Searching for high-z DSFGs with NIKA2 and NOEMA [PDF]

EPJ Web of Conferences, 2022
As the possible progenitors of passive galaxies at z=2-3, dusty starforming galaxies (DSFGs) at z>4 provide a unique perspective to study the formation, assembly, and early quenching of massive galaxies in the early Universe.

The Extinction Law in High‐Redshift Galaxies [PDF]

The Astrophysical Journal, 2004
We estimate the dust extinction laws in two intermediate redshift galaxies. The dust in the lens galaxy of LBQS1009-0252, which has an estimated lens redshift of zl~0.88, appears to be similar to that of the SMC with no significant feature at 2175 A.

Modelling galaxy clustering at high redshift [PDF]

Monthly Notices of the Royal Astronomical Society, 1998
We discuss the theoretical interpretation of observational data concerning the clustering of galaxies at high redshifts. Building on the theoretical machinery developed by Matarrese et al. (1997), we make detailed quantitative predictions of galaxy clustering statistics for a variety of cosmological models, taking into account differences in spatial ...

High Redshift Radio Galaxies with the VLT [PDF]

, 1997
The study of high-$z$ radio galaxies (HZRGs) has matured considerably during the last decade. Large numbers of $z>2$ radio galaxies have been found and have been studied in considerable detail. In this review we will address the importance of the VLT for studies of samples of distant radio galaxies.

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

Astronomische Nachrichten, Volume 347, Issue 7, August 2026.
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.

Unveiling the Cosmic Chemistry. II. “Direct” Te-based Metallicity of Galaxies at 3 < z < 10 with JWST/NIRSpec

The Astrophysical Journal
We report the detection of the [O iii ] auroral line in 42 galaxies within the redshift range of 3 < z < 10. These galaxies were selected from publicly available JWST data releases, including the JADES and PRIMAL surveys, and observed using both the low ...

Seedless One‐Pot Synthesis of Colloidal InAs Quantum Dots Enabling a High‐Accuracy Photoplethysmography Oximeter

Advanced Science, Volume 13, Issue 38, 9 July 2026.
A real‐time, non‐contact photoplethysmography (PPG) system based on InAs colloidal quantum dots (CQDs) synthesized via a seedless injection synthesis is demonstrated. The measured oxygen saturation shows considerable agreement with commercial PPG devices.

Simulating High-redshift Galaxies: Enhancing UV Luminosity with Star Formation Efficiency and a Top-heavy IMF

The Astrophysical Journal
Recent findings from photometric and spectroscopic JWST surveys have identified examples of high-redshift galaxies at z  ≳ 10. These high- z galaxies appear to form much earlier and exhibit greater UV luminosity than predicted by theoretical work.

An Empirical Consistent Redshift Bias: A Possible Direct Observation of Zwicky’s TL Theory

Particles
Recent advancements have shown tensions between observations and our current understanding of the Universe. Such observations may include the H0 tension and massive galaxies at high redshift that are older than traditional galaxy formation models have ...
