CHILES. XI. Resolved H I Morphologies and the Evolution of the H2/H I Ratio over the Last Five Billion Years

The Astrophysical Journal
We present the neutral gas morphology of four galaxies from z = 0.22 to 0.47 obtained with the COSMOS H i Large Extragalactic Survey (CHILES). The H i is resolved at the highest redshift with the 7 $\mathop{.}\limits^{\unicode{x02033}}$ 5 beam of CHILES ...

Truncation of stellar disks in galaxies at z~1

, 2004
We report here the first evidence for stellar disk truncation at high redshift, based on surface photometry of a sample of 16 high redshift (0.6 < z < 1.0) disk galaxies from the GOODS HST/ACS data.

Searching the Non‐Accreting White Dwarf Population in eROSITA Data

Astronomische Nachrichten, Volume 346, Issue 1, January 2025.
ABSTRACT eROSITA is the soft X‐ray instrument aboard the Spectrum Roentgen Gamma (SRG) satellite that is most sensitive in the energy range between 0.2 and 2.3 keV. Between December 2019 and December 2021, eROSITA completed four all‐sky surveys, producing all‐sky X‐ray source lists and sky maps of unprecedented depth.

IS THERE A MAXIMUM STAR FORMATION RATE IN HIGH-REDSHIFT GALAXIES?,,, [PDF]

, 2014
We use the James Clerk Maxwell Telescope's SCUBA-2 camera to image a 400 arcmin2 area surrounding the GOODS-N field. The 850 μm rms noise ranges from a value of 0.49 mJy in the central region to 3.5 mJy at the outside edge.

Late-time growth weakly affects the significance of high-redshift massive galaxies

The Open Journal of Astrophysics
Recent observations by the James Webb Space Telescope have revealed massive galaxies at very high redshift ($z\simeq 7-15$). The question of whether the existence of such galaxies is expected in the corresponding JWST surveys has received a lot of ...

Chiral Emission from Optical Metasurfaces and Metacavities

Advanced Photonics Research, Volume 5, Issue 12, December 2024.
Chiral emission with near‐unity degree of circular polarization and strong emission intensities is highly desirable. This review discusses recent experimental demonstrations on chiral emission from achiral emitters that are combined with patterned nanostructures.

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

Advanced 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.

Initial Results from the Nobeyama Molecular Gas Observations of Distant Bright Galaxies

, 2012
We present initial results from the CO survey toward high redshift galaxies using the Nobeyama 45m telescope. Using the new wide bandwidth spectrometer equipped with a two-beam SIS receiver, we have robust new detections of three high redshift (z=1.6-3.4)

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
