We propose a focal-plane wavefront sensor (FPWFS) based on a short multimode fiber (MMF). By coupling the aberrated focal-plane field into an MMF of length 1 cm, we preserve modal interference over a 10 nm bandwidth at near-infrared wavelengths, but broader bandwidths could be achieved by appropriately tuning the fiber length. The resulting output

We introduce SYNFERENCE, a new flexible Python framework for galaxy spectral energy distribution (SED) fitting using simulation-based inference (SBI). SYNFERENCE leverages the SYNTHESIZER package for flexible forward-modelling of galaxy SEDs and integrates the LTU-ILI package to ensure best practices in model training and validation. In this work

TON 0599 (z = 0.7247) belongs to the few flat spectrum radio quasars (FSRQs) detected in the very high energy (VHE, $E > 100$ GeV) gamma-ray band. Its redshift makes it currently one of the farthest VHE gamma-ray sources. It was detected for the first time with the MAGIC telescopes on 2017 December 15, and observed until December 29. The flux

IGR J17091 − 3624 is a distinctive black hole X-ray binary exhibiting exotic variability, including complex 'heartbeat' oscillations in its X-ray light curves, similar to those observed in GRS 1915 + 105, a system renowned for its structured, rapid X-ray variability but heavily obscured at optical wavelengths. In contrast, IGR J17091 − 3624 is less

The ExoClock project is an open platform aiming to monitor exoplanets by integrating observations from space- and ground-based telescopes. This study presents an updated catalog of 620 exoplanet ephemerides, integrating 30,000 measurements from ground-based telescopes (the ExoClock network), literature, and space telescopes (Kepler, K2 and TESS)

Context. Transmission spectroscopy serves as a valuable tool for probing atmospheric absorption features in the terminator regions of exoplanets. Stellar surface heterogeneity can introduce wavelength-dependent contamination that complicates the interpretation of planetary spectra. Aims. We aim to investigate the atmosphere of the warm sub-Saturn
