ImpZ: a new photometric redshift code for galaxies and quasars
T. S. R Babbedge, M. Rowan-Robinson, E. Gonzalez-Solares +7
We present a combined galaxy-quasar approach to template-fitting photometric redshift techniques and show the method to be a powerful one. The code (ImpZ) is presented, developed a…
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…
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…
Could SiC A+B grains have originated in a post-AGB thermal pulse?
Falk Herwig, Sachiko Amari, Maria Lugaro +1
The carbon and nitrogen isotopic ratios of pre-solar SiC grains of type A+B suggest a proton-limited nucleosynthetic process as encountered, for instance, during the very late ther…
Oscillation power across the HR diagram : sensitivity to the convection treatment
Reza Samadi, Guenter Houdek, Marie-Jo Goupil +2
Solar-like oscillations are stochastically excited by turbulent convection. In this work we investigate changes in the acoustic oscillation power spectrum of solar-type stars by va…
