title: Satellite Methane and Ammonia Observations Consistently Show Substantial Increases in Pan-Tropical Livestock Emissions

description: The inverse analysis of atmospheric observations has become a critical tool for constraining methane (CH4) fluxes and detecting their temporal changes. However, attributing inferred CH4 fluxes to specific source sectors often relies heavily on prior information and assumptions, introducing uncertainties. Incorporating co-emitted species into top-down analyses can provide additional observational constraints for more accurate source attribution. In this study, we examine the 2010–2018 emission trends of CH4 and ammonia (NH3), both of which are emitted from the livestock sector, using satellite observations of these two gases. Our analysis reveals a strong positive correlation between CH4 and NH3 emission trends at the continental scale, mainly driven by increases in Pan-Tropical regions including South Asia, East and West Africa, North Latin America, and Brazil. This observation-derived correlation is generally consistent with changes in livestock populations. In contrast, widely used bottom-up emission inventories fail to capture this correlation, likely due to inconsistencies in the activity data used for compiling greenhouse gas and air pollutant emissions. These findings support the attribution of substantial increases in CH4 emissions to the livestock sector, identifying it as one of the major drivers for recent rises in tropical CH4 emissions.

title: Monitoring Coastal estuarine habitats for biodiversity along the temperate bioregion of South Africa

description: Coastal wetlands provide critical ecosystem services, including the enhancement of biodiversity, carbon sequestration, and flood protection. Although these ecosystems have been mapped for country-level biodiversity typing, improved extent mapping is necessary to account for estuarine dynamics and improved reporting to the Kunming-Montreal Global Biodiversity Framework (GBF) by 2030. We achieved an overall coastal wetland accuracy of 90.7% (95%) confidence interval: 90.2-91.4%) utilizing a dense time series of very high spatial resolution (3m) PlanetScope satellite imagery to map coastal wetlands with a combination of Random Forest to develop training data, U-Net convolutional neural networks, and a final decision tree to determine discrete ecosystem extents. Across the 84 mapped estuaries totaling 67,452 ha and 2,135 images, we mapped 9,131.1 ± 1,596.9 ha (13.5% of total estuarine functional zone extent) of salt marsh & reed beds and 1,718.6 ± 234.3 ha (2.5%) of Submerged Aquatic Vegetation (SAV). In addition to our earth observation analysis, we calculated tidal amplitudes and water level trends for twenty water level gauges across the region. We found tidal amplitude was a significant driver of salt marsh extent, explaining 33.6% of the variation (F(1,19) = 9.62, p = 0.005). We demonstrate a repeatable methodology for improved mapping of ecosystem zonation and utilize water level data to explore potential drivers of ecosystem distribution. Our method could be incorporated into a robust earth observation approach for reporting progress toward the goals of the/reporting to the GBF and Sustainable Development Goals (SDGs).

title: A Comprehensive Multi-Molecular Investigation of the HD 163296 Chemistry: From Observed Organics and Nitriles to Sulfates and Deuterated Species Using ALMA

description: The physical and chemical conditions within a protoplanetary disk play a crucial role in determining its chemical content, which is subsequently inherited by the forming planets. To probe these conditions, high-resolution molecular line observations coupled with accurate models are essential. In this study, we investigated the molecular chemistry of the nearby, massive, and relatively line-rich protoplanetary disk HD 163296 using high-resolution Atacama Large Millimeter/submillimeter Array (ALMA) observations across Bands 3, 4, 6, and 7. We constrained the disk-averaged and radial distribution of column density and excitation temperature for the detected molecules using our in-house retrieval code DRive. We modelled the chemistry of the disk using our in-house chemical model PEGASIS while varying initial elemental C/O ratios and cosmic ray ionisation rates. Notably, this study is the first to incorporate an extensive deuterated species network based on KIDA 2024. Our results provide the first and most stringent upper limits on the column densities of NH2CHO and HNCO in any protoplanetary disk, measuring 6.73 x 10^11 cm^-2 and 1.29 x 10^11 cm^-2, respectively. We also present the highest-resolution DCO+ emission map in the disk, revealing triple-ringed chemical substructures that closely correspond to the continuum substructures. This work establishes a strong constraint on the C/O ratio at 1.1. Our chemical models suggest that NH2CHO and HNCO primarily form on grain surfaces within the protoplanetary disk environment, with desorption processes proving insufficiently efficient to produce detectable gas-phase abundances given current ALMA capabilities.

title: Euclid Quick Data Release (Q1) A first look at a multimodal autoregressive foundation model for exploring galaxy properties

description: Modern astronomical surveys, such as the Euclid mission, produce high-dimensional, multi-modal data sets comprising imaging and spectroscopicinformation for millions of galaxies. These data sets represent an ideal benchmark for large, pre-trained, multi-modal models, offering vast amountsof unlabelled data. In this work, we present a first exploration of Euclid data with AstroPT, an autoregressive Foundation Model trained on∼ 300,000 optical and infrared Euclid images from the Q1 data release. We evaluate the benefits of self-supervised pre-training compared to fullysupervised training for tasks such as galaxy morphology classification, redshift estimation, similarity search, and outlier detection. Our findingsindicate that: (a) AstroPT embeddings are highly informative, correlating with morphology and effectively isolating outliers, (b) the addition ofinfrared data helps isolate stars but diminishes the identification of edge-on galaxies, which are better captured with optical images, (c) a simplefine-tuning of the embeddings for photometric redshift and stellar mass estimation improves accuracy, outperforming a fully supervised approachwith only ∼ 1% of the data, (d) that the addition of SED data into AstroPT via a simple multimodal token-chaining method leads to improvedresults in photo-z prediction compared to an AstroPT model pre-trained only on imagery data, and (e) anomaly detection and similarity searchalgorithms successfully identify interesting objects, such as ring galaxies and interacting galaxies.Key words.

title: Euclid preparation. 3-dimensional galaxy clustering in configuration space Part I: 2-point correlation function estimation

description: The two-point correlation function of the galaxy spatial distribution is a major cosmological observable that enables constraints on the dynamicsand geometry of the Universe. The Euclid mission aims at performing an extensive spectroscopic survey of approximately 20–30 million H-emitting galaxies up to about redshift two. This ambitious project seeks to elucidate the nature of dark energy by mapping the three-dimensionalclustering of galaxies over a significant portion of the sky. This paper presents the methodology and software developed for estimating the threedimensionaltwo-point correlation function within the Euclid Science Ground Segment. The software is designed to overcome the significantchallenges posed by the large and complex Euclid data set, which involves millions of galaxies. Key challenges include ecient pair counting,managing computational resources, and ensuring the accuracy of the correlation function estimation. The software leverages advanced algorithms,including kd-tree, octree, and linked-list data partitioning strategies, to optimise the pair-counting process. These methods are crucial forhandling the massive volume of data eciently. The implementation also includes parallel processing capabilities using shared-memory openmulti-processing to further enhance performance and reduce computation times. Extensive validation and performance testing of the software arepresented. Those have been performed by using various mock galaxy catalogues to ensure that it meets the stringent accuracy requirements of theEuclid mission. The results indicate that the software is robust and can reliably estimate the two-point correlation function, which is essential forderiving cosmological parameters with high precision. Furthermore, the paper discusses the expected performance of the software during differentstages of the Euclid Wide Survey observations and forecasts how the precision of the correlation function measurements will improve over themission’s timeline, highlighting the software’s capability to handle large data sets efficiently.Key words. large-scale structure of Universe - Cosmology: observations - Methods: statistical - Methods: data analysis

title: Euclid Quick Data Release (Q1) Extending the quest for little red dots to z 4

description: Context. Recent James Webb Space Telescope (JWST) observations have revealed an interesting population of sources with a compact morphology and a characteristic ‘v-shaped’ continuum, i.e., blue at λ 4000 Å and red at longer wavelengths. The nature of these sources, called ‘little red dots’ (LRDs), is still highly debated, as it is unclear if they host an active galactic nuclei (AGN) and their number seems to drastically drop at z 4. Aims. In this work we take advantage of the large area covered by the quick Euclid data release (Q1) to extend the search for LRDs to brighter magnitudes and to lower redshift than what has been possible with JWST. This is fundamental to have a broader view of the evolution of this peculiar galaxy population. Methods. The selection is performed by fitting the available photometric data with two power-laws, to retrieve both the rest-frame optical and UV slope consistently over a large redshift range. We then exclude extended objects, possible line-emitters, and perform a careful visual inspection to remove any remaining artifact. The combination of Euclid, IRAC, and ground-based griz data, allows us to select 16 700 LRD candidates from z = 0.12 to z = 6. Results. The resulting rest-frame UV luminosity function, in contrast with previous JWST studies, shows that the number density of LRD candidates increases from high-redshift down to z = 1.5–2.5 and decreases at even lower redshifts. The comparison with previous QSO UV luminosity functions showed that LRDs are not the dominant AGN population at z 4 and MUV −21. Follow-ups of these LRD candidates are pivotal to probe their structure and check for their compatibility with JWST sources, given that the different spatial resolution of Euclid and JWST could select different sample of compact sources.

title: Euclid: Early Release Observations - The intracluster light of Abell 2390

description: The intracluster light (ICL) provides a record of the dynamical interactions undergone by clusters, giving clues on cluster formation and evolution.Here, we analyse the properties of ICL in the massive cluster Abell 2390 at redshift z = 0.228. Our analysis is based on the deep images obtainedby the Euclid mission as part of the Early Release Observations in the near-infrared (YE, JE, HE bands), using the NISP instrument in a 0.5 deg2field. We subtracted a PSF model and removed the Galactic cirri contribution in each band after modelling it with the DAWIS software. We thenapplied three methods to detect, characterise and model the ICL and the brightest cluster galaxy (BCG): the CICLE 2D multi-galaxy fitting, theDAWIS wavelet-based multiscale software, and a mask-based 1D profile fitting. We detect ICL up to 600 kpc. The ICL fractions derived by ourthree methods range between 18 % and 36 % (average of 24 %), while the BCG+ICL fractions are between 21 % and 41 % (average of 26 %),depending on the band and method. A galaxy density map based on 219 selected cluster members shows a strong substructure to the south-eastand a smaller one to the north-west. Ellipticals dominate in the cluster’s central region, with a centroid offset from the BCG by about 70 kpc,and a distribution following that of the ICL. The comparison of the BCG+ICL, mass from gravitational lensing, and X-ray maps show that theBCG+ICL traces better substructures in the cluster. Based on colours, the ICL (out to ∼ 400 kpc) seems to be built by the accretion of smallsystems (M ∼ 109.5M⊙), or from stars coming from the outskirts of Milky Way-type galaxies (M ∼ 1010M⊙). Though Abell 2390 does not seemto be undergoing a merger, it is not yet fully relaxed, since it has accreted two groups that have not yet fully merged with the cluster core. Weestimate that the contributions to the inner 300 kpc of the ICL of the north-west and south-east subgroups are 21 % and 9 % respectively.Key words.
