  • Mapping the Diffuse Ultraviolet Sky with the Galaxy Evolution Explorer 
    Murthy, J; Henry, R. C; Sujatha, N. V (IOP Publishing, 2010-12)
    We present a map of the diffuse ultraviolet cosmic background in two wavelength bands (FUV: 1530 Å and NUV: 2310 Å) over almost 75% of the sky using archival data from the Galaxy Evolution Explorer (GALEX) mission. Most ...
  • A model of the stellar radiation field in the UV 
    Sujatha, N. V; Chakraborty, P; Murthy, J; Henry, R. C (Astronomical Society of India, 2004-09)
    This work is the first step in a systematic effort to understand and predict the different components of the UV (912 A - 3000 A) radiation field over the entire sky. We have developed a model to predict the ISRF in the UV ...
  • MSX Observations of Diffuse UV Emission in Orion 
    Murthy, J; Henry, R. C; Paxton, L. J; Price, S. D (Astronomical Society of India, 2001)
    We have observed intense diffuse radiation in the UV (1400 Å - 2600 Å) from three fields around M42 in Orion. Intensities of 20000 photons cm-2 sr-1 s-1 Å-1 were observed to the east and west of M42 with 8000 photons cm-2 ...
  • 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 ...
  • Proposed SMEX to spectrally analyze the diffuse x-ray background: The Baryonic Extragalactic Structure Tracer (BEST) 
    Sanders, W. T; Henry, R. C; Bregman, J. N; Cen, R; Cox, D. P; Croft, R. A. C; Hammond, E. C; Hurwitz, M. V; McKee, C; Kimble, R. A; Porter, F. S; Serlemitsos, P. J; Stahle, C. K; Murthy, J; Raymond, J. C; Smith, R. K; Szymkowiak, A. E (SPIE--The International Society for Optical Engineering., 2003-03)
    The Baryonic Extragalactic Structure Tracer (BEST) is a SMEX-class mission that is designed to map the hot million-degree diffuse intergalactic and interstellar gas with high spectral resolution. It consists of an imaging ...
  • Upper Limits on O VI Emission From Voyager Observations 
    Murthy, J; Henry, R. C; Shelton, R. L; Holberg, J. B (American Astronomical Society, 2001-08)
    We have examined 426 Voyager fields distributed across the sky for O VI λλ1032, 1038 emission from the Galactic diffuse interstellar medium. No such emission was detected in any of our observed fields. Our most constraining ...
