Detection of a large-scale stellar bar in the Milky Waydoi:10.1086/170853Martin Weinberg
Whereas unbarred disks present spiral arms nearly corotating with disk particles, strong barred models (bulged or bulge-less) quickly develop a bar-spiral structure dominant in density, with a pattern speed almost constant in radius (Roca-Fàbrega et al. 2013). Preliminary results also indicate ...
The Large Magellanic Cloud is the most massive satellite galaxy of the Milky Way, with an estimated mass exceeding a tenth of the mass of the Milky Way1–5. Just past its closest approach of about 50 kpc, and flying past the Milky Way at an astonishing s
However, information on the dust lanes of the Milky Way bar is harder to obtain due to our position within the Galactic disc.Aims.By comparing the distribution of dust and gas in the central regions of the Galaxy, we aim to obtain new insights into the properties of the offset dust lanes...
We present new gas flow models for the Milky Way inside the solar circle. Using a mass model derived from the COBE/DIRBE maps and clump giant star counts, and using a parametric model for the spiral arm pattern in the disk, we calculate the gas flow and compare with 12CO observations. ...
Due to the absence of the atmosphere, the telescope delivers diffraction-limited, extremely sharp images, which have revealed unprecedented details of stars, star clusters, nebulae and other objects in the Milky Way and in other galaxies. Among the most spectacular results, HST has provided the ...
We present a dynamical model for gas transport, star formation and winds in the nuclear regions of galaxies, focusing on the Milky Way's Central Molecular ... Mark,R.,Krumholz,... - 《Monthly Notices of the Royal Astronomical Society》 被引量: 21发表: 2016年 Star Formation Properties in ...
1923: Mars releases Milky Way candy bars The Mars company debutedMilky Way candy barsin 1923. Despite the galactic name, the brand was actually inspired by malted milkshakes, which were extremely popular at the time, according to Mental Floss. ...
Methods: We compared the results of test particle simulations of the Milky Way with a potential that includes a rotating bar with observations from the RAVE survey. To this end we applied the RAVE selection function to the simulations and convolved these with the characteristic RAVE errors. We ...
Such bars are common in galaxies — even the Milky Way has a small bar — and they are thought to form when a spiral disk is perturbed and stars are sent from having more circular orbits to more elliptical paths. The diameter of the LMC is 9.96 kiloparsecs, or 32,469.6 light-years...
