Microwave and radio observations exhibit some interesting features in the Galactic plane. One of those is the Fan region which is an extended region located in the Perseus arm at a distance of 500 pc. Fan region has highly polarized emission from several MHz up to 353 GHz, which is ascribed to synchrotron but nowadays is largely unexplained. Here

With a mass, radius, and mean density similar to Earth's, the rocky planet GJ 1132 b is the first truly small planet for which an atmosphere detection was proposed. If confirmed, ultra-reduced magma outgassing is the only mechanism capable of producing HCN and H 2O in large enough quantities to match the Hubble Space Telescope observations. The

Cosmological hydrodynamical simulations provide valuable insights on galaxy evolution when coupled with observational data. Comparisons with real galaxies are typically performed via scaling relations of the observables. Here, we follow an alternative approach based on the spectral covariance in a model-independent way. We build upon previous work

We present the Flagship galaxy mock, a simulated catalogue of billions of galaxies designed to support the scientific exploitation of the Euclid mission. Euclid is a medium-class mission of the European Space Agency optimised to determine the properties of dark matter and dark energy on the largest scales of the Universe. It probes structure

We investigated the ability of the Euclid telescope to detect galaxy-scale gravitational lenses. To do so, we performed a systematic visual inspection of the 0.7 deg 2 Euclid Early Release Observations data towards the Perseus cluster using both the high-resolution I E band and the lower-resolution Y E , J E, and H E bands. Each extended source

The near-infrared calibration unit (NI-CU) on board Euclid's Near-Infrared Spectrometer and Photometer (NISP) is the first astronomical calibration lamp based on light-emitting diodes (LEDs) to be operated in space. Euclid is a mission in ESA's Cosmic Vision 2015–2025 framework to explore the dark universe and provide a next-level characterisation
