Ultra-High Energy (UHE, >0.1PeV) gamma-ray Astronomy is rapidly developing into an important branch of the gamma-ray astronomy with a lot of surprising discoveries. In this presentation, I will briefly review the main results of LHAASO, HAWC and ASgamma in recent years and discuss their physical implications.

Here we demonstrate turbulent magnetic reconnection in laser-generated plasmas created when irradiating solid targets. Turbulence is generated by strongly driven magnetic reconnection, which fragments the current sheet, and we also observe the formation of multiple magnetic islands and flux-tubes. Our findings reproduce key features of solar fare observations. Supported by kinetic simulations,...

The TeV afterglow of the BOAT GRB 221009A was interpreted as arising from a narrow jet, while the radio-to-X-ray afterglows were interpreted as arising from a wide structured jet. However, there is no model explaining the TeV and lower-energy multiwavelength afterglows simultaneously. We here investigate a two-component jet model, including a narrow uniform core with a wide structured wing, to...

While neutrino flavor transformation in low-density environments is the target of many experimental and observational campaigns, the rich phenomenology of neutrino flavor transformation in neutrino-dense environments like core-collapse supernovae and neutron star mergers is presently the object of intense theoretical efforts. These phenomena have the potential to alter the course of explosion,...

We would like to propose a new astrophysical method to constrain still unknown neutrino mass hierarchy in terms of the flavor conversions at high-density in supernovae [1]. There is a growing consensus in recent multi-messenger astronomy that the explosions of single massive stars, i.e. magneto-hydrodynamic jet supernova and collapsar, dominate the heavy-element enrichment over the entire...

MeV gamma rays are indispensable probes for high-energy astrophysics research, providing unique information to help address frontiers, such as the origin of cosmic rays, dark matter, the radiation mechanisms of compact objects, and etc. In particular, MeV range is the domain of nuclear gamma-ray lines that can provide a direct probe of the nuclear processes (such as supernovae,...

As we move towards the multi-telescope era of neutrino astronomy, it is i critical to develop collaborative approaches that ensure maximal scientific output. One facet of fulfilling this need is common tools for simulation and data analysis across detectors. In this talk, I will present Prometheus, an open-source framework for simulating neutrino interactions in neutrino telescopes. I will...

The TRopIcal DEep-sea Neutrino Telescope (TRIDENT) aims to deploy optical detection modules within ~8 km3 of seawater, approximately 3.5 km deep in the South China Sea. Following the discovery of diffuse astrophysical neutrinos by the IceCube Neutrino Observatory, next-generation telescopes with increased size and improved performance expect to be on the verge of multiple discoveries....

The JUNO experiment is a neutrino experiment based on a 20-kiloton liquid scintillator detector, which is expected to observe various types of neutrinos, including reactor, atmosphere, solar, geo, and supernova neutrinos. The detector consists of a 35.4-meter-diameter acrylic vessel filled with liquid scintillator, supported by a stainless steel structure, and equipped with over 40,000...

Neutral current π⁰ (NCπ⁰) events are a major background for ν$_e$ signal events in T2K neutrino oscillation measurements. These events, characterised by two photons from π⁰ decay, can mimic the detector response of electrons in Super-Kamiokande (Super-K). Previously, there were no dedicated samples to effectively constrain this NCπ⁰ background. To address this, events reconstructed with two...

In this talk I will review how current cosmological probes can help us to constrain the properties of neutrinos, in particular their absolute mass scale. I will discuss the results from the Planck observations of the Cosmic Microwave Background, present recent updates that take into account Baryon Acoustic Oscillation bounds from DESI and show how degeneracies with other cosmological...

Dark photons have emerged as promising candidates for dark matter, and their search is a top priority in particle physics, astrophysics, and cosmology. We report the first use of a tunable niobium superconducting radio-frequency cavity for a scan search of dark photon dark matter with innovative data analysis techniques. We mechanically adjusted the resonant frequency of a cavity submerged in...

We propose here a set of new methods to directly detect light mass dark matter through its scattering with abundant atmospheric muons or accelerator beams. Firstly, we plan to use the free cosmic-ray muons interacting with dark matter in a volume surrounded by tracking detectors, to trace possible interaction between dark matter and muons. Secondly, we will interface our device with domestic...
