2017/504c - Atmospheric Dispersion Correction for High Resolution Astronomical Instruments

Advisors: Alexandre Cabral (IA U.Lisboa), Gerardo Ávila Soberanes (ESO)

This proposal is focused on the development of Atmospheric Dispersion Correctors for current astronomical instruments where the recent developments in the field of adaptive optics systems, improving considerably the performances of telescope resolution, and the arrival of large telescopes with diameters up to 40 m, reinforce the need to revisit the way differential atmospheric dispersion is corrected and how it influences the performances of high resolution spectrographs.

The work for this proposal will cover both the Study of the atmospheric dispersion phenomena and how it influences astronomical observations and the analysis and development of Atmospheric Dispersion Correctors (ADC). All will be supported by the work on three case studies, each one on a different astronomical instrument: the already installed Espresso ADC, the current NIRPS ADC and the future E-ELT HIRES ADC(s)

2017/505 - Metrology of stabilized laser sources for gravitational wave detectors

Advisors: Manuel Adler Abreu (IA U.Lisboa & FCUL), Alexandre cabral (IA U.Lisboa & FCUL)

This proposal is focused on the development of metrology concepts and testbeds for testing and verification of noise characteristics of highly stabilised laser sources. These laser sources have critical importance on the global uncertainty of high precision interferometry techniques being implemented for the gravitational wave detectors, but also play a major role for nanoscale dimension metrology and other high accuracy measurement techniques. The work to be implemented by the student comprises the evaluation of the current lasers sources with such stringent requirements, the assembly of experimental setup for the stabilisation of a suitable laser source and the development of tools that will allow to verify the performance of such device.
