The advent of the second data release of the Gaia mission, in combination with data from
large spectroscopic surveys, is revolutionizing our understanding of the Galaxy. Thanks to …

We investigate the non-adiabatic effect of time-dependent deformations in the Milky Way
(MW) halo potential on stellar streams. Specifically, we consider the MW's response to the …

Stream stars removed by tides from their progenitor satellite galaxy or globular cluster act as
a group of test particles on neighbouring orbits, probing the gravitational field of the Milky …

We analyse stellar streams in action-angle coordinates combined with recent local direct
acceleration measurements to provide joint constraints on the potential of our galaxy. Our …

We introduce the emPDF (Empirical Distribution Function), a novel dynamical modeling
method that infers the gravitational potential from kinematic tracers with optimal statistical …

Astronomy is unique among most other scientific fields due to the route which we must take
to unearth the principles that govern our objects of study. The timelines over which most …

The mass distribution of the Milky Way (MW) has been the subject of a considerable amount
of research, and yet many of its properties remain poorly constrained. We have developed …
