Broad-band spectrophotometry of the hot Jupiter HAT-P-12b from the near-UV to the near-IR

The detection of trends or gradients in the transmission spectrum of extrasolar planets is possible with observations at very low spectral resolution. Transit measurements of sufficient accuracy using selected broad-band filters allow for an initial characterization of the atmosphere of the planet. We obtained time series photometry of 20 transit events and analyzed them homogeneously, along with eight light curves obtained from the literature. In total, the light curves span a range from 0.35 to 1.25 microns. During two observing seasons over four months each, we monitored the host star to constrain the potential influence of starspots on the derived transit parameters. We rule out the presence of a Rayleigh slope extending over the entire optical wavelength range, a flat spectrum is favored for HAT-P-12b with respect to a cloud-free atmosphere model spectrum. A potential cause of such gray absorption is the presence of a cloud layer at the probed latitudes. Furthermore, in this work we refine the transit parameters, the ephemeris and perform a TTV analysis in which we found no indication for an unseen companion. The host star showed a mild non-periodic variability of up to 1%. However, no stellar rotation period could be detected to high confidence.Comment: 13 pages, 6 figures, Accepted for publication in A&

Om illegal jakt i Fennoskandia

Ett ökat missnöje bland delar av landsbygdsbefolkningen och jägarsamhället gentemot bevarandepolitiken för stora rovdjur har påverkat den sociopolitiskt motiverade illegala jakten på dessa arter. Denna typ av jaktbrott har legat som grund för undersökningen i ett tvärvetenskapligt internationellt samarbetsprojekt lett av forskare vid Sveriges lantbruksuniversitet, vid Ultuna. Efter tre år av djupintervjuer med jägare, en enkätundersökning, jämförelser med andra delar av världen och nära samarbete med forskare i Fennoskandia avslutades projektet 2016. Föreliggande rapport fullbordar resultatförmedlingen och den avslutande diskussionen omkring forskningsresultaten från projektet och ger samtidigt uppslag för framtida forskning. För första gången presenterades hela projektet och dess medlemmar för en publik bestående av praktiker och intressegrupper runt jakt. Rapporten sammanfattar på detta sätt två dagars temadiskussioner i en workshop med 45 representanter från olika samhällssektorer, bland annat jägare- jordbruks- och naturskyddsorganisationer, länsstyrelser, Naturvårdsverket, polis och åklagare som de ser ut i länderna som utgör Fennoskandia: Sverige, Norge, Danmark och Finland. Diskussionerna handlade om social kontroll och illegal jakt, att flytta viltförvaltningen till domstolarna, EUs inflytande och olika plattformar för att förebygga illegal jakt, speciellt på stora rovdjur, som vargar. Rapporten riktar sig till både forskare och praktiker som möter problem med social accepterade, men hemliga och gömda, former av illegal jakt som i sin tur beror av statsapparatens legitimitetskris, misstro mot politik och politiker och som också är en manifestation för landsbygdens motstånd i ett modernt samhälle.The following report marks the dissemination and discussion of the research results and insights for future research produced by this project. Hence, it represents the first time the full research project and its members stand before the public and interest groups. The report synthesizes two days of workshop thematic discussions between 45 participants from societal sectors including hunting and nature conservation NGOs, county administrative boards, Environmental Protection Agencies, law enforcement, environmental attorneys and farming associations as they feature across the Fennoscandian countries: Sweden, Norway, Denmark and Finland. Its discussions center on social control in wildlife crime, the juridification of hunting issues, the influence of the EU and platforms for going forward to mitigate poaching, in particular of large carnivores like the wolf. The report is an essential read for both researchers and practitioners faced with the problem of socially accepted, but secretive and hidden, forms of illegal hunting in response to governmental legitimacy crises, distrust of policy and policy-makers, and as a manifestation of rural resistance in modernity

On illegal killings of wildlife in Fennoscandia

Rising levels of discontent among rural residents and parts of the hunting community toward large carnivore conservation policy has effected a phenomenon of socio-politically motivated illegal killing of these unpopular species. Such wildlife crime formed the investigation of an interdisciplinary and internationally collaborative research project headed by the Swedish University of Agricultural Sciences in Ultuna, Uppsala. Through 3 years of in-depth interview studies with hunters in Sweden, a quantitative survey to hunters, comparative studies in other parts of the world and close collaboration with Fennoscandian researchers and practitioners, this project ran to completion at the end of 2016. The following report marks the dissemination and discussion of the research results and insights for future research produced by this project. Hence, it represents the first time the full research project and its members stand before the public and interest groups.

Green criminology: shining a critical lens on environmental harm

Green criminology provides for inter-disciplinary and multi-disciplinary engagement with environmental crimes and wider environmental harms. Green criminology applies a broad ‘‘green’’ perspective to environmental harms, ecological justice, and the study of environmental laws and criminality, which includes crimes affecting the environment and non-human nature. Within the ecological justice and species justice perspectives of green criminology there is a contention that justice systems need to do more than just consider anthropocentric notions of criminal justice, they should also consider how justice systems can provide protection and redress for the environment and other species. Green criminological scholarship has, thus, paid direct attention to theoretical questions of whether and how justice systems deal with crimes against animals and the environment; it has begun to conceptualize policy perspectives that can provide contemporary ecological justice alongside mainstream criminal justice. Moving beyond mainstream criminology’s focus on individual offenders, green criminology also explores state failure in environmental protection and corporate offending and environmentally harmful business practices. A central discussion within green criminology is that of whether environmental harm rather than environmental crime should be its focus, and whether green ‘‘crimes’’ should be seen as the focus of mainstream criminal justice and dealt with by core criminal justice agencies such as the police, or whether they should be considered as being beyond the mainstream. This article provides an introductory overview that complements a multi- and inter-disciplinary article collection dedicated to green criminological thinking and research

Tess data for asteroseismology: Timing verification

The Transiting Exoplanet Survey Satellite (TESS) is NASA´s latest space telescope dedicated to the discovery of transiting exoplanets around nearby stars. Besides the main goal of the mission, asteroseismology is an important secondary goal and very relevant for the high-quality time series that TESS will make during its two-year all-sky survey. Using TESS for asteroseismology introduces strong timing requirements, especially for coherent oscillators. Although the internal clock on board TESS is precise in its own time, it might have a constant drift. Thus, it will need calibration, or else offsets might inadvertently be introduced. Here, we present simultaneous ground- and space-based observations of primary eclipses of several binary systems in the Southern ecliptic hemisphere, used to verify the reliability of the TESS timestamps. From 12 contemporaneous TESS/ground observations, we determined a time offset equal to 5.8 ± 2.5 s, in the sense that the barycentric time measured by TESS is ahead of real time. The offset is consistent with zero at the 2.3σ level. In addition, we used 405 individually measured mid-eclipse times of 26 eclipsing binary stars observed solely by TESS in order to test the existence of a potential drift with a monotonic growth (or decay) affecting the observations of all stars. We find a drift corresponding to σ drift = 0.009 ± 0.015 s day-1. We find that the measured offset is of a size that will not become an issue for comparing ground-based and space data for coherent oscillations for most of the targets observed with TESS.Fil: Essen, Carolina von.

Weight Consistency Specifies Regularities of Macaque Cortical Networks

To what extent cortical pathways show significant weight differences and whether these differences are consistent across animals (thereby comprising robust connectivity profiles) is an important and unresolved neuroanatomical issue. Here we report a quantitative retrograde tracer analysis in the cynomolgus macaque monkey of the weight consistency of the afferents of cortical areas across brains via calculation of a weight index (fraction of labeled neurons, FLN). Injection in 8 cortical areas (3 occipital plus 5 in the other lobes) revealed a consistent pattern: small subcortical input (1.3% cumulative FLN), high local intrinsic connectivity (80% FLN), high-input form neighboring areas (15% cumulative FLN), and weak long-range corticocortical connectivity (3% cumulative FLN). Corticocortical FLN values of projections to areas V1, V2, and V4 showed heavy-tailed, lognormal distributions spanning 5 orders of magnitude that were consistent, demonstrating significant connectivity profiles. These results indicate that 1) connection weight heterogeneity plays an important role in determining cortical network specificity, 2) high investment in local projections highlights the importance of local processing, and 3) transmission of information across multiple hierarchy levels mainly involves pathways having low FLN values
