Fast MHD oscillations of a 3-dimensional prominence fibril
High-resolution observations of quiescent filaments point out that their fine structure is made of small-scale threads or fibrils. These fibrils can be...
Fast quasi-periodic oscillations in the eclipsing polar VV Puppis from VLT and XMM-Newton observations
We present high time resolution optical photometric data of the polar VV Puppis obtained simultaneously in three filters (u', HeII λ4686, r') with the ULTRACAM...
Fast simulation mapping: From standard to modified gravity cosmologies using the bias assignment method
Context. We assess the effectiveness of a non-parametric bias model in generating mock halo catalogues for modified gravity (MG) cosmologies, relying on the...
Fast X-ray/IR observations of the black hole transient Swift J1753.5–0127: From an IR lead to a very long jet lag
We report two epochs of simultaneous near-infrared (IR) and X-ray observations of the low-mass X-ray binary black hole candidate Swift J1753.5–0127 with a...
Feature-rich transmission spectrum for WASP-127b. Cloud-free skies for the puffiest known super-Neptune?
Context. WASP-127b is a planet with one of the lowest densities discovered to date. With a sub-Saturn mass (Mp = 0.18 ± 0.02 MJ) and super-Jupiter radius (Rp =...
Featureless transmission spectra of 12 giant exoplanets observed by GTC/OSIRIS
Context. Exoplanet atmospheres are the key to understanding the nature of exoplanets. To this end, transit spectrophotometry provides us opportunities to...
Feeding and feedback processes in the Spiderweb proto-intracluster medium
Context. We present a detailed analysis of the thermal, diffuse emission of the proto-intracluster medium (proto-ICM) detected in the halo of the Spiderweb...
Feeding the spider with carbon. [CII] emission from the circumgalactic medium and active galactic nucleus
We present the detection of [CII] 158 μm emission from the Spiderweb galaxy at z = 2.1612 using the Atacama Pathfinder EXperiment (APEX). The line profile...
