Report by the ESA-ESO Working Group on Fundamental Cosmology Abstract In September 2003, the executives of ESO and ESA agreed to establish a number of working groups to explore possible synergies between these two major European astronomical institutions on key scientific issues. The first two working group reports (on Extrasolar Planets and the HerschelнALMA Synergies) were released in 2005 and 2006, and this third report covers the area of Fundamental Cosmology. The Working Group's mandate was to

ПОЧЕМУ МАРС? ... В космическом центре JPL (США) построена модель гравитационного поля Марса, «Mars 50с», в которой разложение гравитационного потенциала планеты по сферическим функциям доведено до 50-ой гармоники [24]. ... В противоположность этому, Марс, начиная с Хесперийской эпохи (1.8 млрд. лет тому назад), стал весьма не похож на Землю, когда скорость процессов эрозии стала очень низкой, и она с тех пор привела к малым изменениям поверхности в месте посадки КА «Марс Пасфайндер». ...

... We show that broadband energy spectra of GRS 1915+105 during all these spectral states can be adequately presented by two bulk motion Comptonization (BMC) components: a hard component (BMC1, photon index 1 = 1.73.0) with turnover at high energies and soft thermal component (BMC2, 2 = 2.74.2) with characteristic color temperature 1 keV, and the redskewed iron-line (LAOR) component. We also present observable correlations between the index and the normalization of the disk "seed" component. ...
