High - resolution radio observations of RCW 49
High-resolution radio continuum observations of the southern H II complex RCW 49 are presented. The observations were carried out with the Molonglo Observatory Synthesis Telescope (MOST) at 0.843 GHz, and the Australia Telescope Compact Array (ATCA) at 1.38 and 2.38 GHz. Two wind-blown shells have been discovered in the core region of RCW 49, the more massive of which surrounds the Westerlund 2...
متن کاملNature as a Source of Inspiration of Architectural Conceptual Design
From the beginning of creation, human being was surrounded by nature. Everything in nature is well organized and in harmony with the other parts of it. Through the history, nature has been always a source of inspiration for the human begin in different aspects of their life. Architecture as one of the remarkable features in every society cannot be separated from nature. In architecture design...
متن کاملThe Nature of the Faint Radio Population
We present the results obtained so far from the optical follow-up of the ATESP sub-mJy radio survey. The ATESP results are then compared with the ones obtained from other deep radio samples and we show how the existing discrepancies about the nature of the faint radio population can be explained in terms of selection effects.
متن کاملOn the Nature of Pulsar Radio Emission
A theory of pulsar radio emission generation, in which the observed waves are produced directly by maser-type plasma instabilities operating at the anomalous cyclotron-Cherenkov resonance ω − k‖v‖ + ωB/ γres = 0 and the Cherenkov-drift resonance ω − k‖v‖ − k⊥ud = 0, is capable of explaining the main observational characteristics of pulsar radio emission. The instabilities are due to the interac...
متن کاملW 49 A North - Global or Local or No Collapse ?
We attempt to fit observations with 5 resolution of the J=2−1 transition of CS in the directions of H ii regions A, B, and G of W49A North as well as observations with 20 resolution of the J=2−1, 3−2, 5−4, and 7−6 transitions in the directions of H ii regions A and G by using radiative transfer calculations. These calculations predict the intensity profiles resulting from several spherical clou...
