We examine the validity of this reconstruction\nalgorithm by performing an observational test of it with the Virgo cluster as a\ntarget. We first modify the LK06 algorithm by incorporating the two dimensional\nprojection effect.

Since the spins of fermions are normally randomly\noriented in macroscopic bodies, the torsion generated is normally negligible.\nHowever, in a recent paper, Mao et al. point out that there is a class of\ntheories in which the angular momentum of macroscopic spinning bodies generates\na significant amount of torsion. They argue that by the principle of action\nequals reaction, one would expect the angular momentum of test bodies to couple\nto a background torsion field, and therefore the precession of the GPB\ngyroscopes should be affected in these theories by the torsion generated by the\nEarth. We show that in fact the principle of action equals reaction does not\napply to these theories. We examine in detail a generalization of the\nHayashi-Shirafuji theory suggested by Mao et al. called\nEinstein-Hayashi-Shirafuji theory. There are a variety of different versions of\nthis theory, depending on the precise form of the coupling to matter chosen for\nthe torsion. We show that for any coupling to matter that is compatible with\nthe spin transport equation postulated by Mao et al., the theory has either\nghosts or an ill-posed initial value formulation. These theoretical problems\ncan be avoided by specializing the parameters of the theory and in addition\nchoosing the standard minimal coupling to matter of the torsion tensor. This\nyields a consistent theory, but one in which the action equals reaction\nprinciple is violated, and in which the angular momentum of the gyroscopes does\nnot couple to the Earth\'s torsion field.

The 8 micron images\nindicate that polycyclic aromatic hydrocarbon molecules are present in the\ncentral regions of all three metal-poor LSB galaxies. The diffuse optical disks\nof Malin 1 and UGC 9024 remain undetected at mid- and far-infrared wavelengths.\nThe dustiest of the three LSB galaxies, UGC 6614, has infrared morphology that\nvaries significantly with wavelength. The 8 and 24 micron emission is\nco-spatial with H\\alpha emission previously observed in the outer ring of UGC\n6614. The estimated dust-to-gas ratios, from less than 10^{-3} to 10^{-2},\nsupport previous indications that the LSB galaxies are relatively dust poor\ncompared to the HSB galaxies. The total infrared luminosities are approximately\n1/3 to 1/2 the blue band luminosities, suggesting that old stellar populations\nare the primary source of dust heating in these LSB objects.

No evidence is found\nfor any loss of angular momentum during the main-sequence life. The magnetic\nflux remains constant over the stellar life time on the main sequence. An\nexcess of stars with large obliquities beta is detected in both higher and\nlower mass stars. The obliquity angle distribution as inferred from the\ndistribution of r-values appears random at the time magnetic stars become\nobservable on the H-R diagram. After quite a short time spent on the main\nsequence, the obliquity angle beta tends to reach values close to either 90 deg\nor 0 deg for M < 3 M_sun. The evolution of the obliquity angle beta seems to be\nsomewhat different for low and high mass stars. While we find a strong hint for\nan increase of beta with the elapsed time on the main sequence for stars with M\n> 3 M_sun, no similar trend is found for stars with M < 3 M_sun. However, the\npredominance of high values of beta at advanced ages in these stars is notable.\n', '[{\"version\":\"v1\",\"created\":\"Wed, 11 Apr 2007 22:54:23 GMT\"}]', '2015-05-13', '[[\"Hubrig\",\"S.\",\"\"],[\"North\",\"P.\",\"\"],[\"Schoeller\",\"M.\",\"\"]]'),

We illustrate the importance of the two-armed spiral\nmode in the generation of superhumps. Differential motions in the fluid disc\ncause converging flows which lead to strong spiral shocks once each superhump\ncycle. The dissipation associated with these shocks powers the superhump. We\ncompare 2D and 3D results, and conclude that 3D simulations are necessary to\nfaithfully simulate the disc dynamics. We ran our simulations for unprecedented\ndurations, so that an eccentric equilibrium is established except at high mass\nratios where the growth rate of the instability is very low. Our improved\nsimulations give a closer match to the observed relationship between superhump\nperiod excess and binary mass ratio than previous numerical work. The observed\nblack hole X-ray transient superhumpers appear to have systematically lower\ndisc precession rates than the cataclysmic variables. This could be due to\nhigher disc temperatures and thicknesses. The modulation in total viscous\ndissipation on the superhump period is overwhelmingly from the region of the\ndisc within the 3:1 resonance radius. As the eccentric instability develops,\nthe viscous torques are enhanced, and the disc consequently adjusts to a new\nequilibrium state, as suggested in the thermal-tidal instability model. We\nquantify this enhancement in the viscosity, which is ~10 per cent for q=0.08.\nWe characterise the eccentricity distributions in our accretion discs, and show\nthat the entire body of the disc partakes in the eccentricity.\n', '[{\"version\":\"v1\",\"created\":\"Thu, 12 Apr 2007 02:57:28 GMT\"}]', '2008-12-18', '[[\"Smith\",\"Amanda J.\",\"\"],[\"Haswell\",\"Carole A.\",\"\"],[\"Murray\",\"James R.\",\"\"],[\"Truss\",\"Michael R.\",\"\"],[\"Foulkes\",\"Stephen B.\",\"\"]]'),

One of the typical features shown by observations of solar\nprominence oscillations is that they are damped in time and that the values of\nthe damping times are usually between one and three times the corresponding\noscillatory period. However, the mechanism responsible for the attenuation is\nstill not well-known. Aims. Thermal conduction, optically thin or thick\nradiation and heating are taken into account in the energy equation, and their\nrole on the attenuation of prominence oscillations is evaluated. Methods. The\ndispersion relation for linear non-adiabatic magnetoacoustic waves is derived\nconsidering an equilibrium made of a prominence plasma slab embedded in an\nunbounded corona. The magnetic field is orientated along the direction parallel\nto the slab axis and has the same strength in all regions. By solving the\ndispersion relation for a fixed wavenumber, a complex oscillatory frequency is\nobtained, and the period and the damping time are computed. Results. The effect\nof conduction and radiation losses is different for each magnetoacoustic mode\nand depends on the wavenumber. In the observed range of wavelengths the\ninternal slow mode is attenuated by radiation from the prominence plasma, the\nfast mode by the combination of prominence radiation and coronal conduction and\nthe external slow mode by coronal conduction. The consideration of the external\ncorona is of paramount importance in the case of the fast and external slow\nmodes, whereas it does not affect the internal slow modes at all.

We advocate an alternative hypothesis,\nthat the Solar System\'s protoplanetary disk had already formed when a very\nclose (< 1 pc) supernova injected radioactive material directly into the disk.\nWe conduct the first numerical simulations designed to answer two questions\nrelated to this hypothesis: will the disk be destroyed by such a close\nsupernova; and will any of the ejecta be mixed into the disk? Our simulations\ndemonstrate that the disk does not absorb enough momentum from the shock to\nescape the protostar to which it is bound. Only low amounts (< 1%) of mass loss\noccur, due to stripping by Kelvin-Helmholtz instabilities across the top of the\ndisk, which also mix into the disk about 1% of the intercepted ejecta. These\nlow efficiencies of destruction and injectation are due to the fact that the\nhigh disk pressures prevent the ejecta from penetrating far into the disk\nbefore stalling. Injection of gas-phase ejecta is too inefficient to be\nconsistent with the abundances of radionuclides inferred from meteorites. On\nthe other hand, the radionuclides found in meteorites would have condensed into\ndust grains in the supernova ejecta, and we argue that such grains will be\ninjected directly into the disk with nearly 100% efficiency.

It is pointed out that a gravitationally collapsing black hole acts as\nan ultrahigh energy particle accelerator that can accelerate particles to\nenergies inconceivable in any terrestrial particle accelerator, and that when\nthe energy $E$ of the particles comprising matter in a black hole is $\\sim\n10^{2} GeV$ or more, or equivalently, the temperature $T$ is $\\sim 10^{15} K$\nor more, the entire matter in the black hole is converted into quark-gluon\nplasma permeated by leptons. As quarks and leptons are fermions, it is\nemphasized that the collapse of a black-hole to a space-time singularity is\ninhibited by Pauli\'s exclusion principle. It is also suggested that ultimately\na black hole may end up either as a stable quark star, or as a pulsating quark\nstar which may be a source of gravitational radiation, or it may simply explode\nwith a mini bang of a sort.\n', '[{\"version\":\"v1\",\"created\":\"Thu, 12 Apr 2007 20:22:20 GMT\"},{\"version\":\"v2\",\"created\":\"Tue, 24 Jun 2008 19:03:24 GMT\"}]', '2008-06-24', '[[\"Thakur\",\"R.

Deep, wide-field observations for this\nproject were made in two bands at the one meter Swope and 2.5 meter du Pont\ntelescope at Las Campanas Observatory. Careful attention in reduction and\nanalysis was paid to the illumination correction, background subtraction, point\nspread function determination, and galaxy subtraction. ICL flux is detected in\nboth bands in all ten clusters ranging from 7.6 x 10^{10} to 7.0 x 10^{11}\nh^{-1} solar luminosities in r and 1.4 x 10^{10} to 1.2 x 10^{11} h^{-1} solar\nluminosities in the B-band. These fluxes account for 6 to 22% of the total\ncluster light within one quarter of the virial radius in r and 4 to 21% in the\nB-band. Average ICL B-r colors range from 1.5 to 2.8 mags when k and evolution\ncorrected to the present epoch. In several clusters we also detect ICL in group\nenvironments near the cluster center and up to ~1 h^{-1} Mpc distant from the\ncluster center. Our sample, having been selected from the Abell sample, is\nincomplete in that it does not include high redshift clusters with low density,\nlow flux, or low mass, and it does not include low redshift clusters with high\nflux, mass, or density. This bias makes it difficult to interpret correlations\nbetween ICL flux and cluster properties. Despite this selection bias, we do\nfind that the presence of a cD galaxy corresponds to both centrally\nconcentrated galaxy profiles and centrally concentrated ICL profiles. This is\nconsistent with ICL either forming from galaxy interactions at the center, or\nforming at earlier times in groups and later combining in the center.\n', '[{\"version\":\"v1\",\"created\":\"Thu, 12 Apr 2007 20:50:41 GMT\"}]', '2009-06-23', '[[\"Krick\",\"J.
