ThisvolumecontainsselectedlecturespresentedattheSpanishRelativityMe- ingonRelativisticAstrophysicsheldattheEscuelaT ́ecnicaSuperiordeIn- nierosNavalesofMadrid,Spain,inSeptember2001. The meeting centered on the study of several aspects of Relativistic - trophysics from various viewpoints: theoretical, numerical and observational. Lectures and contributions dealt with issues related to black holes (accretion, thermodynamics, gravitational collapse, stability), numerical and perturbative aspects of astrophysical processes (black hole evolution, relativistic stars, jet hydrodynamics. . . )andproductionanddetectionofgravitationalwaves. Other topicsandanimationsareenclosedintheaccompanyingCD-ROM. Lecturesandcontributionsareintendedtocoverthegapbetweenundergr- uatecoursesandcurrentresearchinthe?eld,includingthemostrecentadvances inRelativisticAstrophysics.
