... A2268 Date Received: 2006 -Oct-02 15:19:03 Technical Page Proposal Type: General Category: Sub-Category: Observation Category: Total Time Requested: Minimum Useful Time: Prop osal Title: ABSTRACT: We propose using 6 hours of Arecibo time to measure the synchrotron contribution to the submillimeter (submm) emission of galaxies in the SCUBA Local Universe Galaxy Survey. ... However, the submm flux may not be solely due to dust but may also include CO (3-2) and continuum synchrotron emission. ...

... Programme . ... Abstract: We successfully resolved the dust lane of Centaurus A (NGC 5128), that is the nearest radio galaxy ( D = 3.4 Mpc), at an angular resolution of 24 arcsec (400 pc) by observing the CO ( J = 3 2) emission with the sub-mm telescope ASTE. ... Since our results showed kinematics of the dust warped disk, we will discuss kinematics and physical properties in the dust lane of Centaurus A. go back .

... A radio galaxy is a galaxy that emits an unusually big amount of energy at radio wavelengths. ... Inside of each galaxy with an active nucleus (radio galaxies are among them) there must be a system of a "central machine" responsible for the colossal amount of the emitted energy from radio to gamma ranges. ... Sometimes a radio source in an active galaxy may flare again if the needed conditions appear (a new portion of matter would fall into the furnace of the "central machine"). ...

... Previous: Substepping and its Application to HST Imaging . ... This is a preliminary report on an application of the co-addition technique based upon the Richardson-Lucy algorithm. The combination of high signal-to-noise ground-based images obtained with the ESO NTT using SUSI with high angular resolution HST FOC f/96 images gives new insights on the properties of galaxy cores and their potential time variability. Cores of galaxies are one of the main thrusts of present extragalactic research. ...

... Line radiative transfer in C 18 O, HCO + , and CS lines is considered in a spherically symmetric chemo-dynamical model of a starless core, evolution of which is driven by the ambipolar diffusion. Theoretical line profiles are compared to observational data on the well-known L1544 core, which is one of possible candidates for collapsing protostellar clouds. ... Comparison between modelled and observed spectra suggests that L1544 has flattened structure and is observed at some inclination. ...
