Schematic Model Of The Milky Way With Spiral Arms From Taylor Cordes

Milky Way Galaxy Arm Names Download scientific diagram | schematic model of the milky way with spiral arms from taylor & cordes (1993), with locations of massive star forming regions for which we have preliminary. Download scientific diagram | schematic showing the loci of the spiral arms according to the model by taylor & cordes (1993) and updated by cordes (2004), with an additional bisymmetric pair of.

Schematic Model Of The Milky Way With Spiral Arms From Taylor Cordes Download scientific diagram | "plain view" model of the spiral structure of the milky way (georgelin & georgelin 1976; taylor & cordes 1993) with overlaid positions and peculiar motions of the. The model showing characteristic galactocentric and zscales. † spiral arms in accord with a 4 arm logarithmic spiral and a local spiral arm (lazio & cordes 1998a,b). † a galactic center component that accounts for the very intense scattering toward sgr a*. † individual clumps and voids that are required for particular lines of sight. Titt et al. 2014). for example, spiral models with 2 or 4 arms have been proposed to best represent galactic morphology (elmegreen 1985; liszt 1985; georgelin & georgelin 1976; taylor & cordes 1993; weaver 1970) though there is evi dence that the gaseous and stellar components trace out dif ferent arm numbers, with gas favouring a 4 armed structure. Spiral arm geometry, adopting the free electron density model of taylor & cordes (1993) as a template. perhaps the only significant differences between this model and the one presented here is a reduction factor on the sagittarius carina arm, the galactic warp and a flair in the spiral arm scale height.

Both the three arm model and the four arm model can connect most spiral tracers. the fitting factor z = 0.17 for the best fitted three arm model is slightly larger than that for the four arm model (z = 0.16). however, the connections of the known arm segments differ in the two models. Solid and dashed black curves mark the four arm spiral model of taylor & cordes and the perseus arm (levine, blitz & heiles 2006), respectively. red lines indicate the region analysed in fig. 8 . open in new tab download slide.
