Intermittent jet activity in the radio galaxy 4C29.30?
M. Jamrozy, C. Konar, D. J. Saikia +3
We present radio observations at frequencies ranging from 240 to 8460 MHz of the radio galaxy 4C29.30 (J0840+2949) using the Giant Metrewave Radio Telescope (GMRT), the Very Large…
The effect of Pulse profile evolution on Pulsar Dispersion Measure
Amrit Lal Ahuja, Dipanjan Mitra, Yashwant Gupta
In an earlier paper (Ahuja, et al, 2005), based on simultaneous multi-frequency observations with the Giant Metrewave Radio Telescope (GMRT), we reported the variation of pulsar di…
Intra-night Optical Variability of Luminous Radio Quiet QSOs
A. C. Gupta, U. C. Joshi
In the present paper we report the detection of intra-night variability in some of the RQQSOs and one LDQ. To study intra-night variability, we carried out photometric monitoring o…
Mass Limit on Nemesis
Varun Bhalerao, M. N. Vahia
We assume that if the sun has a companion, it has a period of 27 Myr corresponding to the periodicity seen in cometary impacts on earth. Based on this assumption, it is seen that t…
Low-frequency Carbon Recombination Lines towards HI self-absorption features in the Galactic Plane
D. Anish Roshi, Nimisha G. Kantharia, K. R. Anantharamaiah
A survey of radio recombination lines (RLs) in the Galactic plane ( 332° 89°) near 327 MHz made using the Ooty Radio Telescope (ORT) has detected carbon RLs from all the…
