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
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...
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...
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...
