Welcome to the Digital Repository of Indian Institute of Astrophysics

This digital repository of Indian Institute of Astrophysics (IIAP), Bangalore, India is developed to capture, organize disseminate and preserve the research publications of IIAP. It also includes the in-house technical reports and annual reports in addition to various other grey literatures created within the institute.You can search, browse and access full text of these publications from the repository.

  • An alternative iterative scheme to the full non-LTE transfer problem with coherent scattering in the atom’s frame 
    Lagache, T; Sampoorna, M; Paletou, F (Oxford University Press on behalf of the Royal Astronomical Society, 2025-01)
    We propose an alternative scheme for the computation of the so-called ‘full non-LTE’ (non-local thermodynamic equilibrium) radiative transfer problem, assuming coherent scattering in the atom’s frame. This generalized ...
  • A new broad-band atmospheric dispersion corrector for HROS-TMT 
    Manjunath, B; Sivarani, T; Wehbe, Bachar; Hasan, Amirul; Chandra, B; Divakar, D. K; Unni, Athira; Parvathy, M; Surya, Arun; Saraf, Pallavi (Oxford University Press on behalf of the Royal Astronomical Society, 2025-01)
    Atmospheric dispersion causes light from celestial objects with different wavelengths to refract at varying angles as it passes through Earth’s atmosphere. This effect results in an elongated image at the focal plane of a ...
  • Star formation in interacting galaxy systems: UVIT imaging of NGC 7252 and NGC 5291 
    Santhosh, Geethika; Rajalakshmi, Rakhi; George, K; Subramanian, S; Indulekha, K (Cambridge University Press on behalf of Astronomical Society of Australia, 2025-04)
    Interactions play a significant role in the formation and evolution of galaxies in the Universe. The galaxy systems, NGC 7252 and NGC 5291, are two nearby interacting systems that are hosting tidal dwarf galaxies (TDGs) ...
  • Magnetic fields on different spatial scales of the L328 cloud 
    Gupta, Shivani; Archana Soam; Karoly, Janik; Lee, Chang Won; Maheswar, G (Oxford University Press on behalf of Royal Astronomical Society, 2025-06)
    L328 core has three sub-cores S1, S2, and S3, among which the sub-core S2 contains L328-IRS, a Very Low Luminosity Object, which shows a CO bipolar outflow. Earlier investigations of L328 mapped cloud/envelope (parsec-scale) ...
  • Comprehensive variability analysis of blazars using Fermi light curves across multiple timescales 
    Shah, Zahir; Dar, Athar A; Akbar, Sikandar; Peer, Anjum; Malik, Zahoor; Manzoor, Aaqib; Ahanger, Sajad; Tantry, Javaid; Nazir, Zeeshan; Bose, D; Magray, Mushtaq (American Physical Society, 2025-06-15)
    In this study, we conducted a systematic analysis of long-term Fermi-LAT γ-ray data for a sample of blazars, including flat spectrum radio quasars (FSRQs), BL Lacertae objects (BL Lacs), and blazar candidates of unknown ...
