"The First Galaxies in the Universe"

Astronomy professor Steven Furlanetto and colleague Abraham Loeb have written a new book, "The First Galaxies in the Universe," now available.  

This book provides a comprehensive, self-contained introduction to one of the most exciting frontiers in astrophysics today: the quest to understand how the oldest and most distant galaxies in our universe first formed. Until now, most research on this question has been theoretical, but the next few years will bring about a new generation of large telescopes that promise to supply a flood of data about the infant universe during its first billion years after the big bang.

The Air Force YIP supports scientists and engineers who have received Ph.D. or equivalent degrees in the last five years and show exceptional ability and promise for conducting basic research.
 
The objective of this program is to foster creative basic research in science and engineering; enhance early career development of outstanding young investigators; and increase opportunities for the young investigator to recognize the Air Force mission and related challenges in science and engineering.
 
Wes Campbell has been awarded this prestigious Airforce Young Investigator Research Program grant for exceptional ability and promise in basic research. Professor Cambell's research uses ultra-cold atoms and molecules to learn about the physical processes that permeate our world. We are specifically focused on the physics of quantum mechanical systems that involve many-body interactions, where our ability to theoretically describe and numerically simulate the microscopic features is severely limited.

Research

 
 
The effect of an asteroid hitting Earth can be — and has been — devastating. Radar astronomy plays a critical role in evaluating and mitigating the risks associated with such asteroid impacts.
 
UCLA asteroid expert Jean-Luc Margot recently spoke about using radar astronomy to monitor and respond to asteroid threats at the third Planetary Defense Conference of the International Academy of Astronautics, in Flagstaff, Arizona.  
 
In a four-minute video, Professor Margot, a member of both the departments of Earth, Planetary and Space Sciences and Physics & Astronomy, describes some of the radar astronomy research conducted in his UCLA laboratory.

3D images of structural defects inside a platinum nanoparticle at atomic resolution

Scientists at the University of California, Los Angeles have found a way to create stunningly detailed three dimensional representations of platinum nanoparticles at an atomic scale. These are being used to study tiny structural irregularities called dislocations. Professor John Miao has been at the forefront of this study.

UCLA physicists have pioneered a new technique that combines two traditional atomic cooling technologies and brings normally springy molecules to a frozen standstill. Their research was published March 28 in the journal Nature.
 
"Scientists have been trying to cool molecules for a decade and have succeeded with only a few special molecules," said Eric Hudson, a UCLA assistant professor of Physics and the paper's senior author. "Our technique is a completely different approach to the problem — it is a lot easier to implement than the other techniques and should work with hundreds of different molecules."

Accelerating a free electron with a laser has been a longtime goal of high-energy physicists.
 
David Cline, a distinguished professor in the UCLA Department of Physics & Astronomy, and Xiaoping Ding, an assistant researcher at UCLA, have conducted research at Brookhaven National Laboratory in New York and have established that an electron beam can be accelerated by a laser in free space.
 
This has never been done before at high energies and represents a significant breakthrough, Cline said, adding that it also may have implications for fusion as a new energy source.

The Scientist highlights John Miao's pioneering work on extending X-ray crystallography to allow structural determination of non-crystalline specimens. "It took us a while," Miao concedes. For one thing, the virus measures only 150–200 nm in diameter, whereas the synchrotron beam is about as wide as the thinnest human hair, perhaps 20 μm.
 
Getting the two to line up in complete darkness inside a large vacuum chamber took some doing, he says. In the end, Miao's team first used a "high-resolution optical microscope" to locate individual virus particles on the membrane. They then inserted the membrane into the chamber and scanned it relative to the X-ray beam while watching for diffraction signals. After 10 days of around-the-clock effort, they finally succeeded.
 
The resulting diffraction pattern yielded a low-resolution structure of a single herpes virus virion, the first time such an image had ever been obtained. But at 22-nm, or 220-Å, resolution, the virus does not look like a classical virus so much as a niblet of corn, or perhaps an asteroid (see image at right). "We can see the capsid and the membrane, but not much detail," Miao says.

UCLA Daily Bruin article by James Rosenzweig, Chair, Physics & Astronomy 
 
Professor Rosenzweig states in this article the fact that, despite bipartisan acknowledgment of the essential role of research and development, funding for physical science research in the United States has remained stagnant for three decades. UCLA has benefitted from strong growth in extramural research support with the impressive enhancement of the school's reputation.
 
UCLA is second or third in the nation in research support received, and UCLA's physical sciences were rated ninth in the world according to an article in The Times of London. Excellence in graduate programs is directly tied to the success in obtaining research support, mainly from the federal government.
 
Rosenzweig states that in recent years there has been a reorganization of American science funding priorities, resulting in some outstanding research. On the other hand, established researchers get recognition and funding, while young investigators at the start of their career struggle to get research funding.
 
Programs such as the Large Hadron Collider in Switzerland and the International Thermonuclear Experimental Reactor project are both located in Europe. With U.S. support being so erratic, long term undertakings will work against this countries ability to host first class projects. Professor Rosenzweig fears that with looming budget cuts the future of U.S. science would destroy the U.S. standing in the world, producing lasting harm.
 
Students and postdoctoral researchers who might consider UCLA for their program of study will simply choose to go elsewhere to find more welcoming and stable conditions. The scientific community and concerned citizens have to stand up to needless damage of our economic and intellectual futures. This article was included in our Physics & Astronomy 2011 - 2012 Annual Report.

Educational initiatives

 
New quantum optics laboratory class
 
New this year is our new upper division undergraduate experimental quantum mechanics laboratory created by Professor Eric Hudson. Taught for the first time is a new laboratory class on experimental quantum optics. In this class, students use tools of modern optics to generate and study entangled photons, culminating in the violation of Bell's inequality and the observation of the interference of two photons. 

 

This year Professor Roberto Peccei taught an upper division physics elective "The Physics of Energy." As one may anticipate from the timeliness of the topic, the course was extremely popular. It was successful at harnessing the physics training of our undergrads to give them an appreciation of the fundamentals for this field, which is of central importance in our collective economic and environmental futures.

 

 

In the works

Professor Dolores Bozovic is working on creating a new upper division physics elective "Polymer Physics," which has a broad range of applications to actively expanding fields of current research. Specifically the course is intended to provide the students with the theoretical background for topics in soft condensed matter and biological physics.

Professor James Larkin is working on a new GE course, "Revolutions in Physics," which will focus on developments of the 20th century including relativity, quantum mechanics and cosmology. We believe this material will be exciting to many students as these topics are also key to understanding our increasingly technical world. Emphasis will be placed on how our more modern understanding of the physical world led to such everyday conveniences as GPS satellites, microwave ovens, semiconductors, and nuclear power.
