Measuring and calibrating Galactic synchrotron emission

Our position inside the Galaxy requires all-sky surveys to reveal its large-scale properties. The zero-level calibration of all-sky surveys differs from standard 'relative' measurements, where a source is measured in respect to its surroundings. All-sky surveys aim to include emission structures of all angular scales exceeding their angular resolution including isotropic emission components. Synchrotron radiation is the dominating emission process in the Galaxy up to frequencies of a few GHz, where numerous ground based surveys of the total intensity up to 1.4 GHz exist. Its polarization properties were just recently mapped for the entire sky at 1.4 GHz. All-sky total intensity and linear polarization maps from WMAP for frequencies of 23 GHz and higher became available and complement existing sky maps. Galactic plane surveys have higher angular resolution using large single-dish or synthesis telescopes. Polarized diffuse emission shows structures with no relation to total intensity emission resulting from Faraday rotation effects in the interstellar medium. The interpretation of these polarization structures critically depends on a correct setting of the absolute zero-level in Stokes U and Q.Comment: 10 pages, 8 figures.

Gymnasia in Eastern Sicily of the Hellenistic and Roman Period

Schriftquellen und Inschriften legen nahe, dass in Sizilien die Institution des Gymnasions vom 3. Jh. v. Chr. an florierte, im Reich Hierons II. wie auch in der spätrepublikanischen römischen Provinz. Dieser Beitrag untersucht kritisch, ob sich dieser Boom im archäologischen Befund und in der Entstehung einer eindeutig erkennbaren Bautypologie widerspiegelt. Am Beispiel von fünf ostsizilischen Städten in Hierons Reich (Syrakus, Morgantina, Megara Hyblaea, Neaiton, Akrai) wird untersucht, ob Gymnasia sicher identifiziert werden können, welchen Grundriss sowie welche Ausstattung und Funktion sie hatten, und ob es Änderungen zwischen dem 3. Jh. und späteren Epochen gab. Es wird gezeigt, dass bislang keine dieser Städte ein sicher identifiziertes und vollständig bekanntes Gymnasium aufweist

Full Sky Study of Diffuse Galactic Emission at Decimeter Wavelengths

A detailed knowledge of the Galactic radio continuum is of high interest for studies of the dynamics and structure of the Galaxy as well as for the problem of foreground removal in Cosmic Microwave Background measurements. In this work we present a full-sky study of the diffuse Galactic emission at frequencies of few GHz, where synchrotron radiation is by far the dominant component. We perform a detailed combined analysis of the extended surveys at 408, 1420 and 2326 MHz (by Haslam et al. 1982, Reich 1982, Reich & Reich, 1986 and Jonas et al. 1998, respectively). Using the technique applied by Schlegel et al. (1998) to the IRAS data, we produce destriped versions of the three maps. This allows us to construct a nearly-full-sky map of the spectral index and of the normalization factor with sub-degree angular resolution. The resulting distribution of the spectral indices has an average of beta = 2.695 and dispersion sigma_{beta} = 0.120. This is representative for the Galactic diffuse synchrotron emission, with only minor effects from free-free emission and point sources.Comment: 10 pages, 16 jpeg figures, accepted to Astronomy & Astrophysics, Comments and figure adde
