AGN feedback from supermassive black holes (SMBHs) at the center of early type galaxies is commonly invoked as the explanation for the quenching of star formation in these systems. The situation is complicated by the significant amount of mass injected in the galaxy by the evolving stellar population over cosmological times. In absence of feedback, this mass would lead to unobserved galactic cooling flows, and to SMBHs two orders of magnitude more massive than observed. By using high-resolution 2D hydrodynamical simulations with radiative transport and star formation in state-of-the-art galaxy models, we show how the intermittent AGN feedback is highly structured on spatial and temporal scales, and how its effects are not only negative (shutting down the recurrent cooling episodes of the ISM), but also positive, inducing star formation in the inner regions of the host galaxy.
Imagine the scene. A river running through a green valley. Under the trees, the river looks like a black-green stream. Pontoons are stretched across the surface, while long lines of tanks wait to cross—sixty-ton behemoths, with the menacing barrels of their 105 mm guns pointing at the opposite shore.
Back in 1979 talk began about stationing Pershing missiles in Europe as a way of renewing Washington's time-worn pledge to its NATO allies and of preventing the U.S. from “decoupling” in Europe. This had the effect of opening a lively debate in foreign policy circles about the missiles per se as well as about the three-decade-old North Atlantic Treaty Organization. Congress took a serious interest, as did the peace movement in Europe. Yet not long ago, when the USSR shot down a Korean civilian airliner, the debate stopped. Such underlying issues as whether NATO should continue in its present form or indeed should exist at all never reached public consciousness.
The world economy and international economic institutions are in trouble. That, at least, is the opinion in informed circles following the Conference on International Economic Cooperation (CIEC) held in Paris last spring. There is a growing realization that CIEC failed to grapple with the systemic problems the world economy faces, a failure that threatens developing and developed countries alike.
Despite Secretary of State Cyrus Vance's dramatic call for a “new international economic system,” the Paris conference failed to address systemic issues. Instead, the developed nations of the North angled for a separation of the issues of energy from those of development; and the developing countries of the South closed ranks by linking the two. Consequently neither side truly debated the crushing problems of the world economy.
It was in May, 1974, at the Sixth Special Session of the United Nations, that a majority of the nations of the world, overriding Western objections, passed a resolution that called for the establishment of a New International Economic Order. This resolution put on a new plane the issues raised in 1964 at the first session of the U.N. Conference on Trade and Development when Raul Prebisch, the UNCTAD secretary general, had called in his opening speech for a new international order.
Since 1974 a number of conferences and discussions have been held about how to implement the new order. In 1975, in the wake of a memorable speech read by then U.N. Ambassador Daniel Patrick Moynihan that reflected a more conciliatory posture by Secretary of State Henry Kissinger, the U.N. Seventh Special Session passed a revised declaration.
For the past four years right-wing and left-wing organizations in the United States have been aware of a new foreign policy establishment known as the Trilateral Commission. This group, founded by David Rockefeller, is comprised largely of corporate executives from Western Europe, Japan, and the U.S. Jimmy Carter, Walter Mondale, Zbigniew Brzezinski, and Cyrus Vance, as well as seventeen other members and former members of the Carter administration, belonged to this group before they took office. Key political figures in the governments of Japan and Western Europe also belong, as do John Anderson, George Bush, and Henry Kissinger.
A crucial turning point in geopolitical history occurred on November 1, 1978, when President Carter announced a massive borrowing of foreign currencies to save the U.S. dollar. For the first time since World War II the U.S. was forced to borrow from the International Monetary Fund; and for the first time since 1893 the U.S. Treasury will have to issue bonds denominated in foreign monies—in this case Japanese yen, West German marks, and Swiss francs.
What all this means is that the U.S. has acknowledged two things: that the European Economic Community (the EEC) and Japan are now its economic equals; and that America has forfeited the international economic supremacy it enjoyed since 1915.
