High-angular resolution and high-contrast VLTI observations from Y to L band with the Asgard instrumental suite
Marc-Antoine Martinod, Denis Defrère, Michael Ireland +17
The Very Large Telescope Interferometer is one of the most proficient observatories in the world for high angular resolution. Since its first observations, it has hosted several in…
Spectrograph design for the Asgard/BIFROST spectro-interferometric instrument for the VLTI
Sorabh Chhabra, Michele Frangiamore, Stefan Kraus +4
The BIFROST instrument will be the first VLTI instrument optimised for high spectral resolution up to R=25,000 and operate between 1.05 and 1.7 m. A key component of the instrum…
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)…
Crosstalk in image plane beam combination for optical interferometers
Daniel J. Mortimer, David F. Buscher
Image plane beam combination in optical interferometers multiplexes the interference fringes from multiple baselines onto a single detector. The beams of starlight are arranged in…
Reaching Diverse Groups in Long-Term Astronomy Public Engagement Efforts
Melanie Archipley, Hannah S. Dalgleish, Eva-Maria Ahrer +1
Professional astronomy is historically not an environment of diverse identities. In recognizing that public outreach efforts affect career outcomes for young people, it is importan…
3D shape of Orion A from Gaia DR2
Josefa E. Grossschedl, Joao Alves, Stefan Meingast +16
We use the DR2 distances of about 700 mid-infrared selected young stellar objects in the benchmark giant molecular cloud Orion A to infer its 3D shape and orientati…
