Advanced Functional Materials, EarlyView.A lack of standard approaches for testing and reporting the performance of metal halide perovskites and organic semiconductor radiation detectors has resulted in inconsistent interpretation of performance parameters, impeding progress in the field. This Perspective recommends key metrics and experimental details, which are suggested for reporting in ...

Constructing a Galaxy Cluster Catalog in IllustrisTNG300 Using the Mulguisin Algorithm
The Astrophysical JournalWe present a new simulated galaxy cluster catalog based on the IllustrisTNG simulation. We use the Mulguisin (MGS) algorithm to identify galaxy overdensities.

Fractional Skyrmion Tubes in Chiral‐Interfaced 3D Magnetic Nanowires
Advanced Functional Materials, EarlyView.In chiral 3D helical magnetic nanowires, the coupling between the geometric and magnetic chirality provides a way to create topological spin states like vortex tubes. Here, it is demonstrated how the breaking of this coupling in interfaced 3D nanowires of opposite chirality leads to even more complex topological spin states, such as fractional ...

Do Minihalos Affect Cosmic Reionization?
The Astrophysical JournalThe role of unresolved structures (“minihalos”) in determining the consumption of ionizing photons during cosmic reionization remains an unsolved problem in modeling cosmic reionization, despite recent extensive studies with small-box high-resolution ...

AETC: a powerful web tool to simulate astronomical images
SPIE Proceedings, 2016 We present the capabilities of the Advanced Exposure Time Calculator (AETC), a tool, publicly available via web interface (http://aetc.oapd.inaf.it/), aimed to simulate astronomical images obtained with any (given) telescope and instrument combination. The tool includes the possibility of providing an accurate modelling of PSF variations in the FoV, a ...

Merger-tree-based Galaxy Matching: A Comparative Study across Different Resolutions
The Astrophysical JournalWe introduce a novel halo/galaxy matching technique between two cosmological simulations with different resolutions, which utilizes the positions and masses of halos along their subhalo merger tree. With this tool, we conduct a study of resolution biases
