Cmbgg OmOl 2018/11/14 Slow-roll inflation is forbidden in the most clearly understood class of compactifications: in the large volume and small string coupling limit of all Calabi-Yau orientifold compactifications when only standard NS-NS three-form flux, R-R fluxes, D6-branes and O6-planes are included. With these ingredients, the first slow-roll parameter satisfies ϵ ≥ 27/13 whenever V > 0..

SOME SURVEYS TO LOOK FORWARD TO: 2018/11/14 SOME SURVEYS TO LOOK FORWARD TO: (Table from Natalie Roe)
LAMOST: The Large Sky Area Multi-Object Fibre Spectroscopic Telescope 2018/11/14 is a meridian reflecting Schmidt telescope. Using active optics technique to control its reflecting corrector makes it a unique astronomical instrument in combining large aperture with wide field of view. The available large focal plane may accommodate up to thousands of fibers, by which the collected light of distant and faint celestial objects down to 20.5 magnitude is fed into the spectrographs, promising a very high spectrum acquiring rate of ten-thousands of spectra per night. The telescope will be located at the Xinglong Station of National Astronomical Observatories. The project痴 budget is RMB 235 millions yuan. It will bring Chinese astronomy into the 21century with a leading role in wide field spectroscopy and in the fields of large scale and large sample astronomy and astrophysics.
