(author), Cazaux, S.M. (author)Context. Mid-infrared observations of photodissociation regions (PDRs) are dominated by strong emission features called aromatic infrared bands (AIBs). The most prominent AIBs are found at 3.3, 6.2, 7.7, 8.6, and 11.2 µm. The most sensitive, highest-resolution infrared spectral imaging data ever taken of the prototypical PDR, the Orion Bar, have...journal article 2024

Kong, I. (author), Janssen, M.F.W.H.A. (author), Bharosa, Nitesh (author)The quantum computing-based threats call for a critical information infrastructure to modify widely used cryptographic algorithms to ones that are quantum-safe (QS). Yet, little scholarly research has been undertaken to study QS transition, and the guidance to prepare for socio-technical predicaments of the transition falls short. To address the...journal article 2023

Gong, Y. (author), Janssen, M.F.W.H.A. (author)Enterprise architecture (EA) initiatives consist of functions, processes, tools, instruments, and principles to guide the design of IT and its alignment with business. EA is often presented as a silver bullet to ensure that IT contributes to business. Yet, many EA initiatives do not work out or even fail, but in the literature this area is...journal article 2022

Sulfur is a biogenic element used as a tracer of the evolution of interstellar clouds to stellar systems. However, most of the expected sulfur in molecular clouds remains undetected. Sulfur disappears from the gas phase in two steps. The first depletion occurs during the translucent phase, reducing the gas-phase sulfur by 7-40 times,...journal article 2022

(author)Dusty star-forming galaxies (DSFGs) at redshift z ≥ 1 are among the most vigorously star-forming galaxies in the Universe. However, their dense (≥10 <sup>5</sup>cm <sup>-3</sup>) gas phase - typically traced by HCN(1-0) - remains almost entirely unexplored: only two DSFGs have been detected in HCN(1-0) to date. We present the results of a...journal article 2022
