XMM-Newton observation of Mrk 110
Th. Boller, I. Balestra, W. Kollatschny
We report on the first XMM-Newton observation of the bright Narrow-Line Seyfert 1 galaxy Mrk 110. We find a narrow Fe K fluorescent line, a broad component FWHM ~ 16500 km/s of the…
Properties of Young Massive Cluster Derived from Photometry
U. Fritze-v. Alvensleben
I will show that photometry -- if extending over a reasonable choice of passbands -- can give fairly precise information about young star clusters and their evolutionary state. Opt…
Star Formation in Galaxy Mergers: Scaling up a universal process or a violent mode of SF?
U. Fritze-v. Alvensleben
I briefly review some measures of star formation rates in galaxies and discuss their respective uncertainties before outlining the range of star formation rates encountered in star…
HS2237+8154: On the onset of mass transfer or entering the period gap?
B. T. Gaensicke, S. Araujo-Betancor, H. -J. Hagen +4
We report follow-up observations of a new white dwarf/red dwarf binary HS2237+8154, identified as a blue variable star from the Hamburg Quasar Survey. Ellipsoidal modulation observ…
Evolution of the polarization of the optical afterglow of the gamma-ray burst GRB 030329
J. Greiner, S. Klose, K. Reinsch +23
We report 31 polarimetric observations of the afterglow of GRB 030329 with high signal-to-noise and high sampling frequency. We establish the polarization light curve, detect susta…
Globular Cluster Populations: Signatures and Implications
Uta Fritze-v. Alvensleben, Richard de Grijs
The formation of populous secondary star cluster systems is a widespread phenomenon in mergers of gas-rich galaxies. Many, if not most, of those clusters are massive and compact en…
