Longstanding Quasar Puzzle Solved

New KIAA faculty member Yue Shen and KIAA Director Luis Ho have solved a two-decade long mystery in quasar research. Namely, what drives the diverse properties of quasars into a well-defined main sequence, known as "Eigenvector 1", where many physical quasar properties correlate with the strength of optical FeII strength. Shen and Ho used archival data from the Sloan Digital Sky Survey, combined with other multi-wavelength data, to show conclusively that Eddington ratio (the efficiency of BH accretion) is the main driver of EV1. Their work is published in the September 11 issue of the journal Nature.

A New Strategy to Directly Measure the Acceleration of the Universe

Future radio surveys of intergalactic hydrogen clouds could offer the first direct measurement of the Universe’s acceleration. By far, the primary support for cosmic acceleration comes from supernova data, which is indirect, as it assumes the validity of Einstein’s general relativity and that the Universe is homogeneous, in order to derive equations that relate distance to velocity and luminosity. In a paper recently published in the July 24 issue of Physical Review Letters, CITA-KIAA Joint Postdoctoral Fellow Hao-Ran Yu and his colleagues investigated the potential of using dense hydrogen clouds for a direct acceleration measurement.

CHILI "Cook-off" Meeting to be held at KIAA

The China Lijiang IFU (CHILI) project's inaugural "cook-off" meeting will be held in KIAA-PKU on November 15, 2014. This is the first time the CHILI science team members, including over 50 active scientists and engineers, will meet together and discuss CHILI's science capabilities and execution plans. This meeting will mark the start of CHILI as a scientific project. The meeting is jointly organized by the KIAA and the Shanghai Astronomical Observatory.

Two Hubble Fellows Join the Faculty

KIAA has recruited two new faculty members. Yue Shen, an expert on quasars and active galaxies, received his PhD from Princeton University in 2009, worked at the Harvard-Smithsonian Center for Astrophysics as a Clay Postdoctoral Fellow, and then at the Carnegie Observatories as a Hubble Fellow. He received the Youth Qian Ren honor in 2014. Linhua Jiang is an extragalactic astronomer whose research interests include high-redshift quasars and galaxies and observational cosmology. He received his Ph.D. from University of Arizona in 2008, and then became a Postdoctoral Fellow there. Since 2011, he has worked as a Hubble Fellow at Arizona State University.

Cover Feature on KIAA in the Asia Pacific Physics Newsletter

An article highlighting KIAA appears in the August 2014 issue of the Asia Pacific Physics Newsletter (APPN), a publication devoted to "reporting frontier discoveries in physics, research highlights, and news to facilitate interaction, collaboration and cooperation among physicists in Asia Pacific physics community."

Announcing the 2014 KIAA-PKU Astrophysics Forum

The 2014 KIAA-PKU Astrophysics Forum will focus on the topic, "Thirty Meter Telescope in China: Scientific and Technological Frontiers". It will be held November 2-4, 2014 at the KIAA at PKU, and co-hosted by the KIAA, PKU, and the NAOC. TMT will be one of the most powerful telescopes in the history of astronomy, and it will be one of the greatest astronomical facilities China will possess in the beginning of the 21st century. It will bring unprecedented opportunity to Chinese astronomy. How to achieve scientific and technical readiness for TMT to maximize its impact is a great challenge that the Chinese astronomy community is facing.
