In the last decades, a very important breakthrough has been brought about in the elementary particle physics by the discovery of the phenomenon of the neutrino oscillations, which has shown neutrino properties beyond the Standard Model. But a full understanding of the various aspects of the neutrino oscillations is far to be achieved. In this paper the

Hidden No More: Spotlight on Tidal Disruption Events in Active Galactic Nuclei
ABSTRACT Tidal disruption events (TDEs) are typically discovered in previously quiescent galaxies. However, earlier studies have revealed a handful of TDEs occurring in pre‐existing active galactic nuclei (AGN). We discuss AT2019aalc, a promising TDE candidate in an AGN, and compare it to similar sources.

Methods to estimate marine functional connectivity: A primer
Abstract Organism movement is a key process in the transfer of individuals, genes, functional traits, matter, and energy among habitat patches, at sea and across the land–sea interface. The resulting fluxes, collectively termed marine functional connectivity (MFC), underpin planetary health and an array of ecosystem services.

This is a review for Reports of Progress in Physics. After an introduction we start by explaining the different neutrino masses corresponding to different types of neutrinos, Dirac or Majorana, in section 2. In section 3 we discuss the main elementary particle models for neutrino masses and their distinctive phenomenological consequences.

Investigating the Impact of Rocket Exhaust on Ionospheric Disturbances
Abstract The study of chemical releases into the ionosphere is crucial for understanding ionospheric dynamics and managing space environmental effects. In this work, we investigate the impact of rocket exhaust emissions, particularly CO2 and H2O, on electron density in the ionosphere.

Supermassive black hole (BH) mergers with spin-flips accelerate energetic particles through their relativistic precessing jets, producing high-energy neutrinos and finally gravitational waves (GWs).

GOES‐R Series X‐Ray Sensor (XRS): 2. On‐Orbit Measurements and Calibrations
Abstract An X‐Ray Sensor (XRS) has been onboard each of the National Oceanic and Atmospheric Administration (NOAA) Geostationary Operational Environmental Satellites (GOES) since 1975. XRS measures full‐disk soft X‐ray irradiance in two wavelength bands, 0.05–0.4 nm and 0.1–0.8 nm.

A Possible Solution to the Mystery of the ANITA Anomalous Events
In 2006 and 2014, the Antarctic Impulsive Transient Antenna (ANITA), a balloon‐borne radio observatory flying over Antarctica, detected two strange upward‐going radio pulse events that have not yet been explained by our current understanding of physics.

Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

PHENOMENOLOGY OF NEUTRINO OSCILLATIONS AT A NEUTRINO FACTORY [PDF]
It is shown in the three flavor framework that neutrino factories enable us to measure some of the oscillation parameters, such as the sign of $Δm_{32}^2$, $θ_{13}$, $δ$. Some efforts are made to determine the parameters (the muon energy and the neutrino path length) of a neutrino factory to optimize the signals.
