We present an XMM-Newton observation of NGC 7469, including studies of the X-ray and UV variability, 0.2−10 keV spectral continuum, Fe Kα emission line and the first-ever high-resolution X-ray spectrum of the soft X-ray warm absorber. We compare the properties of this X-ray warm absorber with the UV warm absorber as seen in a FUSE observation one year previously. The 0.2−10 keV spectral continu...

The dependence of the shape of the glow curve of LiF:Mg,Ti (TLD-100) on ionisation density was investigated using irradiation with (90)Sr/(90)Y beta rays, 60 and 250 kVp X rays, various heavy-charged particles and 0.2 and 14 MeV neutrons. Special attention is focused on the properties of high-temperature thermoluminescence; specifically, the behaviour of the high-temperature ratio (HTR) of Peak...

Context. The investigation of the dominant formation mechanism of early-type galaxies. Aims. In this work we derive clues to the formation scenario and ionisation source of the lenticular galaxy NGC3607 by means of metallicity gradients, stellar population and emission lines properties. Methods. We work with long-slit spectroscopy from which we (i) study the radial distribution of the equivalen...

Characterising the protein signatures in tumours following vascular-targeted therapy will help determine both treatment response and resistance mechanisms. Here, mass spectrometry imaging and MS/MS with and without ion mobility separation have been used for this purpose in a mouse fibrosarcoma model following treatment with the tubulin-binding tumour vascular disrupting agent, combretastatin A-...

The difference in the relative biological efficiency (RBE) of ions of same linear energy transfer (LET) but different atomic number (Z) can be attributed to the difference in the radial ionisation distribution. We have performed systematic measurements of the spatial ionisation pattern of heavy ions of various Z but similar LET at GSI. The results are compared with track structure data obtained...

Aims. The present paper addresses some of the problems in the buildup of element stratification in stellar magnetic atmospheres due to microscopic diffusion, in particular the redistribution of momentum among the various ionisation stages of a given element and the calculation of diffusion velocities in the presence of inclined magnetic fields. Methods. We have considerably modified and extende...

We present a procedure, based on established principles, to accurately determine the ionisation energies of medium-sized large polyatomic molecules in supersonic beams. The method combines single-photon excitation from electronic ground state using tunable vacuum-ultraviolet laser radiation, delayed pulsed-field high Rydberg states with sequences pulsed electric fields, and modelling lineshapes...
