GALEX Diffuse UV Background

1. Introduction

We present a systematic account of the status of the GALEX Diffuse UV Background project of Dick Henry, Jayant Murthy, Luciana Bianchi, P. Shalima, and N.V. Sujatha, with a roadmap for the future.

We submitted our GALEX Cycle 3 Archival Proposal on 2006 July 5, in the hope of obtaining support to expand our research, and to complete this site. (We also submitted the required xml file; note that the file has unix line endings. This displays perfectly in Internet Explorer, but NOT in Safari I regret to say!)

In Cycles One and Two, we were successful with a Legacy Proposal (there are only 3 GALEX Legacy projects).

Here is the status (as of 2006 June 16) of our Cycles 1/2 GALEX observing program (items in RED are not yet at MAST).

Here is the GALEX POSTER we presented at the 2006 January AAS Meeting, Washington, DC

Here is a paper that is in press at the CJAA analyzing archival GALEX Deep Imaging Survey First Data Release images, to exhibit our analysis techniques.

If you need background information on this field, here are Annual Review papers by Stu Bowyer (and also one by Dick Henry), a detailed paper on our Voyager results by Jayant Murthy et al., a detailed paper by Dick & Jayant presented at STScI, and an ApJ letter by Dick.
We draw your attention to the modeling work that we have been carrying out, for predicting dust-scattered starlight:

        A model of the stellar radiation field in the UV,
        N. V. Sujatha, Pavan Chakraborty, Jayant Murthy and R. C. Henry,
        BASI, 32, 151, 2004

        Dust Properties in the FUV in Ophiuchus,
        N. V. Sujatha, P. Shalima, J. Murthy, & R. C. Henry,
        ApJ, 633, 257, 2005

        Far-ultraviolet scattering by dust in Orion,
        P. Shalima, N. V. Sujath, Jayant Murthy, Richard Conn Henry, and David Sahnow,
        MNRAS, 367, 1686, 2006

        Modeling of dust properties in the FUV towards the Coalsack,
        N. V. Sujatha, P. Shalima, Jayant Murthy, & Richard Conn Henry,
        ApJ, submitted, 2006

Next, we give a detailed presentation of our results for our first observing program target.
