Stellar tidal streams around nearby spiral galaxies with deep imaging from amateur telescopes
David Martinez-Delgado, Michael Stein, Joanna D. Sakowska +26
Tidal interactions between massive galaxies and their satellites are fundamental processes in a Universe with L-Cold Dark Matter cosmology, redistributing material into faint featu…
Extragalactic Stellar Tidal Streams: Observations meet Simulation
Juan Miro-Carretero, Maria A. Gomez-Flechoso, David Martinez-Delgado +11
According to the well established hierarchical framework for galaxy evolution, galaxies grow through mergers with other galaxies and the LambdaCDM cosmological model predicts that…
Extragalactic Stellar Tidal Streams in the Dark Energy Survey
Juan Miro-Carretero, David Martinez-Delgado, Maria A. Gomez-Flechoso +7
Stellar tidal streams are a key tracer of galaxy evolution and have the potential to provide an indirect means for tracing dark matter. For the Local Group, many diffuse substructu…
Galactoseismology in cosmological simulations: Vertical perturbations by dark matter, satellite galaxies and gas
B. García-Conde, T. Antoja, S. Roca-Fàbrega +4
Only recently, complex models that include the global dynamics from dwarf satellite galaxies, dark matter halo structure, gas infalls, and stellar disk in a cosmological context be…
Planes of satellites around simulated disc galaxies: I.- Finding high-quality planar configurations from positional information and their comparison to MW/M31 data
Isabel Santos-Santos, Rosa Dominguez-Tenreiro, Hector Artal +6
We address the 'plane of satellites problem' by studying planar configurations around two disc galaxies with no late major mergers, formed in zoom-in hydro-simulations. Due to the…
Tracing out the northern stream of the Sagittarius dwarf galaxy with color- magnitude diagram techniques
D. Martinez-Delgado, M. A. Gomez-Flechoso, A. Aparicio
Standard cosmology predicts that dwarfs were the first galaxies to be formed in the Universe and that many of them merge afterwards to form bigger galaxies such as the Milky Way. T…
