Three-Dimensional Distribution of the ISM in the Milky Way Galaxy: III. The Total Neutral Gas Disk [PDF]

open access: yes, 2015
We present newly obtained three-dimensional gaseous maps of the Milky Way Galaxy; HI, H$_2$ and total-gas (HI plus H$_2$) maps, which were derived from the HI and $^{12}$CO($J=1$--0) survey data and rotation curves based on the kinematic distance. The HI

24.77 Pflops on a Gravitational Tree-Code to Simulate the Milky Way Galaxy with 18600 GPUs [PDF]

open access: yesInternational Conference for High Performance Computing, Networking, Storage and Analysis, 2014
We have simulated, for the first time, the long term evolution of the Milky Way Galaxy using 51 billion particles on the Swiss Piz Daint supercomputer with our N-body gravitational tree-code Bonsai.

The Metal-weak Milky Way Stellar Disk Hidden in the Gaia–Sausage–Enceladus Debris: The APOGEE DR17 View

open access: yesThe 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 ...

Panspermia in a Milky Way–like Galaxy

open access: yesThe 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 ...

The evolution of isotope ratios in the Milky Way Galaxy [PDF]

open access: yes, 2011
Isotope ratios have opened a new window into the study of the details of stellar evolution, supernovae, and galactic chemical evolution. We present the evolution of the isotope ratios of elemental abundances (from C to Zn) in the solar neighbourhood ...

A Far-ultraviolet Fluorescent Molecular Hydrogen Emission Map of the Milky Way Galaxy [PDF]

open access: yes, 2017
We present the far-ultraviolet (FUV) fluorescent molecular hydrogen (H2) emission map of the Milky Way Galaxy obtained with FIMS/SPEAR covering ∼76% of the sky.

Two-point Correlation Function Studies for the Milky Way: Discovery of Spatial Clustering from Disk Excitations and Substructure

open access: yesThe 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

LISA Detection of Binary Black Holes in the Milky Way Galaxy [PDF]

open access: yes, 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 (.

Three-Dimensional Distribution of the ISM in the Milky Way Galaxy: II. The Molecular Gas Disk [PDF]

open access: yes, 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

open access: yesThe 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 ...
