A New Search For Warp's Evidence At The Southern Hemisphere
Abstract
Results where obtained from observations of the H166α radio recombination line emission in the direction of the fourth quadrant of the Galactic Plane using the 64 meter antenna of the CSIRO, located in Parkes, New South Wales, Australia.
We obtain the distribution of thermal gas in the longitude range between l=268o and l=300o and also between galactic latitude b=-3o to b=+1.5o . We resume the data cube (l, b, v) in (l,b) plots at different velocity ranges. It is apparent that the distribution of the ionized gas shows a warped structure. The goal of this research is the computation of the kinematical distances of the emission. The analysis suggests that the sources are located at a distance between 1 and 9 kpc from the sun and into a z-height range from 10 to 160 pc under the Galactic plane.- Publication:
