, G; Kartha, Sreeja S (IOP Publishing, 2025-09)
    We present a comprehensive mid-infrared spectroscopic survey of 124 Herbig Ae/Be stars using newly processed Spitzer/IRS spectra from the newly released CASSISjuice database. Based on prominent dust and molecular signatures ...
  • Inflationary magnetogenesis beyond slow-roll and its induced gravitational waves 
    Atkins, Bill; Chowdhury, Debika; Marriott-Best, Alisha; Tasinato, Gianmassimo (American Physical Society, 2025-09-15)
    The origin of magnetic fields observed on both astrophysical and cosmological scales is a compelling problem that has the potential to shed light on the early Universe. We analytically investigate inflationary magnetogenesis ...
  • Predicting CME speed at 20R⊙ using machine learning approaches 
    Hegde, M (Springer Nature, 2025-09)
    Coronal mass ejections (CMEs) are significant drivers of space weather, and accurately predicting their propagation speed is crucial for mitigating their impact on Earth’s environment. In this study, we leverage machine ...
  • SN 2023vbg: a type IIn supernova resembling sn 2009ip, with a long-duration precursor and early-time bump 
    Goto, Sota; Yamanaka, Masayuki; Nagayama, Takahiro; Maeda, K; Kawabata, Miho; Sahu, D. K; Singh, A; Gangopadhyay, A; Dukiya, Naveen; Misra, Kuntal; Dubey, Monalisa; Ailawadhi, Bhavya (American Astronomical Society, 2025-09-10)
    Type IIn supernovae (SNe) resembling SN 2009ip (09ip-like SNe) originate from the interaction between circumstellar material (CSM) and the ejecta. This subclass not only shares similar observational properties around the ...
