The Qso Variability-luminosity-redshift Relation
The relationship between variability, luminosity and redshift in the South Galactic Pole QSO sample is examined in an eeort to disentangle the eeects of luminosity and redshift in the amplitude of the optical variations. The anticorrelation between variability and luminosity found by other authors is connrmed. Our analysis also supports claims that variability increases with redshift, most like...
متن کاملAutoob Redshift Survey: I { Evolution of the Galaxy Luminosity Function
We present a detailed determination of the restframe B-band galaxy luminosity function (LF) as a function of redshift and star formation activity from z=0 to z '0.75. The dataset used for this purpose is a combined sample of over 1700 redshifts spanning a wide range in apparent magnitude, 11.5< b J <24.0, which we term the Autoob Redshift Survey. The sample includes various earlier magnitude-li...
متن کاملSolitons in Brane Worlds
We study some aspects of dilatonic domain walls in relation to the idea on the noncompact internal space. We find that the warp factor in the spacetime metric increases as one moves away from the domain wall for all the supersymmetric dilatonic domain wall solutions obtained from the (intersecting) BPS branes in string theories through toroidal compactifications, unlike the case of the Randall-...
متن کاملBrane worlds in collision.
We obtain an exact solution of the supergravity equations of motion in which the four-dimensional observed Universe is one of a number of colliding D3 branes in a Calabi-Yau background. The collision results in the ten-dimensional spacetime splitting into disconnected regions, bounded by curvature singularities. However, near the D3 branes the metric remains static during and after the collisio...
متن کاملSolitons in Brane Worlds II
We study the solution describing a non-extreme dilatonic (p+1)-brane intersecting a D-dimensional extreme dilatonic domain wall, where one of its longitudinal directions is along the direction transverse to the domain wall, in relation to the Randall-Sundrum type model. The dynamics of the probe (p + 1)-brane in such source background reproduces that of the probe p-brane in the background of th...
