Resolving the optical emission lines of Lya blob 'B1' at z=2.38: another hidden quasar
R. A. Overzier, N. P. H. Nesvadba, M. Dijkstra +5
We have used the SINFONI near-infrared integral field unit on the VLT to resolve the optical emission line structure of one of the brightest (L~1e44 erg/s) and nearest (z=2.38) of…
Polydispersity stabilizes Biaxial Nematic Liquid Crystals
S. Belli, A. Patti, M. Dijkstra +1
Inspired by the observations of a remarkably stable biaxial nematic phase [E.v.d. Pol et al., Phys. Rev. Lett. 103, 258301 (2009)], we investigate the effect of size polydispersity…
Magnifying the early episodes of star formation: super star clusters at cosmological distances
E. Vanzella, M. Castellano, M. Meneghetti +27
We study the spectrophotometric properties of a highly magnified (μ~40-70) pair of stellar systems identified at z=3.2222 behind the Hubble Frontier Field galaxy cluster MACS~J041…
Energy-efficient time series processing in real-time with fluidic iontronic memristor circuits
T. M. Kamsma, Y. Gu, C. Spitoni +3
Iontronic neuromorphic computing has emerged as a rapidly expanding paradigm. The arrival of angstrom-confined iontronic devices enables ultra-low power consumption with dynamics a…
Low-Drift Flow Sensor with Zero-Offset Thermopile-Based Power Feedback
M. Dijkstra, T. S. J. Lammerink, Meint De Boer +3
A thermal flow sensor has been realised consisting of freely-suspended silicon-rich silicon-nitride microchannels with an integrated Al/poly-Si++ thermopile in combination with up-…
Screening of heterogeneous surfaces: charge renormalization of Janus particles
N. Boon, E. Carvajal Gallardo, S. Zheng +3
Nonlinear ionic screening theory for heterogeneously charged spheres is developed in terms of a mode-decomposition of the surface charge. A far-field analysis of the resulting elec…
