The GeV photon beam at SPring-8 is produced by backward-Compton scattering of laser photons from 8 GeV electrons. Polarization of the photon beam will be ~100% at the maximum energy with fully polarized laser photons. We report the status of the new facility and the prospect of hadron physics study with this high quality beam. Preliminary results from the first physics run are presented.

AbstractThe paper reports the preliminary results from the short season of fieldwork that the Cyrenaican Prehistory Project was able to undertake with a small Anglo-Libyan team in September 2013. The work concentrated on continuing the excavation of Trench M down the southern side of the Middle Trench and of Trench D on the southern side of the Deep Sounding below it, the eventual objective being to link these so as to provide a high quality dataset of sedimentary and cultural data from the top to the bottom of the Pleistocene occupation deposit (some 12 m). The ~1 m of sediments investigated in Trench M in the 2013 fieldwork includes carbonate crusts possibly formed in oscillating sub-humid to arid climatic pulses, perhaps likely during Marine Isotope Stage (MIS) 4, around 60,000–70,000 years ago. One of these crusts formed the base on which a hearth-like structure had been built. In Trench D evidence for human occupation appears to decline moving up the profile, coinciding with sedimentary evidence of more frequent disruptive climatic events possibly associated with latter stages of MIS 5.

Preliminary Results

High quality GPS and differential InSAR data have been collected for determining the ground deformation associated with the September 2010 Darfield (Canterbury) earthquake. We report preliminary results from a subset of these data and derive a preliminary source model for the earthquake. While the majority of moment release in the earthquake occurred on the strike-slip Greendale Fault a number of other fault segments were active during the earthquake including a steeply southeast-dipping thrust fault coincident with the earthquake hypocentre.

Preliminary Results

We report preliminary results from high-resolution UV spectroscopy of the super star cluster 1 in the nearby dwarf starburst galaxy NGC 1705, using HST-stis. These new observations can help us to quantify accurately the stellar content in this super cluster. Together with high quality spectra from SMC stars and the evolutionary synthesis code starburst99, we estimate an age for this cluster of 12±3 Myr, in agreement with previous studies. The measured dynamical mass and the theoretical L/M ratio suggest a normal IMF down to the hydrogen-burning limit.

AbstractThe space astrometry mission Gaia will construct a dense optical QSO-based celestial reference frame. For consistency between the optical and radio positions, it will be important to align the Gaia frame and the International Celestial Reference Frame (ICRF) with the highest accuracy. Currently, it is found that only 10% of the ICRF sources are suitable to establish this link, either because they are not bright enough at optical wavelengths or because they have significant extended radio emission which precludes reaching the highest astrometric accuracy. In order to improve the situation, we have initiated a VLBI survey dedicated to finding additional high-quality radio sources for aligning the two frames. The sample consists of about 450 sources, typically 20 times weaker than the current ICRF sources, which have been selected by cross-correlating optical and radio catalogues. This paper presents the observing strategy and includes preliminary results of observation of 224 of these sources with the European VLBI Network in June 2007.

The importance of coatings in modern science and industry is great, and the system presented in this manuscript attempts to provide a method of creating high quality nanoparticle coatings with in situ sintering of nanoparticles. Dual regime nozzle creates close to optimum conditions for particle delivery and deposition and the addition of in situ thermally assisted coating makes it more productive. Preliminary results show systems uniform coating and in situ sintering capability.

Objective Prism

The unique 70-cm meniscus-type telescope of the Abastumani Astrophysical Observatory supplied with two objective prisms and the seeing conditions characteristic at Mount Kanobili (Abastumani) permit us to obtain stellar spectra of a high quality. No additional design to improve the “climate” immediately around the telescope itself is being applied. The dispersions and photographic magnitude limits are 160 and 660Å/mm, and 12–13, respectively. The short-wave end of spectra reaches 3500–3400Å.

AbstractA widely used tool in studying quasi-monoperiodic processes is the O–C diagram. This paper deals with the application of this diagram in minor planet studies. The main difference between our approach and the classical O–C diagram is that we transform the epoch (=time) dependence into the geocentric longitude domain. We outline a rotation modelling using this modified O–C and illustrate the abilities with detailed error analysis. The primary assumption, that the monotonity and the shape of this diagram is (almost) independent of the geometry of the asteroids is discussed and tested. The monotonity enables an unambiguous distinction between the prograde and retrograde rotation, thus the four-fold (or in some cases the two-fold) ambiguities can be avoided. This turned out to be the main advantage of the O–C examination. As an extension to the theoretical work, we present some preliminary results on 1727 Mette based on new CCD observations.
