1. Global Schmidt Law Kennicutt1998 Gao & Solomon 2004

2. Star Formation Thresholds Martin & Kennicutt (2001)

Models of the SF laws Gravitational instability (Kennicutt89, Friedli et al. 94, Kennicutt98, Martin & Kennicutt 01) Kinematical law (Wyse 86, Silk 87, Hunter, Elmegreen & Baker 98) Density PDF from turbulence (Elmegreen 02, Kravtsov03, Krumholtz & McKee 05)

P1: SF in Isolated Disks Code: GADGET v1.1 (Springel, Yoshida & White 01) + sink particles (gravitationally bound, convergent flow, n >10 3 cm -3, represent star clusters) Galaxy model:  DM halo + disk (stars & isothermal gas) (Mo, Mao, White 98, Springel & White 99, Springel 00) Initial conditions: –rotational vel.: 50 ≤ V rot ≤ 220 km s -1 –gas fractions: 20 ≤ fg ≤ 90% of Md –effective sound speed cg = 6, 15 km s -1

Numerical Criteria Jeans criterion for mass resolution (Bate & Burkert 97, Truelove et al. 97) Gravity-hydro balance criterion for gravitational softening length (Bate & Burkert 97) Equipartition criterion between gas, collisionless particle masses (Steinmetz & White 97)

Connection btw SF and BH Growth Similarity btw cosmic SFH and quasar evolution (Madau et al. 96, Shaver et al 96) Starburst – AGN connection (Norman & Scoville 88, Smith, Lonsdale & Lonsdale 98) M BH –  correlation (Magorrian et al. 98, Ferrarese & Merritt 00, Tremaine et al. 02) Most starburst gals are mergers (Sanders & Mirable 96, Alexanders et al 2004) Larger amount of CO in nearby merging galaxies (Scoville 2000) and high-z QSOs (Walter 2002) QSO lifetimes 10 6 – 10 8 yrs (Martini 2004) Recent simulations (De Mateo, Springel & Hernquist 05, Kazantzidis et al. 05)

Simulated M BH -  Relation Li, Haiman & Mac Low, in prep

Quasar Lifetimes Li, Haiman & Mac Low, in prep

Summary Our simulations reproduce many obs. of SF in gals -- the Schmidt Laws, SF thresholds…  tot  gravitational instability,  CO  SFE Galaxy interaction trigger starburst. Higher S N of GCs, and bimodal metallicity dist. are natural products of gas-rich major mergers. Merger also increase BH accretion, and the M BH –  correlation is the fine-tuning of gas removal, in our case regulated by SF. Quasar lifetime ranges 10 6 – 10 8 yrs, depending on the luminosity threshold
