  • J1216+0709: A Radio Galaxy with Three Episodes of AGN Jet Activity 
    Veeresh, Singh; Ishwara-Chandra, C. H; Kharb, P; Srivastava, S; Janardhan, P (IOP Publishing, 2016-08-01)
    We report the discovery of a "triple-double radio galaxy," J1216+0709, detected in deep low-frequency Giant Metrewave Radio Telescope (GMRT) observations. J1216+0709 is only the third radio galaxy, after B0925+420 and ...
  • Measurements of compact radio source size and structure of cometary ion tails using interplanetary scintillation at 103 MHz 
    Janardhan, P (Astronomical Society of India, 1993)
    The work contained in this thesis was carried out at the Physical Research Laboratory, Ahmedabad and describes observations of Interplanetary Scintillation (IPS), carried out since 1984, using a large 10,000 sq m dipole ...
  • Observations of PSR 0950 + 08 at 103 MHz 
    Deshpande, M. R; Vats, Hari Om; Janardhan, P; Bobra, A. D (Astronomical Society of India, 1993)
    n this article we report the possible cause of an enormously large enhancement (burst) in the ratio flux of PSR 0950 + 08. The burst was observed by two radio telescopes at Rajkot and Thaltej separated by 20 km. Simple ...
  • On the nature of compact components of radio sources at 327 MHz 
    Balasubramanian, V; Janardhan, P; Ananthakrishnan, S; Srivatsan, R (Astronomical Society of India, 1996)
    The interplanetary scintillation (IPS) survey of about 5000 radio sources carried out during 1992-93 with the Ooty Radio Telescope (ORT) at 327 MHz has resulted in the detection of compact components in about 2700 sources. ...
  • Terrestrial effects of PSR 0950 + 08 (Paper 2) 
    Vats, Hari Om; Chandra, H; Deshpande, M. R; Janardhan, P; Vyas, G. D (Astronomical Society of India, 1993)
    This article presents indirect evidence that on July 29, 1992 PSR 0950 + 08 emitted a burst of X-ray emissions along with the enhanced radio pulses. This indirect evidence is seen in the form of excess absorption of HF ...
