Abstract
We report the discovery of a giant double-lobed (lobe-core-lobe)
radio-continuum structure associated with QSO J0443.8-6141 at z=0.72. This
QSO was originally identified during the follow-up of a sample of ROSAT All
Sky Survey sources at radio and optical frequencies. With a linear size of
~0.77 Mpc, QSO J0443.8-6141 is classified as a giant radio source (GRS);
based on its physical properties, we classify QSO J0443.8-6141 as a FR II
radio galaxy. High-resolution observations are required to reliably identify
GRSs; the next generation of southern sky radio and optical surveys will be
crucial to increasing our sample of these objects.
期刊介绍：
Serbian Astronomical Journal publishes original observations and researches in all branches of astronomy. The journal publishes:
Invited Reviews - review article on some up-to-date topic in astronomy, astrophysics and related fields (written upon invitation only),
Original Scientific Papers - article in which are presented previously unpublished author''s own scientific results,
Preliminary Reports - original scientific paper, but shorter in length and of preliminary nature,
Professional Papers - articles offering experience useful for the improvement of professional practice i.e. article describing methods and techniques, software, presenting observational data, etc.
In some cases the journal may publish other contributions, such as In Memoriam notes, Obituaries, Book Reviews, as well as Editorials, Addenda, Errata, Corrigenda, Retraction notes, etc.
