Mapping the Milky Way at 21 cm Wave Length with SALSA Radio Telescope

open access: yes, 2018
<p>Milky-Way-Mapping</p> <p>Mapping of the Milky Way is a galactic mapping at 21 cm Hydrogen spectrum to determine the Spiral Structure of Milky Way Galaxy in different Galactic planes from Galactic Longitude 6-225 Degree and Latitude ...

The Milky Way’s Circular Velocity Curve Measured Using Element Abundance Gradients

open access: yesThe Astrophysical Journal
Spectroscopic surveys now supply precise stellar label measurements such as element abundances for large samples of stars throughout the Milky Way. These element abundances are known to correlate with orbital actions or other dynamical invariants.

A comparison of the Andromeda and Milky Way galaxies [PDF]

open access: yesSymposium - International Astronomical Union, 1985
A comparison of some of the basic properties of M31 and the Milky Way indicates that in almost every respect M31 is larger than the Galaxy. It is more luminous, redder, more massive, and of earlier Hubble type. A detailed comparison of the spiral structure, based on optical tracers, for comparable areas in the outer parts of each galaxy shows ...

Patterns of wild meat and other protein consumption in the periphery of Salonga National Park, Democratic Republic of the Congo

open access: yesPeople and Nature, EarlyView.
Abstract In Central Africa, human activities are severely impacting terrestrial and aquatic wildlife, threatening the food security of millions of people. Accordingly, sustainable use of wildlife is crucial for the nutrition and livelihoods of many rural communities in the region.

A study of radio continuum emission of the Milky Way Galaxy [PDF]

open access: yes, 1996
The synchrotron emissivity distribution of the Milky Way Galaxy has been modelled from the 408 MHz allsky survey of Haslam et al.(1982) after separation of its thermal component with the help of IRAS 60 micron emission(Broadbent et al 1989).

The Age-dependent Vertical Actions of Young Stars in the Galaxy

open access: yesThe Astrophysical Journal
Stars in the Galactic disk are born on cold, nearly circular orbits with small vertical excursions. After their birth, their orbits evolve, driven by small- or large-scale perturbations in the Galactic disk’s gravitational potential.

Utopia Remembers: The Soviet Past in the Imagined Communist Future

open access: yesThe Russian Review, EarlyView.
Abstract After a twenty‐five‐year hiatus, the reappearance of utopian literature in 1957 prompted Soviet literary watchdogs to corral the subgenre into an ideologically‐acceptable mold. A key requirement was for future generations to be depicted as reverently commemorating the past.

The Stellar Halo of the Galaxy is Tilted and Doubly Broken

open access: yesThe Astronomical Journal, 2022
Modern Galactic surveys have revealed an ancient merger that dominates the stellar halo of our galaxy (Gaia–Sausage–Enceladus, GSE). Using chemical abundances and kinematics from the H3 Survey, we identify 5559 halo stars from this merger in the radial ...

On the spiral structure of the Milky Way Galaxy [PDF]

open access: yesAstronomy Reports, 2011
We consider the possible pattern of the overall spiral structure of the Galaxy, using data on the distribution of neutral (atomic), molecular, and ionized hydrogen, on the base of the hypothesis of the spiral structure being symmetric, i.e. the assumption that spiral arms are translated into each other for a rotation around the galactic center by 180° (

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

open access: yesExperimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...
