Whether TDGs can live that long is still poorly constrained by observations. As part of deep optical and H I surveys with the CFHT MegaCam camera and Westerbork Syn- thesis Radio Telescope made within the ATLAS3D project, and follow-up spectroscopic ob- servations with the Gemini-North telescope, we have discovered old TDG candidates around several early-type galaxies.

Also, Saturn is looking quite striking as the rings are now tilted at a nice angle allowing us to see the Casini Division and shadows on and from the planet. Don't miss it! I've been asked by BREC to make sure our club members are all aware of the Park Rules listed on BREC's website. Many of the rules are actually ordinances enacted by the city of Baton Rouge (e.g., No smoking permitted in public areas, No alcohol brought onto or sold on BREC property, No Gambling, No Firearms or Weapons, etc.) Please make sure you observe all of the Park Rules while at the HRPO and provide good examples for the general public. (Many of which are from outside East Baton Rouge Parish and are likely unaware of some of the policies.) For a full list of BREC's Park Rules, you may visit their Park Rules section of their website at http://brec.org/index.cfm/page/555/n/75 I'm sorry I had to miss the outing to LIGO, but it will be good to see some folks again at our meeting on Monday, June 10th.

  • Espiritualidad, Chakras Y Catedrales Góticas
    Espiritualidad, Chakras y Catedrales Góticas Las catedrales son símbolo del poder religioso. En Francia, las catedrales góticas de Chartres, Paris, Reims, Amiens, Evreux, Bayeaux, están cargadas de un alto simbolismo. Si en un plano unimos las citadas catedrales nos encontramos que forman, en plano-tierra, la Constelación de Virgo (Virginis), esto mismo lo encontramos en las pirámides de Gizeh, que forman el cinturón de la Constelación del Orión; siguiendo la ley metafísica “Cómo es arriba es abajo”. La catedral de Reims representa a la estrella Alfa Virginis, la estrella más brillante de la constelación de Virgo, de magnitud 1,2. Curiosamente Reims fue erigida a partir de 1211. Es la catedral donde se coronaban los reyes de Francia. Tardaron dos siglos y medio en concluirla y el resultado fue una construcción bellísima de 138 metros de largo y más de 2300 esculturas (530 solo en los tres pisos de la fachada principal). Todas estas catedrales góticas dedicadas a Notre Dame (Nuestra Señora), es decir, a la Virgen (Virgo) son construidas por los masones, agrupados en logias (masonería), y mientras los constructores románicos construyen románico, los góticos construyen gótico, por lo que son don estilos que coexisten en el tiempo. Algunos estudiosos apuntan que mientras el románico necesitó de pruebas antes de ser levantado cualquier edificio, el gótico no necesitó de pruebas, es decir, los masones sabían muy bien que sus mediciones eran correctas y levantaban los edificios directamente, sin prueba alguna. Los conocimientos de estos constructores góticos fueron traídos por los templarios venidos de Tierra Santa, que convivieron con sabios árabes (sufíes) y con sabios judíos (cabalistas).

  • MASSIVE Galaxies with Supermassive Black Holes
    Hubble Space Telescope Cycle 23 GO Proposal 750 Homogeneous Distances and Central Profiles for MASSIVE Survey Galaxies with Supermassive Black Holes Scientific Category: UNRESOLVED STELLAR POPULATIONS AND GALAXY STRUCTURE Scientific Keywords: Black Holes, Cosmological Parameters And Distance Scale, Galaxy Centers, Galaxy Morphology And Structure Instruments: WFC3 Proprietary Period: 12 Proposal Size: Small Orbit Request Prime Parallel Cycle 23 34 0 Abstract Massive early-type galaxies are the subject of intense interest: they exhibit the most massive black holes (BHs), most extreme stellar IMFs, and most dramatic size evolution over cosmic time. Yet, their complex formation histories remain obscure. Enter MASSIVE: a volume-limited survey of the structure and dynamics of the 100 most massive early-type galaxies within ~100 Mpc. We use integral-field spectroscopy (IFS) on sub-arcsecond (with AO) and large scales for simultaneous dynamical modeling of the supermassive BH, stars, and dark matter. The goals of MASSIVE include precise constraints on BH-galaxy scaling relations, the stellar IMF, and late-time assembly of ellipticals. We have already obtained much of the needed IFS and wide-field imaging for this project; here, we propose to add the one missing ingredient: high-resolution imaging with HST. This will nail down the central profiles, greatly reducing the degeneracy between M/L and BH masses in our dynamical orbit modeling. Further, we will measure efficient, high-quality WFC3/IR SBF distances for all targets, thereby removing potentially large errors from peculiar velocities (especially in the high-density regions occupied by massive early-types) or heterogeneous distance methods. Distance errors are insidious: they affect BH masses and galaxy properties in dissimilar ways, and thus can bias both the scatter and slopes of the scaling relations.

We quantify the degree of lopsidedness for a sample of 149 galaxies observed in the near-infrared from the OSUBGS sample, and try to explain the physical origin of the observed disk lopsidedness. We confirm previous studies, but for a larger sample, that a large fraction of galaxies have significant lopsidedness in their stellar disks, measured as the Fourier amplitude of the m = 1 component normalised to the average or m = 0 component in the surface density. Late-type galaxies are found to be more lopsided, while the presence of m = 2 spiral arms and bars is correlated with disk lopsidedness. We also show that the m = 1 amplitude is uncorrelated with the presence of companions. Numerical simulations were carried out to study the generation of m = 1viadifferent processes: galaxy tidal encounters, galaxy mergers, and external gas accretion with subsequent star formation. These simulations show that galaxy interactions and mergers can trigger strong lopsidedness, but do not explain several independent statistical properties of observed galaxies. To explain all the observational results, it is required that a large fraction of lopsidedness results from cosmological accretion of gas on galactic disks, which can create strongly lopsided disks when this accretion is asymmetrical enough.
