  • Far-ultraviolet scattering by dust in Orion 
    Shalima, P; Sujatha, N. V; Murthy, J; Henry, R. C; Sahnow, D. J (Blackwell Publishing, 2006-04)
    We have modelled diffuse far-ultraviolet (FUV) spectrum observed by the Far Ultraviolet Spectroscopic Explorer (FUSE) near M42 as the scattering of the starlight from the Trapezium stars by dust in front of the nebula. The ...
  • Measurement of Dust Optical Properties in Coalsack Nebula 
    Sujatha, N. V; Murthy, J; Shalima, P (University of Chicago Press, 2007-08)
    We have used FUSE and Voyager observations of dust-scattered starlight in the neighborhood of the Coalsack Nebula to derive the optical constants of the dust grains. The albedo is consistent with a value of 0.28 ± 0.04, ...
  • Modelling of dust scattering toward the Coalsack 
    Shalima, P; Murthy, J (Royal Astronomical Society, 2004-08)
    Murthy, Henry & Holberg discovered intense far-ultraviolet (FUV) (λλ912-1600) emission from the direction of the Coalsack molecular cloud 10 years ago. We have used their results in conjunction with a Monte Carlo model for ...
  • Modelling the diffuse ultraviolet radiation observed by Dynamics Explorer 1 
    Shalima, P; Murthy, J; Fix, J. D (Wiley Blackwell, 2010-10)
    The Dynamics Explorer spacecraft, DE-1, has undertaken two sky surveys in the far-ultraviolet regime, covering a wide variety of Galactic latitudes. We have used a single scattering dust model to probe into the optical ...
  • Probing the Physics of Narrow-line Regions in Active Galaxies. IV. Full Data Release of the Siding Spring Southern Seyfert Spectroscopic Snapshot Survey (S7) 
    Thomas, A. D; Dopita, M. A; Shastri, P; Davies, R; Hampton, E; Kewley, L; Banfield, J; Groves, B; James, B. L; Jin, C; Juneau, S; Kharb, P; Lalitha, S; Scharwachter, J; Shalima, P; Sundar, M. N; Sutherland, R; Zaw, I (IOP Publishing, 2017-09)
    We present the second and final data release of the Siding Spring Southern Seyfert Spectroscopic Snapshot Survey (S7). Data are presented for 63 new galaxies not included in the first data release, and we provide 2D ...
  • Studies of Interstellar Dust 
    Shalima, P (Indian Institute of Astrophysics, Bangalore, 2005-08)
  • TAUVEX flight calibrations: Plans and challenges 
    Safonova, M; Shalima, P; Murthy, J (Astronomical Society of India, 2009-06)
    The operational tasks for the Performance Verification (PV) and calibration phase in the first year of TAUVEX operation are presented. The new challenges regarding the possible reduction in sensitivity are outlined and are ...
  • Unravelling the nuclear dust morphology of NGC 1365: a two-phase polar–RAT model for the ultraviolet to infrared spectral energy distribution 
    Swain, Subhashree; Shalima, P; Latha, K. V. P (Oxford University Press on behalf of Royal Astronomical Society, 2024-01)
    We present a 3D radiative transfer model for the spectral energy distribution (SED) of NGC 1365, which is a ‘changing look’ Seyfert 1.8 type active galactic nucleus (AGN). The SED from the ultraviolet (UV) to the infrared ...
