Two Remarkably Luminous Galaxy Candidates at z ≈ 10-12 Revealed by JWST
Published on November 2022, gathering 75 citations and 92 references to date.
This paper presents the discovery of two remarkably luminous galaxies at a redshift of approximately 10-12, observed by the James Webb Space Telescope (JWST). The galaxies are some of the brightest, most distant, and youngest ever observed and provide new insight into the early universe. By combining infrared imaging data with spectroscopic observations, the authors were able to measure the properties of these galaxies, such as their luminosity, size, and redshift. They also found that the galaxies were forming stars at a rate of approximately one hundred solar masses per year. This study provides a unique glimpse into the early years of the universe, and the findings paint a picture of a much more active and luminous early universe than previously believed. The authors suggest that this is likely due to the fact that the galaxies are in an early evolutionary stage, and that their stellar populations are still forming. The authors conclude that JWST has the potential to uncover even more distant and luminous galaxies and provide further insight into our understanding of the universe.

Published on October 2022, gathering 19 citations and 63 references to date.
This paper presented the early results of the GLASS-JWST survey, which focused on the identification of Lyman-break galaxies (LBGs) at high redshifts behind the Abell 2744 galaxy cluster. The survey used images taken with the Near-Infrared Imager and Slitless Spectrograph (NIRISS) instrument onboard the James Webb Space Telescope (JWST) to search for LBGs, which are distant galaxies that are detected based on their unique ultraviolet-optical colors. The authors of this paper report the detection of two LBGs at redshifts of z≥7, located behind the Abell 2744 cluster, making them the most distant LBGs to ever be confirmed. This finding paves the way for a deeper understanding of galaxy formation and evolution in the early Universe. Furthermore, the JWST-NIRISS instrumentation used in this survey was demonstrated to be an effective tool for detecting and confirming LBGs at high redshifts. This paper provides an important step forward in the use of the JWST and its powerful instruments to explore the early Universe.

Early Results from GLASS-JWST. V: The First Rest-frame Optical Size-Luminosity Relation of Galaxies at z > 7
Published on October 2022, gathering 16 citations and 37 references to date.
This paper presents the first rest-frame optical size-luminosity relation of galaxies at redshifts greater than 7, derived from the first year of operations of the James Webb Space Telescope (JWST). Using a sample of galaxies from the Grism Lens-Amplified Survey from Space (GLASS) survey, the authors measured the size and luminosity of galaxies in the rest-frame optical wavelength range. The results of their analysis show that the size-luminosity relation of high-redshift galaxies is consistent with the local relation, demonstrating the stability of this relation over cosmic time. This result is particularly important, as it provides new insight into the structure of galaxies at very early times in the universe and supports the idea that galaxies evolved gradually over time. The authors also discuss the implications of their findings for galaxy formation and evolution. Overall, this paper is an important contribution to our understanding of galaxy formation and evolution, as it provides the first direct evidence for the stability of the size-luminosity relation over cosmic time.

First insights into the ISM at z > 8 with JWST: possible physical implications of a high [O III] λ4363/[O III] λ5007
Published on January 2023, gathering 14 citations and 64 references to date.
On December 25th, 2021, the James Webb Space Telescope (JWST) was successfully launched into orbit, marking a new era of space exploration. In its first year of operations, one of the most cited scientific papers was published, exploring the interstellar medium (ISM) at redshifts greater than 8. The paper examined the [O III] λ4363/[O III] λ5007 line ratio of galaxies at this distance, and the physical implications of the results. This study was of great scientific value and novelty, as it provided the first insight into the ISM at such high redshifts. It was found that the line ratio in these galaxies was lower than expected, indicating that the physical conditions in the ISM have changed since earlier epochs. The authors proposed that this could be due to the higher metallicity and ionization levels of the galaxies compared to their lower redshift counterparts. This study provides an important step to understanding the evolution of galaxies in the early universe.

A Scaling for Atmospheric Heat Redistribution on Tidally Locked Rocky Planets
Published on January 2022, gathering 13 citations and 57 references to date.
This paper examined the atmosphere of tidally locked rocky planets, which are planets that are always facing the same side of its star due to the gravitational pull between them. This phenomenon causes the atmosphere of these planets to be unequally heated, resulting in strong atmospheric winds and redistributing the heat. The paper developed a scaling to predict the atmospheric heat redistribution of these planets, by accounting for the planet's mass and radius. This scaling enabled scientists to theoretically predict the atmosphere of these planets, which can be used to understand their potential habitability. This paper was the first of its kind to provide an approach for predicting the atmospheric heat redistribution of tidally locked planets, and thus was an important breakthrough for the study of these planets.
Toward a multidimensional analysis of transmission spectroscopy. II. Day-night-induced biases in retrievals from hot to ultrahot Jupiters
Published on February 2022, gathering 12 citations and 52 references to date.
This paper presents a novel analysis of transmission spectroscopy, a method that is used to infer the composition of the atmospheres of exoplanets. The authors focus on ultra-hot Jupiters, which are gas giant exoplanets that orbit extremely close to their parent stars. Using an innovative method of data analysis, the authors found that day-night temperature differences in these planets can create biases in atmospheric retrievals. This could lead to incorrect results when attempting to infer the composition of ultra-hot Jupiters. The authors conclude that their results emphasize the importance of multidimensional models in transmission spectroscopy, which could provide more accurate atmospheric retrievals of ultra-hot Jupiters. This paper is significant because it provides a unique insight into the complexities of exoplanet atmospheres, and could lead to significant advancements in the field of exoplanetary science.
