Testing non-linear force-free coronal magnetic field extrapolations with the Titov-Demoulin equilibrium
Thomas Wiegelmann, Bernd Inhester, Bernhard Kliem +2
CONTEXT: As the coronal magnetic field can usually not be measured directly, it has to be extrapolated from photospheric measurements into the corona. AIMS: We test the quality of…
The 2dF-SDSS LRG and QSO Survey: QSO clustering and the L-z degeneracy
J. da Angela, T. Shanks, S. M. Croom +12
We combine the QSO samples from the 2dF QSO Redshift Survey (2QZ) and the 2dF-SDSS LRG and QSO Survey (2SLAQ) in order to investigate the clustering of z~1.4 QSOs and measure the c…
The XMM-Newton Survey in the Marano Field I. The X-ray data and optical follow-up
M. Krumpe, G. Lamer, A. D. Schwope +6
We report on a medium deep XMM-Newton survey of the Marano Field and optical follow-up observations. The mosaicked XMM-Newton pointings in this optical quasar survey field cover 0.…
Carbon monoxide in the solar atmosphere II. Radiative cooling by CO lines
S. Wedemeyer-Böhm, M. Steffen
The role of carbon monoxide as a cooling agent for the thermal structure of the mid-photospheric to low-chromospheric layers of the solar atmosphere in internetwork regions is inve…
Effect of dark matter annihilation on gas cooling and star formation
Y. Ascasibar
In the current paradigm of cosmic structure formation, dark matter plays a key role on the formation and evolution of galaxies through its gravitational influence. On microscopic s…
An Explanation for the Observed Weak Size Evolution of Disk Galaxies
Rachel S. Somerville, Marco Barden, Hans-Walter Rix +14
Surveys of distant galaxies with the Hubble Space Telescope and from the ground have shown that there is only mild evolution in the relationship between radial size and stellar mas…
