The mass of our Milky Way [PDF]
Science China: Physics, Mechanics and Astronomy, 2020 We perform an extensive review of the numerous studies and methods used to determine the total mass of the Milky Way. We group the various methods into seven broad classes, including: i) estimating Galactic escape velocity using high velocity objects; ii)

Symposium - International Astronomical Union, 2004 We present a new estimate of the mass of the Milky Way based on the escape velocity of a sample of distant stars, about 12 kpc from the Galactic centre and about 5 kpc from the plane of the Galaxy. Our sample is very different from previous escape-velocity studies, being compiled from an all-object spectroscopic survey of a region of sky.

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 ...

Nature, 1993 Direct photometric evidence has established that the central bulge of our Galaxy (the Milky Way) is actually a stellar bar. The dynamics of the bar will drive material into the Galaxy's centre but recent X-ray observations suggest that much of the inflowing gas is driven out again in a high-pressure galactic wind.

The Milky Way Nuclear Star Cluster [PDF]
, 2011 In the center of the Milky Way, as well as in many other galaxies, a compact star cluster around a very massive black hole is observed. One of the possible explanations for the formation of such Nuclear Star Clusters is based on the 'merging' of globular

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.

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.
