  • Multiwavelength study of the variability in blazars 
    Baliyan, K. S (Astronomical Society of India, 2001)
    Blazars are the radio-loud AGNs with polarized, highly luminous and rapidly variable non-thermal continuum emission ranging from radio to ??rays, from a relativistic jet. These features are interpreted in terms of the ...
  • A multiwavelength study of three hybrid blazars 
    Stanley, E. C; Kharb, P; Lister, M. L; Marshall, H. L; O'Dea, C; Baum, S (IOP Publishing, 2015-07-01)
    We present multiwavelength imaging observations of PKS 1045−188, 8C 1849+670, and PKS 2216−038, three radio-loud active galactic nuclei from the MOJAVE-Chandra Sample that straddle the Fanaroff-Riley (FR) boundary between ...
  • A multiwavelength view of the open cluster NGC 2527: discovery of active stars 
    Shah, N; Singh, K. P; Subramaniam, A (Oxford University Press on behalf of the Royal Astronomical Society, 2020-04)
    Star clusters are ideal platforms for categorizing X-ray emitting stars and to study X-ray emission as a function of stellar age and activity. We present a comprehensive study of an open star cluster, NGC 2527, by combining ...
  • MUSSES2020J: The Earliest Discovery of a Fast Blue Ultraluminous Transient at Redshift 1.063 
    Jiang, Ji-an; Yasuda, Naoki; Maeda, Keiichi; Tominaga, Nozomu; Doi, Mamoru; Ivezic, Zeljko; Yoachim, Peter; Uno, Kohki; Moriya, Takashi J; Kumar, Brajesh; Pan, Yen-Chen; Tanaka, Masayuki; Tanaka, Masaomi; Nomoto, Kenichi; Jha, Saurabh W; Ruiz-Lapuente, Pilar; Jones, David; Shigeyama, Toshikazu; Suzuki, Nao; Kokubo, Mitsuru; Furusawa, Hisanori; Miyazaki, Satoshi; Connolly, Andrew J; Sahu, D. K; Anupama, G. C (IOP Publishing, 2022-07-10)
    In this Letter, we report the discovery of an ultraluminous fast-evolving transient in rest-frame UV wavelengths, MUSSES2020J, soon after its occurrence by using the Hyper Suprime-Cam (HSC) mounted on the 8.2 m Subaru ...
  • Mutual phenomena of Jovian satellites 
    Vasundhara, R (Indian Academy of Sciences, 1991-03)
    Mutual eclipses of Galilean satellites were observed and the results are given. The observations are fitted by utilizing Lambert's law, theoretical models assuming a uniform disk, and Lommel-Seeliger's law which describes ...
  • Mutual phenomena of Jovian satellites in 1990-1991 
    Vasundhara, R (Astronomical Society of India, 1990-03)
  • Mutual phenomena of the Galilean satellites: an analysis of the 1991 observations from VBO 
    Vasundhara, R (European Southern Observatory, 1994-01)
    Results of analysis of seventeen mutual events, of the Galilean satellites, observed at the Vainu Bappu Observatory (VBO) during the 1991 are presented. The light curves were fitted with theoretical models to derive the ...
  • My encounter with Astronomy 
    Abhyankar, K. D (Astronomical Society of India, 1990)
  • My encounter with astronomy : early years 
    Bhattacharyya, J. C (Astronomical Society of India, 1997)
  • My encounter with astronomy : later years 
    Bhattacharyya, J. C (Astronomical Society of India, 1997)
  • My experiences as an astronomer and a survey of binary star research carried out at CASA 
    Sarma, M. B. K (Astronomical Society of India, 1997)
  • My forty years in astronomy 
    Vardya, M. S (Astronomical Society of India, 1997)
  • My life as an astronomer 
    Alladin, S. M (Astronomical Society of India, 1997)
    Factors which motivated me to pursue Astronomy are discussed. Dynamics of galaxies has been the principal area of my research. Work done by me and my associates in this field is indicated. Our work on frequency of occurrence ...
  • Myopic aberrations: Simulation based comparison of curvature and Hartmann Shack wavefront sensors 
    Roopashree, M. B; Vyas, A; Weddell, S. J; Prasad, B. R (Elsevier B.V., 2014-02-01)
    In comparison with a Hartmann Shack wavefront sensor, the curvature wavefront sensor is known for its higher sensitivity and greater dynamic range. The aim of this study is to numerically investigate the merits of using a ...
  • The mysterious bar of the large magellanic cloud: what is it? 
    Subramaniam, A; Subramanian, S (Institute of Physics, 2009-09)
    The bar of the Large Magellanic Cloud (LMC) is one of the prominent, but controversial, features regarding its location with respect to the disk of the LMC. In order to study the relative location of the bar with respect ...
  • The mystery of the cosmic diffuse ultraviolet background radiation 
    Henry, R. C; Murthy, J; Overduin, James; Tyler, Joshua (IOP Publishing Ltd, 2015-01-01)
    The diffuse cosmic background radiation in the Galaxy Evolution Explorer far-ultraviolet (FUV, 1300-1700 Å) is deduced to originate only partially in the dust-scattered radiation of FUV-emitting stars: the source of a ...
  • Myths, Superstitions and Propaganda in Scientific Age 
    Banyal, R. K (2012-01)
    From prehistoric times, humans have evolved as pattern seeking and storytelling species. While the capacity to find patterns and infer meanings had obvious advantages for survival, the brain is not always successful in ...
  • M∙ − σ relation in spherical systems 
    Bhattacharyya, D; Mangalam, A (Indian Academy of Sciences, 2018-02)
    To investigate the M∙−σ relation, we consider realistic elliptical galaxy profiles that are taken to follow a single power-law density profile given by Ï (r)=Ï 0(r/r0)−γ or the Nuker intensity profile. We calculate ...
  • N-body problem 
    Bhatnagar, K. B; Saha, L. M (Astronomical Society of India, 1993-03)
    This is a review article on the N-body problem. The development of the qualitative methods regarding the various topics of Celestial Mechanics are presented in a systematic way starting from the early researches of the ...
  • N-Body Simulation of a Deeply Penetrating Collision Between Unequal Galaxies 
    Namboodiri, P. M. S; Sastry, K. S; Narasimhan, K. S. V. S (Kluwer Academic Publishers, 1998-09)
    We study the tidal effects of a deeply penetrating collision between two spherical galaxies, one twice massive but less dense than the other, by numerical simulations. We consider the relative motion of the galaxies to be ...
