Euclid preparation: XX. The Complete Calibration of the Color-Redshift Relation survey: LBT observations and data release
Euclid Collaboration, R. Saglia, S. De Nicola +183
The Complete Calibration of the Color-Redshift Relation survey (C3R2) is a spectroscopic programme designed to empirically calibrate the galaxy color-redshift relation to the Eucli…
On-sky results for the novel integrated micro-lens ring tip-tilt sensor
Philipp Hottinger, Robert J. Harris, Jonathan Crass +16
We present the first on-sky results of the micro-lens ring tip-tilt (MLR-TT) sensor. This sensor utilizes a 3D printed micro-lens ring feeding six multi-mode fibers to sense misali…
A triple star in disarray -- Multi-epoch observations of T Tauri with VLT-SPHERE and LBT-LUCI
M. Kasper, K. K. R. Santhakumari, T. M. Herbst +24
T Tauri remains an enigmatic triple star for which neither the evolutionary state of the stars themselves, nor the geometry of the complex outflow system is completely understood.…
3C 294 revisited: Deep Large Binocular Telescope AO NIR images and optical spectroscopy
J. Heidt, A. Quirrenbach, N. Hoyer +11
Context. High redshift radio galaxies are among the most massive galaxies at their redshift, are often found at the center of protoclusters of galaxies, and are expected to evolve…
Polarization angle swings in blazars: The case of 3C 279
S. Kiehlmann, T. Savolainen, S. G. Jorstad +61
Over the past few years, several occasions of large, continuous rotations of the electric vector position angle (EVPA) of linearly polarized optical emission from blazars have been…
Analyzing polarization swings in 3C 279
S. Kiehlmann, T. Savolainen, S. G. Jorstad +53
Quasar 3C 279 is known to exhibit episodes of optical polarization angle rotation. We present new, well-sampled optical polarization data for 3C 279 and introduce a method to disti…
