INTRODUCTION








SIMULATION PARAMETERS

    We define H0=100 h km/s/Mpc. The other parameters follow standard notation.



    Cosmological parameters

    LCDM0.30.7 0.70.210.9
    TCDM1.00.0 0.50.210.6





    Collisionless simulation parameters


    The subscripts "hr" and "lr" refer to the high and low resolution regions, respectively.

    N is the number of (DM) particles, M the mass (units Msun/h) of one particle, and lsoft is the physical softening length (units kpc/h).

    Model Nhr Mhr (Msun/h) lsoft,hr (kpc/h) Nlr Mlr (Msun/h) lsoft,lr (kpc/h)
    LCDM 50730389 0.357 x 1010 20 20506522 14.386 x 1010 120
    TCDM 53302154 1.18978 x 1010 20 20442823 47.952 x 1010 120





    Semi-analytic parameters


    fbar is the baryon fraction: fbar=Omegabar/Omega0

    alpha the star formation efficiency, epsilon the SNe feedback efficiency

    fbulge is the ratio of the satellite galaxy mass to the central galaxy mass beyond which a merger is supposed to trigger a starburst and form a bulge component

    "Feedback" gives the hypothesis that we made fot eh fate of the cold gas reheated by the SNe (ejected from the DM halo and later reincorporated or always retained in the halo)

    MB,lum is the luminosity resolution limit of the simulations (in the B band)

    MB,morpho the morphology resolution limit.

    Model fbar alpha epsilon fbulge Feedback MB,lum MB,morpho
    LCDM 0.12 0.05 0.05 0.1 retention -16.25 -18.46
    TCDM 0.2 0.15 0.03 0.1 ejection -18.45 -20.61





    Masses for Milky-Way look-alikes


    Milky Way look-alikes are defined as galaxies of type Sb/Sc with a disk circular velocity betwen 200 and 240 km/s.

    In the table below, masses are given in units of Msun, disk star formation rates in units of Msun/year, and we give our zero-point normalization of the Tully-Fisher realtion.

    Model Stellar mass Cold Gas mass disk SFR MB- 5 log h MI- 5 log h B-V Number
    LCDM 9.32 x 1010 1.05 x 1010 1.78 -20.02 -22.01 0.74 229
    TCDM 1.58 x 1011 1.15 x 1010 3.37 -20.04 -21.99 0.71 941

HALO CATALOGUES






GALAXY CATALOGUES

    We WARN that the use of the galaxy catalogues below, and even around the luminosity resolution limit quoted here requires a lot of caution, and is left to the responsibility of the users !

    So as to be complete, we provide here two full catalogues (with and without dust) which are not cut in resolution. Besides, we also give a catalogue cut at the luminosity resolution limit, not including dust correction, e.g. to obtain a Tully-Fisher relation to be compared to that of Giovanelli et al. (1997).
