The angular momentum spiral of the Milky Way disc in Gaia
Rashid Yaaqib, Aneesh P. Naik, Jorge Peñarrubia +1
Data from the Gaia mission shows prominent phase-space spirals that are the signatures of disequilibrium in the Milky Way (MW) disc. In this work, we present a novel perspective on…
First spiral arm detection using dynamical mass measurements of the Milky Way disk
Axel Widmark, Aneesh P. Naik
We apply the vertical Jeans equation to the Milky Way disk, in order to study non-axisymmetric variations in the thin disk surface density. We divide the disk plane into area cells…
The missing radial velocities of Gaia: a catalogue of Bayesian estimates for DR3
Aneesh P. Naik, Axel Widmark
In an earlier work, we demonstrated the effectiveness of Bayesian neural networks in estimating the missing line-of-sight velocities of Gaia stars, and published an accompanying ca…
Mapping Milky Way disk perturbations in stellar number density and vertical velocity using Gaia DR3
Axel Widmark, Lawrence M. Widrow, Aneesh Naik
We have mapped the number density and mean vertical velocity of the Milky Way's stellar disk out to roughly two kiloparsecs from the Sun using Gaia Data Release 3 (DR3) and complem…
The missing radial velocities of Gaia: blind predictions for DR3
Aneesh Naik, Axel Widmark
While Gaia has observed the phase space coordinates of over a billion stars in the Galaxy, in the overwhelming majority of cases it has only obtained five of the six coordinates, t…
Dark sector domain walls could explain the observed planes of satellites
Aneesh P. Naik, Clare Burrage
The observed `planes of satellites' around the Milky Way and other nearby galaxies are notoriously difficult to explain under the CDM paradigm. Here, we propose an alternative s…
