Exploring Green Fluorescent Protein Brownian Motion: Temperature and Concentration Dependencies Through Luminescence Thermometry

open access: yesAdvanced Physics Research, Volume 3, Issue 11, November 2024.
This study explores Brownian motion in enhanced green fluorescent protein (EGFP) using luminescence nanothermometry. How protein concentration and temperature impact EGFP dynamics is demonstrated providing insights into protein behavior in crowded environments.

Detection of high Lyman continuum leakage from four low-redshift compact star-forming galaxies [PDF]

open access: yes, 2016
Following our first detection reported in Izotov et al. (2016), we present the detection of Lyman continuum (LyC) radiation of four other compact star-forming galaxies observed with the Cosmic Origins Spectrograph (COS) onboard the Hubble Space Telescope

The visibility of high-redshift galaxies [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 1990
The most visible galaxies (those which have the largest apparent sizes and isophotal luminosities when seen at a given distance) are those with a particular observed surface brightness. Extending this argument to high-redshift galaxies, it is clear that this optimum surface brightness moves progressively to brighter intrinsic surface brightnesses, so ...

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

open access: yesAstronomische 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

PRECISE STRONG LENSING MASS MODELING OF FOUR HUBBLE FRONTIER FIELD CLUSTERS AND A SAMPLE OF MAGNIFIED HIGH-REDSHIFT GALAXIES [PDF]

open access: yes, 2015
We conduct precise strong lensing mass modeling of four Hubble Frontier Field (HFF) clusters, Abell 2744, MACS J0416.1−2403, MACS J0717.5+3745, and MACS J1149.6+2223, for which HFF imaging observations are completed. We construct a refined sample of more

THE LONG LIVES OF GIANT CLUMPS AND THE BIRTH OF OUTFLOWS IN GAS-RICH GALAXIES AT HIGH REDSHIFT [PDF]

open access: yesAstrophysical Journal, 2013
Star-forming disk galaxies at high redshift are often subject to violent disk instability, characterized by giant clumps whose fate is yet to be understood.

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

open access: yesSmall 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.

The dust budget crisis in high-redshift submillimetre galaxies [PDF]

open access: yes, 2014
We apply a chemical evolution model to investigate the sources and evolution of dust in a sample of 26 high-redshift (z > 1) submillimetre galaxies (SMGs) from the literature, with complete photometry from ultraviolet to the submillimetre.

Ultrasensitive and Visible Detection of Influenza A Virus Based on Enzymatic Properties of Layered Gold Nanoparticles

open access: yesSmall Structures, Volume 5, Issue 4, April 2024.
An ultrasensitive and visible detection for influenza A virus is presented by leveraging the properties of gold nanoparticles (GNPs). Dual amplification, achieved through a synthetic nanoprobe utilizing the enzymatic properties of layered GNPs, exhibits a higher sensitivity. This system is suitable for point‐of‐care tests within 55 min by verifying its

THE REST-FRAME SUBMILLIMETER SPECTRUM OF HIGH-REDSHIFT, DUSTY, STAR-FORMING GALAXIES [PDF]

open access: yes, 2014
We present the average rest-frame spectrum of high-redshift dusty, star-forming galaxies from 250 to 770 GHz. This spectrum was constructed by stacking Atacama Large Millimeter/submillimeter Array (ALMA) 3 mm spectra of 22 such sources discovered by the ...
