SUMMARY:Atomic to cosmic scales: reducing thermal noise in gravitational wa
 ve detectors - Riccardo Bassiri (LIGO)
DESCRIPTION:Atomic to cosmic scales: reducing thermal noise in gravitationa
 l wave detectorsRiccardo BassiriSenior Research Scientist\, Stanford LIGO 
 GroupDeputy Director\, LSC Center for Coatings Research
Abstract: The dete
 ctions of gravitational waves from coalescing black holes and neutron star
 s by the Advanced LIGO and Advanced Virgo detectors has launched the new e
 ra of gravitational wave astronomy. Increasing the sensitivity of the dete
 ctors several times would increase the number of gravitational waves and t
 he types of events observed. Therefore\, an international research effort 
 is currently underway to increase the sensitivity of future generations of
  gravitational wave detectors\, such as Advanced LIGO +\, by addressing th
 e dominant noise source limiting their performance: thermal noise in the a
 morphous dielectric mirror coatings used in the detector optics.
The devel
 opment of mirrors with low thermal noise requires progress in the understa
 nding of the physics of mechanical losses in amorphous materials\, and how
  these relate to growth parameters and structure. This presentation will p
 rovide an overview of the ongoing research to identify lower mechanical lo
 ss. Recent results will be presented from X-ray scattering combined with a
 tomic modeling\, which aim to understand the nature of the two-level-syste
 ms thought to be responsible for the observed mechanical loss\, test strat
 egies to reduce it\, and inform the design of new coating materials for ma
 nufacturers to develop.
Bio: Dr. Bassiri co-ordinates the materials resear
 ch efforts of the group. His research focuses on studying the materials us
 ed in the gravitational wave detector optics\, for both current and future
  generations of detectors. Dr. Bassiri also holds an Honorary Research Fel
 low position at the University of Glasgow\, Scotland.

 his speaker\, we can consult his web page at the Stanford LIGO group.
