Dynamics of tidal dwarf galaxies in the system Arp 72

Osvan M. Portilla-Narvaez, Javier Zaragoza-Cardiel, Gisela N. Ortiz-León +6

Some interactions between galaxies produce tidal tails primarily composed of material from their disks. Within these tails, concentrations of gas and stars can form, resembling dwa…

Assessing the accuracy of the star formation rate measurements by direct star count in molecular clouds

Sami Dib, Jian Wen Zhou, Sébastien Comerón +8

Star formation estimates based on the counting of YSOs is commonly applied to nearby star-forming regions in the Galaxy. With this method, the SFRs are measured using the counts of…

The AMIGA sample of isolated galaxies. XIV. Disc breaks and interactions through ultra-deep optical imaging

P. M. Sánchez-Alarcón, J. Román, J. H. Knapen +10

In the standard cosmological model of galaxy evolution, mergers and interactions play a fundamental role in shaping galaxies. Galaxies that are currently isolated are thus interest…

The massive relic galaxy NGC 1277 is dark matter deficient. From dynamical models of integral-field stellar kinematics out to five effective radii

Sébastien Comerón, Ignacio Trujillo, Michele Cappellari +7

According to the CDM cosmology, present-day galaxies with stellar masses should contain a sizable fraction of dark matter within their stellar bo…

The complex multi-component outflow of the Seyfert galaxy NGC 7130

S. Comerón, J. H. Knapen, C. Ramos Almeida +1

AGN are a key ingredient for understanding galactic evolution. AGN-driven outflows are one of the manifestations of feedback. The AO mode for MUSE at the VLT permits to study the i…
