Merger origin for counterrotating cores in elliptical galaxies.
Using numerical simulations of the merger between a high- and a low-luminosity elliptical galaxy the authors show that this type of merger can result in an...
Observan una gran corriente de marea en la galaxia del Sombrero
Según el modelo cosmológico más actualizado, las grandes galaxias espirales como la Vía Láctea crecieron absorbiendo galaxias menores en una especie de...
Searching for Tidal Remnants in the Milky Way: Photometric Survey of Globular Clusters
The picture of building the Milky Way halo from the merger of protogalactic fragments is considered the local manifestation of the hierarchical galaxy formation...
Secondary Infall in the Seyfert’s Sextet: A Plausible Way Out of the Short Crossing Time Paradox
We used integral field spectroscopy from CALIFA DR3 and multiwavelength publicly available data to investigate the star formation histories of galaxies in the...
Testing Mass Determinations of Supermassive Black Holes via Stellar Kinematics
We investigate the accuracy of mass determinations MBH of supermassive black holes in galaxies using dynamical models of the stellar kinematics. We compare 10...
