The molecular outflows in NGC 1333
We present the results of CO(J =3→2) mapping using the James Clerk Maxwell Telescope of the active star formation region NGC 1333, supplemented by CO(J=1→0) mapping from the Onsala Space Observatory millimetre telescope. These maps provide a detailed overview of the complex cluster of overlapping molecular outflows associated with Herbig-Haro (HH) objects and shocked H2, and the far-infrared an...
متن کاملCarma Observations of Protostellar Outflows in Ngc 1333
We present observations of outflows in the star-forming region NGC 1333 using the Combined Array for Research in Millimeter-Wave Astronomy (CARMA). We combined the CO and CO (10) CARMA mosaics with data from the 14-m Five College Radio Astronomy Observatory (FCRAO) to probe the central, most dense and active region of this protostellar cluster at scales from 5′′ to 7′ (or 1000 AU to 0.5 pc at a...
متن کاملA Large Scale Survey of NGC 1333 Andrew
We observed the clustered star forming complex NGC1333 with the BIMA and FCRAO telescopes in the transitions HCO(1–0) and N2H (1–0) over an 11 × 11 area with resolution ∼ 10 (0.015 pc). The N2H emission follows very closely the submillimeter dust continuum emission, while HCO emission appears more spatially extended and also traces outflows. We have identified 93 N2H + cores using the CLUMPFIND...

اندیشمندان و صاحب نظران علوم اجتماعی بر این باورند که مرحله تازه ای در تاریخ جوامع بشری اغاز شده است. ویژگیهای این جامعه نو را می توان پدیده هایی از جمله اقتصاد اطلاعاتی جهانی ، هندسه متغیر شبکه ای، فرهنگ مجاز واقعی ، توسعه حیرت انگیز فناوری های دیجیتال، خدمات پیوسته و نیز فشردگی زمان و مکان برشمرد. از سوی دیگر قدرت به عنوان موضوع اصلی علم سیاست جایگاه مهمی در روابط انسانی دارد، قدرت و بازتولید...
15 صفحه اولTurbulence Driven by Outflow - Blown Cavities in the Molecular Cloud of Ngc 1333
Outflows from young stellar objects have been identified as a possible source of turbulence in molecular clouds. To investigate the relationship between outflows, cloud dynamics and turbulence, we compare the kinematics of the molecular gas associated with NGC 1333, traced in CO(1-0), with the distribution of young stellar objects (YSOs) within. We find a velocity dispersion of ∼ 1− 1.6km/s in ...
