The Milky Way and other spiral galaxies

EPJ Web of Conferences, 2012
Cosmologists have often considered the Milky Way as a typical spiral galaxy, and its properties have considerably influenced the current scheme of galaxy formation.

Molecular gas and star formation in the Milky Way

EPJ Web of Conferences, 2012
The dense molecular gas is the ideal tracer of the spiral structure in the Milky Way, and should be used intensively to solve the puzzle of its structure. In spite of our position inside the plane, we can hope to disentangle the structures, with position-

A Computer Vision Milky Way Compass

, 2023
The Milky Way is used by nocturnal flying and walking insects for maintaining heading while navigating. In this study, we have explored the feasibility of the method for machine vision systems on autonomous vehicles by measuring the visual features and ...

Formation of Galactic Components in Milky-Way-mass Galaxy Simulations [PDF]

, 2022
This thesis presents a computational study of the formation and evolution of Milky-Way-mass galaxies using FIRE-2 cosmological zoom-in simulations. All simulated galaxies experience an early period of bursty star formation that transitions to a late-time

Observational Constraints on Milky Way Halo Formation

, 2020
The formation of the Milky Way stellar halo is explored through the application of large-scale astronomical sky surveys. Multiple techniques are developed to identify and characterize metal-poor stars. Implications of the chemical abundance, spatial, and

The Milky Way - Our Home in the Universe

, 2018
Aakasha Ganga, Via Lactea or the Milky Way is our home in the Universe. The discovery of the telescope by Galileo Galilei had facilitated the sky watchers to notice a variety of geometrical forms in the sky.

GTC Follow-up Observations of Very Metal-poor Star Candidates from DESI

The Astrophysical Journal, 2023
The observations from the Dark Energy Spectroscopic Instrument (DESI) will significantly increase the numbers of known extremely metal-poor stars by a factor of ∼10, improving the sample statistics to study the early chemical evolution of the Milky Way ...
