... The formation of the disks of disk galaxies remains poorly understood. ... Many disk galaxies have only the thin disk component, with no bulge or significant thick disk. ... Almost all disk galaxies have an exponential radial surface brightness distribution. The reason for this exponential form is not known; nor is it known when the exponential form is established. ... We would compare low redshift galaxies observed in the I band with galaxies at z =0.5 in the J band and at z =1 in the H band. ...

Dwarf novae are a subclass of cataclysmic variable stars in which a late-type secondary fills its Roche lobe and transfers mass to a white dwarf primary via an accretion disc. ... Those spiral structures are very similar to the spiral shocks discovered by Sawada, Matsuda & Hachisu (1986) in 2D finite difference numerical simulations in accretion discs. In this poster, we want to compare 2D numerical simulations of accretion disc with the observations of SH2 . ...

The big radio lobes (=cocoon) produced by jets often contain optical emission (narrow lines and continuum) aligned with the radio jets. The implication is jet induced star formation and the coexistance of quite normal gas (100/ccm, 10,000 K) coexists with the exotic jet plasma (1/100,000 /ccm, trio. ...

... An alternate model dominated by smaller grains, near the blowout size a~0.5 ЮМm, located at 30-40 AU is also possible but requires the dust to have been produced recently, since such small grains will be expelled from the system by radiation pressure in approximately a few times 102 yr. ...

Next: Radiopulsars as Sources of Up: Cosmic Rays and Evolution Previous: Cosmic Rays and Evolution . Presently, there is little doubt that galactic CR can be generated at rapidly expanding shock fronts produced by supernova explosions. ... Statistical properties of radiopulsars in our Galaxy indicate a formation rate of NS of about 1 per 10-20 years in the present cosmological epoch, while direct astronomical observations have so far not detected supernova explosions at this high rate. ...

The FastSound projectтАЩs 3-D map of the large-scale structure of a region in the universe about 4.7 billion years after the Big Bang. This area covers 2.5 times 3 degrees of the sky, with a radial distance spanning 12-14.5 billion light-years in comoving distance or 8-9.6 billion light-years in light travel distance. The colors of the galaxies indicate their star formation rate, i.e., the total mass of stars produced in a galaxy every year. ... NAOJ, SDSS, CFHT ...

Most current theories for magnetospheric emission can be grouped into polar cap, outer gap, and nebular models. These models, at least in some cases, need not be mutually exclusive; the Crab pulsar (among others), for example, shows clear evidence for pulsed emission from the magnetosphere and unpulsed emission from the surrounding nebula. ... This suggestion is strengthened by observation of a distinct soft emission component, consistent with the cooling scenario, from several of these pulsars. ...

... Future seminars . ... The flows and pools on Mars" . L.V. Ksanfomaliti (IKI) . ... Proofs appear that the nature of extended dark formation on crater’s slopes and hills of Mars is connected with now existing sources of fluid water, disposed on declivities, and produced by its flows, rather then with moving the greater masses of dry sand (dust) or with rolling stones. ... Presence of greater spares of permafrost on Mars and conditions for its local melting to fluid phase is well known. ...
