Does the Milky Way Have a Maximal Disk? [PDF]
, 1997 The Milky Way is often considered to be the best example of a spiral for which the dark matter not only dominates the outer kinematics, but also plays a major dynamical role in the inner galaxy: the Galactic disk is therefore said to be ``sub-maximal ...

Wolf-Rayet content of the Milky Way [PDF]
, 2015 An overview of the known Wolf-Rayet (WR) population of the Milky Way is presented, including a brief overview of historical catalogues and recent advances based on infrared photometric and spectroscopic observations resulting in the current census of 642

If so it is at variance with a popular belief in Hampshire, viz., that in whichever way the Milky Way may be seen over night, the wind is sure to blow ...

Short-lived Radionuclides in the Milky Way Galaxy [PDF]
EPJ Web of Conferences, 2023 The short-lived radionuclides (SLRs) have a half-life ≤ 100 Myr. The γ-ray observations and excess abundance of their daughter nuclides in various meteoritic phases confirm the existence of SLRs in the Galaxy and early solar system (ESS), respectively ...

Dense Gas in the Milky Way [PDF]
, 1996 We present a study of dense gas emission in the Milky Way in order to serve as a basis for comparison with extragalactic results. This study combines new observations of HCN, CS, and CO in individual GMCs and in the Milky Way plane with published studies

A Computer Vision Milky Way Compass
Applied Sciences, 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 ...

Low-frequency Radio Recombination Lines Away from the Inner Galactic Plane
The Astronomical Journal, 2023 Diffuse radio recombination lines (RRLs) in the Galaxy are possible foregrounds for redshifted 21 cm experiments. We use EDGES drift scans centered at −26.°7 decl. to characterize diffuse RRLs across the southern sky.

The spiral potential of the Milky Way [PDF]
, 2018 Context. The location of young sources in the Galaxy suggests a four-armed spiral structure, whereas tangential points of spiral arms observed in the integrated light at infrared and radio wavelengths indicate that only two arms are massive.
