We\nassume that a fraction of jet energy, which is generated by an AGN, is\ntransferred to the surrounding gas as thermal energy. Combining a theoretical\nmodel of mass accretion onto black holes with a multiphase description of\nstar-forming gas, we self-consistently follow evolution of both galaxies and\ntheir central black holes. The novelty in our model is that we consider two\ndistinct accretion modes: standard radiatively efficient thin accretion disks\nand radiatively inefficient accretion flows which we will generically refer to\nas RIAFs; motivated by theoretical models for jet production in accretion\ndisks, we assume that only the RIAF is responsible for the AGN feedback. We\nfind that, after an initial episode of bursting star formation, the accretion\nrate onto the central black hole drops so that the accretion disk switches to a\nRIAF structure. At this point, the feedback from the AGN becomes efficient and\nslightly suppresses star formation in the galactic disk and almost completely\nhalts star formation in the bulge. As a result, the nucleus becomes a\nstochastically fuelled low-luminosity AGN (Seyfert galaxy) with recurrent\nshort-lived episodes of activity after the star bursts. Our model predicts\nseveral properties of the low-luminosity AGN including the bolometric\nluminosity, jet powers, the effect on kpc-scale of the radio jet and the AGN\nlifetime, which are in broad agreement with observations of Seyfert galaxies\nand their radio activity.

The\nobservations started 13 days before B-band maximum light and continued for 480\ndays with exceptionally good time sampling. The optical photometry was\ncalibrated through the S-correction technique.\n  The UBVRIJHK light curves and the color indices of SN 2003du closely resemble\nthose of normal SNe Ia. SN 2003du reached a B-band maximum of 13.49 (+/-0.02)\nmag on JD2452766.38 (+/-0.5). We derive a B-band stretch parameter of 0.988\n(+/-0.003), which corresponds to dM15=1.02 (+/-0.05), indicative of a SN Ia of\nstandard luminosity. The reddening in the host galaxy was estimated by three\nmethods, and was consistently found to be negligible. We estimate a distance\nmodulus of 32.79 (+/-0.15) mag to the host galaxy, UGC 9391.

In particular, the Si II\nratio at maximum R(Si II)=0.22 (+/-0.02) and the time evolution of the\nblueshift velocities of the absorption line minima are typical. The pre-maximum\nspectra of SN 2003du showed conspicuous high-velocity features in the Ca II H&K\ndoublet and infrared triplet, and possibly in Si II 6355, lines. We compare the\ntime evolution of the profiles of these lines with other well-observed SNe Ia\nand we suggest that the peculiar pre-maximum evolution of Si II 6355 line in\nmany SNe Ia is due to the presence of two blended absorption components.\n', '[{\"version\":\"v1\",\"created\":\"Tue, 10 Apr 2007 19:53:07 GMT\"}]', '2009-11-13', '[[\"Stanishev\",\"V.\",\"\"],[\"Goobar\",\"A.\",\"\"],[\"Benetti\",\"S.\",\"\"],[\"Kotak\",\"R.\",\"\"],[\"Pignata\",\"G.\",\"\"],[\"Navasardyan\",\"H.\",\"\"],[\"Mazzali\",\"P.\",\"\"],[\"Amanullah\",\"R.\",\"\"],[\"Garavini\",\"G.\",\"\"],[\"Nobili\",\"S.\",\"\"],[\"Qiu\",\"Y.\",\"\"],[\"Elias-Rosa\",\"N.\",\"\"],[\"Ruiz-Lapuente\",\"P.\",\"\"],[\"Mendez\",\"J.\",\"\"],[\"Meikle\",\"P.\",\"\"],[\"Patat\",\"F.\",\"\"],[\"Pastorello\",\"A.\",\"\"],[\"Altavilla\",\"G.\",\"\"],[\"Gustafsson\",\"M.\",\"\"],[\"Harutyunyan\",\"A.\",\"\"],[\"Iijima\",\"T.\",\"\"],[\"Jakobsson\",\"P.\",\"\"],[\"Kichizhieva\",\"M.

The rotational\nbroadening effect on LDRs is also studied. We provide useful calibrations of\neffective temperature versus LDRs for giant and main sequence stars with\n3800<Teff<6000 K and vsini in the range 0-30 km/s. We found that, with the\nexception of very few line pairs, LDRs, measured at a spectral resolution as\nhigh as 42000, depend on vsini and that, by neglecting the rotational\nbroadening effect, one can mistake the Teff determination of 100 K in the worst\ncases.\n', '[{\"version\":\"v1\",\"created\":\"Wed, 11 Apr 2007 17:04:45 GMT\"}]', '2009-11-13', '[[\"Biazzo\",\"K.\",\"\"],[\"Frasca\",\"A.\",\"\"],[\"Catalano\",\"S.\",\"\"],[\"Marilli\",\"E.\",\"\"]]'),

In particular, the\nbilliard chambers describing the asymptotic cosmological behaviour of pure\nEinstein gravity in spacetime dimension d+1, or the metric-three-form system of\n11-dimensional supergravity, are found to be identical to the Weyl chambers of\nthe Lorentzian Kac-Moody algebras AE_d, or E_{10}, respectively. This suggests\nthat these Kac-Moody algebras are hidden symmetries of the corresponding\nmodels.
