  • Latha, K. V. P; Angom, D; Das, B. P; Mukherjee, D (The American Physical Society, 2009-08-21)
    The electric dipole moment of atomic Hg-199 induced by the nuclear Schiff moment and the tensor-pseudotensor electron-nucleus interactions are calculated. For this, we develop and employ a novel method based on the ...
  • Sengupta, S; Krishan, V (The American Astronomical Society, 2001-11)
    The theoretical analysis and observational evidence indicate that a brown dwarf with an effective temperature greater than 1300 K would have a dust cloud in its atmosphere. In this Letter, we show that dust scattering ...

    One of the major science goals of square kilometre array (SKA) is to understand the role played by atomic hydrogen (HI) gas in the evolution of galaxies throughout cosmic time. The hyperfine transition line of the hydrogen ...
  • Sigl, G; Lee, S; Bhattacharjee, P; Yoshida, S (The American astronomical Society, 1999-04)
    We explore scenarios where the highest energy cosmic rays are produced by new particle physics near the grand unification scale. Using detailed numerical simulations of extragalactic nucleon, γ-ray, and neutrino propagation, ...
  • Mallick, Anohita; Reddy, B. E; Muthumariappan, C (Oxford University Press on behalf of Royal Astronomical Society, 2022-04)
    We have performed a search among low-mass red giants for finding evidence for merger scenario for triggering He-flash and subsequent Li enhancement. We chose a sample of red giants from GALAH survey with well-measured Li ...

V (Oxford University Press on behalf of Royal Astronomical Society, 2022-04)
    Multipulsed GRB 190530A, detected by the Gamma-ray Burst Monitor (GBM) and Large Area Telescope onboard Fermi, is the sixth most fluent GBM burst detected so far. This paper presents the timing, spectral, and polarimetric ...
  • Roy, S; Sur, Sharanya; Subramanian, K; Mangalam, A; Seshadri, T. R; Chand, H (Indian Academy of Sciences, 2016-12)
    Origin of magnetic fields, its structure and effects on dynamical processes in stars to galaxies are not well understood. Lack of a direct probe has remained a problem for its study. The first phase of Square Kilometre ...
  • Majumdar, Subhabrata (Indian Institute of Astrophysics, Bangalore, 2001-06)
  • Paragi, Z; Frey, S; Kaaret, P; Cseh, D; Overzier, R; Preethi, K (IOP Publishing, 2014-08-10)
    Recently, Nyland et al. argued that the radio emission observed in the center of the dwarf galaxy NGC 404 originates in a low-luminosity active galactic nucleus powered by a massive black hole (MBH, M lsim 106 M ☉). ...
  • Chand, H; Rakshit, S; Jalan, P; Ojha, V; Srianand, R; Vivek, M; Mishra, S; Omar, A; Kumar, P; Joshi, R; Gopal Krishna; Kumar, R (Societe Royale des Sciences de Liege, 2018-04)
    : We discuss three long term observational programmes to probe the central engine and environment of active galactic nuclei (AGN) using the recently installed ARIES 1.3-m and 3.6-m telescopes. The first programme is on ...
  • Majumdar, S (American Astronomical Society, 2001-07)
    Study of the primary anisotropies of the cosmic microwave background (CMB) can be used to determine the cosmological parameters to a very high precision. The power spectrum of the secondary CMB anisotropies due to the ...
  • Goswami, A.; Jameela, S (Societe Royale des Sciences de Liege, 2019-10)
    The origin and evolution of neutron-capture elements in our Galaxy is poorly understood. In this work, we have attempted to understand the Galactic s-process nucleosynthesis using barium stars as probes. We have performed ...
  • Hasan, S. S; Zahn, J. P; Christensen-Dalsgaard, J (EDP Sciences, 2005-12)

  • Dinh, V. T; Muller, S; Lim, J; Kwok, S; Muthu, C (The American Astronomical Society, 2009-05-20)
    We have used the submillimeter array to image the molecular envelope around the yellow hypergiant IRC+10420. Our observations reveal a large and clumpy expanding envelope around the star. The molecular envelope shows a ...
  • Shejeelammal, J; Goswami, A (IOP Publishing, 2021-11-01)

  • Marley, Mark S; Sengupta, S (Wiley-Blackwell, 2011-11)
    It is becoming clear that the atmospheres of the young, self-luminous extrasolar gi- ant planets imaged to date are dusty. Planets with dusty atmospheres may exhibit detectable amounts of linear polarization in the ...
