Novel constraints on the particle nature of dark matter from stellar streams

Nilanjan Banik, Jo Bovy, Gianfranco Bertone +2

Tidal streams are highly sensitive to perturbations from passing dark matter (DM) subhalos and thus provide a means of measuring their abundance. In a recent paper, we analyzed the…

Where do quasar hosts lie with respect to the size-mass relation of galaxies?

John D. Silverman, Tommaso Treu, Xuheng Ding +8

The evolution of the galaxy size - stellar mass (Mstellar) relation has been a puzzle for over a decade. High redshift galaxies are significantly more compact than galaxies observe…
