Direct assessment of the sensitivity drift of SQM sensors installed outdoors Bará S., Marco E., J. Ribas S., Garcia Gil M., Sánchez de Miguel A. and Zamorano J Long-term monitoring of the evolution of the artificial night sky brightness is a key tool for developing science-informed public policies and assessing the efficacy of light pollution … Read more
Suitability of blue filter ophthalmic lenses with respect to the use with mobile devices and computers J. Arines, O. Rodríguez Blue light comprises the electromagnetic spectrum between approximately 380-500 nm. The sun is the main source of blue light, although we also receive emissions of this type of light by electronic devices and artificial lighting. … Read more
The proliferation of space objects is a rapidly increasing source of artificial night sky brightness M Kocifaj, F Kundracik, J C Barentine, S Bará The population of artificial satellites and space debris orbiting the Earth imposes non-negligible constraints on both space operations and ground-based optical and radio astronomy. The ongoing deployment of several satellite ‘mega-constellations’ … Read more
What should be done to the measured Zernike coefficients when conjugating the pupil and wavefront sensor planes with a 4f system: discussion Justo Arines The aim of this paper is to describe and demonstrate what should be done to the measured Zernike coefficients when conjugating the pupil and wavefront sensor planes with a 4𝑓 system. … Read more
A multi-band map of the natural night sky brightness including Gaia and Hipparcos integrated starlight Masana, E., Carrasco, J.M, Bará, S., Ribas, S.J The natural night sky brightness is a relevant input for monitoring the light pollution evolution at observatory sites, by subtracting it from the overall sky brightness determined by direct measurements. It is … Read more
How did correlative atomic force microscopy and super-resolution microscopy evolve in the quest for unravelling enigmas in biology? Adelaide Miranda, Ana I. Gómez-Varela, Andreas Stylianou, Liisa M. Hirvonen, Humberto Sánchez and Pieter A. A. De Beule With the invention of the Atomic Force Microscope (AFM) in 1986 and the subsequent developments in liquid imaging and … Read more

Ultraintense Femtosecond Magnetic Nanoprobes Induced by Azimuthally Polarized Laser Beams Manuel Blanco, Ferran Cambronero, M. Teresa Flores-AriasM. Teresa Flores-Arias We report a novel scheme to generate laser-induced, ultrafast, intense (Tesla scale), spatially isolated, magnetic fields. Three-dimensional particle-in-cell simulations show that a femtosecond azimuthally polarized infrared vector beam, aimed at a conducting circular aperture, produces an … Read more
Choice of Jacobi–Fourier phase masks for wavefront coding under different f-number Enrique González-Amador, Alfonso Padilla-Vivanco, Justo Arines, Miguel Olvera-Angeles and Eva Acosta Wavefront coding (WFC) is an optical-digital technique that consists in introducing a suitable phase mask (PM) in the aperture plane able to extent, after image processing, the depth of field of an optical … Read more
