    A low-threshold energy, high-sensitivity gamma-ray telescope, MACE (for Major Atmospheric Cerenkov Experiment) is proposed to be built in India for explorations of gamma-ray sky in 100's keV - 10's GeV photon energy range, ...
  • Suthar, R. L; Guha, S; Bandopadhyay, K; Mishra, V. K; Koul, R; Bhat, C. L (Astronomical Society of India, 2002)
    A low-threshold energy, high-sensitivity gamma-ray telescope, MACE (for Major Atmospheric Cerenkov Experiment) is proposed to be built in India for explorations of gamma-ray sky in 100's keV - 10's GeV photon energy range, ...
  • Jeffery, C. S; Kameswara Rao, N; Lambert, D. L (Oxford University Press on behalf of the Royal Astronomical Society, 2020-04)
    The hydrogen-deficient star DY Cen has been reported as an R CrB-type variable, an extreme helium star (with some hydrogen), and as a single-lined spectroscopic binary. It has been associated with a dramatic change in ...
  • Vaghmare, K; Barway, S; Vaisanen, Petri; Ramphul, Rajin; Wadadekar, Yogesh; Kembhavi, Ajit K (Oxford University Press on behalf of the Royal Astronomical Society, 2018-11)
    We present a SALT-RSS spectroscopic study of a sample of S0 galaxies established by Vaghmare et al. (2015) as having pseudobulges using a combination of photometric criteria. We extract the spectra of various regions along ...
  • Naik, P. C; Satpathy, L (Astronomical Society of India, 1998-03)
    Samanta Chandra Sekhar (1835-1904), popularly known as Pathani Samabta in Orissa, worked in astronomy following traditional methods, completely unaware of the telescope and other aids developed in the west. He took ...

    SAO 244567 (Hen 1357 = CPD -59 deg 6926 = IRAS 17119-5926) is an IRAS source with far infrared colors and flux distribution similar to those of planetary nebulae. The IUE ultraviolet spectra obtained in July 1988 and April ...
  • Bhatt, H. C; Sagar, R; Subramaniam, A; Gorti, U; Chandrasekhar, T; Ashok, N. M; Ragland, S (European Southern Observatory, 1994-09)
    Photometric and spectroscopic observations of the star SAO 75669 in the region of the high galactic latitude molecular cloud MBM 12 are presented. The optical, near-infrared and far-infrared IRAS photometric magnitudes ...

  • Raman, C. V (Astronomical Society of India, 1914-04)
  • Bhattacharyya, J. C; Bappu, M. K. V (Nature Publishing Group, 1977-12)
    A photoelectric record of the occultation of SAO 158687 by Uranus on March 10, 1977, is analyzed. The observed variation in the intensity of the star's light is shown to indicate the presence of four zones, which are ...
  • Sivaram, C (Springer, 1993-09)
    The notion of discrete scale transformations is invoked to suggest strong links between fundamental interactions and cosmology giving rise to a hierarchy of cosmic scales.
  • Seetha, S (Astronomical Society of India, 2002-09)
    The scanning sky monitor (SSM) on the ASTROSAT is an instrument to be used for detecting and locating new x-ray transients and to study the long term behavior of the known bright x-ray sources in the celestial sphere. ...
