An Analysis of Large Astronomical Detector Controller Systems and Implications for Future ESO Detector Systems
Mathias Richerzhagen, Naidu Bezawada, Sebastian Elias Egner +11
Large astronomical instruments using tens to hundreds of optical or infrared science detectors pose specific challenges for detector control, where, in addition to performance, oth…
System Design of the Newest Generation Detector Controller for ELT and new VLT Instruments
Mathias Richerzhagen, Matthias Seidel, Leander Mehrgan +4
A new detector controller, NGCII, is in development for the first-generation instruments of the ELT as well as new instruments for the VLT. Building on experience with previous ESO…
The status of the NIR arm of the SOXS Instrument toward the PAE
Fabrizio Vitali, Matteo Genoni, Matteo Aliverti +57
The Son Of X-Shooter (SOXS) is a single object spectrograph, built by an international consortium for the 3.58-m ESO New Technology Telescope at the La Silla Observatory [1]. It of…
Characterisation and assessment of the SOXS Spectrograph UV-VIS Detector System
R. Cosentino, M. Hernandez, H. Ventura +50
The SOXS spectrograph, designed for the ESO NTT telescope, operates in both the optical (UV-VIS: 350-850 nm) and NIR (800-2000 nm) bands. This article provides an overview of the f…
Progress on the SOXS transients chaser for the ESO-NTT
P. Schipani, S. Campana, R. Claudi +53
SOXS (Son Of X-Shooter) is a single object spectrograph offering a simultaneous spectral coverage from U- to H-band, built by an international consortium for the 3.58-m ESO New Tec…
HiPERCAM: a quintuple-beam, high-speed optical imager on the 10.4-m Gran Telescopio Canarias
V. S. Dhillon, N. Bezawada, M. Black +36
HiPERCAM is a portable, quintuple-beam optical imager that saw first light on the 10.4-m Gran Telescopio Canarias (GTC) in 2018. The instrument uses re-imaging optics and 4 dichroi…
Mid-infrared circumstellar emission of the long-period Cepheid l Carinae resolved with VLTI/MATISSE
V. Hocdé, N. Nardetto, A. Matter +149
The nature of circumstellar envelopes (CSE) around Cepheids is still a matter of debate. The physical origin of their infrared (IR) excess could be either a shell of ionized gas, o…
Development status of the UV-VIS detector system of SOXS for the ESO-NTT telescope
Rosario Cosentino, Marcos Hernandez, Hector Ventura +47
SOXS will be the new spectroscopic facility for the ESO NTT telescope able to cover the optical and NIR bands by using two different arms: the UV-VIS (350-850 nm), and the NIR (800…
Development status of the SOXS spectrograph for the ESO-NTT telescope
P. Schipani, S. Campana, R. Claudi +51
SOXS (Son Of X-Shooter) is a single object spectrograph, characterized by offering a wide simultaneous spectral coverage from U- to H-band, built by an international consortium for…
Performance advantages of buffered mode operation of HxRG near infrared detectors
Naidu Bezawada, Derek Ives, Domingo Alvarez +4
The Teledyne HxRG detectors have versatile and programmable output options to allow operation of them in a variety of configurations such as slow unbuffered, slow buffered, fast bu…
Detector Systems Engineering for Extremely Large Instruments
Elizabeth M. George, Naidu Bezawada, Derek Ives +22
The scientific detector systems for the ESO ELT first-light instruments, HARMONI, MICADO, and METIS, together will require 27 science detectors: seventeen 2.5 m cutoff H4RG-15 d…
The asymmetric inner disk of the Herbig Ae star HD 163296 in the eyes of VLTI/MATISSE: evidence for a vortex?
J. Varga, M. Hogerheijde, R. van Boekel +133
Context. The inner few au region of planet-forming disks is a complex environment. High angular resolution observations have a key role in understanding the disk structure and the…
An image of the dust sublimation region in the nucleus of NGC 1068
