Surface spots on cool giant stars probed by spectro-astrometry
(Univ. Hamburg, 2009)
Spectro-astrometry is a technique to obtain information about the structure of an astronomical source on sub-diffraction limited spatial scales down to milli- or micro-arcseconds. The method exploits the shift of the ...
Search for neutrino induced cascades with 5 years of the AMANDA-II data
(Univ. Berlin, 2008)
Das Antarctic Muon And Neutrino Detector Array (AMANDA) ist ein Cherenkov Detektor, der sich im Gletscher der Antarktis am Südpol befindet. Wir präsentieren die Analyse von Daten, die in den Jahren 2000 bis 2004 gesammelt ...
Chiral symmetry restoration and deconfinement in neutron stars
(Univ. Frankfurt (Main), 2009)
Neutron stars are very dense objects. One teaspoon of their material would have a mass of five billion tons. Their gravitational force is so strong that if an object were to fall from just one meter high it would hit the ...
The Yığma Tepe of Pergamon: Internal construction of a monumental burial mound from shear wave reflection sounding and wavefield modelling
(
- Archaeological Prospection
, 2021-01-27)
The Yığma Tepe of Pergamon is one of the largest known burial mounds in the Eastern Mediterranean. Its internal structure, especially the existence and location of burials, remains unknown so far because its height of 32 ...
Improving crosshole ground‐penetrating radar full‐waveform inversion results by using progressively expanded bandwidths of the data
(
- Near Surface Geophysics
, 2021-05-05)
In the last decade, time‐domain crosshole ground‐penetrating radar full‐waveform inversion has been applied to several different test sites and has improved the resolution and reconstruction of subsurface properties. The ...
Zur Ermittlung geophysikalischer Massensignale mit Schwerefeldmissionen
(Univ. Dresden, 2007)
Die neuen Schwerefeld-Satellitenmissionen CHAMP (Challenging Minisatellite Payload), GRACE (Gravity Recovery and Climate Experiment) und GOCE (Gravity Field and Steady-State Ocean Circulation Explorer) können wesentlich ...
CRS-stack-based seismic reflection imaging for land data in time and depth domains
(Univ. Karlsruhe, 2007)
Land data acquisition often suffers from rough top-surface topography and complicated near-surface conditions. The resulting poor data quality makes conventional data processing very difficult. Under such circumstances, ...
Einfluss der Variationen atmosphärischer Größen und der Ionisation auf mesosphärische Radarechos in polaren und mittleren Breiten
(Univ. Rostock, 2008)
Diese Arbeit konzentriert sich auf den Einfluss der Variationen atmosphärischer Größen und der Ionisation auf Radarechos in der Mesosphäre. Die Messungen wurden mit VHF-Radars (53,5 MHz) in Kühlungsborn (54ʿN) und Andenes ...
Untersuchung der Lithosphäre des Dronning Maud Lands, Antarktis, mit geophysikalischen Methoden

Antarctica, Dronning Maud Land, anisotropy, seismic anisotropy, shear wave splitting, receiver functions, moho, moho depth, crust, upper mantle, refraction seismic, gravity, 3D-gravity, igmas, bouguer anomaly, seismology. ...
Thermo-hydraulic conditions in a seismically active zone (Gulf of Corinth, Greece)
(Univ. Karlsruhe, 2007)
In this thesis the thermo-hydraulic conditions of a seismically active zone have been investigated by means of surface and subsurface investigations, borehole studies and numerical modeling. European research activities ...
