Probing extreme black‐hole outflows on short timescales via high spectral‐resolution x‐ray imagers

Astronomische Nachrichten, Volume 345, Issue 6-7, July-August 2024.
Abstract We investigate outflows and the physics of super‐Eddington versus sub‐Eddington regimes in black hole systems. Our focus is on prospective science using next‐generation high‐resolution soft x‐ray instruments. We highlight the properties of black hole ultraluminous x‐ray source (ULX) systems in particular. Owing to scale invariance in accreting

Very High Redshift Radio Galaxies [PDF]

, 1999
High redshift radio galaxies (HzRGs) provide unique targets for the study of the formation and evolution of massive galaxies and galaxy clusters at very high redshifts. We discuss how efficient HzRG samples are selected, the evidence for strong morphological evolution at near-infrared wavelengths, and for jet-induced star formation in the z=3.800 HzRG ...

Flexible, Photonic Films of Surfactant‐Functionalized Cellulose Nanocrystals for Pressure and Humidity Sensing

Small Structures, Volume 5, Issue 7, July 2024.
Cellulose nanocrystals are abundant, biodegradable nanoparticles that can self‐assemble into a helical stacking that exhibits structural color. By adding a single surfactant, cellulose nanocrystals can be made compatible with apolar solvents, which are widely used for industrial coatings.

Multivariate Predictors of Lyman Continuum Escape. II. Predicting Lyman Continuum Escape Fractions for High-redshift Galaxies

The Astrophysical Journal
JWST is uncovering the properties of ever-increasing numbers of galaxies at z > 6, during the epoch of reionization. Connecting these observed populations to the process of reionization requires understanding how efficiently they produce Lyman continuum (

The Thickness of Galaxy Disks from z = 5 to 0 Probed by JWST

The Astrophysical Journal Letters
Although a thick disk is a structure prevalent in local disk galaxies and also present in our home Galaxy, its formation and evolution are still unclear.

EPOCHS. I. The Discovery and Star-forming Properties of Galaxies in the Epoch of Reionization at 6.5 < z < 18 with PEARLS and Public JWST Data

The Astrophysical Journal
We present in this paper the discovery, properties, and a catalog of 1165 high-redshift 6.5  12 in our sample and describe their properties. Finally, we note a significant observed excess of galaxies compared to models at z  > 12, revealing a tension ...
