Spectral analyses of 16 DAO white dwarfs from the Sloan Digital Sky Survey
S. D. Huegelmeyer, S. Dreizler, T. Rauch +1
We present a spectral analysis of 16 DAO white dwarfs from the Sloan Digital Sky Survey Data Release 4. With our NLTE H+He model grid, we derived photospheric parameters for these…
Quiet Sun magnetic fields from simultaneous inversions of visible and infrared spectropolarimetric observations
Itahiza Dominguez Cerdena, Jorge Sanchez Almeida, Franz Kneer
We study the quiet Sun magnetic fields using spectropolarimetric observations of the infrared and visible Fe I lines at 6301.5, 6302.5, 15648 and 15653 A. Magnetic field strengths…
Dark matter density profiles: A comparison of nonextensive theory with N-body simulations
T. Kronberger, M. P. Leubner, E. van Kampen
Density profiles of simulated galaxy cluster-sized dark matter haloes are analysed in the context of a recently introduced nonextensive theory of dark matter and gas density distri…
Internal kinematics of modelled interacting disc galaxies
T. Kronberger, W. Kapferer, S. Schindler +3
We present an investigation of galaxy-galaxy interactions and their effects on the velocity fields of disc galaxies in combined N-body/hydrodynamic simulations, which include cooli…
Luminous Compact Blue Galaxies up to z~1 in the HST Ultra Deep Field: I. Small galaxies, or blue centers of massive disks?
K. G. Noeske, D. C. Koo, A. C. Phillips +4
We analyze 26 Luminous Compact Blue Galaxies (LCBGs) in the HST/ACS Ultra Deep Field (UDF) at z ~ 0.2-1.3, to determine whether these are truly small galaxies, or rather bright cen…
