  • Monitoring of AGNs for variability from MIRO 
    Baliyan, K. S; Joshi, U. C; Ganesh, S (Astronomical Society of India, 2005-06)
    As a long term programme, a sample of blazars is being monitored from Mt Abu Infrared Observatory (MIRO). Blazars are the radio-loud AGNs with polarized, highly luminous and rapidly variable non-thermal continuum emission ...
  • Multiwavelength study of the inner regions of the Milky Way Galaxy 
    Ganesh, S; Joshi, U. C; Baliyan, K. S; Omont, A; Simon, G (Astronomical Society of India, 2005-06)
    The inner regions of the Milky Way have received a lot of attention in recent years. Multiwavelength observations have been made at varying spatial, temporal and spectral resolutions. We have studied the inner regions of ...
  • 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 ...
  • Near infrared photometry of the young open cluster NGC 1960 
    Hasan, P; Kilambi, G. C; Baliyan, K. S (Astronomical Society of India, 2002-09)
    We present the preliminary results of observations of NGC 1960 which was observed from the Mt Abu Infrared Observatory, using the NICMOS3 infrared array mounted on the 1.2 m Cassegrain focus telescope. The observations ...

    Hasan, P; Kilambi, G. C; Baliyan, K. S (Astronomical Society of India, 2003)
    This work involves near infrared photometry of the young cluster NGC 2384. Observations were taken at the Mt Abu Infrared Observatory using the NIC-MOS3 detector in February 2000. The distance to the cluster is obtained ...
  • Near Infrared Survey of the Galactic Nuclear Bulge Region 
    Baliyan, K. S; Ganesh, S; Joshi, U. C; Glass, I. S (Astronomical Society of India, 2003)
    Inner 300 pc of the Galactic Center region is surveyed with the SIR-IUS camera mounted on the InfraRed Survey Facility (IRSF) telescope of the SAAO, during June-July 2002, resulting in the deepest near infrared view of the ...
  • Near IR study of the young cluster NGC 2453 
    Hasan, P; Kilambi, G. C; Baliyan, K. S (Astronomical Society of India, 2001)
    In an attempt to understand early phases of stellar evolution and star formation, we have taken up the study of extremely young star clusters in the near infrared wavebands. These clusters are deeply embedded inside the ...
  • Photoionization cross sections for the Fe XVII ion 
    Baliyan, K. S; Joshi, U. C (Astronomical Society of India, 2000)
  • PRLNIC3 observations of star forming cloud L1340 
    Ganesh, S; Joshi, U. C; Baliyan, K. S; Shah, C. R; Jain, J. K; Rajpurohit, G. S; Sanchawala, K; Saha, A. B (Astronomical Society of India, 2001)
    Due mainly to high extinction in optical, the structure of our galaxy, Milky Way, is not very well understood. The Galactic disk and bulge contain a host of heavily reddened open clusters which are deeply embedded within ...

C; Perri, M; Pihajoki, P; Poyner, G; Provencal, J; Pursimo, T; Raj, A; 29 others (Molecular Diversity Preservation International, 2016-12)
    We analyse the light curve in the R band of the blazar OJ287, gathered during the 2015/2016 observing season. We did a search for quasi-periodic oscillations (QPOs) using several methods over a wide range of timescales. ...
