The Astrophysical Journal, 2023 We introduce a two-particle correlation function (2PCF) for the Milky Way, constructed to probe spatial correlations in the orthogonal directions of the stellar disk in the Galactic cylindrical coordinates of R , ϕ , and z . We use this new tool to probe

Panspermia in a Milky Way–like Galaxy
The Astrophysical Journal, 2021 Abstract We study the process of panspermia in Milky Way–like galaxies by modeling the probability of successful travel of organic compounds between stars harboring potentially habitable planets. To this end, we apply the modified habitability recipe of Gobat & Hong to a model galaxy from the McMaster Unbiased Galaxy Simulations ...

LISA Detection of Binary Black Holes in the Milky Way Galaxy [PDF]
, 2017 Using the black hole merger rate inferred from LIGO, we calculate the abundance of tightly bound binary black holes in the Milky Way galaxy. Binaries with a small semimajor axis (.

The Astrophysical Journal, 2023 We have for the first time identified the early stellar disk in the Milky Way by using a combination of elemental abundances and kinematics. Using data from APOGEE DR17 and Gaia we select stars in the Mg–Mn–Al–Fe plane with elemental abundances ...

Three-Dimensional Distribution of the ISM in the Milky Way Galaxy: II. The Molecular Gas Disk [PDF]
, 2006 We created a three-dimensional distribution map of molecular gas throughout the Milky Way galaxy using the latest 12 CO (J =1–0) survey data cube and the rotation curve based on the kinematic distance. The radial distribution of the molecular gas shows a

Chemodynamical Analysis of Metal-rich High-eccentricity Stars in the Milky Way's Disk
The Astrophysical Journal, 2023 We present a chemodynamical analysis of 11,562 metal-rich, high-eccentricity halo-like main-sequence stars, which have been referred to as the Splash or Splashed Disk, selected from the Sloan Digital Sky Survey and Large Sky Area Multi-Object Fiber ...

Modelling the Milky Way as a dry Galaxy [PDF]
Monthly Notices of the Royal Astronomical Society, 2018 We construct a model for the Milky Way Galaxy composed of a stellar disc and bulge embedded in a dark-matter halo. All components are modelled as $N$-body systems with up to 8 billion equal-mass particles and integrated up to an age of 10\,Gyr. We find that net angular-momentum of the dark-matter halo with a spin parameter of $ =0.06$ is required to ...

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.

Three-Dimensional Distribution of the ISM in the Milky Way Galaxy: I. The H I Disk [PDF]
, 2003 We derived the three-dimensional distribution of H I gas in the Milky Way Galaxy using the latest H I survey data cubes and rotation curves. The distance of the H I gas was determined by the kinematic distance using a rotation curve.

A low pre-infall mass for the Carina dwarf galaxy from disequilibrium modelling [PDF]
, 2015 Dark matter only simulations of galaxy formation predict many more subhalos around a Milky Way like galaxy than the number of observed satellites. Proposed solutions require the satellites to inhabit dark matter halos with masses between one to ten ...
