description: We experimentally demonstrate hyperfine optical pumping of rubidium atoms probed by an evanescent electromagnetic field at a dielectric-vapor interface. This light-atom interaction at the nanoscale is investigated using a right angle prism integrated with a vapor cell and excited by evanescent wave under total internal reflection. An efficient hyperfine optical pumping, leading to a complete suppression of absorption on the probed evanescent signal, is observed when a pump laser beam is sent at normal incidence to the interface. In contrast, when the pump and probe beams are co-propagating in the integrated prism-vapor cell, no clear evidence of optical pumping is observed. The experimental results are supported by a detailed model based on optical Bloch equation of a four atomic levels structure. The obtained on-chip highly efficient optical pumping at the nanoscale is regarded as an important step in the quest for applications such as optical switching, magnetometry and quantum memory.

title: Macroprudential FX Regulations: Shifting the Snowbanks of FX Vulnerability?

description: Can macroprudential foreign exchange (FX) regulations on banks reduce the financial and macroeconomic vulnerabilities created by borrowing in foreign currency? To evaluate the effectiveness and unintended consequences of macroprudential FX regulations, we develop a parsimonious model of bank and market lending in domestic and foreign currency and derive four predictions. We confirm these predictions using a rich data set of macroprudential FX regulations. These empirical tests show that FX regulations (1) are effective in terms of reducing borrowing in foreign currency by banks; (2) have the unintended consequence of simultaneously causing firms to increase FX debt issuance; (3) reduce the sensitivity of banks to exchange rate movements; but (4) are less effective at reducing the sensitivity of corporates and the broader financial market to exchange rate movements. As a result, FX regulations on banks appear to be successful in mitigating the vulnerability of banks to exchange rate movements and the global financial cycle, but partially shift the snowbank of FX vulnerability to other sectors.
description: La réglementation macroprudentielle des changes applicable aux banques peut-elle réduire les vulnérabilités financières et macroéconomiques découlant des emprunts en devises? Afin d’évaluer l’efficacité et les conséquences imprévues de cette réglementation, nous avons conçu un modèle parcimonieux des opérations de prêt en monnaie nationale et en devises effectuées par les banques et sur les marchés. Ce modèle nous permet de formuler quatre hypothèses, que nous confirmons au moyen d’un riche ensemble de données sur la réglementation macroprudentielle des changes. Ces tests empiriques indiquent que celle-ci : 1) fait baisser les emprunts en devises contractés par les banques, 2) a pour effet inattendu d’augmenter simultanément l’émission de titres d’emprunt en devises par les entreprises, 3) réduit la sensibilité des banques aux fluctuations du taux de change, mais 4) est moins susceptible de réduire celle des sociétés et de l’ensemble des marchés financiers. La réglementation des changes imposée aux banques semble donc réussir à atténuer la vulnérabilité des institutions aux mouvements de change et au cycle financier mondial. Toutefois, elle tend à transférer une partie de la vulnérabilité à ces mouvements vers d’autres secteurs.
title: Calibrating the Magnitude of the Countercyclical Capital Buffer Using Market-Based Stress Tests
Creators: name: van Oordt, Maarten
Publisher: name: Bank of Canada
Year: 2018

description: Banking regulation maintains the stability of the overall banking system. The countercyclical capital buffer helps to achieve this objective.

The banking system needs to be well-capitalized to support the flow of credit in the economy. The objective of the countercyclical capital buffer is to ensure the banking sector is sufficiently well-capitalized during the period of financial stress that could occur after a credit expansion. To achieve this, authorities can require the buildup of additional capital during periods of strong credit growth. The additional capital—called the countercyclical capital buffer—can then support credit growth when the economy faces challenging economic conditions.

How much bank capital would be enough to account for these cyclical variations is a difficult question. This paper proposes a new way to estimate the level of the countercyclical capital buffer required. The paper’s approach uses historical stock market data to carry out automated market-based stress tests on the banking system. These stress tests help estimate the size of capital buffers necessary to absorb severe but plausible shocks. They can be done retroactively to estimate the impact of severe shocks to the banking system during periods of strong and weak credit growth. The difference sheds light on the amount of capital required to offset the cyclical variations in risks.
description: La réglementation des banques assure la stabilité de l’ensemble du système bancaire, et le volant de fonds propres contracyclique aide à atteindre cet objectif.

Le système bancaire doit être bien capitalisé pour soutenir les flux de crédit au sein de l’économie. Le volant contracyclique vise à ce que le secteur bancaire soit suffisamment capitalisé durant les périodes de tensions financières qui pourraient survenir après une expansion du crédit. Pour ce faire, les autorités peuvent exiger que les institutions accumulent un supplément de fonds propres pendant les périodes de forte croissance du crédit. Ces capitaux supplémentaires – le volant contracyclique – peuvent ensuite soutenir la croissance du crédit lorsque la conjoncture économique est difficile.

Il n’est pas simple de déterminer la quantité de fonds propres bancaires nécessaire pour composer avec ces variations cycliques. Cette étude propose une nouvelle façon d’estimer ces fonds en soumettant le système bancaire à des tests de résistance automatisés, qui reposent sur des données rétrospectives tirées du marché boursier. Ces tests aident à évaluer la taille des volants contracycliques qui permettraient d’absorber des chocs graves, mais plausibles. Ils peuvent être effectués rétroactivement pour estimer l’incidence de tels chocs sur le système bancaire en périodes de forte et de faible croissance du crédit. La différence met en lumière le niveau des fonds propres requis pour contrebalancer les variations cycliques des risques.

description: We report on the first computation of the strong running coupling at the physical point (physical pion mass) from the ghost-gluon vertex, computed from lattice simulations with three flavors of Domain Wall fermions. We find $α_{\overline{\rm MS}}(m_Z^2)=0.1172(11)$, in remarkably good agreement with the world-wide average. Our computational bridge to this value is the Taylor-scheme strong coupling, which has been revealed of great interest by itself because it can be directly related to the quark-gluon interaction kernel in continuum approaches to the QCD bound-state problem.

description: A superconducting transition in the temperature dependence of the ab-plane resistivity of underdoped YBa_2Cu_3O_{6+x} crystals in the range T_c<30 K has been investigated. Unlike the case of samples with the optimal level of doping, the transition width increased insignificantly with magnetic field, and in the range T_c<13 K it decreased with increasing magnetic field. The transition point T_c(B) was determined by analyzing the fluctuation conductivity. The curves of B_{c2}(T) measured in the region T/T_c>0.1 did not show a tendency to saturation and had a positive second derivative everywhere, including the immediate neighborhood of T_c. The only difference among the curves of B_{c2}(T) for different crystal states is the scales of T and B, so they can be described in terms of a universal function, which fairly closely follows Alexandrov's model of boson superconductivity.

 Eschweilera praeclara Sandwith, Bull. Misc. Inform. Kew 1935 (3): 127 [20 May 1935] (Sandwith 1935).
 NOTES. — Known only from the Guiana Shield. Mori & Prance (Mori et al. 1990: 313) hesitantly placed Eschweilera praeclara in synonymy under L. holcogyne, specifying that it has “flowers and fruits intermediate in size between L. holcogyne and L. chartacea ”. They further hypothesized that E. praeclara could be a hybrid between these two Lecythis species. Since then, Scott Mori has become convinced that it was indeed a distinct species, whether or not it was the result of hybridization, as proven by the determinavits “ L. praeclara (Sandwith) Mori ” that he affixed to several specimens, notably at CAY. More recently, he has personally and repeatedly reasserted this position to the first two authors of the present work, at the same time explaining his reluctance to publish this new combination because of the uncertainty of the generic limits of Lecythis, which has been shown by genetic studies to be polyphyletic (Mori et al. 2017). Even so, these studies have provided evidence that E. praeclara, as well as E. congestiflora and E. simiorum are distant from the core Eschweilera, and grouped together with several Lecythis species (including L. holcogyne) in a “Chartacea clade” (Mori et al. 2017). Furthermore, L. praeclara appeared distinct from L. holcogyne (Mori et al. 2017). We are therefore in the presence of a taxon whose valid name is still E. praeclara although it does not belong to this genus. Even if it is on a provisional basis (the provisional often lasts decades when it comes to botanical nomenclature), it seems to us necessary to remove this taxon from the genus Eschweilera, and this can only be done, for the time being, by a transfer into Lecythis.

description: We present a novel database of real-time data and forecasts from the Bank of Canada’s staff economic projections. We then provide a forecast evaluation for GDP growth and CPI inflation since 1982: we compare the staff forecasts with those from commonly used time-series models estimated with real-time data and with forecasts from other professional forecasters and provide standard bias tests. Finally, we study changes in the predictability of the Canadian economy following the announcement of the inflation-targeting regime in 1991. Our database is unprecedented outside the United States, and our evidence is particularly interesting, as it includes over 30 years of staff forecasts, two severe recessions and different monetary policy regimes. The database will be made available publicly and updated annually.

Nous évaluons ensuite les prévisions relatives à la croissance du PIB et à l’inflation mesurée par l’indice des prix à la consommation depuis 1982. Pour ce faire, nous comparons les prévisions du personnel aux prévisions de modèles économétriques courants estimés à partir de données en temps réel ainsi qu’aux prévisions d’autres professionnels en la matière. Nous effectuons ensuite des tests pour vérifier la présence de biais. Enfin, nous étudions la variation de la prévisibilité de l’économie canadienne après l’annonce du régime de ciblage de l’inflation en 1991. Notre base de données est la première de cette ampleur à l’extérieur des États-Unis, et nos résultats sont particulièrement intéressants, car ils couvrent plus de 30 années de prévisions du personnel, deux récessions majeures et différents régimes de politique monétaire. La base de données, accessible au public, sera mise à jour annuellement.

description: Pressure and temperature dependent susceptibility and Raman scattering experiments on single crystalline Cu_xZn_(1-x)GeO_3 have shown an unusually strong increase of the spin-Peierls phase transition temperature upon applying hydrostatic pressure. The large positive pressure coefficient (7.5 K/GPa) - almost twice as large as for the pure compound (4.5 K/GPa) - is interpreted as arising due to an increasing magnetic frustration which decreases the spin-spin correlation length, and thereby weakens the influence of the non-magnetic Zn-substitution.

description: Gas clumps formed within massive gravitationally unstable circumstellar discs are potential seeds of gas giant planets, brown dwarfs and companion stars. Simulations show that competition between three processes -- migration, gas accretion and tidal disruption -- establishes what grows from a given seed. Here we investigate the robustness of numerical modelling of clump migration and accretion with the codes PHANTOM, GADGET, SPHINX, SEREN, GIZMO-MFM, SPHNG and FARGO. The test problem comprises a clump embedded in a massive disc at an initial separation of 120 AU. There is a general qualitative agreement between the codes, but the quantitative agreement in the planet migration rate ranges from $\sim 10$% to $\sim 50$%, depending on the numerical setup. We find that the artificial viscosity treatment and the sink particle prescription may account for much of the differences between the codes. In order to understand the wider implications of our work, we also attempt to reproduce the planet evolution tracks from our hydrodynamical simulations with prescriptions from three previous population synthesis studies. We find that the disagreement amongst the population synthesis models is far greater than that between our hydrodynamical simulations. The results of our code comparison project are therefore encouraging in that uncertainties in the given problem are probably dominated by the physics not yet included in the codes rather than by how hydrodynamics is modelled in them.

description: Chiral twisting of the molecular orientation within the layer of a smectic-A liquid crystal has been investigated using circular dichroism spectroscopy. The results indicate that a rotation of the layers away from the alignment direction is induced by the surface electroclinic effect. This leads to an interfacial region where the molecular director twists from the alignment direction until it reaches the layer normal direction. A theory is presented to explain the observed field and temperature dependence of the circular dichroism.

description: This paper studies the relationship between bank holding company affiliation and the individual and systemic risk of banks. Using the 2005 hurricane season in the US as an exogenous shock to bank balance sheets, we show that banks that are part of a holding parent company are more resilient than independent banks. Examining the impact of the liquidity of the holding on resiliency shows that banks are more fragile when the liquidity of the holding is lower, consistent with internal capital markets playing a role in stabilizing banks. We also show that banks whose holdings display low liquidity levels rebalance their portfolios towards riskier activities, such as non-traditional banking activities.
description: L’étude porte sur la relation entre l’affiliation d’une banque à une société de portefeuille bancaire et le risque particulier et systémique des banques. En prenant la saison des ouragans de 2005 qu’ont connue les États-Unis comme exemple de choc exogène pour les bilans bancaires, nous montrons que les banques contrôlées par une société de portefeuille sont plus résilientes que les banques indépendantes. Pour ce qui est de l’effet de la liquidité d’une société de portefeuille sur la résilience de ses filiales, les banques apparaissent plus fragiles quand la société mère a peu de liquidités. Cette observation est conforme aux observations trouvées dans la littérature sur le rôle joué par le financement interne dans la stabilisation des banques d’un groupe. Nous montrons aussi que les banques aux societés moins liquides réorientent leur portefeuille vers des activités plus risquées, notamment vers les activités bancaires non traditionnelles.

description: We document a strong asymmetry in the evolution of federal funds rate expectations and map this observed asymmetry into measures of monetary policy uncertainty. We show that periods of monetary policy tightening and easing are distinctly related to downside (policy rate is higher than expected) and upside (policy rate is lower than expected) uncertainty. Downside monetary policy uncertainty decreases over time, while upside uncertainty remains rather stable, reflecting the asymmetry in the behavior of the expectational errors—a finding that we attribute to changes in the conduct of monetary policy. We show that this behavior cannot be entirely explained by uncertainty in macroeconomic fundamentals: the asymmetry remains even when we control for macroeconomic uncertainty, emphasizing the importance of monetary policy implementation. Finally, we assess the macroeconomic effects of monetary policy uncertainty. We find that the effects are non-linear and conditional on the economy being in an easing or tightening regime. Though uncertainty is, in general, recessionary, its effects are stronger in a monetary easing regime relative to a tightening one.
description: Dans cette étude, nous rendons compte d’une forte asymétrie dans l’évolution des attentes à l’égard du taux des fonds fédéraux, asymétrie que nous faisons correspondre à des mesures de l’incertitude concernant la politique monétaire. Nous montrons que les périodes de resserrement monétaire sont liées à une incertitude « négative » (taux directeur supérieur aux attentes) et celles d’assouplissement monétaire, à une incertitude « positive » (taux directeur inférieur aux attentes). L’incertitude négative concernant la politique monétaire diminue au fil du temps, tandis que l’incertitude positive reste plutôt stable. Cette constatation reflète le comportement asymétrique des erreurs de prévision, que nous attribuons aux modifications de la conduite de la politique monétaire. Nous montrons que l’incertitude liée aux fondamentaux macroéconomiques ne permet pas à elle seule d’expliquer ce comportement : l’asymétrie demeure, même lorsque nous tenons compte de l’incertitude macroéconomique, ce qui fait ressortir l’importance de la mise en oeuvre de la politique monétaire. Enfin, nous évaluons les effets macroéconomiques de l’incertitude entourant la politique monétaire. Selon nos résultats, les effets, non linéaires, dépendent de la phase de détente ou de resserrement de la politique monétaire. Même si, en général, l’incertitude a des effets récessifs, ces derniers sont plus sensibles en période d’assouplissement qu’en période de resserrement monétaire.
title: Financial Development Beyond the Formal Financial Market

Publisher: name: Bank of Canada
Year: 2018

description: This paper studies the effects of financial development, taking into account both formal and informal financing. Using cross-country firm-level data, we document that informal financing is utilized more by rich countries than poor countries. To account for this empirical pattern, we build a model in which the supply of informal financing increases with financial development, while the demand for informal financing declines with it. The model generates a hump-shaped relationship between the incidence of informal financing and GDP per capita. Our analysis shows that, at the early stage of economic development, the output loss from financial frictions is reinforced by the low supply of informal financing. Informal financing contributes more to the aggregate output of the richest countries than to that of the poorer countries in our sample.
description: Nous étudions les incidences du développement des marchés financiers en prenant en considération les modes de financement aussi bien formel qu’informel. En nous fondant sur des données internationales sur les entreprises, nous constatons que le financement informel est plus courant dans les pays riches que dans les pays pauvres. Pour rendre compte de ce profil empirique, nous construisons un modèle dans lequel l’offre de financement informel s’accroît en phase avec le développement du secteur financier tandis que la demande diminue. Le modèle génère une courbe en forme de cloche représentant la relation entre l’incidence du financement informel et le PIB par habitant. Notre analyse révèle qu’aux premiers stades de développement économique, la perte de production liée aux frictions financières est exacerbée par la faiblesse de l’offre de financement informel. L’apport au PIB du financement informel est plus important pour les pays les plus riches de notre échantillon que pour les plus pauvres.

description: We present a microscopic model for nanoparticles, of the maghemite ($γ$% -Fe$_{2}$O$_{3}$) type, and perform classical Monte Carlo simulations of their magnetic properties. On account of Mössbauer spectroscopy and high-field magnetisation results, we consider a particle as composed of a core and a surface shell of constant thickness. The magnetic state in the particle is described by the anisotropic classical Dirac-Heisenberg model including exchange and dipolar interactions and bulk and surface anisotropy. We consider the case of ellipsoidal (or spherical) particles with free boundaries at the surface. Using a surface shell of constant thickness ($\sim 0.35$ nm) we vary the particle size and study the effect of surface magnetic disorder on the thermal and spatial behaviors of the net magnetisation of the particle. We study the shift in the surface ``critical region'' for different surface-to-core ratios of the exchange coupling constants. It is also shown that the profile of the local magnetisation exhibits strong temperature dependence, and that surface anisotropy is reponsible for the non saturation of the magnetisation at low temperatures.

description: Within the conventional framework of standard linear response theory we have derived exact results for the initial static susceptibilities of nonuniform spin-1/2 Ising chains. The results obtained permit one to study regularly alternating-bond and random-bond Ising chains. The influence of several types of nonuniformity and disorder on the temperature dependence of the initial longitudinal and transverse static susceptibilities is discussed.

description: Experimental results on magnetic resonance (ESR) and magnetic susceptibility are given for single crystalline (VO)$_2$P$_2$O$_{7}$. The crystal growth procedure is briefly discussed. The susceptibility is interpreted numerically using a model with alternating spin chains. We determine $J$=51 K and $δ$=0.2. Furthermore we find a spin gap of $\approx 6$meV from our ESR measurements. Using elastic constants no indication of a phase transition forcing the dimerization is seen below 300 K.

description: We present a simple model of the risk sensitivity of bank capital regulation. A banker funds a project with uninsured deposits and costly capital, where capital resolves a moral hazard problem in the choice of the probability of default. Investors are uninformed about the project’s high or low loss given default, but a regulator receives a noisy signal and imposes minimum capital requirements. We show that the sensitivity of capital regulation to measured risk is non-monotonic. For an inaccurate signal, the regulator pools banker types via risk-insensitive capital requirements. For an accurate signal, the regulator separates types via risk-sensitive capital requirements. For an even more accurate signal, the risk sensitivity of bank capital requirements falls.
description: Nous exposons, à l’aide d’un modèle simple, la sensibilité au risque de la réglementation des fonds propres bancaires. Un banquier finance un projet avec des dépôts non assurés et des fonds propres coûteux à mobiliser, les fonds propres réglant un problème d’aléa moral dans le choix de la probabilité de défaillance. Les investisseurs ne sont pas informés sur la perte élevée ou faible en cas de défaillance associée au projet, mais l’organe de réglementation reçoit un signal bruyant et impose des exigences minimales de fonds propres. Nous montrons que la sensibilité de la réglementation des fonds propres au risque mesuré n’est pas monotone. Dans le cas d’un signal imprécis, l’organe de réglementation regroupe les différents types de banquiers en imposant des exigences de fonds propres insensibles au risque. À l’inverse, lorsque le signal est précis, l’organe de réglementation distingue les différents types en appliquant des exigences de fonds propres sensibles au risque. Enfin, si le signal est encore plus précis, la sensibilité au risque des exigences de fonds propres chute.

Convective dissolution of carbon dioxide in deep saline aquifers: Insights from engineering a high-pressure porous Hele-Shaw cell

description: We present the first experiments of dissolution-driven convection of carbon dioxide (CO$_2$) in a confined brine-saturated porous medium at high pressures. We designed a novel Hele-Shaw cell that allows for both visual and quantitative analyses, and address the effects of free-phase CO$_2$ and brine composition on convective dissolution. The visual examination of the gas volume combined with the measurement of pressure, which both evolve with dissolution, enable us to yield insights into the dynamics of convection in conditions that more closely reflect the geologic conditions. We find and analyze different dissolution events, including diffusive, early and late convection, and shut-down regimes. Our experiments reveal that in intermediate regime, a so-called `quasi-steady' state actually never happens. Dissolution flux continuously decreases in this regime, which is due to a negative feedback loop: the rapid reduction of pressure following convective dissolution, in turn, decreases the solubility of CO$_2$ at the gas-brine interface and thus the instability strength. We introduce a new scaling factor that not only compensates the flux reduction but also the nonlinearities that arise from different salt types. We present robust scaling relations for the compensated flux and for the transition times between consecutive regimes in systems with NaCl (Ra $\sim$ 3271--4841) and NaCl+CaCl$_2$ mixtures (Ra $\sim$ 2919--4283). We also find that NaCl+CaCl$_2$ mixtures enjoy a longer intermediate period before the shut-down of dissolution, but with a lower dissolution flux, as compared to NaCl brines...

description: We investigate the zero-temperature BCS to Bose-Einstein crossover at the mean-field level, by driving it with the attractive potential and the particle density.We emphasize specifically the role played by the particle density in this crossover.Three different interparticle potentials are considered for the continuum model in three spatial dimensions, while both s- and d-wave solutions are analyzed for the attractive (extended) Hubbard model on a two-dimensional square lattice. For this model the peculiar behavior of the crossover for the d-wave solution is discussed.In particular, in the strong-coupling limit when approaching half filling we evidence the occurrence of strong correlations among antiparallel-spin fermions belonging to different composite bosons, which give rise to a quasi-long-range antiferromagnetic order in this limit.

title: Challenges in Implementing Worst-Case Analysis

description: Worst-case analysis is used among financial regulators in the wake of the recent financial crisis to gauge the tail risk. We provide insight into worst-case analysis and provide guidance on how to estimate it. We derive the bias for the non-parametric heavy-tailed order statistics and contrast it with the semi-parametric extreme value theory (EVT) approach. We find that if the return distribution has a heavy tail, the non-parametric worst-case analysis, i.e. the minimum of the sample, is always downwards biased and hence is overly conservative. Relying on semi-parametric EVT reduces the bias considerably in the case of relatively heavy tails. But for the less-heavy tails this relationship is reversed. Estimates for a large sample of US stock returns indicate that this pattern in the bias is indeed present in financial data. With respect to risk management, this induces an overly conservative capital allocation if the worst case is estimated incorrectly.
description: Depuis la récente crise financière, l’analyse du pire scénario est utilisée par les autorités de réglementation du secteur financier pour évaluer le risque extrême. Nous apportons de nouvelles perspectives sur cette méthode et sur l’estimation de la valeur extrême qui en découle. Nous calculons le biais des estimateurs d’ordre non paramétrique de la queue de distribution et le comparons au biais associé à la méthode semi-paramétrique de la théorie des valeurs extrêmes (TVE). Quand la distribution des rendements a une queue épaisse, nous trouvons que la valeur minimum de l’échantillon — c’est-à-dire l’estimateur issu de l’analyse du pire scénario – est très modérée dans la mesure où elle surestime toujours le risque. Dans le cas des distributions à queues relativement épaisses, le biais se réduit substantiellement grâce à l’estimateur semi-paramétrique résultant de la TVE. Pour les queues moins épaisses, la relation s’inverse. Les estimations tirées d’un large échantillon du rendement d’actions du marché américain révèlent en effet la présence d’un comportement semblable dans les données financières. Sur le plan de la gestion du risque, ce résultat se traduit par une allocation très prudente des capitaux si le pire scénario est incorrectement estimé.

description: We analyze the magnetic field geometry and the transport processes of the cosmic rays of the edge-on spiral starburst galaxy NGC 4666 from CHANG-ES radio continuum data in two frequencies; 6 GHz (C-band) and 1.5 GHz (L-band). Supplementary X-ray data are used to investigate the hot gas in NGC 4666. We determine the radio scale heights of total power emission at both frequencies for this galaxy. We show the magnetic field orientations derived from the polarization data. Using rotation measure (RM) synthesis we further study the behavior of the RM values along the disk in C-band to investigate the large-scale magnetic-field pattern. We use the revised equipartition formula to calculate a map of the magnetic field strength. Furthermore, we model the processes of cosmic-ray transport into the halo with the 1D SPINNAKER model. The extended radio halo of NGC 4666 is box-shaped and is probably produced by the previously observed supernova-driven superwind. This is supported by our finding of an advective cosmic-ray transport such as that expected for a galactic wind. The scaleheight analysis revealed an asymmetric halo above and below the disk as well as between the two sides of the major axis. A central point source as well as a bubble structure is seen in the radio data for the first time. Our X-ray data show a box-shaped hot halo around NGC 4666 and furthermore confirm the AGN nature of the central source. NGC 4666 has a large-scale X-shaped magnetic field in the halo, as has been observed in other edge-on galaxies. The analysis furthermore revealed that the disk of NGC 4666 shows hints of field reversals along its radius, which is the first detection of this phenomenon in an external galaxy.
