The article deals with information and analytical support of sustainable development of an economic entity. The solution of the research questions required the use of the following General theoretical research methods: abstraction and concretization, analysis and synthesis, induction and deduction, comparison and contrast. The article presents the basic principles of developing a methodology for information and analytical support of sustainable development of an economic entity within the framework of a stakeholder approach. The proposed methodology is divided into seven consecutive stages, the content of the analysis within the framework of the methodology is determined by the socio-economic essence of stakeholders, their interests and the expected effectiveness of methodologically competent disclosure of information to them. From the point of view of a systematic approach to management, information and analytical support is integrated into the strategic management system of an economic entity. As part of the process approach, the methodology of information and analytical support is considered based on the overall priority of reporting elements to stakeholders.

This warm Jupiter was first detected and identified as a promising candidate from a search for single-transit signals in TESS Sector 20 data, and was later characterized as a planet following two subsequent transits (TESS Sectors 26 and 53) and follow-up ground-based RV observations with the NEID and SOPHIE spectrographs. We jointly fit the transit and RV data to constrain the physical (

), TOI-4127 b is a compelling candidate for studies of warm Jupiter populations and of hot Jupiter formation pathways. We show that the present periastron separation of TOI-4127 b is too large for high-eccentricity tidal migration to circularize its orbit, and that TOI-4127 b is unlikely to be a hot Jupiter progenitor unless it is undergoing angular momentum exchange with an undetected outer companion. Although we find no evidence for an external companion, the available observational data are insufficient to rule out the presence of a perturber that can excite eccentricity oscillations and facilitate tidal migration.
Hydrodynamics and Nucleosynthesis of Jet-driven Supernovae. I. Parameter Study of the Dependence on Jet Energetics
Authors: Leung Shing-Chi , Nomoto Ken’ichi , Suzuki Tomoharu 
Published: May 2023

Abstract
Rotating massive stars with initial progenitor masses M
prog ∼ 25–140 M
⊙ can leave rapidly rotating black holes to become collapsars. The black holes and the surrounding accretion disks may develop powerful jets by magnetohydrodynamics instabilities. The propagation of the jet in the stellar envelope provides the necessary shock heating for triggering nucleosynthesis unseen in canonical core-collapse supernovae. However, the energy budget of the jet and its effects on the final chemical abundance pattern are unclear. In this exploratory work, we present a survey on the parameter dependence of collapsar nucleosynthesis on jet energetics. We use the zero-metallicity star with M
prog ∼ 40 M
⊙ as the progenitor. The parameters include the jet duration, its energy deposition rate, deposited energy, and the opening angle. We examine the correlations of the following observables: (1) the ejecta and remnant masses; (2) the energy deposition efficiency; (3) the 56Ni production and its correlation with the ejecta velocity, deposited energy, and the ejected mass; (4) the Sc–Ti–V correlation as observed in metal-poor stars; and (5) the [Zn/Fe] ratio as observed in some metal-poor stars. We also provide the chemical abundance table of these explosion models for the use of the galactic chemical evolution and stellar archeology.
Detailed Shapes of the Line-of-sight Velocity Distributions in Massive Early-type Galaxies from Nonparametric Spectral Models

Published: May 2023

Abstract
We present the first systematic study of the detailed shapes of the line-of-sight velocity distributions (LOSVDs) in nine massive early-type galaxies (ETGs) using the novel nonparametric modeling code WINGFIT. High-signal spectral observations with the Multi-Unit Spectroscopic Explorer (MUSE) at the Very Large Telescope allow us to measure between 40 and 400 individual LOSVDs in each galaxy at a signal-to-noise ratio level better than 100 per spectral bin and to trace the LOSVDs all the way out to the highest stellar velocities. We extensively discuss potential LOSVD distortions due to template mismatch and strategies to avoid them. Our analysis uncovers a plethora of complex, large-scale kinematic structures for the shapes of the LOSVDs. Most notably, in the centers of all ETGs in our sample, we detect faint, broad LOSVD “wings” extending the line-of-sight velocities, v
los, well beyond 3σ to v
los ∼ ± 1000–1500 km s−1 on both sides of the peak of the LOSVDs. These wings likely originate from point-spread function effects and contain velocity information about the very central unresolved regions of the galaxies. In several galaxies, we detect wings of similar shape also toward the outer parts of the MUSE field of view. We propose that these wings originate from faint halos of loosely bound stars around the ETGs, similar to the cluster-bound stellar envelopes found around many brightest cluster galaxies.

Abstract
The arrival time prediction of coronal mass ejections (CMEs) is an area of active research. Many methods with varying levels of complexity have been developed to predict CME arrival. However, the mean absolute error (MAE) of predictions remains above 12 hr, even with the increasing complexity of methods. In this work we develop a new method for CME arrival time prediction that uses magnetohydrodynamic simulations involving data-constrained flux-rope-based CMEs, which are introduced in a data-driven solar wind background. We found that for six CMEs studied in this work the MAE in arrival time was ∼8 hr. We further improved our arrival time predictions by using ensemble modeling and comparing the ensemble solutions with STEREO-A and STEREO-B heliospheric imager data. This was done by using our simulations to create synthetic J-maps. A machine-learning (ML) method called the lasso regression was used for this comparison. Using this approach, we could reduce the MAE to ∼4 hr. Another ML method based on the neural networks (NNs) made it possible to reduce the MAE to ∼5 hr for the cases when HI data from both STEREO-A and STEREO-B were available. NNs are capable of providing similar MAE when only the STEREO-A data are used. Our methods also resulted in very encouraging values of standard deviation (precision) of arrival time. The methods discussed in this paper demonstrate significant improvements in the CME arrival time predictions. Our work highlights the importance of using ML techniques in combination with data-constrained magnetohydrodynamic modeling to improve space weather predictions.
Star Formation and Molecular Gas Diagnostics with Mid- and Far-infrared Emission
Authors: Whitcomb C. M. , Sandstrom K. , Leroy A. , Smith J.-D. T. 
Published: May 2023

Abstract
With the start of JWST observations, mid-infrared (MIR) emission features from polycyclic aromatic hydrocarbons (PAHs), H2 rotational lines, fine structure lines from ions, and dust continuum will be widely available tracers of gas and star formation rate (SFR) in galaxies at various redshifts. Many of these tracers originate from dust and gas illuminated by UV photons from massive stars, so they generally trace both SFR and gas to varying degrees. We investigate how MIR spectral features from 5–35 μm and photometry from 3.4–250 μm correlate with SFR and molecular gas. In general, we find MIR emission features (i.e., PAHs and H2 rotational lines) trace both CO and SFR better than CO and SFR trace one another. H2 lines and PAH features correlate best with CO. Fine structure lines from ions correlate best with SFR. The [S iii] lines at 18.7 and 33.5 μm, in particular, have a very tight correlation with SFR, and we use them to calibrate new single-parameter MIR tracers of SFR that have negligible metallicity dependence in our sample. The 17 μm/7.7 μm PAH feature ratio increases as a function of CO emission which may be evidence of PAH growth or neutralization in molecular gas. The degree to which dust continuum emission traces SFR or CO varies as a function of wavelength, with continuum between 20 and 70 μm better tracing SFR, while longer wavelengths better trace CO.
Exploring the Emission Mechanisms of Mrk 180 with Long-term X-Ray and γ-Ray Data
Authors: Mondal Sandeep Kumar , Das Saikat , Gupta Nayantara 
Published: May 2023

Abstract
Markarian (Mrk) 180 is a BL Lacertae object located at a redshift of 0.045 and is a potential candidate for high-energy cosmic-ray acceleration. We have analyzed the Fermi Large Area Telescope (Fermi-LAT) γ-ray data of Mrk 180 collected over a period of 12.8 yr and found no significant enhancement in the flux from the long-term γ-ray light curve. We have also analyzed Swift X-ray, ultraviolet, and optical, and X-ray Multi-Mirror Mission (XMM-Newton) data to construct the multiwavelength spectral energy distribution (SED). The SED has been modeled with one-zone pure leptonic and lepto-hadronic scenarios to explain the underlying physics of multiwavelength emission. The pure leptonic model and the two lepto-hadronic models, viz., (i) line-of-sight interactions of ultrahigh-energy cosmic rays (UHECRs; E ≳ 1017 eV) with the cosmic background radiation and (ii) the interactions of relativistic protons with the cold protons in the jet, have been compared in our work. Moreover, an earlier study has associated Mrk 180 with the Telescope Array (TA) hotspot of UHECRs at E > 57 EeV. This speculation motivates us to check whether ultrahigh-energy protons and iron nuclei can reach the Earth from Mrk 180. After comparing the results of our simulation with the current observational data, we find that Mrk 180 is unlikely to be a source of the UHECR events contributing to the TA hotspot for conservative strengths of extragalactic magnetic fields.
A Young White Dwarf Orbiting PSR J1835−3259B in the Bulge Globular Cluster NGC 6652

Abstract
We report on the discovery of the companion star to the millisecond pulsar PSR J1835−3259B in the Galactic globular cluster NGC 6652. Taking advantage of deep photometric archival observations acquired through the Hubble Space Telescope in near-UV and optical bands, we identified a bright and blue object at a position compatible with that of the radio pulsar. The companion is located along the helium-core white dwarf cooling sequence, and the comparison with binary evolution models provides a mass of 0.17 ± 0.02 M
⊙, a surface temperature of 11,500 ± 1900 K, and a very young cooling age of only 200 ± 100 Myr. The mass and the age of the companion are compatible with a progenitor star of about 0.87 M
⊙, which started transferring mass to the primary during its evolution along the subgiant branch and stopped during the early red giant branch phase. Combining together the pulsar mass function and the companion mass, we found that this system is observed at an almost edge-on orbit and hosts a neutron star with a mass of 1.44 ± 0.06 M
⊙, thus suggesting a highly nonconservative mass accretion phase. The young age of the WD companion is consistent with the scenario of a powerful, relatively young MSP indicated by the earlier detection of gamma-rays from this system.
Paschen-line Constraints on Dust Attenuation and Star Formation at z ∼ 1–3 with JWST/NIRSpec
Authors: Reddy Naveen A. , Topping Michael W. , Sanders Ryan L. , Shapley Alice E. , Brammer Gabriel 
Published: May 2023

Abstract
We use medium-resolution JWST/NIRSpec observations from the Cosmic Evolution Early Release Science Survey to place the first constraints on dust attenuation and star formation based on Paschen lines for a sizable sample of 63 galaxies at redshifts z = 1.0–3.1. Our analysis indicates strong correlations between the Balmer decrement, Hα/Hβ, and line ratios that include Paschen lines (i.e., Paα/Hβ, Paβ/Hβ, and the Paschen decrement, Paα/Paβ), suggesting that the former is sensitive to the overall dust obscuration toward H ii regions in high-redshift galaxies. The line ratios are used to derive nebular reddening, E(B − V)neb, and star formation rates (SFRs). There is marginal evidence that the SFRs deduced from Paschen lines may exceed by ≈25% those derived from Balmer lines alone, suggesting the presence of star formation that is optically thick in Balmer lines, though deeper observations are needed to confirm this result. Using the Paschen-line constraints on the bolometric SFRs, we reevaluate the relationship between dust obscuration and UV spectral slope, and find a reddening of the UV continuum that, on average, follows the SMC extinction curve. This analysis highlights the need for deeper spectroscopy of more representative samples to evaluate nebular dust attenuation and bolometric SFRs in high-redshift galaxies, and their relationship to the reddening of the UV continuum.
The role of community science in orthopteran research
Authors: Byerly Amy R. , Firneno Jr. Thomas J. , Beard Riley , Larson Erica L. 
Published: May 2023

Orthopterans are commonly encountered in rural, suburban, and urban landscapes and have charismatic songs that attract the public’s attention. These are ideal organisms for connecting the public with science and critical concepts in ecology and evolution, such as habitat conservation and climate change. In this review, we provide an overview of community science and review community science in orthopterans. Best practices for orthopteran community science are provided, with a focus on audio recordings and highlighting new ways in which scientists who study orthopterans can engage in community science.
Before the modern era, scientific discovery was commonly made by people who were not scientists by profession (Brenna 2011, Miller-Rushing et al. 2012). This began to change in the middle of the nineteenth century when science became highly academic, with greater “gatekeeping” of knowledge, and data collection became increasingly expensive. As a result, much of the knowledge gained during that time has been effectively withheld from non-scientists in difficult-to-obtain scientific journals, and there were few opportunities for the public to directly engage with scientific research. In recent years, there has been a concerted effort from the scientific community to change the way we engage with the public. These “citizen” or “community” science projects are filling gaps in the modern approach to scientific inquiry (Jordan et al. 2012, Toomey and Domroese 2013, Johnson et al. 2014). Here, we provide an overview of community science and highlight the exciting and unique role that community science can play in orthopteran research. We focus on how acoustic surveys can be used to study orthopteran biodiversity, provide best practices for orthopteran community science, and suggest future avenues for research.
Où se situent les centres sociaux ? Une histoire entre action sociale et éducation populaire
Authors: Louis Jérémy 
Published: May 2023

Cet article aborde la manière dont les centres sociaux et la Fédération des centres sociaux et socioculturels de France définissent et mettent en place leurs objectifs politiques à travers leur histoire. Il donne à voir les référentiels dans lesquels s’inscrivent les salarié·es et bénévoles de ce réseau. Il donne ainsi une profondeur historique à ce que l’on envisage dans ce dossier comme le « politique des centres sociaux ». L’analyse croise les représentations des centres sociaux qui circulent au travers de leur histoire avec une approche sociohistorique des conditions d’activité de ces structures. Trois périodes sont ainsi étudiées : les premières résidences sociales au tournant du XX e siècle, l’inscription dans une politique nationale d’animation socioculturelle dans les années 1960-1970, et le passage à la logique de projet depuis les années 1980. En définitive, l’article rend compte d’une action située entre action sociale et éducation populaire avec des objectifs centrés sur la promotion de la paix sociale et la création de formes de solidarités locales. Néanmoins, ces référentiels dominants au sein du réseau entrent en tension avec des discours et des pratiques qui positionnent les centres sociaux comme acteurs de démocratie, notamment depuis les années 2000.
Les représentations de la citoyenneté dans les centres sociaux, une « épistémologie civique » en tension avec le « développement du pouvoir d’agir » ?
Authors: Neveu Catherine 
Published: May 2023

De nombreux travaux sociologiques ont analysé les formes « d’évitement du politique » dans le monde associatif. S’il s’intéresse globalement à des problématiques similaires, cet article aborde les enjeux politiques dans ces espaces à partir d’un autre angle d’analyse : celui d’une approche anthropologique des processus de citoyenneté. Il s’attachera donc dans un premier temps, à partir d’une enquête multisituée et de longue durée, à décrire et analyser le régime dominant de citoyenneté dans le réseau des centres sociaux, ce qu’on pourrait définir comme une « épistémologie civique » spécifique. L’introduction, au début des années 2010, de la visée de « développement du pouvoir des habitants » est venue au moins en partie révéler ce régime dominant, mais le plus souvent implicite, de citoyenneté. En saisissant comment cette visée entre en tension avec cette « épistémologie civique » stabilisée, on peut mieux comprendre pourquoi et comment (et c’est l’objet de la seconde partie de l’article) certaines dimensions de ce « pouvoir d’agir » ont fait l’objet d’appropriations locales assez aisées, alors que d’autres se confrontent à plus de résistance.
Entre-soi et rapports sociaux dans les centres sociaux. Une participation « sous contrôle » des femmes des quartiers
Authors: Garnier Julie , Rétif Sarah 
Published: May 2023

Cet article analyse la façon dont les salarié·es et les bénévoles de centres sociaux interprètent les demandes habitantes en tenant compte des rapports sociaux, entendus ici dans une acception élargie selon laquelle chaque individu se situe au croisement de rapports de pouvoir. L’article prend l’exemple de demandes de femmes musulmanes faites à un centre social situé dans la région Centre-Val de Loire d’organiser une fête à caractère religieux ou de créer un cours de langue arabe, et analyse des situations où des femmes de toutes origines sociales ou ethniques, et de toutes générations, sont réunies par le centre social autour d’une même activité de discussion. Les matériaux mobilisés sont tirés de deux enquêtes ethnographiques, conduites entre 2017 et 2020 dans le cadre du projet de recherche Engagir, et principalement sur deux espaces d’entre-soi féminin : un groupe de parole et un cours de langue arabe dans des quartiers populaires de Tours et de la périphérie d’Orléans. Dans ces situations, la non-mixité de genre semble d’autant plus acceptée par les équipes qu’elle s’accommode des impératifs de la participation des publics, de la mixité sociale et de la laïcité.
