TRILEGAL, a TRIdimensional modeL of thE GALaxy: Status and FutureRed Giants as Probes of the Structure and Evolution of the Milky Way

open access: yes, 2012
We briefly describe TRILEGAL, a TRIdimensional modeL of thE GALaxy, and its more recent developments. Particularly relevant is the recent inclusion of a kinematical module to the code, and the present efforts to provide a more solid calibration of Milky ...

Icarus Revisited: An Ancient, Metal-poor Accreted Stellar Stream in the Disk of the Milky Way

open access: yesThe Astrophysical Journal
The search for accreted satellites in the Galactic disk is a challenging task, to which Gaia plays a crucial role in synergy with ground-based spectroscopic surveys. In 2021, P. Re Fiorentin et al.

A 3D Chemodynamical Census of Inner-Galaxy Metal-poor Giants to [Fe/H] ∼ −3.5

open access: yesThe Astrophysical Journal Letters
The earliest assembly of the Milky Way remains poorly understood, yet the spatial, chemical, and kinematic properties of its most metal-poor stars provide a unique fossil record of its proto-Galaxy phase.

Terraforming the Milky Way galaxy

open access: yes, 2023
After terraforming the entire Milky Way galaxy, create habitats in two phases: 1.Create a habitat in the entire Solar System only for humans to live in. 2.Create a habitat in the remaining (terraformed) galaxy for all the non-human creatures resurrected on Earth and transport them using mega spaceships.

Simulating supernova feedback in galaxy disks [PDF]

open access: yes, 2012
In this thesis I examine supernova feedback in hydrodynamical simulations of galaxy disks. Understanding this process entails the numerical evaluation of cooling in radiative shocks, and we present a set of simulations using two widely used numerical ...

What Is Missing from the Local Stellar Halo?

open access: yesThe Astrophysical Journal
The Milky Way’s stellar halo, which extends to >100 kpc, encodes the evolutionary history of our Galaxy. However, most studies of the halo to date have been limited to within a few kiloparsecs of the Sun.

The disk rotation of the Milky Way Galaxy [PDF]

open access: yes, 1999
The rotation of the disk of the Milky Way Galaxy is analyzed. It rotates neither as a solid disk, nor in accordance with individual keplerian orbits. Rather the disk executes a form of differential rotation which suggests that a considerable fraction of ...

The Stellar Disk Structure Revealed by the Mono-age Populations of the LAMOST Red Clump Star Sample

open access: yesThe Astronomical Journal
Understanding the structure of the Galactic disk is crucial for understanding the formation and evolutionary history of the Milky Way. This study examines the structure of the Galactic disk by analyzing a sample of 138,667 primary red clump (RC) stars ...

Metallicity Mapping of the Ionized Diffuse Gas at the Milky Way Disk–Halo Interface

open access: yesThe Astrophysical Journal
Metals in the diffuse, ionized gas at the boundary between the Milky Way’s interstellar medium (ISM) and circumgalactic medium, known as the disk–halo interface (DHI), are valuable tracers of the feedback processes that drive the Galactic fountain ...

Rotation and mass in the Milky Way and spiral galaxies [PDF]

open access: yesPublications of the Astronomical Society of Japan, 2016
Abstract Rotation curves are the basic tool for deriving the distribution of mass in spiral galaxies. In this review, we describe various methods to measure rotation curves in the Milky Way and spiral galaxies. We then describe two major methods to calculate the mass distribution using the rotation curve.
