SMSS J0313-6708, la stella più povera di ferro mai individuata: un fossile, anche se non si tratta di una stella di primissima generazione (non ce ne sono), e che si deve essere formata da materiale già arricchito durante le grandi esplosioni di supernova avvenute durante le prime fasi dell’Universo.

description: I review progress made in understanding the nature of the broad-line region (BLR) of active galactic nuclei (AGNs) and the role BLRs play in the AGN phenomenon. The high equivalent widths of the lines imply a high BLR covering factor, and the absence of clear evidence for absorption by the BLR means that the BLR has a flattened distribution and that we always view it near pole-on. The BLR gas is strongly self-shielding near the equatorial plane. Velocity-resolved reverberation mapping has long strongly excluded significant outflow of the BLR and shows instead that the predominant motions are Keplerian with large turbulence and a significant net inflow. The rotation and turbulence are consistent with the inferred geometry. The blueshifting of high-ionization lines is a consequence of scattering off inflowing material rather than the result of an outflowing wind. The rate of inflow of the BLR is sufficient to provide the accretion rate needed to power the AGN. Because the motions of the BLR are gravitationally dominated, and the BLR structure is very similar in most AGNs, consistent black hole masses can be determined. The good correlation between these estimates and masses predicted from the bulge luminosities of host galaxies provides strong support for the similarity of AGN continuum shapes and the correctness of the BLR picture presented. It is concluded that although many mysteries remain about the details of how AGNs work, a general overall picture of the torus and BLR is becoming clear.

description: We analyse the evolution of the properties of the low-redshift Intergalactic Medium (IGM) using high-resolution hydrodynamic simulations that include a detailed chemical evolution model. We focus on the effects that two different forms of energy feedback, strong galactic winds driven by supernova explosion and Active Galactic Nuclei (AGN) powered by gas accretion onto super-massive black holes (BHs), have on the thermo- and chemo-dynamical properties of of the low redshift IGM. We find that feedback associated to winds (W) and BHs leave distinct signatures in both the chemical and thermal history of the baryons, especially at redshift z<3 [..] We present results for the enrichment in terms of mass and metallicity distributions for the WHIM phase, both as a function of density and temperature. Finally, we compute the evolution of the relative abundances between different heavy elements, namely Oxygen, Carbon and Iron. While both C/O and O/Fe evolve differently at high redshifts for different feedback models, their values are similar at z=0 [..]. The sensitivity of WHIM properties on the implemented feedback scheme could be important both for discriminating between different feedback physics and for detecting the WHIM with future far-UV and X-ray telescopes.

description: The objective of this study was to determine if racial differences exist between older Non-Hispanic Black (NHB) and White (NHW) men in incident dementia over 11 years (2011–2022) in the National Health and Aging Trends Study (NHATS). The analytic sample included 2395 community-dwelling NHB and NHW men free of dementia at baseline who self-identified as Non-Hispanic Black (NHB) and White (NHW). Dementia was assessed at each visit using a validated algorithm developed by NHATS. After adjusting for demographics, place, and health-related characteristics in the Cox proportional hazard models, older NHB men had an increased risk of dementia (hazard ratio: 1.63, 95% confidence interval: [1.22–2.17]) compared to older NHW men. There may be unique factors such as stressors, patterns of genes, or perhaps nutrition that older NHB men possess and experience throughout their lives that contribute to the increased incident dementia.

description: Proposed cosmological surveys will make use of photometric redshifts of galaxies that are significantly fainter than any complete spectroscopic redshift surveys that exist to train the photo-z methods. We investigate the photo-z biases that result from known differences between the faint and bright populations: a rise in AGN activity toward higher redshift, and a metallicity difference between intrinsically luminous and faint early-type galaxies. We find that even very small mismatches between the mean photometric target and the training set can induce photo-z biases large enough to corrupt derived cosmological parameters significantly. A metallicity shift of ~0.003dex in an old population, or contamination of any galaxy spectrum with ~0.2% AGN flux, is sufficient to induce a 10^-3 bias in photo-z. These results highlight the danger in extrapolating the behavior of bright galaxies to a fainter population, and the desirability of a spectroscopic training set that spans all of the characteristics of the photo-z targets, i.e. extending to the 25th mag or fainter galaxies that will be used in future surveys.

The homogeneous catalytic activation of molecular hydrogen by cupric salts in aqueous solution
Creators: name: Peters, Ernest
Publisher: name: University of British Columbia
Year: 2012

description: Hydrogen, which is relatively inert at ordinary temperatures, was found to be, activated homogeneously in aqueous solution try dissolved cupric salts, as shown by their catalytic effect on the reactions between H₂ and reducible substrates such as Cr₂O₇⁼, IO₃⁻, and Ce⁺⁺⁺⁺. From kinetic studies of the Cu(ll)-catalyzed hydrogenation of Cr₂O₇⁼, it was shown that the catalytic activity of Cu⁺⁺ is greatly influenced by complex-forming reagents. The catalytic activities of cupric complexes were found to decrease in the order: butyrate, propionate > acetate > sulphate > chloride > H₂O (i.e. the uncomplexed Cu⁺⁺ ion) > glycine, ethylene-diamine . In all systems that were studied, the reaction was.found to be second order kinetically, the rate being proportional to the concentrations of Cu(ll) and H₂. The occurrence of an H⁺ ion as a product of the initial step of the reaction was postulated to account for the perchloric acid dependence of the rate. The promoting effect of various negative ions, which follows the order of their basicities, was thus explained by assigning to them the role of stabilizing the H⁺ ion. The following mechanism was postulated to account for the observed kinetics: Cu(ll) + H₂ [symbol omitted] CuH⁺ + H⁺ CuH⁺ + substrates [symbol omitted] Cu(ll) + products CuH⁺, the activated intermediate suggested by this mechanism, also seems on energetic grounds to be the most plausible of the possible intermediates having reasonable classical structures. It is suggested that the catalytic activity of Cu⁺⁺ is related to its electron affinity. An attempt is made to extend this interpretation to other homogeneous and heterogeneous hydrogenation catalysts.

description: We report on recent XMM-Newton observations, archival radio continuum and CO data, and SED modeling of the unidentified Galactic plane source HESS J1708-410. No significant extended X-ray emission is observed, and we place an upper limit of 3.2 x 10{-13} erg cm{-2} s{-1} in the 2-4 keV range for the region of TeV emission. Molonglo Galactic Plane Survey data is used to place an upper limit of 0.27 Jy at 843 MHz for the source, with a 2.4 GHz limit of 0.4 Jy from the Parkes survey of the southern Galactic plane. 12CO (J 1->0) data of this region indicates a plausible distance of 3 kpc for HESS J1708-410. SED modeling of both the H.E.S.S. detection and flux upper limits offer useful constraints on the emission mechanisms, magnetic field, injection spectrum, and ambient medium surrounding this source.

description: We present a detailed study of the star cluster population detected in the galaxy NGC922, one of the closest collisional ring galaxies known to date, using HST/WFPC2 UBVI photometry, population synthesis models, and N-body/SPH simulations.We find that 69% of the clusters are younger than 7Myr, and that most of them are located in the ring or along the bar, consistent with the strong Halpha emission. The cluster luminosity function slope of 2.1-2.3 for NGC922 is in agreement with those of young clusters in nearby galaxies. Models of the cluster age distribution match the observations best when cluster disruption is considered. We also find clusters with ages (>50Myr) and masses (>10^5 Msun) that are excellent progenitors for faint fuzzy clusters. The images also show a tidal plume pointing toward the companion. Its stellar age from our analysis is consistent with pre-existing stars that were stripped off during the passage of the companion. Finally, a comparison of the star-forming complexes observed in NGC922 with those of a distant ring galaxy from the GOODS field indicates very similar masses and sizes, suggesting similar origins.

description: We study the existence and stability of static kink-like configurations of a 5D scalar field, with Dirichlet boundary conditions, along the extra dimension of a warped braneworld. In the presence of gravity such configurations fail to stabilize the size of the extra dimension, leading us to consider additional scalar fields with the role of stabilization. We numerically identify multiple nontrivial solutions for a given 5D action, made possible by the nonlinear nature of the background equations, which we find is enhanced in the presence of gravity. Finally, we take a first step towards addressing the question of the stability of such configurations by deriving the full perturbative equations for the gravitationally coupled multi-field system.

description: We present the spectroscopic orbit solutions of three double-lines eclipsing binaries, BG Ind, IM Mon and RS Sgr. The first precise radial velocities (RVs) of the components were determined using high resolution echelle spectra obtained at Mt. John University Observatory in New Zealand. The RVs of the components of BG Ind and RS Sgr were measured using Gaussian fittings to the selected spectral lines, whereas two-dimensional cross-correlation technique was preferred to determine the RVs of IM Mon since it has relatively short orbital period among the other targets and so blending of the lines is more effective. For all systems, the Keplerian orbital solution was used during the analysis and also circular orbit was adopted because the eccentricities for all targets were found to be negligible. The first precise orbit analysis of these systems gives the mass ratios of the systems as 0.894, 0.606 and 0.325, respectively for BG Ind, IM Mon and RS Sgr. Comparison of the mass ratio values, orbital sizes and minimum masses of the components of the systems indicates that all systems should have different physical, dynamical and probable evolutionary status.

On the origin of globular cluster bimodality

description: Globular cluster systems in most large galaxies display bimodal color and metallicity distributions, which are frequently interpreted as indicating two distinct modes of cluster formation. The metal-rich (red) and metal-poor (blue) clusters have systematically different locations and kinematics in their host galaxies. However, the red and blue clusters have similar internal properties, such as the masses, sizes, and ages. It is therefore interesting to explore whether both metal-rich and metal-poor clusters could form by a common mechanism and still be consistent with the bimodal distribution. We show that if all globular clusters form only during mergers of massive gas-rich protogalactic disks, their metallicity distribution could be statistically consistent with that of the Galactic globulars. We take galaxy assembly history from cosmological dark matter simulations and couple it with the observed scaling relations for the amount of cold gas available for star formation. In the best-fit model, early mergers of smaller hosts create exclusively blue clusters, whereas subsequent mergers of progenitor galaxies with a range of masses create both red and blue clusters. Thus bimodality arises naturally as the result of a small number of late massive merger events. We calculate the cluster mass loss, including the effects of two-body scattering and stellar evolution, and find that more blue clusters than red clusters are disrupted by the present time, because of their smaller initial masses and larger ages. The present-day mass function in the best-fit model is consistent with the Galactic distribution. However, the spatial distribution of model clusters is much more extended than observed and is independent of the parameters of our model.

Classical simulation of quantum computation, the Gottesman-Knill theorem, and slightly beyond
Creators: name: Nest, M. Van den
Publisher: name: arXiv
Year: 2008
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We study classical simulation of quantum computation, taking the Gottesman-Knill theorem as a starting point. We show how each Clifford circuit can be reduced to an equivalent, manifestly simulatable circuit (normal form). This provides a simple proof of the Gottesman-Knill theorem without resorting to stabilizer techniques. The normal form highlights why Clifford circuits have such limited computational power in spite of their high entangling power. At the same time, the normal form shows how the classical simulation of Clifford circuits fits into the standard way of embedding classical computation into the quantum circuit model. This leads to simple extensions of Clifford circuits which are classically simulatable. These circuits can be efficiently simulated by classical sampling ('weak simulation') even though the problem of exactly computing the outcomes of measurements for these circuits ('strong simulation') is proved to be #P-complete--thus showing that there is a separation between weak and strong classical simulation of quantum computation.

description: The aim of the research was to study transport properties of two heterostructures based on AlGaN by cathodoluminescence technique. Transport processes of charge carriers was simulated. It has been shown that the diffusion of carriers in these samples exerts a significant contribution to the quantum well cathodoluminescence. It was also shown that the efficiency of diffusion of charge carriers from the upper waveguide layer is considerably worse thanthat of the lower waveguide layer.

description: A signature of the dark energy equation of state may be observed in the shape of voids. We estimate the constraints on cosmological parameters that would be determined from the ellipticity distribution of voids from future spectroscopic surveys already planned for the study of large scale structure. The constraints stem from the sensitivity of the distribution of ellipticity to the cosmological parameters through the variance of fluctuations of the density field smoothed at some length scale. This length scale can be chosen to be of the order of the comoving radii of voids at very early times when the fluctuations are Gaussian distributed. We use Fisher estimates to show that the constraints from void ellipticities are promising. Combining these constraints with other traditional methods results in the improvement of the Dark Energy Task Force Figure of Merit on the dark energy parameters by an order of hundred for future experiments. The estimates of these future constraints depend on a number of systematic issues which require further study using simulations. We outline these issues and study the impact of certain observational and theoretical systematics on the forecasted constraints on dark energy parameters.

description: PART ONE The long wave spectrum of formaldehyde vapour was observed at various temperatures. From this work it was shown that: 1. ) the α-band at 3703Å is a hot band probably arising from a lower state involving the coriolus coupled normal modes of vibration ν₅ = 1 and ν₆ = 1. 2. ) a series of bands designated as the B-bands originate from monomeric formaldehyde vapour and are probably due to a ³π ← n electronic transition. PART TWO The high resolution proton magnetic resonance spectra of hydroxyl hydrogen bonding systems and aldehydes were investigated. From this work it was shown that the forces responsible for hydrogen bonding are mainly electrostatic in nature and that the large magnitude of these forces is probably due to mutual polarization occurring in the molecular aggregates.

description: We present a case study of the 13 July 2004 solar event, in which disturbances caused by eruption of a filament from an active region embraced a quarter of the visible solar surface. Remarkable are absorption phenomena observed in the SOHO/EIT 304 A channel; they were also visible in the EIT 195 A channel, in the H-alpha line, and even in total radio flux records. Coronal and Moreton waves were also observed. Multi-spectral data allowed reconstructing an overall picture of the event. An explosive filament eruption and related impulsive flare produced a CME and blast shock, both of which decelerated and propagated independently. Coronal and Moreton waves were kinematically close and both decelerated in accordance with an expected motion of the coronal blast shock. The CME did not resemble a classical three-component structure, probably, because some part of the ejected mass fell back onto the Sun. Quantitative evaluations from different observations provide close estimates of the falling mass, ~3 10^15 g, which is close to the estimated mass of the CME. The falling material was responsible for the observed large-scale absorption phenomena, in particular, shallow widespread moving dimmings observed at 195 A. By contrast, deep quasi-stationary dimmings observed in this band near the eruption center were due to plasma density decrease in coronal structures.

description: D-Mannitol was simultaneously tritylated and acetylated to give 1,6-di-0-trityl-D-mannitol tetraacetate in 70% yield, using a procedure that gave a product completely free from triphenylcarbinol. Direct tritylation of D-mannitol yielded 1,6-di-O-trityl-D-mannitol which was crystallized, probably as a solvated molecule, from alcohol and water. Acetylation of this compound gave 1,6-di-0-trityl-D-mannitol tetraacetate in good yield. Detritylation of 1,6-di-O-trityl-D-mannitol tetraacetate to D-mannitol-2,3,4,5-tetraacetate was effected by hydrogen bromide in glacial acetic acid, catalytic hydrogenolysis over platinum oxide, and refluxing with dilute acetic acid, and the latter convenient method was found to give the highest yield of pure product. A sirupy di-O-methyl-D-mannitol was prepared from D-raannitol-2,3,4,5-tetraacetate by methylation followed by deacetylation on an ion exchange column. The structure of is this compound has not been established. A nearly colorless, amorphous solid was isolated in 2.7% yield by 50% aqueous ethanol extraction of the finely-divided wood of a Western Hemlock tree (Tsuga heterophylla) which had previously been exhaustively extracted with benzene. Treatment of this material with concentrated hydrochloric acid in methanol yielded a purple solid whose red-violet methanol solution was stable to ordinary light. The paper chromatographic behaviour and color reactions compared with a red rose petal extract and the methoxyl content indicated that the purple solid was probably an anthocyanidin containing methoxyl groups. Acetylation of the original solid extract with pyridine and acetic anhydride gave a dextrorotatory yellow sirup soluble in chloroform.
