Results of the follow-up of ANTARES neutrino alerts
High-energy neutrinos could be produced in the interaction of charged cosmic rays with matter or radiation surrounding astrophysical sources. To look for...
Resurfacing processes constrained by crater distribution on Ryugu
Understanding the geological modification processes on asteroids is fundamental for elucidating their surface evolution. Images of small asteroids from...
Resurfacing processes on asteroid (162173) Ryugu caused by an artificial impact of Hayabusa2's Small Carry-on Impactor
The resurfacing process on Ryugu accompanying the artificial impact crater formation by Hayabusa2's Small Carry-on Impactor (SCI) was studied by comparing pre-...
Retrieval of solar magnetic fields from high-spatial resolution filtergraph data: the Imaging Magnetograph eXperiment (IMaX)
Context. The design of modern instruments does not only imply thorough studies of instrumental effects but also a good understanding of the scientific analysis...
Retrieval of the physical parameters of galaxies from WEAVE-StePS-like data using machine learning
Context. The William Herschel Telescope Enhanced Area Velocity Explorer (WEAVE) is a new, massively multiplexing spectrograph that allows us to collect about...
Retrieval Survey of Metals in Six Ultrahot Jupiters: Trends in Chemistry, Rain-out, Ionization, and Atmospheric Dynamics
Ground-based high-resolution spectroscopy (HRS) has detected numerous chemical species and atmospheric dynamics in exoplanets, most notably ultrahot Jupiters...
Retrieving day- and nightside atmospheric properties of the ultra-hot Jupiter TOI-2109b: Detection of Fe and CO emission lines and evidence for inefficient heat transport
The ultra-hot Jupiter (UHJ) TOI-2109b marks the lower edge of the equilibrium temperature gap between 3500 and 4500 K, an unexplored thermal regime that...
Retrieving the transmission spectrum of HD 209458b using CHOCOLATE: a new chromatic Doppler tomography technique
Multiband photometric transit observations or low-resolution spectroscopy (spectro-photometry) are normally used to retrieve the broadband transmission spectra...
Retuning radio astronomy for axion dark matter with neutron stars
A model is constructed to predict the emission originating from axion-to-photon conversion in the strongly magnetized ultrarelativistic plasma of neutron stars...
