From a comparison of the different parameters of warped galaxies in the radio, and especially in the visible, we find that: a) No large galaxy (large mass or...
Was the progenitor of the Sagittarius stream a disc galaxy?
We use N-body simulations to explore the possibility that the Sagittarius (Sgr) dwarf galaxy was originally a late-type, rotating disc galaxy, rather than a non...
Washington photometry of five star clusters in the Large Magellanic Cloud
We present CCD photometry in the Washington-system C and T1 passbands down to T1 ~ 22.5 mag in the fields of NGC 1697, SL 133, NGC 1997, SL 663, and OHSC 28...
Washington photometry of five star clusters in the Large Magellanic Cloud
Aims: We present CCD photometry in the Washington system C and T1 passbands down to T1 ~ 22.5 in the fields of NGC 1697, SL 133, NGC 1997, SL 663, and OHSC 28...
Wavelength-dependent kinematics in the dusty inclined galaxy NGC 2146
We present measurements of the apparent rotation curves of the dusty inclined spiral NGC 2146 taken using conventional long-slit spectroscopy in the red and...
Weak Galactic halo-Fornax dSph connection from RR Lyrae stars
Aims: For the first time accurate pulsation properties of the ancient variable stars of the Fornax dwarf spheroidal galaxy (dSph) are discussed in the broad...
WEAVE-StePS: A stellar population survey using WEAVE at WHT
Context. The upcoming new generation of optical spectrographs on four-meter-class telescopes will provide valuable opportunities for forthcoming galaxy surveys...
WeCAPP - Wendelstein Calar Alto pixellensing project I. Tracing dark and bright matter in M 31
We present WeCAPP, a long term monitoring project searching for microlensing events towards M 31. Since 1997 the bulge of M 31 was monitored in two different...
Observations of M31 were obtained using the 0.8-m telescope at Wendelstein, Germany and the 1.2-m telescope at Calar Alto, Spain, over three observing seasons...
