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 ...

Wormhole in the Milky Way galaxy with global monopole charge
European Physical Journal C: Particles and Fields, 2022 Wormholes are tunnels or short-cuts in space-time, and their existence is very important for human civilization to express the vastness of space and time. So, it is necessary to analyze our own Milky Way galaxy if it can harbour any wormhole.

The size of the Milky Way galaxy
The size of a galaxy is one of the fundamental parameters that reflects its growth and assembly history. Traditionally, the size of the Milky Way has been characterized by the scale length of the disk, based on the assumption of an exponential density profile. Earlier scale length measurements suggest the Milky Way is an overly compact galaxy, compared

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 $λ=0.06$ is required to ...

The Astrophysical Journal, 2023 We continue our series of papers on phase-space distributions of stars in the Milky Way based on photometrically derived metallicities and Gaia astrometry, with a focus on the halo−disk interface in the local volume.

Stellar Bars in Isolated Gas-rich Spiral Galaxies Do Not Slow Down
The Astrophysical Journal, 2023 Elongated bar-like features are ubiquitous in galaxies, occurring at the centers of approximately two-thirds of spiral disks in the nearby Universe. Due to gravitational interactions between the bar and the other components of galaxies, it is expected ...

The Mass of the Milky Way Galaxy
, 2023 On the Basis of tabular values of the gravitational constant. The calculated mass of the nucleus of the milky way galaxy. The numerical value of the gravitational constant is determined by the mass of the nucleus of the milky way galaxy.
