Chemical dissection of merger-induced lopsidedness in Milky Way-like galaxies
Soumavo Ghosh, Paola Di Matteo, Chanda J. Jog +1
The Milky Way harbours a prominent m=1 lopsided distortion in both stellar and neutral gas distributions. On the other hand, chemo-dynamical studies have been proven to be effectiv…
Spiral Structure Diversity in Milky Way Analogs from TNG50: The Role of Gas and Disk Dynamics
Soumavo Ghosh, Elena D'Onghia
The generation of spiral arms and the mechanisms controlling their properties within a realistic cosmological framework - the complete understanding is still beyond our grasp. Usin…
Extraplanar emission in isolated edge-on late-type galaxies.II. The H kinematics
Minerva M. Sardaneta, Philippe Amram, Roberto Rampazzo +3
Isolated galaxies are rare yet invaluable for studying secular evolution, as their physical properties can remain largely unaffected by external influences for several billion year…
Quadrupole signature as a kinematic diagnostic to constrain bar properties : implications for the Milky Way
Soumavo Ghosh, Taavet Kalda, Paola Di Matteo +4
The presence of a 'butterfly' or a quadrupole structure in the stellar mean radial velocity () field of the Milky Way is well known from the Gaia and the APOGEE surveys. Pas…
