Recent and Upcoming Upgrades for MIRC-X and MYSTIC on the CHARA Array
Noura Ibrahim, Mayra Gutierrez, John D. Monnier +17
MIRC-X and MYSTIC are six-telescope near-infrared beam (1.08-2.38 m) combiners at the CHARA Array on Mt Wilson CA, USA. Ever since the commissioning of MIRC-X (J and H bands) in…
The GRAVITY+ Project: Towards All-sky, Faint-Science, High-Contrast Near-Infrared Interferometry at the VLTI
GRAVITY+ Collaboration, :, Roberto Abuter +134
The GRAVITY instrument has been revolutionary for near-infrared interferometry by pushing sensitivity and precision to previously unknown limits. With the upgrade of GRAVITY and th…
Beam combiner for the Asgard/BIFROST instrument
Daniel J. Mortimer, Sorabh Chhabra, Stefan Kraus +4
BIFROST will be a short-wavelength ( = 1.0 - 1.7m) beam combiner for the VLT Interferometer, combining both high spatial (/2B = 0.8 mas) and spectral (up to R = 25,000) re…
High spectral-resolution interferometry down to 1 micron with Asgard/BIFROST at VLTI: Science drivers and project overview
Stefan Kraus, Daniel Mortimer, Sorabh Chhabra +10
We present science cases and instrument design considerations for the BIFROST instrument that will open the short-wavelength (Y/J/H-band), high spectral dispersion (up to R=25,000)…
MIRC-X: a highly-sensitive six telescope interferometric imager at the CHARA Array
Narsireddy Anugu, Jean-Baptiste Le Bouquin, John D. Monnier +11
MIRC-X (Michigan InfraRed Combiner-eXeter) is a new highly-sensitive six-telescope interferometric imager installed at the CHARA Array that provides an angular resolution equivalen…
Modeling the e-APD SAPHIRA/C-RED ONE camera at low flux level: an attempt of photon counting in the near-infrared with the MIRC-X interferometric combiner
C. Lanthermann, N. Anugu, J. -B. Le Bouquin +3
We implement an electron avalanche photodiode (e-APD) in the MIRC-X instrument, upgrade of the 6-telescope near-infrared imager MIRC, at the CHARA array. This technology should imp…
