The arcsecond scale properties of 6 UHBLs
Abstract
In this work, by using the VLA archive data, we present the arcsecond scale structure and radio spectrum properties of six UHBLs, which were selected from Nieppola et al. 2006 , including all the UHBLs available with VLA archive data at L, C, X band. Our preliminary result shows that spectrum of UHBLs seems to be steeper than normal HBLs.
