NAIR-APREXIS: Enabling photonics-based instruments for long-baseline interferometry and integral-field spectroscopy
L. Labadie, R. J. Harris, K. Madhav +14
The NAIR project -- Novel Astronomical Instrumentation based on photonic light Reformatting -- aims at advancing photonic technologies for infrared long-baseline interferometry and…
On-sky demonstration of dual-field interferometry at the CHARA Array
Narsireddy Anugu, John D. Monnier, Douglas R. Gies +10
Dual-field interferometry uses a bright reference star for real-time fringe tracking, allowing a second beam combiner to record long coherent integrations on a fainter off-axis sci…
CHARA Array Delay Lines: Upgrades, Performance and Future Directions
Narsireddy Anugu, Nils H. Turner, Theo A. ten Brummelaar +12
Long baseline optical and infrared interferometric arrays achieve high angular resolution and enable detailed astrophysical measurements. Interferometers have enabled observations…
The CHARA Array Polarization Model and Prospects for Spectropolarimetry
Linling Shuai, John D. Monnier, Benjamin R. Setterholm +5
Polarimetric data provide key insights into infrared emission mechanisms in the inner disks of YSOs and the details of dust formation around AGB stars. While polarization measureme…
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) i…
CHARA/Silmaril Instrument Software and Data Reduction Pipeline: Characterization of the Instrument in the Lab and On-Sky
Narsireddy Anugu, Theo A. ten brummelaar, Cyprien Lanthermann +9
The newly installed Silmaril beam combiner at the CHARA array is designed to observe previously inaccessible faint targets, including Active Galactic Nuclei and T-Tauri Young Stell…
