A search for stellar tidal streams around Milky Way analogues from the SAGA sample
Juan Miro-Carretero, David Martinez-Delgado, Silvia Farras-Aloy +6
Context. Stellar tidal streams are the result of tidal interactions between a central galaxy and lower mass systems like satellite galaxies or globular clusters. For the Local Grou…
A giant umbrella-like stellar stream around the tidal ring galaxy NGC 922
David Martinez-Delgado, Santi Roca-Fabrega, Juan Miro-Carretero +6
Tidal ring galaxies are observed rarely in the local universe due to their intrinsically transient nature. The tidal ring structures are the result of strong interactions between g…
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…
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…
Discovery of an ultra-diffuse galaxy in the Pisces-Perseus supercluster
David Martinez-Delgado, Ronald Laesker, Margarita Sharina +16
We report the discovery of DGSAT I, an ultra-diffuse, quenched galaxy located 10.4 degrees in projection from the Andromeda galaxy (M31). This low-surface brightness galaxy (mu_V =…
A comprehensive model for the Monoceros tidal stream
J. Penarrubia, D. Martinez-Delgado, H. W. Rix +7
We have compiled an extensive dataset on potential parts of the Monoceros tidal stream and performed an exhaustive survey of dwarf galaxy semi-analytic orbits in order to constrain…
