Mass Models of the Milky Way and Estimation of Its Mass from the Gaia DR3 Data Set
The Astrophysical Journal, 2023 We use data from the Gaia DR3 data set to estimate the mass of the Milky Way (MW) by analyzing the rotation curve in the range of distances 5 to 28 kpc. We consider three mass models: The first model adds a spherical dark matter (DM) halo, following the ...

The connection between the host halo and the satellite galaxies of the Milky Way [PDF]
, 2016 Many properties of the Milky Way's dark matter halo, including its mass assembly history, concentration, and subhalo population, remain poorly constrained.

The Three-phase Evolution of the Milky Way
The Astrophysical JournalWe illustrate the formation and evolution of the Milky Way over cosmic time, utilizing a sample of 10 million red giant stars with full chemodynamical information, including metallicities and α -abundances from low-resolution Gaia XP spectra.

Mapping the Milky Way Disk with Gaia DR3: 3D Extended Kinematic Maps and Rotation Curve to ≈30 kpc
The Astrophysical Journal, 2022 We apply a statistical deconvolution of the parallax errors based on Lucy’s inversion method (LIM) to the Gaia DR3 sources to measure their 3D velocity components in the range of Galactocentric distances R between 8 and 30 kpc with their corresponding ...

, 2012 We investigate the physical properties of the progenitors of today living Milky Way-like galaxies that are visible as Damped Lya Absorption systems and Lya Emitters at higher redshifts (z ~ 2.3,5.7).

Generalized Rotation Curves of the Milky Way from the GAIA DR3 Data Set: Constraints on Mass Models
The Astrophysical JournalThe circular velocity curve traced by stars provides a direct means of investigating the potential and mass distribution of the Milky Way. Recent measurements of the Galaxy’s rotation curve have revealed a significant decrease in velocity for Galactic ...

The Astrophysical Journal, 2023 We present a Galactic disk vertical velocity analysis using OB type stars (OB stars), red clump (RC) stars, and main-sequence turnoff (MSTO) stars with different average age populations crossmatched with LAMOST DR5 and Gaia DR3. We show that the vertical

Are the Milky Way and Andromeda unusual? A comparison with Milky Way and Andromeda analogues [PDF]
Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACT Our Milky Way provides a unique test case for galaxy evolution models because of our privileged position within the Milky Way’s disc. This position also complicates comparisons between the Milky Way and external galaxies, due to our inability to observe the Milky Way from an external point of view.

Improved COMPTEL maps of the milky way [PDF]
, 2000 In the course of the mission we have gradually developed an analysis method that separates in an iterative manner the celestial emission and the (a priori unknown) instrumental background. It has become our standard analysis tool for point sources.
