I will discuss the state and of high-energy and multi-messenger astrophysics, and consider the exciting prospects for this field moving forward.
On June 29, 2023, the five regional PTAs, including the Indian pulsar timing array (InPTA) announced the evidence for the presence of gravitational waves (GWs) in the nano-Hz frequency regime. This was the first evidence for GWs outside the frequency range of those detected by the ground-based observatories. Currently the international PTA community is gearing towards the analysis of the data...
The Large Hadron Collider beauty (LHCb) experiment has played a pivotal role in advancing our understanding of particle physics, particularly in the study of heavy quarks and their interactions. This talk will present the latest highlights from LHCb, including groundbreaking results in the areas of flavor physics, CP violation, and rare decays. We will discuss recent measurements that...
Whether the neutrino is a Majorana particle, i.e., whether it is its own antiparticle, remains an important open problem in modern physics. The observation of the hypothesized second order weak decay, Neutrinoless Double Beta Decay (0$\nu\beta\beta$) would conclusively establish the Majorana nature of neutrinos. It would also demonstrate lepton number violation and could provide insight into...
The IceCube Neutrino Observatory is a flagship cubic-kilometer neutrino detector made up of transparent, natural Antarctic ice at the South Pole, which is instrumented with digital optical modules to detect Cherenkov light emitted during interactions of neutrinos with energies spanning more than 10 orders of magnitude. It is a unique multidisciplinary facility that has produced several...
How can we decide which cosmological model is the most probable? In a Bayesian approach to statistics, this question can be readily answered using the framework of Bayesian model selection: namely by calculating a model's evidence. However, the numerical evaluation of the evidence can be a numerically difficult task.
I will introduce a new, efficient machine-learning approach to this...
After a brief introduction to neutrino electromagnetic properties, I will focus on the correlation between neutrino magnetic moment and neutrino mass mechanism. Then, I will discuss that the models that induce large neutrino magnetic moments while maintaining their small masses naturally also predict observable shifts in the charged lepton anomalous magnetic moment by showing that the...
Neutrinos are known to have non-zero masses, as shown by oscillation observations, but their absolute mass scale remains unknown. Observational cosmology and neutrinoless double beta decay experiments derive sub-eV upper limits. Complementing these efforts with a model-independent approach based on beta-decay kinematics, the Karlsruhe Tritium Neutrino (KATRIN) experiment provides the most...
We propose a scenario where a heavy RHN DM can be produced by a thermal effect undergoing a resonance at high temperature in the early Universe
If produced in the early Universe with an initial mass of ∼ 10^15 g, PBHs are expected to evaporate at the present time producing sizable fluxes of particles in their last instants. These “exploding” black holes will emit bursts of Standard Model particles as well as new degrees of freedom, if present. We explore the possibility that HNLs mixing with the active neutrinos are emitted in the...
The GRAPES-3 experiment setup at an altitude of 2200 m in Ooty, India, employs a dense array of plastic scintillator detectors complemented with a large-area tracking muon detector. It is designed to observe shower particles which mostly include gamma rays, electrons and muons produced by interactions of primary cosmic rays and gamma rays in Earth’s atmosphere. Recently, GRAPES-3 successfully...
The coupling of axion and axion-like particles (ALPs) to two photons leads to radiative decays of axion dark matter and axion-photon conversion in an external magnetic field. We discuss two methods to search for these signals exploiting astrophysical data. The first is based on MUSE spectroscopic optical observations of a sample of five classical and ultra-faint dwarf spheroidal galaxies.
We...
I will take a brief overview of the recent developments in the field of strongly interacting dark matter. I will discuss new ways to generate dark matter relic density as well as discuss associated detection strategies.
The TEXONO collaboration has been producing world-class results related to reactor neutrinos and dark matter for more than two decades. In this conference, I will discuss the results obtained by the TEXONO experiment based on neutrino-nucleus coherent scattering and will discuss in detail the current status and future plans of the collaboration.
I identify the maximum cross sections probed by single-scatter ``WIMP'' searches in dark matter direct detection. Due to Poisson fluctuations in scatter multiplicity, these ceilings scale logarithmically with mass for heavy dark matter and often lie in regions probed by multiscatter searches. I will present a generalized formula for single-scatter event rates, and use it to recast WIMP...
The Pierre Auger Observatory, the world’s largest cosmic-ray detector, continues to make significant advances in the study of ultra-high-energy cosmic rays (UHECRs). By utilizing a hybrid detection system of surface and fluorescence detectors, the Observatory has made substantial contributions to our understanding of UHECR origins, composition, and energy spectrum, offering a consistent...
