We present integral field spectroscopic observations of the central region of the active galaxy NGC 4258 obtained with the fibre IFU system INTEGRAL. We have...
Blue Luminous Stars in Nearby Galaxies: Quantitative Spectral Analysis of M33 B-Type Supergiant Stars
We present the detailed spectral analysis of a sample of M33 B-type supergiant stars, aimed at the determination of their fundamental parameters and chemical...
Blue Luminous Stars in Nearby Galaxies—UIT 005: A Possible Link to the Luminous Blue Variable Stage
A detailed study of the blue supergiant UIT 005 (B2-2.5Ia+) in M 33 is presented. The results of our quantitative spectral analysis indicate that the star is a...
Blue straggler star (BSS) candidates have been observed in all old dwarf spheroidal galaxies (dSphs), however whether or not they are authentic BSSs or young...
Blue straggler stars in dwarf spheroidal galaxies - II. Sculptor and Fornax
The existence of blue straggler stars (BSSs) in dwarf spheroidal galaxies (dSphs) is still an open question. In fact, many BSS candidates have been observed in...

Bottom-heavy initial mass function in a nearby compact L★ galaxy
We present orbit-based dynamical models and stellar population analysis of Sloan Digital Sky Survey J151741.75-004217.6, a low-redshift (z = 0.116) early-type...
Box- and peanut-shaped bulges. III. A new class of bulges: Thick Boxy Bulges
Inspecting all 1224 edge-on disk galaxies larger than 2arcmin in the RC3 on Digitized Sky Survey (DSS) images (Lütticke et al. cite{lue2000a}) we have found...
