GalaxiesRedshiftsWe investigate the origin of the huge luminosities produced by high-redshift SCUBA galaxies using the combination of ultra-deep X-ray observations (the 2Ms Chandra Deep Field-North) and deep optical spectroscopic data. Even though a large fraction of high-redshift SCUBA galaxies ...
SPITZER INFRARED LOW-RESOLUTION SPECTROSCOPIC STUDY OF BURIED ACTIVE GALACTIC NUCLEI IN A COMPLETE SAMPLE OF NEARBY ULTRALUMINOUS INFRARED GALAXIES We present the results of Spitzer Infrared Spectrograph low-resolution infrared 5-35 渭m spectroscopy of 17 nearby ultraluminous infrared galaxies (ULIRGs)....
We compare the near- and mid-IR characteristics of these ultra-luminous galaxies to ISO and literature data of thirty starburst and active galactic nuclei (AGN), template galaxies. We find that 1) 70-80% of the ultra-luminous IRAS galaxies in our sample are predominantly powered by recently ...
The associated FIR emission in B6 and B7 and high star formation rates strongly favor star formation in galaxies as an important powering source for the lyman alpha emission in both LABs. However, the other two, B1 and B5, are predominantly driven by the active galactic nuclei or other ...
However, he seriously doubted that there were humanoid life forms in other galaxies. Hawking said that it would be highly unlikely that life-supporting planets elsewhere would mirror lifeforms on Earth to such an extent. He blamed this on our failure to broaden our imagination when it comes to...
There is not enough matter in galaxies to account for their motion. So what did the physicists do? They hypothesized two ad hoc mechanisms, “dark matter” and “dark energy” to explain the missing mass. They still haven’t had success in trying to find evidence for these elusive concepts...
It could coalesce to create organization on all scales, from the smallest microscopic units, called bions in orgone theory, to macroscopic structures like organisms, clouds, or even galaxies. Reich's theories held that deficits or constrictions in bodily orgone were at the root of many diseases...
Dear Lord, I know that I am talking and that no one can hear me, so I suppose I understand a little bit what it has been like to be You. So in this pause, which is not of my own making but of the little hamsters who run in the wheel that powers the internet as they need a...
In a multiverse, one cannot avoid infinity, and infinity does strange things. There are two types of possible infinities in a multiverse: Type I: A single universe may be infinite in size (e.g., in our universe, if space and galaxies would continue forever without end or closure), or ...
6. Celestron C6 Newt - bought as a DSO scope for UK holidays, it did very well in this regard. Compact enough to travel on a parcel shelf and big enough to deliver great views of the Virgo galaxies from a dark sky site. A truly good scope, if one of these comes up (and the ...
