  • Are Nuclear Hot Spots in Galaxies Sites of Sequential Star Formation? 
    Korchagin, V; Kembhavi, A. K; Mayya, Y. D; Prabhu, T. P (The American Astronomical Society, 1995-06)
    We investigate self-regulated propagation of stars formation, which is one of the possible scenarios of stars formation in molecular clouds fragmented into cold dense structures with masses lying near the Jeans limit. ...

    Singh, K. P; Bhat, P. N; Prabhu, T. P; Kembhavi, A. K (Springer, 1995-10)
    We report imaging observations of Hα+[N II] nebulosities in seven early type galaxies viz., NGC 1399, NGC 1600, NGC 2563, NGC 4203, NGC 4636, NGC 4753 and NGC 5044. These are primarily X-ray bright galaxies which are the ...
  • Dust and ionized gas in NGC 3607 
    Singh, K. P; Prabhu, T. P; Kembhavi, A. K; Bhat, P. N (The American Astronomical Society, 1994-04)
    We report the detection of a broad dust ring in the X-ray-bright elliptical galaxy NGC 3607, the dominant member of a nearby group of galaxies. The inner radius of the ring is approximately 1.3 kpc from the nucleus and has ...
  • Dust in an extragalactic environment : The case of NGC 2907 
    Patil, M. K; Pandey, S. K; Kembhavi, A. K; Singh, M (Astronomical Society of India, 2001)
    We have carried out a detailed CCD surface photometric analysis of the lenticular galaxy NGC 2907, containing multiple dust lanes, with the objective of studying properties of dust in an extragalactic environment. Measurements ...
  • Dust Properties in Early-type Galaxies 
    Patil, M. K; Sahu, D. K; Pandey, S. K; Kembhavi, A. K; Joshi, U. C; Baliyan, K. S; Singh, M (Astronomical Society of India, 2002-09)
  • An Expanding Plasma Model for the X-ray/radio knots in KPC-scale Jets of Active Galactic Nuclei 
    Sahayanathan, S; Misra, R; Kembhavi, A. K; Kaul, C. L (Astronomical Society of India, 2003)
    We model the observed X-ray/radio knots in Active Galactic Nuclei (AGN) as isotropically expanding spherical plasma clouds fed continously by non-thermal electrons. The time-dependent electron distribution and the emitted ...
  • A highly flattened stellar disk in the elliptical galaxy NGC 4564 
    Sahu, D. K; Pandey, S. K; Kembhavi, A. K (Astronomical Society of India, 1996)
    We present the R band isophotal shape analysis of the E6 elliptical galaxy NGC 4564 by fittng ellipses to the observed isophotes using Fourier expansion procedure. The galaxy is found to have pointy isophotes, showing ...
  • Ionized Gas in Elliptical Galaxies 
    Singh, K. P; Prabhu, T. P; Kembhavi, A. K; Bhat, P. N (Indian Academy of Sciences, 1995-06)
    We report observations of H alpha nebulosities in the X-ray bright elliptical galaxies which are members of nearby groups of galaxies or clusters. Our sample includes NGC 1399, NGC 1600, NGC 2563, NGC 3607, NGC 4203, ...
  • Lenticular and other galaxies 
    Kembhavi, A. K; Barway, Sudhanshu; Ravi Kumar, C. D (Astronomical Society of India, 2005-06)
    We describe in this paper the surface photometry of a set of lenticular galaxies. We then consider important correlations between morphological parameters of the bulges of lenticulars and other types of galaxies
  • Morphological analysis of intermediate redshift galaxies using the HST/ACS GOODS survey 
    Rawat, A; Kembhavi, A. K (Astronomical Society of India, 2005-06)
    We have been involved in performing photometry and morpholog- ical analysis of a large, complete sample of galaxies in the intermediate redshift range using the high resolution images obtained by the Great Observatories ...
  • Optical and near-IR imaging of dusty ellipticals 
    Pandey, S. K; Sahu, D. K; Kembhavi, A. K; McCarthy, P. J (Astronomical Society of India, 2001)
    In this paper we present some of the results of imaging observations of dusty ellipticals in the optical B & R bands as well as in near IR K'-band taken at the Las Campanas Observatory, Chile. We derive radial profiles of ...
  • Properties of dust extinction in NGC 2076 
    Sahu, D. K; Pandey, S. K; Kembhavi, A. K (Astronomical Society of India, 1999)
    Early-type galaxies with large-scale dust are suitable objects to investigate the propeties of dust extinction in extragalactic environments because the underlying galaxies have fairly smooth distribution of the starlight. ...
  • Surface photometry of ellipticals: Radio and cluster galaxies 
    Singh, K. P; Bhat, P. N; Prabhu, T. P; Kembhavi, A. K (Astronomical Society of India, 1993)
    Broad-band surface photometry in V, R and I colors is presented for three elliptical galaxies immersed in hot intracluster gas emitting X-rays due to thermal bremsstrahlung. The galaxies are (1) a cD galaxy, and (2) a radio ...
