Instrumentation for ESO's Extremely Large Telescope
Suzanne Ramsay, Michele Cirasuolo, Paola Amico +21
Design and construction of the instruments for ESO's Extremely Large Telescope (ELT) began in 2015. We present here a brief overview of the status of the ELT Instrumentation Plan.…
On the RR Lyrae stars in globulars: V. the complete Near-Infrared (JHKs) census of omega Centauri RR Lyrae variables
V. F. Braga, P. B. Stetson, G. Bono +35
We present a new complete Near-Infrared (NIR, ) census of RR Lyrae stars (RRLs) in the globular Cen (NGC 5139). We collected 15,472 images with 4-8m class telesc…
On-sky demonstration of matched filters for wavefront measurements using ELT-scale elongated laser guide stars
A. G. Basden, L. Bardou, D. Bonaccini Calia +18
The performance of adaptive optics systems is partially dependant on the algorithms used within the real-time control system to compute wavefront slope measurements. We demonstrate…
GeMS/GSAOI photometric and astrometric performance in dense stellar fields
E. Dalessandro, S. Saracino, L. Origlia +7
Ground-based imagers at 8m class telescopes assisted by Multi conjugate Adaptive Optics are primary facilities to obtain accurate photometry and proper motions in dense stellar fie…
On the radio and NIR jet of PKS 2155-304 and its close environment
E. Liuzzo, R. Falomo, A. Treves +13
PKS 2155-304 is one of the brightest BL Lac object in the sky and a very well studied target from radio to TeV bands. We report on high-resolution (~ 0.12 arcsec) direct imaging of…
The jet of the BL Lacertae object PKS 2201+044: MAD near-IR adaptive optics observations and comparison with optical, radio and X-ray data
E. Liuzzo, R. Falomo, A. Treves +14
Relativistic jets are a common feature of radio loud active galactic nuclei. Multifrequency observations are a unique tool to constrain their physics. We report on a detailed study…
