The S2 Stream: the shreds of a primitive dwarf galaxy
David S. Aguado, G. C. Myeong, Vasily Belokurov +12
The S2 stream is a kinematically cold stream that is plunging downwards through the Galactic disc. It may be part of a hotter and more diffuse structure called the Helmi stream. We…
A MegaCam Survey of Outer Halo Satellites. VII. A Single Sérsic Index v/s Effective Radius Relation for Milky Way Outer Halo Satellites
Sebastián Marchi-Lasch, Ricardo R. Muñoz, Felipe A. Santana +6
In this work we use structural properties of Milky Way's outer halo () satellites (dwarf spheroidal galaxies, ultra-faint dwarf galaxies and globular cluste…
Wide binaries in ultra-faint galaxies: a window onto dark matter on the smallest scales
Jorge Peñarrubia, Aaron D. Ludlow, Julio Chanamé +1
We carry out controlled -body simulations that follow the dynamical evolution of binary stars in the dark matter (DM) haloes of ultra-faint dwarf spheroidals (dSphs). We find th…
A starburst in the core of a galaxy cluster: The dwarf irregular NGC 1427A in Fornax
Marcelo D. Mora, Julio Chanamé, Thomas H. Puzia
Gas-rich galaxies in dense environments such as galaxy clusters and massive groups are affected by a number of possible types of interactions with the cluster environment, which ma…
Schwarzschild Models for the Galaxy
Julio Chanamé
Schwarzschild's orbit-superposition technique is the most developed and well-tested method available for constraining the detailed mass distributions of equilibrium stellar systems…
HST's hunt for intermediate-mass black holes in star clusters
Julio Chanamé, Justice Bruursema, Rupali Chandar +3
Establishing or ruling out, either through solid mass measurements or upper limits, the presence of intermediate-mass black holes (IMBHs) at the centers of star clusters would prof…
