  • Parsec-scale radio morphology in Seyfert galaxies 
    Lal, D. V; Shastri, P; Gabuzda, D. C (The Astronomical Society of the Pacific, 2001)
  • Pc-scale study of radio galaxies and BL Lacs 
    Kharb, P; Shastri, P; Gabuzda, D. C (Elsevier, 2003-10)
    We study two aspects of the differences between Active Galactic Nuclei (AGN) of the two Fanaroff-Riley types in order to investigate the causes of the F-R divide. We: (a) contrast the properties of the optical cores in ...
  • Rotation measures across parsec-scale jets of fanaroff-Riley Type I radio galaxies 
    Kharb, P; Gabuzda, D. C; O'Dea, C. P; Shastri, P; Baum, S. A (Institute of Physics, 2009-04)
    We present the results of a parsec-scale polarization study of three FRI radio galaxies—3C66B, 3C78, and 3C264—obtained with Very Long Baseline Interferometry at 5, 8, and 15 GHz. Parsec-scale polarization has been detected ...
  • Seyfert Galaxies on milliarcsecond scales 
    Lal, D. V; Shastri, P; Gabuzda, D. C (Taylor and Francis, 2001-08)
    We present our results from global VLBI observations of a sample of Seyfert galaxies at 5 GHz. Our goal was to test predictions of the Unified Scheme for Seyfert galaxies, in which observed differences between Seyferts of ...
  • Seyfert Galaxies: Nuclear Radio Structure and Unification 
    Lal, D. V; Shastri, P; Gabuzda, D. C (IOP Publishing, 2011-04-10)
    A radio study of a carefully selected sample of 20 Seyfert galaxies that are matched in orientation-independent parameters, which are measures of intrinsic active galactic nucleus power and host galaxy properties, is ...
  • When less is more: Are radio galaxies below the Fanaroff-Riley break more polarized on parsec scales? 
    Kharb, P; Shastri, P; Gabuzda, D. C (IOP Publishing, 2005-10-20)
    We present images showing the first detections of polarizations on parsec scales in the nuclei of four Fanaroof-Riley type I (low-luminosity) radio galaxies. Observations with Very long Baseline Interferomatry at lamda 3.6 ...
