GROND - a 7-channel imager
J. Greiner, W. Bornemann, C. Clemens +19
We describe the construction of GROND, a 7-channel imager, primarily designed for rapid observations of gamma-ray burst afterglows. It allows simultaneous imaging in the Sloan g'r'…
The Enhanced Resolution Imager and Spectrograph for the VLT
R. Davies, O. Absil, G. Agapito +81
ERIS, the Enhanced Resolution Imager and Spectrograph, is an instrument that both extends and enhances the fundamental diffraction limited imaging and spectroscopy capability for t…
Compatibility of neutron star masses and hyperon coupling constants
H. Huber, M. K. Weigel, F. Weber
It is shown that the modern equations of state for neutron star matter based on microscopic calculations of symmetric and asymmetric nuclear matter are compatible with the lower bo…
The MICADO first light imager for the ELT: eliminating vibrations and excessive earthquake-loads on specific subsystems
H. Nicklas, S. Schäfer, H. Anwand-Heerwart +3
Ensuring earthquake resilience is paramount for the upcoming Extremely Large Telescope (ELT). Instruments positioned on the ELT's Nasmyth platform are anticipated to endure substan…
The GRAVITY metrology system: modeling a metrology in optical fibers
N. Blind, H. Huber, F. Eisenhauer +20
GRAVITY is the second generation VLT Interferometer (VLTI) instrument for high-precision narrow-angle astrometry and phase-referenced interferometric imaging. The laser metrology s…
Making SPIFFI SPIFFIER: Upgrade of the SPIFFI instrument for use in ERIS and performance analysis from re-commissioning
E. M. George, D. Gräff, H. Feuchtgruber +15
SPIFFI is an AO-fed integral field spectrograph operating as part of SINFONI on the VLT, which will be upgraded and reused as SPIFFIER in the new VLT instrument ERIS. In January 20…
