We use Hubble Space Telescope (HST) near-infrared imaging to explore the shapes of the surface brightness profiles of bulges of S0-Sbc galaxies at high...

We present optical and near-infrared colour maps of the central regions of bulges of S0 and spiral galaxies obtained with WFPC2 and NICMOS on the Hubble Space...

We have measured the central structural properties for a sample of S0-Sbc galaxies down to scales of ~10 pc using Hubble Space Telescope NICMOS images. Central...

We investigate bulge and disk scaling relations using a volume-corrected sample of early- to intermediate-type disk galaxies in which, importantly, the biasing...

We study the stellar content of three galactic bulges with the high resolution gratings (R=7000) of the WiFeS integral field unit in order to better understand...

We present detailed spectroscopic analysis of nitrogen abundances in 31 unevolved metal-poor stars analysed by spectral synthesis of the near-UV NH band at 3360...

Rings are common in galaxies. Several kinds of rings are known: collisional, polar, and resonance rings, of which the latter is by far most common. Resonance...

Bellazzini et al. claim that López-Corredoira et al. warp model is totally unable to reproduce the Canis Major structure in the red clump stars. However, slight...

Over the past years observations of young and populous star clusters have shown that the stellar initial mass function (IMF) appears to be an invariant...
