Chemical composition of 90 F and G disk dwarfs
Y. Q. Chen, P. E. Nissen, G. Zhao +2
High resolution, high S/N spectra have been obtained for a sample of 90 F and G main-sequence disk stars covering the metallicity range -1.0 < [Fe/H] < +0.1, and have been analysed…
Finding typical high redshift galaxies with the NOT
J. U. Fynbo, P. Moller, B. Thomsen
We present results from an ongoing search for galaxy counterparts of a subgroup of Quasar Absorption Line Systems called Damped Ly-alpha Absorbers (DLAs). DLAs have several charact…
Sc and Mn abundances in disk and metal-rich halo stars
P. E. Nissen, Y. Q. Chen, W. J. Schuster +1
Sc and Mn abundances are determined for 119 F and G main-sequence stars with -1.4 < [Fe/H] < +0.1, representing stars from the thin disk, the thick disk and the halo. The results i…
The Gas Reservoir for present day Galaxies : Damped Ly-alpha Absorption Systems
J. U. Fynbo, B. Thomsen, P. Moller
We present results from an ongoing search for galaxy counterparts of a subgroup of Quasar Absorption Line Systems called Damped Ly-alpha Absorbers (DLAs). DLAs have several charact…
Probing strange stars and color superconductivity by r-mode instabilities in millisecond pulsars
Jes Madsen
R-mode instabilities in rapidly rotating quark matter stars (strange stars) lead to specific signatures in the evolution of pulsars with periods below 2.5 msec, and may explain the…
Stochastic optimization methods for extracting cosmological parameters from CMBR power spectra
Steen Hannestad
The reconstruction of the CMBR power spectrum from a map represents a major computational challenge to which much effort has been applied. However, once the power spectrum has been…
