1 Yemilab status focused on the COSINE and AMoRE experiments

In September 2022, Yemilab, a new underground laboratory in Korea, was completed in Jeongseon, Gangwon Province. Located 1,000 meters below ground, it offers an exclusive experimental area of 3,000 m². Currently, preparations are underway for the AMoRE-II experiment, which seeks to explore neutrinoless double beta decay, and for the COSINE-100 upgrade (COSINE-100U), a direct dark matter detection experiment. Since 2022, Yemilab’s infrastructure has been enhanced to support rare event search experiments. In this presentation, I will discuss the physics achievements of the AMoRE and COSINE-100 experiments conducted at the Yangyang Underground Laboratory and provide an update on the current progress of Yemilab’s installation and experimental setup.

6 Observations of Ultra-High Energy Cosmic Rays and Radio Galaxies as their Origin

Ultra-high-energy cosmic rays (UHECRs) are currently being observed in two leading experiments, the Pierre Auger Observatory (PAO) in the southern hemisphere and the Telescope Array (TA) in the northern hemisphere. Despite similar experimental methodologies, the two experiments report discrepancies in their observations, particularly at energies above a few tens EeV. Specifically, the particle flux observed by PAO is lower than that by TA, and the mass composition appears to be heavier at PAO than at TA. Radio galaxies (RGs) are the most promising sources for UHECRs, and we investigated the RG origin of UHECRs through relativistic hydrodynamic simulations of FR I/II type jets and Monte Carlo simulations of particle transport and acceleration. While diffusive shock acceleration is the dominant process at energies below EeV, relativistic shear acceleration at the jet-cocoon interface is more important at lower energies. The resulting energy spectrum is best described by a double power law with an ``extended'' exponential cutoff. We then simulated the propagation of UHECRs from RGs both in the local universe and at cosmological distances, through the intergalactic space to Earth. Our results suggest that UHECRs in the northern hemisphere exhibit a higher flux and a lighter composition at the highest energies than in the southern hemisphere if they are originated from RGs. We attribute this to the fact that Virgo A has a jet with a higher Lorentz factor compared to Centaurus A and Fornax A. These findings offer a potential explanation for the discrepancies in UHECR flux and mass composition observed by the PAO and TA experiments.

9 Search for QCD axions in CAPP

Speaker: Dr 성우 윤 (IBS-CAPP)

10 Ultralight Cold Dark Matter

Ultralight cold dark matter, also known as fuzzy dark matter or ultralight axion, is a scalar field with an extremely light mass of approximately 10^{-22} eV. In this model, dark matter in galactic halos exists in a Bose-Einstein condensate state and is described by a macroscopic wave function with a de Broglie wavelength on the order of a kiloparsec. This approach offers potential solutions to small-scale issues in the cold dark matter (CDM) paradigm and may help explain several cosmological mysteries, such as galaxy sizes and masses, the satellite galaxy plane, the Hubble tension, and the final parsec problem. If the scalar field attains a field value at the grand unified theory (GUT) scale, it can account for the observed dark matter density. In models with interactions, the field could be a pseudo Nambu-Goldstone boson associated with the GUT phase transition, which may also yield insights into the mass of neutrinos and the electroweak interaction scale.

11 Multi-messenger Astrophysics of Extragalactic TeV-PeV Neutrino Emitters

The detection of TeV-PeV neutrinos by the IceCube Neutrino Observatory, alongside KM3Net and Baikal-GVD, has unveiled a new view into the most extreme high-energy processes in the universe. As of 2024, nearly 300 astrophysical track-like TeV-PeV neutrino events have been detected, though their exact astrophysical counterparts remain largely unidentified, limited by the localization accuracy of current neutrino observatories. However, growing evidence suggests a strong association between these high-energy neutrinos and supermassive black holes with powerful relativistic jets. In this talk, I will review some leading astrophysical scenarios for high-energy neutrino production, highlighting recent multi-messenger approaches that combine neutrino detections with electromagnetic observations from radio to gamma-ray wavelengths. I will also present our ongoing studies using high-resolution very-long-baseline interferometric observations of IceCube neutrino fields to study candidate sources. Additionally, I will briefly introduce the Square Kilometer Array (SKA), an upcoming transformative radio telescope array that will enable high-resolution, real-time monitoring of the dynamic high-energy universe.

13 Low-acceleration gravitatioinal anomaly and its implications

The gravitational anomalies observed in galaxies and galaxy clusters based on standard gravity have been interpreted as the presence of dark matter. Internal orbital motions of nearby wide binaries (widely separated, long-period, gravitationally bound binary stars) are free from the effects of the inferred dark matter density in the Milky Way and thus can be used to directly probe low-acceleration gravity regardless of the dark matter concept. Several recently published and ongoing analyses of wide binaries from the Gaia DR3 database show clear evidence for gravitational anomaly in the low-acceleration regime (< 1 nanometer per second squared) that is equivalent to the acceleration regime for the gravitational anomaly in galaxy rotation curves.
Wide binary anomalies indicate that standard gravity is broken in the low-acceleration regime. Standard gravity satisfies the strong equivalence principle (SEP) beyond Galilei’s universality of free-fall (or the weak equivalence principle). Interestingly, the degree and trend of wide binary anomalies are consistent with the generic prediction of modified gravity theories such as AQUAL under Milgrom’s paradigm of modified Newtonian dynamics (MOND). MOND obeys the universality of free-fall but breaks the strong equivalence principle.
As long as the current evidence for wide binary gravitational anomalies is not a fluke, a new scientific revolution is inevitable. Einstein’s general relativity needs to be extended or replaced by a new theory. Astrophysical dynamics and cosmology based on general relativity or Newtonian dynamics require a major revision. The concept of unidentified dark matter needs to be rethought. I will show how future data and analyses can solidify the current evidence and make it a true scientific fact.

16 CO Intensity Mapping for Capturing the Star-formation History in the Early Universe

Line-intensity mapping (LIM) is an observational technique that has recently been actively used in astronomy and astrophysics research. LIM utilizes relatively small aperture telescopes to perform large-area surveys, effectively analyzing the brightness distribution of galaxies and intergalactic medium through their spectral line emissions. Probing astrophysics and cosmology using LIM has been gaining attention, with several experiments already in operation or planning deployments. Among these is the carbon monoxide (CO) Mapping Array Project (COMAP), which uses CO line emission to explore molecular gas that traces star formation. The COMAP Pathfinder currently observes at 26-34 GHz to measure the CO power spectrum at redshifts 2.4-3.4, near the peak of the star formation in cosmological history. In this presentation, I will provide an overview of COMAP's observational techniques and introduce the planned development of a prototype receiver that will be operating in the 12-20 GHz range to study the 115.27 GHz CO line emission originating from z=4.8-8.6 near the epoch of reionization.
