Development of an adaptive optics testbed at MPIA for the ELT/Planetary Camera and Spectrograph (PCS)
Raphaël Pourcelot, Thomas Bertram, Peter Bizenberger +5
The Planetary Camera and Spectrograph (PCS) is a proposed second-generation instrument for the Extremely Large Telescope (ELT), dedicated to the direct imaging and characterization…
Assembly, integration, and verification of MITESI: an optical testbed for simulating the ELT in the laboratory
Daniel J Ahrer, M. Concepción Cárdenas Vázquez, Thomas Bertram +5
MITESI is an optical testbed which simulates key characteristics of the ELT, ultimately producing an artificial natural guide star. It was designed primarily to enable testing of t…
Discovery of a star sensitive to the spin of Sgr A*
K. Abd El Dayem, R. Abuter, N. Aimar +85
The paper reports the discovery of a faint main‑sequence star (S301) on an 8.7‑year, highly eccentric orbit around the Milky Way’s central black hole, whose high velocity makes its…
A 5kHz modulator for pyramid wavefront sensors
Maximilian Häberle, Vianak Naranjo, Yared Reinarz +5
Despite the emergence of new types of wavefront sensors, the modulated pyramid wavefront sensor remains the workhorse for ELT instrumentation, and is among the options even for adv…
SIMTERFERE: An optical interferometry simulator for quantifying the coherent flux stability of VLTI/GRAVITY+. Reaching per mill stability: Application to exoplanet spectroscopy
J. R. Sauter, A. von Stauffenberg, G. Bourdarot +7
The implementation of the GRAVITY+ Adaptive Optics (GPAO) system at VLTI enables unprecedented sensitivity and stability in optical interferometry. This allows high-precision chara…
Exploring the presence of a fifth force at the Galactic Center
The GRAVITY Collaboration, K. Abd El Dayem, R. Abuter +60
Aims: The presence of a Yukawa-like correction to Newtonian gravity is investigated at the Galactic Center, leading to a new upper limit for the intensity of such a correction. Met…
