Advances in Edge Sensors for the Thirty Meter Telescope Primary Mirror
Extremely Large Telescopes edge sensors segmented mirrors
2015/5/12
The primary mirror segments are passively constrained in the three lateral degrees of freedom. We evaluate the segment
lateral motions due to the changing gravity vector and temperature, using site ...
Design of a Prototype Primary Mirror Segment Positioning Actuator for the Thirty Meter Telescope
TMT actuator control system
2015/5/12
In order for the Thirty Meter Telescope (TMT) to achieve the required optical performance, each of its 738 primary
mirror segments must be positioned relative to adjacent segments with nanometer-lev...
The Thirty Meter Telescope project will design and build a thirty-meter diameter telescope for research in astronomy at
optical and infrared wavelengths. The highly segmented primary mirror will use...
Control and support of 4-meter class secondary and tertiary mirrors for the Thirty Meter Telescope
Mirror support articulation figure contro
2015/5/12
The Thirty Meter Telescope (TMT) project is a partnership between ACURA, AURA, Caltech, and the University of
California. The design calls for a 3.6 m diameter secondary mirror and an elliptical ter...
Development of the Primary Mirror Segment Support Assemblies for the Thirty Meter Telescope
TMT segment mirror support
2015/5/12
This paper describes the studies performed to establish a baseline conceptual design of the Segment Support Assembly (SSA) for the Thirty Meter Telescope (TMT) primary mirror. The SSA uses a combinat...

Intermediate-mass-ratio-inspirals in the Einstein Telescope. II. Parameter estimation errors
Intermediate-mass-ratio-inspirals Einstein Telescope
2010/12/20
We explore the precision with which the Einstein Telescope (ET) will be able to measure the
parameters of intermediate–mass–ratio inspirals (IMRIs), i.e., the inspirals of stellar mass compact object...
Fermi Gamma-ray Space Telescope: High-Energy Results from the First Year
Gamma-ray Space Telescope High-Energy Results First Year
2011/1/5
The Fermi Gamma-ray Space Telescope (Fermi) was launched on June 11, 2008 and began its
first year sky survey on August 11, 2008. The Large Area Telescope (LAT), a wide field-ofview
pair-conversion ...
