• An intense geomagnetic storm originated from stealth coronal mass ejection: Remote and in situ observations by near radially aligned spacecraft 

  Vemareddy, P; Selva Bharathi, K (American Astronomical Society, 2025-11-20)

  We investigate the solar origin and heliospheric evolution of an intense geomagnetic storm that occurred on 2023 March 23─24. Despite multiple candidate coronal mass ejections (CMEs) observed between March 19 and 21, a ...
• A kinematic and structural study of young open clusters in the Milky Way galaxy using Gaia DR3 catalogue 

  Harsha, K. H; Subramaniam, A; Dhanush, S. R; Hariharan, D. S (Springer Nature, 2025-12)

  We aim to identify the cluster members, estimate cluster properties, study the dynamical state of the clusters as a function of mass, trace the existence of dynamical effects in massive stars, and check for spatial patterns ...
• On-axis afocal telescopes as framework for Cubesat based astronomical imagers and slit-less spectrographs 

  Mishra, Anwesh Kumar; Banerjee, Gourav; Mohan, Rekhesh; Maheswar, G (Springer Nature, 2025-12)

  CubeSats present unique opportunities for observational astronomy in the modern era. They are useful in observing difficult-to-access wavelength regions and long-term monitoring of interesting astronomical sources. However, ...
• Identification of large-scale (>100 kpc) radio jets in narrow-line seyfert 1 galaxies 

  Umayal, S; Paliya, Vaidehi S; Saikia, D. J; Stalin, C. S; Muneer, S; Maheswar, G (American Astronomical Society, 2025-12-10)

  Powerful, large-scale relativistic jets are usually associated with massive, old elliptical galaxies. This paradigm has recently been challenged by the identification of narrow-line Seyfert 1 (NLSy1) galaxies, thought to ...
• Near-sun characteristics of a CME inferred from observations in the 5303 Å coronal emission line 

  Priyal, M; Ramesh, R; Singh, J; Sasikumar Raja, K; Gopalswamy, N (American Astronomical Society, 2025-12-01)

  Using observations of the solar corona in the 5303 Å (Fe XIV) emission line with the Visible Emission Line Coronagraph (VELC) on board Aditya-L1, we estimated the electron density (Ne), thermal energy (ECME), and mass ...
