Ion Irradiation of GridPix Detector at Bonn Isochronous Cyclotron
Vladislavs Plesanovs, Hemanth Manikantan, Dennis Sauerland +6
The potential successor of the IXPE --- the EXPO or Enhanced X-ray Polarimetry Observatory will have a new X-ray polarimeter based on GridPix technology. To certify this detector f…
Controlled ion-ion interactions and cavity-enhanced emission of a coherent dinuclear Eu complex
Evgenij Vasilenko, Vishnu Unni Chorakkunnath, Barbora Brachnakova +4
Molecular rare-earth-ion complexes offer unique opportunities for quantum technologies by combining the intrinsic coherence properties of rare-earth ions with chemically tunable mo…
TOI-2322: two transiting rocky planets close to the stellar rotation period and its first harmonic
M. J. Hobson, A. Suárez Mascareño, C. Lovis +42
Context. Active regions on the stellar surface can induce quasi-periodic radial velocity (RV) variations that can mimic planets and mask true planetary signals. These spurious sign…
Blind search for activity-sensitive lines in the near-infrared using HARPS and NIRPS observations of Proxima and Gl 581
João Gomes da Silva, Elisa Delgado-Mena, Nuno C. Santos +145
Stellar activity variability is one of the main obstacles to the detection of Earth-like planets using the RV method. The aim of this work is to measure the effect of activity in t…
