A High Relative-Precision Color-Magnitude Diagram of M67 [PDF]

open access: bronzeMonthly Notices of the Royal Astronomical Society, 2003
We have calibrated an extensive set of BVI observations of M67. We have selected stars that are most likely to be single-star members of the cluster using proper motion, radial velocity, and variability information from the literature, and an examination

Search for extrasolar planets with high-precision relative astrometry [PDF]

open access: bronze, 2008
We present our search program for substellar companions using high-precision relative astronomy. Due to its orbital motion around the star, an unseen substellar companion would produce a periodic "wobble" of the host star, which is the astrometric signal

Dual absolute and relative high precision laser metrology [PDF]

open access: goldInternational Conference on Space Optics — ICSO 2010, 2017
Design, integration, test setup, test results, and lessons-learnt of a high precision laser metrology demonstrator for dual absolute and relative laser distance metrology are presented. The different working principles are described and their main subsystems and performance drivers are presented.

A precise extragalactic test of General Relativity [PDF]

open access: yesScience, 2018
Testing General Relativity on galaxy scales Einstein's theory of gravity, General Relativity (GR), has been tested precisely within the Solar System. However, it has been difficult to test GR on the scale of an individual galaxy. Collett et al.

Precision tests of general relativity with matter waves [PDF]

open access: yesJournal of Modern Optics, 2011
We review the physics of atoms and clocks in weakly curved spacetime, and how each may be used to test the Einstein Equivalence Principle (EEP) in the context of the minimal Standard Model Extension (mSME). We find that conventional clocks and matter-wave interferometers are sensitive to the same kinds of EEP-violating physics. We show that the analogy

Intercalibration of the barrel electromagnetic calorimeter of the CMS experiment at start-up [PDF]

open access: yes, 2008
Calibration of the relative response of the individual channels of the barrel electromagnetic calorimeter of the CMS detector was accomplished, before installation, with cosmic ray muons and test beams. One fourth of the calorimeter was exposed to a beam
