Along with Kauflmann, Kuhnau had also been discussed, probably first as organist. Elias Lindner, the organist at the cathedral in Freiburg, was mentioned. Apply properties of real numbers to simplify algebraic expressions, including polynomials. Use matrices to solve mathematical situations and contextual problems. Understand, represent, and analyze patterns, In particular, this algorithm was designed for the portion of LEGUE targeting the Galactic halo, in which we attempt to balance a variety of science goals that require stars at fainter magnitudes than can be completely sampled by LAMOST.
We present statistics on observing hours from to , and the sky brightness, seeing, and sky transparency from to at the site. We investigate effects of the site conditions on the survey plan. Operable hours each month show a strong correlation with season: The seeing and the sky transparency also vary with season.
Although the seeing is worse in windy winters, and the atmospheric extinction is worse in the spring and summer, the site is adequate for the proposed scientific program of the LAMOST survey. Fan Yang, Jeffrey L. We discuss the regions of sky in which spectroscopic candidates were selected, and the motivations for selecting each of these sky areas. The target selection categories and scientific goals motivating them are briefly discussed, followed by a detailed overview of how these selection functions were implemented.

Humanoid galactic history
This scheme overemphasizes rare objects and de-emphasizes more populated regions of magnitude and color phase space, while ensuring a smooth, well-understood selection function. A demonstration of plate design is presented based on the Shack-Hartmann star catalog and an input catalog that was generated by our target selection routines.
Adjacent plates may have some small overlapping area. Each plate covers an area of 2.
For each plate, we create an input catalog in the magnitude range The stars are selected to satisfy the requirements of the fiber positioning system and have a uniform distribution in the I vs. B — I color-magnitude diagram.

Our final input catalog consists of 12 objects on each of eight plates that are observable during the winter observing season from the Xinglong Station of the National Astronomical Observatory of China. We raise the possibility that the very dense, compact companion of PSR J, which has a Jupiter-like mass, is an exotic quark object rather than a light helium or carbon white dwarf.
The exotic hypothesis naturally explains some of the observed features, and provides quite strong predictions for this system, to be confirmed or refuted in feasible future studies. We propose a two-component jet model consistent with the observations of several gamma ray bursts GRBs and active galactic nuclei AGNs.
The jet consists of inner and outer components, which are supposed to be driven by the Blandford-Znajek BZ and Blandford-Payne BP processes, respectively. The baryons in the BP jet are accelerated centrifugally via the magnetic field anchored in the accretion disk. The BZ jet is assumed to be entrained in a fraction of accreting matter leaving the inner edge of the accretion disk, and the baryons are accelerated in the conversion from electromagnetic energy to kinetic energy.
We mainly focused on the fitting method and the metallicity gradient for the M31 GC sample. Here, we analyze and further discuss the dynamics, metallicity and age, and their distributions, as well as the relationships between these parameters.
Earth's Galactic History
In our work, eight more confirmed GCs in the halo of M31 were observed, most of which lack previous spectroscopic information. Firstly, we measured the Lick absorption-line indices and the radial velocities. Additionally, we plot metallicity distributions with the largest sample of M31 GCs so far and show the bimodality is not significant, and the number of metal-poor and metal-rich groups becomes comparable. The spatial distributions show that the metal-rich group is more centrally concentrated but the metal-poor group occupies a more extended halo.
In addition, the young population is centrally concentrated but the old population is more spatially extended towards the outer halo. Bipolar outflow is confirmed in the molecular cloud, and the excited star of the HII region could be the driving source of the outflow.
