In the (logR_e_, μ_e_) plane defined by the logarithm of the effective radius and the effective surface brightness, elliptical galaxies that are members of...

Multi-object spectroscopic observations of A1758N were carried out at the TNG, a 4m-class telescope, in May 2008 and May 2009. We used DOLORES/MOS with the LR-B...

SDSS and 2MASS photometry of 129 ultra-cool dwarf candidates. The photometric data are from the seventh Data Release of the SDSS Photometric and the 2MASS All...

We have completely mapped the Galactic globular cluster NGC 1851 with large-field, ground-based VI CCD photometry and pre-repair HST/WFPC1 data for the central...

Targets were selected from existing V- and I-band photometry obtained as part of the ongoing ARAUCARIA Cepheid search project whose results have been reported...

As early as 10 Gyr ago, galaxies with more than 1011 M ☉ of stars already existed. While most of these massive galaxies must have subsequently transformed...

We present the near infrared photometry of a new sample of 225 IRAS sources, many of them previously unidentified in the literature, selected because their far...

Context. About 20% of low-redshift galaxies are late-type spirals with a small or no bulge component. Although they are the simplest disk galaxies in terms of...

We present high-resolution near-infrared imaging obtained using adaptive optics and HST/NICMOS, and ground-based spectroscopy of the hotspot galaxy NGC 2903...
