... 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 .

Tracking Time (h:mm) . ... The inclusion of the 305-m Arecibo radio telescope can dramatically boost the sensitivity of VLBI observations, even with its limited source tracking...

Research on black holes . ... By allowing scientists to peer into the highly energetic centers of galaxies, Hubble continues to make ground-breaking contributions in the study of black holes. For several decades scientists have known from observations across the electromagnetic spectrum that some galaxies have extremely active regions in their cores. ... The galaxy has an impressive band of dust, gas, and young stars that crosses the optical image, especially in observations taken by WFPC2. ...

... Following the full moon on Monday, March 24, I was able to make use of a few brief periods totalling about an hour and a half before the Easter weekend to make some 160 galaxy observations at home in Coonabarabran using the 0.41m telescope. ... Because of being on holidays my resources for comparison purpouses were rather limited, and so I had to rely upon amateur contacts in Queensland to verify my memory of this galaxy, and also to obtain visual confirmation of the supernova. ...

The framework for data calibration and analysis of the VLT instrumentation is presented, based on the concepts of a calibration plan, pipeline calibration, quality control, and archiving of calibrated data for a ground-based observatory. ... Quality Control Pipeline provides quality assessment for instrument performance data and observing conditions, and tests the results of the Reduction Pipeline. ...

... We have observed and studied critical supercurrents, Ic, in cross-type Nb-Cu/Ni-Nb junctions with Josephson layers prepared from diluted ferromagnetic alloys. For suitable values of the exchange energy in the ferromagnet and the F-layer thickness we have observed Ic(T) oscillation with vanishing Ic for the definite values of T and dF. ... Critical supercurrents, Ic, in Nb-Cu(1-x)Ni(x)-Nb Josephson SFS junctions with F-layers prepared from ferromagnetic Cu(1-x)Ni(x) alloys have been studied. ...

This astrostatistics session will honor the memory of Alanna Connors. Alanna was a pioneer in the investigation and development of statistical methods required for the analysis of high energy data.

The objectives of the present study is to provide a better physical understanding of the complex interrelation and evolution of several solar coronal features comprising a double-peak flare, a coronal dimming caused by a Coronal Mass Ejection (CME), a CME-driven compression, and a fast-mode...

Abstract -- Calculations are performed for the linear polarization of starlight due to extinction by aligned dust grains when the starlight traverses a medium with irregular magnetic fields. This medium is intended to represent the optically thick components of interstellar clouds which are observed to make little, if any, contribution to the polarization of starlight. ...

This means that galaxies are surrounded by dark matter halos which trapped baryonic gas (e.g. hydrogen) and turned it into stars. ...
