Paolo Gondolo, Joakim Edsjo, Lars Bergstrom +2
The question of the nature of the dark matter in the Universe remains one of the most outstanding unsolved problems in basic science. One of the best motivated particle physics can…
The black hole mass vs bulge mass relationship in spiral galaxies
A. Marconi, D. Axon, J. Atkinson +15
We describe an on-going HST program aimed at determining the relationship between the nuclear black hole mass and bulge mass in spiral galaxies. We have selected a volume limited s…
