we study a system of weakly interacting electrons described by the energy dispersion $ \ xi ( \ mathbf { k } ) = k _ x ^ 2 - k _ y ^ 2 - \ mu $ in two dimensions within a renormalization group approach. this energy dispersion exhibits a neck - narrowing lifshitz transition at the critical chemical potential $ \ mu _ c ... | arxiv:1407.6732 |
various x - ray satellites have used the crab as a standard candle to perform their calibrations in the past. the calibration of xmm - newton, however, is independent of the crab nebula, because this object has not been used to adjust spectral calibration issues. in 2004 a number of special observations were performed ... | arxiv:astro-ph/0508235 |
we report on the discovery of a highly luminous, broad absorption line quasar at a redshift of $ z = 3. 87 $ which is positionally coincident, within one arcsecond, with the iras fsc source f08279 + 5255. a chance alignment of the quasar and the iras source is extremely unlikely and we argue that the optical and fir fl... | arxiv:astro-ph/9806171 |
