Real-time Broadband RFI Excision for the Upgraded GMRT
A real-time broadband RFI mitigation system has been developed for the Upgraded GMRT (uGMRT). Here, we report the engineering, imaging, and beam/pulsar results from the test observations in all the bands of the uGMRT during the monsoon of 2018 and 2019. Broadband power-line RFI is almost always present in uGMRT bands 2 (120 - 240 MHz), 3 (300 - 500 MHz) and 4 (550 - 850 MHz), but the monsoon period is chosen to understand the performance in the worst RFI situations arising due to an increase in…

Ultra-broadband spectral and polarisation entanglement using dispersion-engineered nanophotonic waveguides
In this paper, we propose exploiting dispersion-engineered nanophotonic waveguides in generating unprecedented ultra-broadband spectral and polarisation entanglement using spontaneous four-wave mixing parametric processes. We developed a simplified theoretical quantum framework to investigate and analyse these interactions under pulse source excitations. Using aluminum gallium arsenide and thin-film lithium niobate waveguides, we anticipate to obtain photon pairs with high-dimensional frequency…

Het veelbesproken compromis voor Cloud in de Rijksoverheid werkt niet.
"Het klinkt zo aantrekkelijk om te zeggen dat onze bestanden hier staan (veilig 🇳🇱/🇪🇺) en onze email en tekstverwerking daar (onveilig 🇺🇸). Maar deze werelden zijn niet te scheiden."

Mail in de VS en je bestanden hier? Het werkt niet - Bert Hubert's writings
Zoals ik gisteren schreef, onze maatschappij en overheden draaien in steeds grotere mate op Amerikaanse clouds, en we maken ons hier nu terecht zorgen over. Want het is toch niet leuk dat de Amerikanen mee kunnen lezen in onze (overheids)gegevens, of zonder pardon de steker eruit kunnen trekken. We zouden dit graag snel op willen lossen, maar er zijn geen makkelijke en goedkope keuzes. Inmiddels heeft (volgens geruchten) bijna de hele centrale rijksoverheid besloten om de email toch nog op eige…

Controlling Effective Hamiltonians: Broadband Pulsed Dynamic Nuclear Polarization by Constrained Random Walk and Non-linear Optimization
We present constrained random walk (cRW) and figure of merit (FOM) based non-linear optimization procedures for systematic design and fundamental understanding of magnetic resonance experiments dressing bilinear and linear effective Hamiltonians to provide broadband polarization transfer. cRW can be used directly for fast random experiment design, or in combination with non-linear optimization or optimal control, leveraging the optimization of a FOM function for efficient control of linear and …

A Dichotomy of the Mass-Metallicity Relation of Exoplanetary Atmospheres Demarcated by their Birthplace
Atmospheric observations by JWST raise a growing evidence that atmospheric metallicity exhibits an anti-correlation with masses of giant exoplanets. While such a trend was anticipated by planetesimal-based planet formation models, it remains unclear what kind of atmospheric metallicity trends emerge from pebble-based planet formation. Moreover, while recent studies of solar system Jupiter suggest that uppermost observable atmosphere may not represent the bulk envelope composition, it remains un…

Broadband Low-Resolution Spectrograph -- SpectrumMate LR
This paper presents the development and application of SpectrumMate LR, a broadband, low-resolution spectrograph for small telescope use. SpectrumMate LR is designed to offer affordable, accessible spectroscopic capabilities for amateur astronomers and educators, inspired by the need for versatile instruments in amateur and educational settings. Utilising a 300 grooves/mm grating, 80 mm collimator and objective lenses, SpectrumMate LR is optimised to perform analyses across the visible spectrum…
