29. What have we learned from 10 years of GW observations?

Hyung Mok Lee (Korea Astronomy and Space Science Institute)

6/10/26, 2:00 PM

The year 2025 marks ten years since the landmark detection of GW150914, which inaugurated gravitational-wave astronomy. Across four observing runs of the LIGO–Virgo–KAGRA (LVK) network, more than 300 events — primarily binary black hole mergers — have been detected, enabled by steady improvements in detector sensitivity and a rapidly expanding observable volume. These discoveries have reshaped...

34. Relativistic-like behavior of ALPs with non-relativistic momenta

Yuma Narita (Tohoku Univ.)

6/10/26, 4:45 PM

Axion-like particles (ALPs) are among the leading dark-matter candidates. In the minimal cosine potential, cosmology imposes a robust requirement: by the epoch when ALPs behave as matter, the potential height needs to exceed the ALP energy density. This translates into a lower bound on the decay constant. A plausible loophole is to store most of the energy in nonzero-momentum modes while...

35. Electromagnetic Signatures of Dark Matter in the Terrestrial Environment

Atsushi Taruya (Yukawa Institute for Theoretical Physics / Korea Institute for Advanced Study)

6/10/26, 5:00 PM

We present a novel framework to search for dark matter (DM) through its electromagnetic (EM) signatures in the terrestrial environment. Ultralight DM candidates, such as axions and dark photons, can induce nearly monochromatic EM fields via their coupling to ordinary photons. In the presence of the geomagnetic field, axion DM induces extremely low-frequency EM signals in the Earth–ionosphere...
