Context. Milky Way analogs (MWAs) are defined on the basis of structural, kinematic, and global physical parameters. Our advanced approach to searching for MWAs...

We present spectroscopic observations of supernova 1994D in NGC 4526, an S0_3_ galaxy in the Virgo cluster 15Mpc distant. The datasets consist of the...

We report the case of the early-type disk galaxy NGC 4672 as a new example of a galaxy characterized by the orthogonal geometrical decoupling between bulge and...

NGC 5506 is a peculiar Seyfert (Sy) galaxy: it has a Sy2-like optical spectrum, but broad permitted infrared lines and a high X-ray luminosity as compared with...

The existence of massive galaxies lacking a classical bulge has often been proposed as a challenge to ΛCDM. However, recent simulations propose that a fraction...

We have acquired low- and intermediate-resolution spectroscopy at 11 positions across the nucleus of NGC 6210. As a consequence, we are able to map the...

Aims: NGC 6240 is a well-studied nearby galaxy system in the process of merging. Based on optical, X-ray, and radio observations, it is thought to harbor two...

Massive young clusters with rich populations of high-mass stars are ideal laboratories to explore their evolutionary paths. Despite being the most prominent...

Context. The stellar [α/Fe] abundance is sometimes used as a proxy for stellar age, following standard chemical evolution models for the Galaxy, as seen by...
