THE SKELETON OF THE MILKY WAY [PDF]
The Astrophysical Journal, 2015 Recently, Goodman et al. (2014) argued that the very long, very thin infrared dark cloud "Nessie" lies directly in the Galactic mid-plane and runs along the Scutum-Centaurus arm in position-position-velocity ($p-p-v$) space as traced by lower density $\rm {CO}$ and higher density ${\rm NH}_3$ gas.

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 ...

The Baryons in the Milky Way Satellites [PDF]
Monthly Notices of the Royal Astronomical Society, Volume 419, Issue 4, pp. 3304-3318. (MNRAS Homepa, 2011 We investigate the formation and evolution of satellite galaxies using smoothed particle hydrodynamics (SPH) simulations of a Milky Way(MW)-like system, focussing on the best resolved examples, analogous to the classical MW satellites. Comparing with a pure dark matter simulation, we find that the condensation of baryons has had a relatively minor ...

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.

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.

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 ...

Neocatastrophism and the Milky Way Astrobiological Landscape [PDF]
Serbian Astronomical Journal, 2008 The number and distribution of habitable planets in the Milky Way is one of the foremost problems of contemporary astrobiological research. We investigate the effects of applying general neocatastrophic paradigm to the evolution of the Galactic Habitable
