Once in a blue stream: Detection of recent star formation in the NGC 7241 stellar stream with MEGARA
David Martinez-Delgado, Santi Roca-Fabrega, Armando Gil de Paz +23
In this work we study the striking case of a narrow blue stream around the NGC 7241 galaxy and its foreground dwarf companion. We want to figure out if the stream was generated by…
Phase spirals in cosmological simulations of Milky Way-size galaxies
Begoña García-Conde, Santi Roca-Fàbrega, Teresa Antoja +2
We study the vertical perturbations in the galactic disc of the Milky Way-size high-resolution hydrodynamical cosmological simulation named GARROTXA. We detect phase spirals in the…
The AGORA High-resolution Galaxy Simulations Comparison Project. III: Cosmological zoom-in simulation of a Milky Way-mass halo
Santi Roca-Fàbrega, Ji-hoon Kim, Loic Hausammann +20
We present a suite of high-resolution cosmological zoom-in simulations to of a halo at , obtained using seven contemporary astrophysical simul…
A feather on the hat: Tracing the giant stellar stream around the Sombrero galaxy
David Martinez-Delgado, Javier Roman, Denis Erkal +7
Recent evidence of extremely metal-rich stars found in the Sombrero galaxy (M104) halo suggests that this galaxy has undergone a recent major merger with a relatively massive galax…
Hidden depths in the local Universe: The Stellar Stream Legacy Survey
David Martinez-Delgado, Andrew P. Cooper, Javier Roman +26
Mergers and tidal interactions between massive galaxies and their dwarf satellites are a fundamental prediction of the Lambda-Cold Dark Matter cosmology. These events are thought t…
