Kavli Affiliate: Alexey Bondal | Summary:Given a relatively projective birational morphism $fcolon Xto Y$ of smooth algebraic spaces with dimension of fibers bounded by 1, we construct tilting relative (over $Y$) generators $T_X,f$ and $S_X,f$ in $mathcalD^b(X)$. We develop a piece of general theory of strict admissible lattice filtrations in triangulated categories and show that […]
Kavli Affiliate: P. G. Steeneken | Summary:We explore the dynamics of a graphene nanomechanical oscillator coupled to a reference oscillator. Circular graphene drums are forced into self-oscillation, at a frequency fosc, by means of photothermal feedback induced by illuminating the drum with a continuous-wave red laser beam. Synchronization to a reference signal, at a frequency […]
Kavli Affiliate: Homer Neal | Summary:We describe a system to measure the Quantum Efficiency in the wavelength range of 300 nm to 1100 nm of 40×40 mm n-channel CCD sensors for the construction of the 3.2 gigapixel LSST focal plane. The technique uses a series of instrument to create a very uniform flux of photons […]
Kavli Affiliate: Richard Hills | Summary:This paper presents the first detailed investigation of the characteristics of mm/submm phase fluctuation and phase correction methods obtained using ALMA with baseline lengths up to ~15 km. Most of the spatial structure functions (SSFs) show that the phase fluctuation increases as a function of baseline length, with a power-law […]
Kavli Affiliate: Yukari Ito | Summary:Given a scheme $Y$ equipped with a collection of globally generated vector bundles $E_1, dots, E_n$, we study the universal morphism from $Y$ to a fine moduli space $mathcalM(E)$ of cyclic modules over the endomorphism algebra of $E:=mathcalO_Yoplus E_1opluscdots oplus E_n$. This generalises the classical morphism to the linear series […]
