Linking the brightest stellar streams with the accretion history of Milky Way-like galaxies
Alex Vera-Casanova, Facundo A. Gómez, Antonela Monachesi +8
According to the current galaxy formation paradigm, mergers and interactions play an important role in shaping present-day galaxies. The remnants of this merger activity can be use…
Systematic search for tidal features around nearby galaxies: I. Enhanced SDSS imaging of the Local Volume
Gustavo Morales, David Martínez-Delgado, Eva K. Grebel +3
In hierarchical models of galaxy formation, stellar tidal streams are expected around most, if not all, galaxies. Although these features may provide useful diagnostics of the C…
Satellite accretion in action: a tidally disrupting dwarf spheroidal around the nearby spiral galaxy NGC 253
Aaron J. Romanowsky, D. Martinez-Delgado, Nicolas F. Martin +7
We report the discovery of NGC 253-dw2, a dwarf spheroidal (dSph) galaxy candidate undergoing tidal disruption around a nearby spiral galaxy, NGC 253 in the Sculptor group: the fir…
Discovery of a stellar tidal stream around the Whale galaxy, NGC 4631
David Martinez-Delgado, Elena D'Onghia, Taylor S. Chonis +5
We report the discovery of a giant stellar tidal stream in the halo of NGC 4631, a nearby edge-on spiral galaxy interacting with the spiral NGC 4656, in deep images taken with a 40…
A Measurement of the Millimeter Emission and the Sunyaev-Zel'dovich Effect Associated with Low-Frequency Radio Sources
Megan B. Gralla, Devin Crichton, Tobias A. Marriage +38
We present a statistical analysis of the millimeter-wavelength properties of 1.4 GHz-selected sources and a detection of the Sunyaev-Zel'dovich (SZ) effect associated with the halo…
The Atacama Cosmology Telescope: Dusty Star-Forming Galaxies and Active Galactic Nuclei in the Southern Survey
Danica Marsden, Megan Gralla, Tobias A. Marriage +28
We present a catalog of 191 extragalactic sources detected by the Atacama Cosmology Telescope (ACT) at 148 GHz and/or 218 GHz in the 2008 Southern survey. Flux densities span 14-17…
