  • Kapahi, V. K (Astronomical Society of India, 1992)
    The techniques and samples being employed to find radio galaxies at high redshifts are outlined. Results obtained from the study of high-redshift galaxies, as well as attempts to elucidate this phenomenon are discussed. ...
  • Kapoor, R. C (Indian Institute of Astrophysics, 1979-11)
    A study has been made of the motion of a test particle in the background of a white hole particularly from the view point of its visibility to an observer at infinity. It is shown that radial as well as non-radial photons ...

  • Bhargava, B. N; Subrahmanyan, R. V (Indian Meteorological Department, 1960)
    F layer ionospheric data collected during the partial solar eclipses of 20 June and 14 December 1955 have been analysed. In order to study the effects of the eclipses at several heights, the electron density height profiles ...

  • Ramya, P; Reddy, B. E (Cambridge University Press, 2014-01)
    We present results of chemical abundance study of a few representative stellar streams of Galactic thick and thin discs. Arcturus stream, which was proposed to have an extragalactic origin, and a recently detected stream ...
  • Murthy, J; Henry, R. C; Paxton, L. J; Price, S. D (Astronomical Society of India, 2001)
    We have observed intense diffuse radiation in the UV (1400 Å - 2600 Å) from three fields around M42 in Orion. Intensities of 20000 photons cm-2 sr-1 s-1 Å-1 were observed to the east and west of M42 with 8000 photons cm-2 ...

  • Venkatakrishnan, P; Mathew, S. K; Srivastava, N; Bayanna, A. R; Kumar, B; Ramya, B; Jain, N; Saradava, M (Current Science Association, 2017-08)
    Multi Application Solar Telescope (MAST), a telescope for the detailed study of solar activity, was operationalized at the Udaipur Solar Observatory (USO) of Physical Research Laboratory (PRL), on 16 June 2015. This ...
  • Ramesh, R (Indian Institute of Astrophysics, Bangalore, 1998)
  • Venkatakrishnan, P (Astronomical Society of India, 2001)
    A proposal for a new ground based solar telescope of very high angular resolution is presented. The science goals that drive the need for this facility are enumerated. The proposed strategy, of combining several smaller ...

    Context. The TeV BL Lac object PG 1553+113 is one of the primary candidates for a binary supermassive black hole system. Aims. We study the flux and spectral variability of PG 1553+113 on intra-night to long-term ...
  • Ramaprakash, A. N (Astronomical Society of India, 2002)
    The IUCAA 2m telescope which is scheduled to be available for observations in early 2002, will initially have two instruments at its f/10 Cassegrain focii - the IUCAA FAint Object Spectrograph Camera (IFOSC) and the ...
  • Bhargavi, S. G (Indian Academy of Sciences, 2002-06)
    This talk focuses on the various aspects we learnt from multiband observations of GRBs both, before and during the afterglow era. A statistical analysis to estimate the probable redshifts of host galaxies using the luminosity ...
  • Aditi Agarwal (Societe Royale des Sciences de Liege, 2018-04)
    To search for optical variability on a wide range of timescales, we have carried out photometric monitoring of a dozen blazars. CCD magnitudes in B, V, R and I pass-bands were determined for > 10,000 new optical observations ...
  • Sagar, R; Gopal-Krishna; Mohan, V; Pandey, A. K; Bhatt, B. C; Wagner, S. J (The European Southern Observatory, 1999-02)
    We report multi-colour optical monitoring of the intra-day variable blazar S5 0716+71 with a dense temporal coverage over a total duration of 4 weeks in February/March 1994. Four filters (BV Johnson and RI Cousins) were ...
