A 4200-hour HyperFlash and ÉCLAT campaign on the hyperactive FRB 20240114A: constraining energetics with the most brilliant bursts

Abstract Hyperactive repeaters provide a unique window into the evolving environments and energy budgets of fast radio burst (FRB) sources, though they may not be representative of the FRB population in general. High-cadence observations are key to capturing the rarest and most e...

Astrophysical Parameters of 5056 Open Star Clusters from Bayesian Nested Sampling with PARSEC Isochrones

Abstract We present a homogeneous catalogue of ages, metallicities, distances, and reddenings for 5 056 open clusters in the Unified Cluster Catalogue (UCC), derived uniformly from Gaia Data Release 3 (DR3) colour–magnitude diagrams via Bayesian nested sampling with PARSEC isochr...

Statistical methods for partitioning ribbon and globally-distributed flux using data from the Interstellar Boundary Explorer

NASA’s Interstellar Boundary Explorer (IBEX) satellite collects data on energetic neutral atoms (ENAs) that can provide insight into the heliosphere boundary between our solar system and interstellar space. Using these data, scientists can construct maps of the ENA intensities (o...

Options for Compression of radio interferometry data: lossy compression of visibilities and lossless compression of uv-visibility grids for the MHONGOOSE survey

Abstract Next generation radio astronomy telescopes are challenging existing data reduction paradigms. With ever more antennas, larger bandwidths, and sometimes multiple primary beams, they often generate more observed data products than can readily be stored long-term. Thus, dat...

Piezo1 footprint nanoarchitecture: from individual channels to collective behaviour and from outward to inward curvature

Piezo1 acts as a key architect of the cell membrane, generating a curved nanodome that extends beyond the protein trimer itself. Although Piezo1 intrinsically favours an outward (convex) membrane footprint, recent high-resolution studies have revealed that clustered channels can...

Discovery of a Compact Hub-Filament System in G286.21+0.17 with JWST and ALMA: Insights into Protocluster Formation and Competitive Accretion

Abstract We present a multi-wavelength study of the massive protocluster G286.21+0.17 (G286) using JWST near-infrared (NIR) imaging and ALMA H13CO+(1–0) observations. The JWST images uncover a compact (∼0.5 pc) hub-filament system (HFS), comprising a dense central hub connected b...

Gas absorption of soft X-rays strongly impacts the redshift distribution of dark Fast X-ray Transients

Abstract The progenitors of many Fast X-ray Transients (FXTs) and those of γ-ray bursts (GRBs) are strongly linked. Given that ”dark” GRBs are typically found to be events suffering from enhanced extinction in the host galaxy, we investigate the nature of ”dark” FXTs. However, un...

Graphene-based Photodetector with Engineered Hot-Carrier Cooling Dynamics

Abstract Graphene has emerged as a promising material for integration into silicon photonics, owing to its ultrafast and broadband photoresponse without the need for an external bias voltage. This photoresponse relies on the photo-thermoelectric effect created by hot carriers. A...

A semi-analytical Ring-Arc model for Plutino perturbations

Abstract Neptune’s 2:3 mean motion resonance induces an asymmetric spatial distribution of Plutinos. We previously proposed a 9000-point-mass arc model that successfully captures the resulting influence on planetary ephemerides. However, integrating thousands of point masses invo...

Joint XMM-Newton and NuSTAR Observations of Type I X-ray Bursts from the Dipping Low-Mass X-ray Binary 4U 1323–62

Abstract In this study, we report partly simultaneous XMM-Newton and NuSTAR observations of the bursting, dipping low mass X-ray binary, 4U 1323–62 obtained in 2024. 4U 1323–62 is one of the well-known persistent bursters, with bursts occurring roughly every three hours. It is al...

Linking solar magnetism, extreme solar particle events and stellar superflares

The magnetic field of the Sun drives a wide range of eruptive phenomena, from small-scale nanoflares to large flares and coronal mass ejections. While direct observations of solar activity cover only the past few decades, indirect evidence indicates that the Sun can occasionally...

How to train your slop cannon: A short guide to using large language models for research in the natural sciences

Large Language Models are transforming mathematics and the physical sciences, allowing scientists to explore ideas quickly and raise their sights to grand challenges. But they also produce plausible but wrong text at industrial scale. Staying afloat in this torrent of slop requir...

Dust Substructures and Line Perturbations driven by a Forming Planet in J16120

Abstract Hints of planet formation have been independently reported within the gap of the disc around 2MASS J16120668-301027 from millimetre continuum, infrared, and Hα observations. In this work, we present new evidence for ongoing planet formation based on Atacama Large Millime...

Kinematic relationship between solar extreme ultraviolet waves and type II metric radio bursts

Solar extreme-ultraviolet (EUV) waves are large-scale disturbances that manifest as bright wavefronts, often during coronal mass ejections (CMEs). According to the magnetic field line stretching model, this phenomenon comprises two components: a fast-mode CME piston-driven shock...

Comparative Analysis of Ion and Electron Contributions to Ionospheric Ionization at Auroral and Subauroral Latitudes

Abstract Electron and proton precipitation into the nightside ionosphere is a key process in magnetosphere–ionosphere coupling. Although auroral electron precipitation at –10 keV is traditionally considered the main driver of auroral emissions, recent studies show that keV electr...

QUANTUM RESOLUTION TO-THE STATISTICAL-THERMODYNAMIC IN THE EXISTENCE OF LIFE

[Note: Translated with the assistance of Artificial Intelligence. Version 3 provides the full English translation of Version 2, which was originally written in Indonesian] This theoretical paper proposes a resolution to the apparent contradiction between classical statistical pro...

The Total and Polarized Radio Emission from the Innermost Jets of a High-Redshift Quasar and a Candidate at Parsec-Scale Resolution

High-frequency very long baseline interferometry (VLBI) polarimetry probes synchrotron-emitting plasma closer to the central engines of radio-loud active galactic nuclei (AGNs), but observations above 43 GHz are technically demanding. We present 22-GHz European VLBI Network obser...
