Spectropolarimetry of Compton-thin Seyfert 2s
S. L. Lumsden, D. M. Alexander, J. H. Hough
We present new spectropolarimetry of a sample of nearby Compton-thin Seyfert 2 galaxies (ie those with N_H<10^23 cm^-2). We show that the detection rate of scattered broad Halpha i…
Direct Observation of a Temperature Dependent 0-pi Junction Transition in a Mesoscopic High Critical Temperature Grain Boundary Junction
G. Testa, A. Monaco, E. Esposito +5
We have observed, for the first time, a temperature dependent 0-pi junction crossover in a 45 symmetric [001] tilt grain boundary junction. Experimental data, obtained by a double…
Properties of QSO Metal Line Absorption Systems at High Redshifts: Nature and Evolution of the Absorbers and the Ionizing Radiation Background
Alec Boksenberg, Wallace L. W. Sargent, Michael Rauch
In Keck HIRES spectra of 9 QSOs we identify a sample of 908 CIV absorber components in 188 systems outside the Lyman forest in the redshift range 1.6 < z < 4.4, with related lines…
Mixing and the s-process in rotating AGB stars
Falk Herwig, Norbert Langer, Maria Lugaro
We model the nucleosynthesis during a radiative interpulse phase of a rotating 3Msun Asymptotic Giant Branch (AGB) star. We find an enhanced production of the neutron source specie…
