The M31 microlensing event WeCAPP-GL1/Point-AGAPE-S3: evidence for a MACHO component in the dark halo of M31?
A. Riffeser, S. Seitz, R. Bender
We re-analyze the M31 microlensing event WeCAPP-GL1/Point-AGAPE-S3 taking into account that stars are not point-like but extended. We show that the finite size of stars can dramati…
X-ray monitoring of optical novae in M31 from July 2004 to February 2005
W. Pietsch, F. Haberl, G. Sala +9
Optical novae have recently been identified as the major class of supersoft X-ray sources in M31 based on ROSAT and early XMM-Newton and Chandra observations. This paper reports on…
The sizes of galaxy halos in galaxy cluster Abell 1689
A. Halkola, S. Seitz, M. Pannella
The multiple images observed in galaxy cluster Abell 1689 provide strong constraints not only on the mass distribution of the cluster but also on the ensemble properties of the clu…
Lyman Break Galaxies Under a Microscope: The Small Scale Dynamics and Mass of an Arc in the Cluster 1E0657-56
N. P. H. Nesvadba, M. D. Lehnert, F. Eisenhauer +8
Using the near-infrared integral-field spectrograph SPIFFI on the VLT, we have studied the spatially-resolved dynamics in the z=3.2 strongly lensed galaxy 1E0657-56 ``arc+core''. T…
Parametric Strong Gravitational Lensing Analysis of Abell 1689
A. Halkola, S. Seitz, M. Pannella
(Abridged) We measure the mass distribution of galaxy cluster Abell 1689 within 0.3 Mpc/h_70 of the cluster centre using its strong lensing effect on 32 background galaxies. The mu…
Lyman-alpha emission galaxies at a redshift of z = 5.7 in the FORS Deep Field
C. Tapken, I. Appenzeller, A. Gabasch +7
We present the results of a search for Lyman-alpha emission galaxies at z~ 5.7 in the FORS Deep Field. The objective of this study is to improve the faint end of the luminosity fun…
