    We report on multiwavelength observations, ranging from X-ray to radio wave bands, of the IPN-localized gamma-ray burst GRB 070125. Spectroscopic observations reveal the presence of absorption lines due to O I, Si II, and ...
  • Bhatt, B. C; Prabhu, T. P; Anupama, G. C (Astronomical Society of India, 2000)
    A brief summary of site characteristics of Indian Astronomical Observatory, Hanle, Ladakh (altitude 4500 m), is presented based on a survey being carried out since the last four years.

    The evolution of the spin rate of Comet 9P/Tempel 1 through two perihelion passages (in 2000 and 2005) is determined from 1922 Earth-based observations taken over a period of 13 year as part of a World-Wide observing ...
  • Chauhan, N; Ogura, K; Pandey, A. K; Samal, M. R; Bhatt, B. C (Astronomical Society of Japan, 2011-08)
    The H II region IC 1848 harbors a lot of intricate elephant trunk-like structures that look morphologically different from usual bright-rimmed clouds (BRCs). Of particular interest is a concentration of thin and long ...
