The background galaxies in Euclid Early Release Observation images of the Perseus cluster make up a remarkable sample for the combination of a 0.57 deg 2 area, 25.3 and 23.2 AB mag depth, and angular resolutions in the optical and near-infrared bands of 0 ⋅ ''1 and 0 ⋅ ''3, respectively. As part of the effort towards characterising the history of

The Euclid Ecliptic Survey was conducted during the calibration phase of the mission, from 23 to 31 December 2023, as a campaign to study Solar System objects. We used data from this survey to analyse more than 23 000 appeareances of 2321 known asteroids. Due to their high apparent angular motion relative to the background stars (5─60″ h −1), these

In this work, we present early emission data analysis of the tidal disruption event TDE 2025aarm, including optical, UV, and X-ray data. At a redshift of z = 0.01368, TDE 2025aarm is the second closest TDE ever discovered, offering a valuable opportunity to study such phenomena in great detail. We observed TDE 2025aarm in the optical with the

Context. Hot subdwarf binaries with white dwarf companions with orbital periods of less than two hours are progenitor candidates for massive single white dwarfs as well as a variety of thermonuclear explosions. Aims. Our aim is to determine the binary properties of the hot subdwarf ─ white dwarf system ZTF J000742.62+480414.51, model its future

The James Webb Space Telescope (JWST) has revolutionized the characterization of exoplanetary atmospheres, offering unprecedented sensitivity to probe their chemical and physical properties. Recently, a growing trend has emerged to obtain atmospheric information directly from pixel-level planetary spectra. In this work, we reanalyzed the WASP-18 b

We report the detection of a set of new near-infrared emission features between 3.5 and 5.2 μm in JWST/NIRSpec observations of Tc 1, the planetary nebula known for displaying the cleanest and most prominent mid-infrared cosmic fullerene spectrum. These broad features share the same spatial distribution as the well-known C 60 and C 70 mid-infrared
