Fourteen candidate RR Lyrae star streams in the inner Galaxy
Cecilia Mateu, Justin I. Read, Daisuke Kawata
We apply the GC3 stream-finding method to RR Lyrae stars (RRLS) in the Catalina survey. We find two RRLS stream candidates at confidence and another 12 at confidence…
The influence of Massive Black Hole Binaries on the Morphology of Merger Remnants
Elisa Bortolas, Alessia Gualandris, Massimo Dotti +1
Massive black hole (MBH) binaries, formed as a result of galaxy mergers, are expected to harden by dynamical friction and three-body stellar scatterings, until emission of gravitat…
The Local Dark Matter Density from SDSS-SEGUE G-dwarfs
Sofia Sivertsson, Hamish Silverwood, Justin I. Read +2
We derive the local dark matter density by applying the integrated Jeans equation method from Silverwood et al. (2016) to SDSS-SEGUE G-dwarf data processed and presented by Büdenbe…
The Magellanic Inter-Cloud Project (MAGIC) III: First spectroscopic evidence of a dwarf stripping a dwarf
Ricardo Carrera, Blair C. Conn, Noelia E. D. Noël +2
The Magellanic Bridge (MB) is a gaseous stream that links the Large (LMC) and Small (SMC) Magellanic Clouds. Current simulations suggest that the MB forms from a recent interaction…
Probing dark matter with star clusters: a dark matter core in the ultra-faint dwarf Eridanus II
Filippo Contenta, Eduardo Balbinot, James A. Petts +6
We present a new technique to probe the central dark matter (DM) density profile of galaxies that harnesses both the survival and observed properties of star clusters. As a first a…
