Discussing the complacency and complicity of traditional economic models, as taught in universities and adopted by central banks, Michael and Steve take us on a journey from a solar system to a galaxy of thought, taking in the history of economics to solutions for the ongoing global depression.

Galaxies that appear redder have high values for both of these measurements, meaning that the mass of the bulge — and central black hole — determines their colour.

For the past two years, a group calling itself the MACHO collaboration, which includes astronomers in the US, Australia and Britain, has monitored the brightness of stars in the central «bulge» of our Galaxy and in a satellite galaxy known as the Large Magellanic Cloud.

For many years, astronomers had a simple view of our Milky Way's central hub, or bulge, as a quiescent place composed of old stars, the earliest homesteaders of our galaxy.

A light drizzle of cooling gas provides enough fuel for the central black hole's jets to keep the rest of the galaxy's gas hot.

Astronomers can't wait for the gas cloud known as G2 to reach our galaxy's central supermassive black hole, as shown in this simulation.

This sounds reasonable at first, but host galaxies are 10 billion times bigger than the central black holes; it should be difficult for two objects of such vastly different scales to directly affect each other.

«Using measurements that were done at BYU, we were able to determine that the mass of the central black hole for this galaxy was about 8 million times the mass of the sun — that's a really really massive object.»

To test whether this is really happening, Bramante suggests looking for type Ia supernovae in areas with lots of dark matter, the central region of a galaxy, say, and checking to see if their progenitor stars differ from what we expect.

Using a similar technique, but out of a different sample, NGC 1277 was identified as unique in that it has a central black hole that is much more massive than it should be for a galaxy of that size.

NIRC2 is probably best known for helping to provide definitive proof of a central massive black hole at the center of our galaxy.

The telescope's sensitivity and wide view will enable a large - scale search for exoplanets by monitoring the brightness of millions of stars in the crowded central region of our galaxy.

For reasons not fully understood, it appears that the sizes of central black holes and the masses of their galaxies, especially the central bulges, are almost perfectly in step [perfectly correlated].40

Here's the problem for those who believe a big bang preceded the formation of black holes, stars, and galaxies: black holes are too small to affect something as huge as a galaxy that formed long after the universe expanded, and there is no reason a galaxy should form a large central black hole.

Young, mostly sun - like stars in the core, or central bulge, provided the building blocks for the galaxy's foundation.

Evidence has been accumulating for several decades that most galaxies harbor central mass concentrations that may be in the form of black holes with masses between a few million to a few billion times the mass of the sun.

In most galaxies the central black hole would have been smaller than the billions of solar mass black holes for quasars.

This sharpest - ever image, taken in January 2005 with the Advanced Camera for Surveys aboard the NASA / ESAHubble Space Telescope, illustrates a spiral galaxy's grand design, from its curving spiral arms, where young stars reside, to its yellowish central core, a home of older stars (Credit: NASA, ESA, S. Beckwith (STScI), and The Hubble Heritage Team (STScI / AURA)-RRB-

Recent investigations have brought up support for the assumption that the Milky Way may even have a pronounced central bar like barred spiral galaxies M58, M91, M95, or M109, and thus be of Hubble type SBb or SBc.

A galaxy's core size typically is correlated to the dimensions of its host galaxy, but in this case, the central region is much larger than astronomers would expect for the galaxy's size.

In each of the three bands, we have not detected a signature of the central excess component in contrast to the previous report on the det... ▽ More We have undertaken a search for the infrared emission from the intracluster dust in the Coma cluster of galaxies by the Multiband Imaging Photometer for Spitzer.

That the sculptures appear anthropomorphic and organic is essential to a reading of the work: the spiralling central to Nepomuceno's process relates to the spirals occurring naturally throughout the universe, giving shape to entire galaxies as well as the blueprint for existence, DNA.

Bluntly stated, yet with great respect; the law has spent more than forty years looking for the true jurisdictional question, twenty years trying to assess the relative expertise of tribunals, ten years trying to convince everyone of a meaningful distinction between two deferential standards of review and now another possible lifetime wandering the administrative galaxy looking for questions of law of central importance to the legal system.
