PublicationMolecular and low excitation emission in high mass post-main-sequence nebulae
A broad range of type I post-main-sequence nebulae have been mapped and studied spectroscopically in the J = 1 - 0, J = 2 - 1, and J = 3 - 2 transitions of CO...

PublicationMultidimensional interpolation using artificial neural networks: Application to an H I cloud in Perseus
In this paper we propose a method for interpolating multidimensional unbinned data, which could also be sparse, using artificial neural network techniques. An...

PublicationProperties of an H I-selected galaxy sample
We analyze the properties of a sample of galaxies identified in a 21cm, H I-line survey of selected areas in the Perseus-Pisces supercluster and its foreground...
