摘要:We present first results of an implementation of chemical evolution in a cosmological hydrodynamical code, focusing the analysis on the effects of cooling baryons according to their metallicity. We found that simulations with primordial cooling can underestimate the star for...

摘要:We present the results of a study of the average mass profile around galaxies using weak gravitational lensing. We use 45.5 deg2 of RC band imaging data from the Red-Sequence Cluster Survey (RCS) and define a sample of ~ 1.2 × 105 lenses with...

摘要:Our recent Chandra and XMM-Newton observations of the gravitationally lensed broad absorption line quasars (BALQSOs) APM 08279+5255 and PG 1115+080 have provided new insights into the structure of quasar outflows and the enrichment of their host galaxies by quasar winds (Chartas ...

摘要:High resolution spatial scans through the planetary nebula BD +30°3639 have been made with the UCL cooled grating spectrometer at the IRTF. A spectral resolution of λ/Δλ = 50 was sufficient to resolve the unidentified dust features at 8.6 and 11.3 μm and separate them f...

摘要:Superwind galaxies at high-redshift are now considered to be the important clue for understanding the interaction and evolution of both galaxies and intergalactic matter. In order to improve our knowledge of superwind galaxies at high redshift, a large sample of superwind candida...

摘要:The characteristics of stars of very low mass are reviewed with emphasis on signatures of and consequences of magnetic activity.

摘要:We present new spectroscopic observations of WC9 stars. As predicted by Williams & van der Hucht (2000), O ii lines are weak in the dust-free star WR88, which also shows a high ionization. Spectral variability is detected in WR 106 and WR 121. These findings are briefly discussed...

摘要:As was pointed out by IAU in 1976, an important problem in fundamental astronomy is the improvement of the vernal equinox and equator positions. To this aim, it is necessary to know the accurate values of minor planets orbital elements. The classical methods of orbital elements d...
