A non-axisymmetric potential for the Milky Way disk
Y. R. Khalil, B. Famaey, G. Monari +9
We provide a purely dynamical global map of the non-axisymmetric structure of the Milky Way disk. For this, we exploit the information contained within the in-plane motions of disk…
Reassessing the proper motions of M31/M33 with Gaia DR3. Unraveling systematic uncertainties
Samuel Rusterucci, Nicolas F. Martin, Else Starkenburg +1
We provide an updated inference of the proper motion of M31 using the Gaia DR3 proper motions of bright stars from the disc of M31. By refining the motion of the quasar reference f…
C-19 and Hot, Wide, Star Streams
Raymond G. Carlberg, Rodrigo Ibata, Nicolas F. Martin +4
The C-19 star stream has the abundance characteristics of an unusually metal poor globular cluster but kinematically is uncharacteristically hot and wide for a cluster stream, havi…
Simulations of cluster ultra-diffuse galaxies in MOND
Srikanth T. Nagesh, Jonathan Freundlich, Benoit Famaey +4
Ultra-diffuse galaxies (UDGs) in the Coma cluster have velocity dispersion profiles that are in full agreement with the predictions of Modified Newtonian Dynamics (MOND) in isolati…
Scale-dependent local primordial non-Gaussianity as a solution to the tension
Clément Stahl, Benoit Famaey, Rodrigo Ibata +3
For the last decade, several probes have pointed to a cosmological tension between the amplitude of density fluctuations extrapolated from the cosmic microwave background within th…
From inflation to dark matter halo profiles: the impact of primordial non-Gaussianities on the central density cusp
Clément Stahl, Nicolas Mai, Benoit Famaey +2
It has recently been shown that local primordial non-Gaussianities (PNG) with significant amplitude (), at small (Mpc) scales, can help in forming simulated…
