Cosmic Reionization On Computers: Reionization Histories of Present-day Galaxies [PDF]

The Astrophysical Journal, 2019
Abstract We examine the reionization history of present-day galaxies by explicitly tracing the building blocks of halos from the Cosmic Reionization On Computers project. We track dark matter particles that belong to z = 0 halos and extract the neutral fractions at corresponding positions during rapid global reionization.

Therapeutic Implications of Biomolecular Corona on Lipid Nanoparticle‐Based Gene Delivery Systems

Small Science, Volume 5, Issue 9, September 2025.
This image illustrates the role of the biomolecular corona in lipid nanoparticles (LNPs), highlighting its impact on the stability, immune response, biodistribution, and targeted delivery. Formed after injection, the corona influences how LNPs circulate, interact with the cells, and modulate the immune response.

Asking Fast Radio Bursts for More than Reionization History

The Astrophysical Journal
We propose different estimators to probe the intergalactic medium (IGM) during the epoch of reionization (EoR) using the dispersion measure (DM) of the fast radio bursts. We consider three different reionization histories, which we can distinguish with a

The 21cm–galaxy cross-correlation: Realistic forecast for 21cm signal detection and reionisation constraints

Astronomy & Astrophysics
Context. The 21cm–galaxy cross-correlations are expected to play a key role in the confirmation of the cosmological 21cm signal. Aims. We investigate which survey configurations detect the 21cm–Lyman-α emitter (LAE) cross-correlation signal and assess ...

Simulating Reionization: Character and Observability [PDF]

AIP Conference Proceedings, 2008
In recent years there has been considerable progress in our understanding of the nature and properties of the reionization process. In particular, the numerical simulations of this epoch have made a qualitative leap forward, reaching sufficiently large scales to derive the characteristic scales of the reionization process and thus allowing for ...

Deep Space Network Radio Science and Ground‐Based Planetary Radar in the Next Decade

Radio Science, Volume 60, Issue 7, July 2025.
Abstract The Deep Space Network (DSN) has been a core operational element of NASA's crewed and robotic exploration of the Solar System since the early 1960s. The primary role of the DSN has been to acquire telemetry and navigation data, but over the years, its radiometric and radar capabilities have expanded to form a system for obtaining unique ...

Forecasts for Helium Reionization Detection with Fast Radio Bursts in the Era of Square Kilometre Array

The Astrophysical Journal
The observed dispersion measures (DMs) of fast radio bursts (FRBs) are a good indicator of the amount of ionized material along the propagation paths.

Dark-ages reionization and galaxy formation simulation V: morphology and statistical signatures of reionization [PDF]

Monthly Notices of the Royal Astronomical Society, 2016
We use the Dark-ages, Reionization And Galaxy formation Observables from Numerical Simulations (DRAGONS) framework to investigate the effect of galaxy formation physics on the morphology and statistics of ionized hydrogen (H II) regions during the Epoch of Reioinization (EoR).

MAYA (Multiple ActivitY Analyzer): An Open Access Tool to Explore Structure‐Multiple Activity Relationships in the Chemical Universe

Molecular Informatics, Volume 44, Issue 2, February 2025.
MAYA is an open chemical multiverse visualizer tool for the automated exploration of structure‐multiple activity relationships (SMARts). Abstract Herein, we introduce MAYA (Multiple Activity Analyzer), a tool designed to automatically construct a chemical multiverse, generating multiple visualizations of chemical spaces of a compound data set described
