Of the mechanisms proposed to bring gaseous fuel into the central starburst regions of a galaxy, non-axisymmetries in the gravitational potential set up by...

We investigated the star formation activity and black hole scaling relations in a sample of 1 451 active galactic nuclei (AGNs) hosted by dwarf galaxies (log(M...

We present the results of a numerical adaptive mesh refinement hydrodynamical and N-body simulation in a Λ cold dark matter cosmology. We focus on the analysis...

Aims: Star-forming dwarfs are studied to elucidate the physical underpinnings of their fundamental plane. Processes controlling dynamics are evaluated...

We present new and stronger evidence for a previously reported relationship between galactic spiral arm pitch angle P (a measure of the tightness of spiral...

Spectroscopic analyses of gravity-sensitive line strengths give growing evidence towards an excess of low-mass stars in massive early-type galaxies (ETGs). Such...

Multi-object spectroscopic observations of A2254 were carried out at the TNG telescope in May and October 2009 and in March 2010. Our photometric observations...

The Gaia Galactic survey mission is designed and optimized to obtain astrometry, photometry, and spectroscopy of nearly two billion stars in our Galaxy. Yet as...

A wealth of tiny galactic systems populates the surroundings of the Milky Way. However, some of these objects might have originated as former satellites of the...
