HerMES : SPIRE galaxy number counts at 250, 350, and 500 μm [PDF]

open access: yes, 2010
Emission at far-infrared wavelengths makes up a significant fraction of the total light detected from galaxies over the age of Universe. Herschel provides an opportunity for studying galaxies at the peak wavelength of their emission.

Feasibility Study for Application of Digitized Henize Mt. Wilson Michigan Southern Sky Hα$$ \boldsymbol{\alpha} $$ Survey Low‐Dispersive Spectral Plates for Searches for Anomalous and Highly Redshifted Objects

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT The goal of this study is to confirm the feasibility of the use of digitized low dispersive MtWilson Michigan Southern Sky Hα$$ \alpha $$ survey astronomical photographic plates for modern astrophysical research. The detection of highly redshifted objects, such as early galaxies and quasars, is fundamental to understanding the universe's ...

The ORCA‐TWIN qCMOS Experiment I. Science Case and Commissioning at Calar Alto Observatory

open access: yesAstronomische Nachrichten, EarlyView.
ABSTRACT We describe a pilot study to explore a new generation of fast and low noise CMOS image sensors for time domain astronomy, using two remote telescopes with a baseline of 1635 km. The experiment involves direct imaging with novel qCMOS image sensor technology that combines fast readout with sub‐electron readout noise.

Synergistic Engineering of Oxygen Vacancies and Topological Surface States in Bi2Te3/TiO2‐X Heterostructures for Highly Efficient Photothermal‐Driven CO2 Photoreduction

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Integrating the topological insulator Bi2Te3 with oxygen‐deficient TiO2‐X creates a synergistic platform for full‐spectrum CO2 reduction, achieving high‐selectivity C2+ production via enhanced photothermal catalysis and tailored charge dynamics.
