Galactic archaeology based on star counts is instrumental to reconstruct the past mass
assembly of Local Group galaxies. The development of new observing techniques and data …

Dwarf irregular (dIrrs) galaxies are among the most common type of galaxy in the Universe.
They typically have gas-rich, low surface-brightness, metal-poor, and relatively thick disks …

We present the HIPASS Bright Galaxy Catalog (BGC), which contains the 1000 HI brightest
galaxies in the southern sky as obtained from the HI Parkes All-Sky Survey (HIPASS). The …

Long tails and streams of stars are the most noticeable traces of galaxy collisions. However,
their tidal origin was recognized only less than 50 years ago and more than 10 years after …

We have initiated a search for extended ultraviolet disk (XUV-disk) galaxies in the local
universe. Here we compare GALEX UV and visible-NIR images of 189 nearby (D< 40 Mpc) …

ABSTRACT A growing number of low luminosity and low surface brightness astronomical
objects challenge traditional notions of both galaxies and star clusters. To address this …

We study the gas kinematics of a sample of six isolated gas-rich low surface brightness
galaxies, of the class called ultra-diffuse galaxies (UDGs). These galaxies have recently …

Aims. We have performed a comprehensive multiwavelength analysis of a sample of 20
starburst galaxies that show the presence of a substantial population of very young massive …

For the first time, we reveal large amounts of cold molecular gas in a ram-pressure-stripped
tail, out to a large" intracluster" distance from the galaxy. With the Actama Pathfinder …

Observations and simulations have demonstrated that star formation in galaxies must be
actively suppressed to prevent the formation of overly massive galaxies. Galactic outflows …
