The Astrophysical Journal, 2023 We use large simulations of Ly α emitters with different fractions of ionized intergalactic medium to quantify the clustering of Ly α emitters as measured by the void probability function (VPF), and how it evolves under different ionization scenarios. We

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 ...

Uncovering the Origin of Efficiency Roll‐Off in TADF OLEDs
Advanced Functional Materials, EarlyView.OLEDs based on thermally activated delayed fluorescent (TADF) materials often suffer from a severe drop in efficiency at high brightness levels. This work presents a technique to uncover the source of this efficiency drop, and quantifies the exciton‐exciton and exciton‐polaron annihilation processes responsible for efficiency losses in our TADF OLEDs ...

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

Advanced Functional Materials, EarlyView.Two pyridinium‐based ionic liquid templated hybrid manganese halides, (C4Py)2[MnCl4] and (C4Py)2[MnBr4], display similar bulk structures but show significantly different photoluminescence behaviors due to the bromine heavy‐atom effect. Their stable local Mn environments remain intact even in the molten state, allowing applications such as luminescence ...

A Coscaling Grid for Athena++. II. Magnetohydrodynamics
The Astrophysical Journal Supplement SeriesWe extend the coscaling formalism of Habegger & Heitsch implemented in Athena++ to magnetohydrodynamics. The formalism relies on flow symmetries in astrophysical problems involving expansion, contraction, and center-of-mass motion. The formalism is fully

Advanced Functional Materials, EarlyView.Gold bipyramids can act as efficient plasmonic nanoheaters, but they often reshape during laser heating. This study shows that oxygen nanobubbles drive oxidative etching and that surface ligands control stability. CTAB‐ and citrate‐coated particles blunt and lose optical performance, whereas polystyrene sulfonate preserves shape and heating by ...

Not So Heavy Metals: Black Hole Feedback Enriches The Circumgalactic Medium [PDF]
, 2018 We examine the effects of SMBH feedback on the CGM using a cosmological hydrodynamic simulation \citep[{\sc Romulus25};][]{Tremmel2017} and a set of four zoom-in `genetically modified' Milky Way-mass galaxies sampling different evolutionary paths.
