Revisiting mass estimates of the Milky Way
Yongjun Jiao, Francois Hammer, Haifeng Wang +2
We use the rotation curve from Gaia data release (DR) 3 to estimate the mass of the Milky Way. We consider an Einasto density profile to model the dark matter component. We extrapo…
The Formation of Magellanic System and the total mass of Large Magellanic Cloud
Jianling Wang, Francois Hammer, Yanbin Yang +1
The Magellanic Stream is unique to sample the MW potential from ~50 kpc to 300 kpc, and is also unique in constraining the LMC mass, an increasingly important question for the Loca…
The Andromeda Galaxy's Last Major Merger: Constraints from the survey of Planetary Nebulae
Souradeep Bhattacharya, Magda Arnaboldi, Ortwin Gerhard +7
The Andromeda galaxy (M 31) has experienced a tumultuous merger history as evidenced by the many substructures present in its inner halo. We use planetary nebulae (PNe) as chemodyn…
The survey of planetary nebulae in Andromeda (M31) VI. Kinematics of M31 inner-halo substructures and comparison with major-merger simulation predictions
Souradeep Bhattacharya, Magda Arnaboldi, Francois Hammer +4
M31 has experienced a recent tumultuous merger history as evidenced from the many substructures that are still present in its inner halo, particularly the G1-Clump, NE- and W- shel…
The accretion history of the Milky Way. I. How it shapes globular clusters and dwarf galaxies
Francois Hammer, Hefan Li, Gary A. Mamon +6
Halo inhabitants are individual stars, stellar streams, star and globular clusters, and dwarf galaxies. Here we compare the two last categories that include objects of similar stel…
Discovery of a new Local Group Dwarf Galaxy Candidate in UNIONS: Boötes V
Simon E. T. Smith, Jaclyn Jensen, Joel Roediger +12
We present the discovery of Boötes V, a new ultra-faint dwarf galaxy candidate. This satellite is detected as a resolved overdensity of stars during an ongoing search for new Local…
