We present metallicities and their variations with different parameters for 36 high-latitude fields covering Galactic longitudes 0° l ⩽ 360°. The metallicities for relatively short vertical distances (z 2.5 kpc) show systematic fluctuations with Galactic longitude, similar to those of the thick-disc scaleheight, which may be interpreted as

We present mid-infrared data of a sample of 57 AGNs obtained with the instrument ISOCAM on board the Infrared Space Observatory (ISO) satellite. The images were obtained through the LW2 (6.75 μm) and LW7 (9.62 μm) filters. This is a new analysis of the Clavel et al. galaxy sample, which is divided into 26 type 1 (1.5) Seyfert galaxies, plus three

We measure the Milky Way's rotation curve over the Galactocentric range 4 kpc

According to LCDM theory, hierarchical evolution occurs on all mass scales, implying that satellites of the Milky Way should also have companions. The recent discovery of ultra-faint dwarf galaxy candidates in close proximity to the Magellanic Clouds provides an opportunity to test this theory. We present proper motion (PM) measurements for 13 of

The bulge of the Galaxy is analyzed by inverting K-band star counts from the Two-Micron Galactic Survey in a number of off-plane regions. A total area of about 75 sq deg of sky is analyzed. Assuming a nonvariable luminosity function within the bulge, we derive the top end of the K-band luminosity function and the stellar density function, whose

We investigate the morphologies, masses and possible correlations between these two properties for 108 extremely red galaxies (EROs) found in the Groth strip. The photometric data include U, B, F606W, F814W, J, and K_s bands. The EROs were selected on the basis of their extremely red colour, F814W-K_s ≥ 4 and K_s ≤ 21.0. Morphologies are based on a
