eROSITA (extended ROentgen Survey with an Imaging Telescope Array) is the primary instrument on Spectrum-Roentgen-Gamma (SRG) mission, which was successfully launched July 13, 2019, from Baikonour cosmodrome. After commissioning of and a subsequent calibration performance verification phase, started survey entire sky December 2019. By end 2023, eight complete scans celestial sphere will have been performed, each lasting six months. At this program, all-sky in soft X-ray band (0.2--2.3\,keV)...
Context. The eROSITA X-ray telescope on board the Spectrum-Roentgen-Gamma (SRG) observatory combines a large field of view and collecting area in energy range $\sim$0.2 to $\sim$8.0 keV with capability perform uniform scanning observations sky areas. Aims. SRG/eROSITA performed $\sim$140 square degrees Final Equatorial Depth Survey (eFEDS) as part its performance verification phase. observing time was chosen slightly exceed depth equatorial fields after completion all-sky survey. We present...
The eROSITA telescope array aboard the Spektrum Roentgen Gamma (SRG) satellite began surveying sky in December 2019, with aim of producing all-sky X-ray source lists and maps an unprecedented depth. Here we present catalogues both point-like extended sources using data acquired first six months survey operations (eRASS1; completed June 2020) over half whose proprietary rights lie German Consortium. We describe observation process, analysis pipelines, characteristics sources. With nearly 930...
The evolution of the cluster mass function traces growth linear density perturbations, providing valuable insights into structures, nature dark matter, and cosmological parameters governing Universe. primary science goal eROSITA, on board Spectrum Roentgen Gamma (SRG) mission, is to constrain cosmology through function. In this paper, we present a set constraints obtained from 5259 clusters galaxies detected over an area 12791 deg 2 in western Galactic hemisphere eROSITA’s first All-Sky...
Excitation spectra of $^{11}\mathrm{C}$ are measured in the $^{12}\mathrm{C}(p,d)$ reaction near ${\ensuremath{\eta}}^{\ensuremath{'}}$ emission threshold.

Abstract Forest management faces growing uncertainty concerning environmental conditions and demand for ecosystem services. To help forest managers consider uncertainty, we applied a robust multi-criteria approach to select the optimal composition of enterprise from 12 stand types. In our simulation, strives either financial return or considering return, carbon storage stability. quantify influence climate change on these decision criteria, used concept analogous zones. Our results provide...
Excitation-energy spectra of $^{11}\mathrm{C}$ nuclei near the ${\ensuremath{\eta}}^{\ensuremath{'}}$-meson production threshold have been measured by missing-mass spectroscopy using $^{12}\mathrm{C}(p,d)$ reaction. A carbon target has irradiated with a 2.5 GeV proton beam supplied synchrotron SIS-18 at GSI to produce bound states in nuclei. Deuterons emitted ${0}^{\ensuremath{\circ}}$ reaction momentum analyzed fragment separator (FRS), used as high-resolution spectrometer. No distinct...
Discounting is standard in economics to consider time preferences of people and account for future market changes. However, so far discounting has mainly been applied monetary flows ignored many ecosystem services. In multi-objective optimization, selectively disregarding preference some non-monetary services create bias. Here we study how a range service indicators influences public planner's optimal land allocation. We used robust optimization approach model mixed forestry-avocado farm...
Growing load and deterioration of the environment can be interpreted as a result some external effects interventions. While positive externalities influence productional utilizational functions other subjects, negative ones. Both types act parcial or global externalities. Linking environmental issues to economy finance is an important sphere.
Abstract By in situ lithiation of the trifunctional amines H 3 CC(CH 2 NHSiMe ) , PhC(CH and HC{SiMe NH( p ‐Tolyl)} subsequent reaction with SnCl corresponding triamidostannates were obtained. These coupled CpM(CO) Cl (M Fe, Ru) to yield M—Sn‐bonded heterobimetallics 9–14 which NSiMe SnFe(CO) Cp ( 9 was characterized by a single‐crystal X‐ray structure analysis. Of situ‐generated amidostannates only [HC{SiMe N( Sn][Li(THF) ] 8 could be isolated as uniform product analytically spectroscopically.
The article presents the results of a study on fungi in pine-tree plantings after last great fire Notecka Forest. occurrence 134 species and 3 myxomycetes was recorded 25 permanent areas investigated between 1993 1998. particpalion bio-ecological macromycetes described context vegetation changes years following fire.
The paper presents a characterisation of the mycoflora on cupola-type rised bog in Odra river valley. characteristic each species includes: type substrate and plant community, date fruitbody occurence, forest unit, where was observed. Systematic, ecological sociological analyses have been performed protected endangered singled out.
Abstract Increased frequencies of storms and droughts due to climate change are changing central European forests more rapidly than in previous decades. To monitor these changes, multispectral 3D remote sensing (RS) data can provide relevant information for forest management inventory. In this case study, the 3D-capable satellite system ZiYuan-3 (ZY-3) were used a RS-guided inventory concept reduce field sample size compared standard grid We first pre-stratified area via ZY-3 dataset into...
