Dark Matter distribution in the Milky Way: microlensing and dynamical constraints
Dark Matter distribution Milky Way microlensing dynamical constraints
2011/10/20
We show that current microlensing and dynamical observations of the Galaxy allow to set interesting constraints on the Dark Matter local density and profile slope towards the galactic centre. Assuming...
(No) dynamical constraints on the mass of the black hole in two ULXs
accretion accretion discs – X-rays binaries – black hole physics – binaries spectroscopic
2010/11/12
We present the preliminary results of two Gemini campaigns to constrain the mass of the black hole in an ultraluminous X-ray source (ULX) via optical spectroscopy. Pilot studies of the optical counter...
