description: V347 Aur is a young low-mass star transitioning between an evolved protostar anda cTTS that has exhibited (quasi)periodic (virgul155 days) optical outburts since2013. These optical brightenings signal the onset of rapid mass-infallsmagnetically channelled from the accretion disk onto the stellar surface whichmay also produce X-ray outbursts from star-disk magnetic interaction. We predictoptical high-state/quiescent phases in 2023 August/October that will be visiblewith XMM-Newton. We propose to obtain with EPIC (2x31 ks) the correspondingX-ray spectra to investigate any changes of the physical parameters of theemitting plasma (NH plasma temperatures and emission measures) associated withthe accretion event and the possibly enhanced star-disk magnetic interaction.

description: We propose a fulfil programme to observe a sample of optically selected dual AGNdetected in 4XMM. Key objective is the study of dual systems in early stages ofmerging showing signs of interaction on galaxy scales (40--80virgulkpc) and derivetheir properties such as absorption  spectral shape and intrinsic X-rayluminosity.We will compare the results of this study with those obtained from samples ofmergers with only one AGN in order to shed light on the possible role of thegalactic environment in triggering nuclear activity.

description: We propose to complete the exposures for four targets that are part of ourMulti-Year Heritage Programe CHEX-MATE (2018-2021) to obtain homogeneous X-raycoverage. Aiming to study the ultimate products of structure formation in massand time through observations of a large unbiased signal-to-noise limitedsample of galaxy clusters detected by Planck via theirSunyaev-Zeli??i??i??dovich effect the CHEX-MATE observations have now beenfully executed. However a number of observations were severely flared and lackmore than 30% of the requested exposure time needed to meet our data qualityrequirement.

The resulting first-time X-ray spectrum and deep image of thepulsar complemented by proposed radio observations will determine whether thispulsar is the first known product of a runaway O/B progenitor star or is amassive neutron star that has been cooled by the fast direct Urca process tobecome one of the coldest young neutron stars known.

description: X-ray data can help to better understand surface properties and atmosphericcomposition magnetospheric interactions and the geometry of neutron stars.Out of 3000 known radio pulsars only about %5-7 are detected in X-rays.Restrictingourselves to mainly bright sources or lucky finds may cause an observationalbias in particular for pulsars with low spin-down powers where possible evidencefor increased heating or non-dipole magnetic field components is observed. Wepropose a continuation of our deep legacy survey of nearby pulsars to obtaina less biased view of neutron stars X-ray properties. The proposed targets willfill in the crucial parameter space of the X-ray luminosity-spin-down power diagram which is essential to understand the physics of neutron stars and pulsars. [truncated!

description: We propose to observe two super-Eddington AGN to explore the nature ofultra-fast outflow and their geometry which are part of our spectropolarimetricsample observed with VLT-FORS2 and NTT telescopes. We aim at collecting thesample of the sources where the highly ionized outflowing medium can be studiedusing both X-ray data and spectropolarimetric data in parallel. X-ray datatraces the absorption and the viewing angle while spectropolarimetric datatraces the viewing angle and the presence of a fully ionized (outflowing)medium. Among our list of sources Mrk 1044  IRAS 04416+1215 have already showna strong highly ionized outflow in RGS spectra. We propose to observe twosources from our sample with 100 ks exposure each (200ks total) in XMM-Newton which were not observed before. [truncated! Please see actual data for full text]

Determining the relative importance of these mechanismsis important for studies of exoplanet habitability particularly around M-dwarfswhere the cumulative XUV irradiation in the habitable zone is much higher.

description: Understanding the cluster selection function is a key feature to use galaxycluster samples as cosmological probes. Thanks to the multiwavelength coverageof larger areas of the sky we are now in a position to compare galaxy clustersamples selected by independent methods to understand better their underlyingcluster population. Thanks to the eROSITA coverage of a HSC shear-selectedcluster sample we characterised their X-ray properties finding that theweak-lensing peak sample shares all properties of an X-ray selected sample.However there are three X-ray faint shear-selected clusters that lie outsideour expectations and for which we propose deeper observations to understandtheir nature and help us to understand better the X-ray and weak-lensing selection functions of galaxy clusters.

description: We propose an observation of the western edge region of W50 nebula hosting themicroquasar SS 433.It is still unclear whether W50 is produced by the interaction between the jetsand the supernova remnant of the SS 433 birth or by just the SS 433 jetsthemselves.The prime aim is to reveal the formation mechanism of W50 by distinguishingbetween thermal and non-thermal (synchrotron) emissions in the edge region ofW50.The second aim is to understand the particle acceleration processes in the jetpropagating in the nebula. We recently found a hint of particle re-acceleration occurring at the knot existing in the western jet. Using the large collecting area of XMM we make the re-acceleration clear by determining the change of the spectral slope of the synchrotron emission along the jet. [truncated!

With a new XMM-Newton observation we will explore itsspectral evolution or transient behaviour and constrain the origin of thethermal emission and the mass range of the accreting object. If confirmed as anoff-nuclear IMBH its X-ray properties will help us focus our search for thiselusive class of object relics of dwarf satellite accretion during major galaxyassembly. [truncated!

title: Rapid land cover change in agricultural valleys of the Atacama Desert, Chile

description: The profound landscape modification produced by agriculture is considered one of the main threats to biodiversity worldwide. Although the main ecological impacts are likely due to agricultural expansion into natural areas, changes in crop types and production intensification also induce significant ecological changes. We studied the land cover change process in four agricultural valleys (Lluta, Azapa, Vítor and Camarones) in the Atacama Desert of Chile between 2003 and 2019, divided into four equal periods. Using spatial data and logistic regression, we assessed the driving factors of land cover change. The Azapa valley showed the highest rate of land cover change, reaching 36.4% of netting and greenhouses landscape cover by the end of the study, and 50.4% annual rate of increase during the 2007–2011 period. Intensification was observed as the anti-aphid netting cover expanded mainly in Azapa and in the last four years in Vítor and Lluta valleys. Most land cover change was related to low slopes and elevation or sites closer to roads or surrounded by already cultivated land, like agriculture expansion on barren soil or native shrubland loss. High population density was significantly correlated with land cover change (p &lt; 0.01). If land cover change into netting continues as observed, it is possible that landscape homogenization occurs in the short term in almost all valleys. Anyway, disentangling how landscape change works and the involved drivers, could be useful to understand landscape simplification in arid lands that are under an agricultural intensification process.

title: Distribution characteristics of selenium and influencing factors in the plant–soil system of an arid oasis

description: A total of 323 topsoil samples, 63 profile soil samples, and 55 plant root samples were collected from an oasis area on the eastern margin of the Tarim Basin in China and the selenium content and other physical and chemical indicators were analyzed. The results showed that the average selenium content in the surface soil was 0.15 mg/kg, which was lower than the national background value, and only about 4% of the surveyed land area was classified as rich in selenium. The vertical distribution of selenium was characterized by surface accumulation. The organic carbon and clay content were positively correlated and the pH levels negatively correlated with the selenium content. Soil type had little effect on selenium content, though the selenium levels in Anthrosols and Gleysols were relatively high. The selenium content for cultivated land and garden soil was higher than for other land use types. The enrichment of selenium in plant roots was highest for <i>Apocynum venetum</i> L., followed by <i>Pulicaria dysenterica</i> (L.). Bernh., <i>Populus euphratica</i> Olive, <i>Tamarix chinensis</i> Lour., <i>Phragmites australis</i> (Cav.) Trin. ex Steud, and <i>Pyrus bretschneideri</i> Rehder. Correlation analysis revealed that the enrichment of selenium in the soil was mainly controlled by supergenesis in conjunction with long-distance migration and deposition. Overall, this study provides useful information for the rational development and utilization of regional land resources.
