Greatest Physicists #9 - J.J Thomson [Built on Facts]

#9 - J.J. Thomson The entire edifice of chemistry is a theme and variation on the study of the properties of atomic electrons. Tremendous sections of physics, from solid state to quantum optics to AMO and beyond hings almost entirely on electron behavior. Astrophysics, spectroscopy, and large chunks of high energy physics rely on the understanding of the electron. And those are just the leading edge of what the electron means to modern science. More than anyone else, we owe J.J. Thomson for

Pinning down the Milky Way’s spin September 19th, 2008 New, very precise measurements have shown that the rotation of the Milky Way is simpler than previously thought. A remarkable result from the most successful ESO instrument HARPS, shows that a much debated, apparent ‘fall’ of neighbourhood Cepheid stars towards our Sun stems from an intrinsic property of the Cepheids themselves.

Hallo everybody! ^_^ Man, I’m soo happy. Today, I finished my first week of the fisrt semester of my sophmore year (hope it stays sophmore and doesn’t become a suffer-more year :P) anyways, I’m just plain happy. I love all the courses I choose this semester… all.. except one: biology. But before I rattle on about why I dislike it, I shall first talk about the ones I do like! So this semester, we have to take Theoretical Mechanics and Electrodynamics, as well as Physics Lab as department r

XMM-Newton Discovers Periodic Signal in Black Hole. XMM-Newton has uncovered a well-tuned periodic signal from a super-massive black hole lodged at the centre of a galaxy, ending a long quest for such an object. The discovery provides scientists with a clearer picture on black hole accretion processes and an excellent tool to study active galactic nuclei (AGNs). These periodic signals originating from the black hole are emitted in X-rays, which are blocked out by the Earth's atmosphere.

Star Trackers Lights the Way
FigBranchcom
3 min - 19 Sep 2008

Narration:The concept of a Star Tracker probably can be traced back to the early sailors who used to navigate the open seas. The concept is they use star field patterns in order to tell them where theyre pointed, while they are sailing from east to west or north to south, whatever direction they were going.The Star Tracker is a lot more complicated in that it uses the entire star field pattern to provide attitude knowledge or, in the laymens term, more of the direction in which the spacecraft is pointing while it is orbiting the Earth or doing wherever its science mission requires it to do. So, essentially, its an optical device to access the eyes of the spacecraft.The Star Tracker was built for the Lunar Reconnaissance Orbiter and the Solar Dynamics Observatory, both NASA missions in Florence, Italy by Galileo Avianica. They write their own software used to operate the star trackers, ground all of their optics, fabricate the structures, and assemble and test the electronics.Once the star trackers are assembled, Galileo Avionica works with NASA engineers in order to ensure that the star trackers are built to achieve their performance requirement as well as their environmental requirement. The LRO and SDO missions both use two star trackers for redundancy, so that if you get a fair unit in one, the second star tracker will be used as the backup.Also, the use of two star trackers provided added or increased performance accuracy so that the spacecraft will have a more accurate knowledge of where it's pointed while its orbiting either the moon, the Earth, or the Sun. NASA is an educational extension of the government.Through all the information we get from all our various missions, we learn things about our Earth, space, how space effects Earth, and our changing environment. All of these things are important to everyone in the world, whether we know it our not, and the importance of star tracker, is they act as the eyes of the satellite to let the satellite know where its going in order to get the information we need.For more visit us at www.figbranch.com

Archaeology of the Stars
FigBranchcom
7 min - 18 Sep 2008

Timothy Beers, professor of astronomy and physics at Michigan State University, discusses his research on the formation of the earliest stars in the universe. The first stars born out of the Big Bang were very massive with short lives and exploded. Low mass stars formed shortly after these massive stars. Their atmospheres contain elemental abundances produced from the massive stars. From this evidence, we are learning how elements heavier than hydrogen and helium formed. This helps us to understand the murkiest part of the universe's history, the story at the beginning. One star showed a strong signature of R-process elements that are found at the end of the periodic table. The abundance of Uranium-238 and Thorium-232 provides two atomic clocks. If you measure the rate of the ticking, then you can find when the ticking began.To find out more, please visit us at http://figbranch.com/index.php?option=com_content&task=view&id=475&Itemid=32Credit: NSCL

AGN Heating 3D Simulation (rich galaxy cluster; B2)
MaxGaspari
1 min - 17 Sep 2008

Advanced hydrodynamical and astrophysical 3D simulation of a jet outflow, generated from an active galactic nucleus at the center of a rich galaxy cluster (10^15 Msun). It was computed with YGUAZU'-A code (in FORTRAN language), in order to study the problem of cooling flow in these cosmological systems.The video refers to the specialistic thesis of Massimo Gaspari, entitled ''Cooling vs. Heating in galaxy clusters and groups & hydrodynamical 3D simulations with AGN outflow''. It shows an evolution of the density map (xz plane through center) with the temperature levels and velocity field superimposed. Each frame represents a timestep of 5 Myr; total time of integration is 820 Myr. The box is 100 kpc in size: the central region of a rich glaxy cluster (e.g. A1795).The model is B2: the feedback of the AGN outflow is self-regulated (B) by the accretion on the BH with an efficieny of 0.001 (2). This is one of the best models: cooling rate are ~1-10% of the cooling flow standard model; the central temperature, density and SB profiles resembles the observational data (s. thesis); the evolution of the map (in the video) shows the typical X-bubbles and weak shocks (s. Perseus).

This is an extreme model (bad): cooling rate are ~1% of the cooling flow standard model; the central temperature (too high), density and SB profiles (too low) don't resemble the observational data (s. thesis); the evolution of the map (in the video) doesn't show the typical X-bubbles and weak shocks (s.

It shows an evolution of the density map (xz plane through center) with the temperature levels and velocity field superimposed. Each frame represents a timestep of 10 Myr; total time of evolution is 870 Myr. The box is 28 kpc in size: the central region of a galaxy group (e.g. NGC 5044).The model is B3: the feedback of the AGN outflow is self-regulated (B) by the accretion on the BH with an efficieny of 0.00001 (3). This is one of the best models for galaxy group: the central temperature, density and SB profiles resemble the observational data (s. thesis); the evolution of the map (in the video) shows very small X-bubbles and weak shocks (need more resolution). The cooling rate is not much reduced: ~70% of the cooling flow standard model; but it seems that galaxy groups don't need a strong heating (s. T and n profile of NGC 5044) like clusters.
