Multiband optical monitoring of the blazars S5 0716+714 and BL Lacertae
C. S. Stalin, Gopal-Krishna, Ram Sagar +3
We report results of multiband optical monitoring of two well known blazars, S5 0716+714 and BL Lacertae, carried out in 1996 and 2000-01 with an aim to study optical variations on…
Filling factors and scale heights of the DIG in the Milky Way
E. M. Berkhuijsen, D. Mitra, P. Mueller
The combination of dispersion measures of pulsars, distances from the model of Cordes and Lazio (2002) and emission measures from the WHAM survey enabled a statistical study of ele…
Post-outburst radio observation of the region around McNeil's nebula (V1647 Ori)
S. Vig, S. K. Ghosh, V. K. Kulkarni +1
We present post-outburst (~ 100 days after outburst) radio continuum observation of the region (~ 30' x 30') around McNeil's nebula (V1647 Orionis). The observations were carried o…
Combining visibilities from the Giant Meterwave Radio Telescope and the Nancay Radio Heliograph: High dynamic range snapshot images of the solar corona at 327 MHz
Claude Mercier, Prasad Subramanian, Alain Kerdraon +3
We report first results from an ongoing program of combining visibilities from the Giant Meterwave Radio Telescope (GMRT) and the Nancay Radio Heliograph (NRH) to produce composite…
A new constraint on the time dependence of the proton-to-electron mass ratio. Analysis of the Q 0347-383 and Q 0405-443 spectra
A. Ivanchik, P. Petitjean, D. Varshalovich +5
A new limit on the possible cosmological variation of the proton-to-electron mass ratio μ=m_p/m_e is estimated by measuring wavelengths of H_2 lines of Lyman and Werner bands from…
Outflowing material in the CSS quasar 3C48: evidence of jet-cloud interaction?
Neeraj Gupta, R. Srianand, D. J. Saikia
We report the detection of a zabs=0.3654 associated absorption-line system in the UV spectrum of the CSS quasar 3C48. The absorbing material is blue shifted with respect to the qua…
