The dark sector offers a compelling theoretical framework for addressing the nature of dark matter while potentially solving other fundamental problems in physics. This review focuses on light dark-flavored sector models, in which the flavor structure of the interactions with the Standard Model is nontrivial and distinguishes among different

We present the first results from ATLAS-Teide, the new unit of the Asteroid Terrestrial-impact Last Alert System (ATLAS) installed by the Instituto de Astrofísica de Canarias (IAC) at the Teide Observatory (Tenerife, Spain) in January 2025. ATLAS-Teide is part of the IAC's "Strategic Plan of the Canarian Observatories," supported by projects

The solar system small bodies community, having a dedicated interest in the planetary defense science opportunity presented by the exceedingly rare natural event of the large (340-meter) asteroid Apophis safely passing within 32,000 km of Earth on 2029 April 13, held a two-day Workshop at the University of Tokyo, April 9-10, 2025. This "Apophis T-4

The nature of the minute-to-hour-long fast X-ray transients localized by telescopes such as Chandra, Swift and XMM-Newton remains mysterious, with numerous models suggested for the events. Here we report multi-wavelength observations of EP240315a, a 1,600-s-long transient detected by the Einstein Probe, showing it to have a redshift of z = 4.859

Context. The mechanism behind the heating of the solar chromosphere remains unclear. Friction between neutrals and charges is expected to contribute to plasma heating in a partially ionised plasma (PIP). Aims. We aim to study the efficiency of the frictional heating mechanism in partially ionised plasmas by comparing a single-fluid model (1F) using

The Large Magellanic Cloud (LMC) is a Milky Way (MW) satellite that is massive enough to gravitationally attract the MW disc and inner halo, causing significant motion of the inner MW with respect to the outer halo. In this work, we probe this interaction by constructing a sample of 9866 blue horizontal branch (BHB) stars with radial velocities
