На протяжении последних нескольких лет в рамках проекта MACHO проводятся наблюдения микролинзирования звезд Большого Магелланова Облака - спутника нашей Галактики. Эффект микролинзирования заключается в гравитационной фокусировке света звезды массивным объектом, находящимся на луче зрения между звездой и наблюдателем. ... Согласно некоторым гипотезам, линзами могут являться реликтовые черные дыры или "нейтралинные звезды". ...

The parameter compactness is set to C or D if respectively a galaxy was reported as beeing "compact" or "diffuse" in the litterature or in catalogues. This parameter has been determine for only a fraction of the galaxies in the database and therefore the absence of compactness does not indicate that a galaxy is neither "compact" nor "diffuse". There are 4874 galaxies with compactness=D and 4304 with compactness=C in the database (May 2003 version). HyperLeda . Questions: prugniel@obs.univ-lyon1.fr

Figure: The dependence of different compact binary merging rates in a model ``elliptical'' galaxy (where all the stars were formed simultaneously at the moment t =0) with mass M . The horizontal line shows the mean merging rate of binary NS in a spiral galaxy of the same mass with a stationary star formation. ...

We present far-infrared spectra, ЮЛ = 52-93 ЮМm, obtained with the Spitzer Space Telescope in the spectral energy distribution mode of its Multiband Imaging Photometer for Spitzer instrument, of a selection of luminous compact far-infrared sources in the Small Magellanic Cloud (SMC). ...

... The Workshop is dedicated to QCD Phase Transitions and observational signals of these Transitions related to formation of compact astrophysical objects. The aim of this workshop is to bring together researchers working on the problems of the behavior and observability of matter under critical conditions achievable in such astrophysical objects as 'strange' or 'hybrid' stars and in laboratories at heavy-ion collisions to discuss fundamental issues and recent developments. ...
