Seit in der Milchstrase ein supermassereiches Schwarzes Loch entdeckt wurde, haben Astronomen solche Objekte in fast allen aktiven Galaxien aufgespurt. Heute erforschen sie, wie stark die Gravitationsmonster Entstehung und Schicksal ihrer Galaxien be

In cosmology the peculiar situation arises that all the parameters of a standard cosmological model are precisely measured, whereas within the context of this model 95 % of the cosmic matter and energy density are unknown quantities: 27 % are account

We investigate the influence of radiative effects on supersonic wind accretion onto gravitating objects. The accreting matter is assumed to be optically thin. The physical mechanisms taken into account include cooling due to free-free and free-bound

Beobachtungen der Ausdehnung des Weltalls und der Temperaturschwankungen der kosmischen Hintergrundstrahlung fuhren zu einer prazisen Bestimmung aller kosmischen Parameter. Das uberraschende Ergebnis ist, dass die kosmische Expansion gegenwartig besc

In a detailed analysis of the three-point correlation function (3PCF) for the 2dF Galaxy Redshift Survey (2dFGRS), we have accurately measured the 3PCF for galaxies of different luminosities. The 3PCF amplitudes [Q(red) (s, u, v) or Q(proj)(r(p), u,v

Connections developed in recent years between particle physics and cosmologyare the focus of attention in this new textbook. The author describes some of the theories which have been developed to describe the fundamental interaction of elementary par

We present velocity statistics of galaxies and their biases inferred from the statistics of the underlying dark matter using a cosmological hydrodynamic simulation of galaxy formation in low-density and spatially flat cold dark matter cosmogony. We f

We use N-body simulations to test the predictions of the redshift distortion in the power spectrum given by the halo model in which the clustering of dark matter particles is considered as a result both of the clustering of dark halos in space and of

Die kosmische Hintergrundstrahlung ist ein Stutzpfeiler des kosmischen Urknallmodells. Aus kleinen raumlichen Temperaturschwankungen in diesem Strahlungsfeld, die in den letzten Jahren durch zwei Ballonexperimente genauer vermessen wurden, lassen sic
