Abstract:
In this paper, we present the first extended catalogue of far-infrared
fluxes of Galactic bubbles. Fluxes were estimated for 1814 bubbles,
defined here as the 'golden sample', and were selected from the
Milky Way Project First Data Release (Simpson et al.,
2012MNRAS.424.2442S 2012MNRAS.424.2442S, Cat. J/MNRAS/424/2442) The golden sample was
comprised of bubbles identified within the Wide-field Infrared Survey
Explorer (WISE) dataset (using 12- and 22-um images) and Herschel data
(using 70-, 160-, 250-, 350- and 500-um wavelength images). Flux
estimation was achieved initially via classical aperture photometry
and then by an alternative image analysis algorithm that used active
contours. The accuracy of the two methods was tested by comparing the
estimated fluxes for a sample of bubbles, made up of 126 HII regions
and 43 planetary nebulae, which were identified by Anderson et al. The
results of this paper demonstrate that a good agreement between the
two was found. This is by far the largest and most homogeneous
catalogue of infrared fluxes measured for Galactic bubbles and it is a
step towards the fully automated analysis of astronomical datasets.
Description:
We consider the Galactic bubble catalogue produced by Simpson et al.
(2012MNRAS.424.2442S 2012MNRAS.424.2442S, Cat. J/MNRAS/424/2442) as a database of
confirmed bubbles.
The images from which we estimated the fluxes emitted by the bubbles
of the golden sample are taken from the WISE and Hi-GAL surveys.
As an example of the final catalogue, we show table with the fluxes
measured with the two methods for a collection of bubbles taken from
the golden sample.
