Hydrodynamics of microalgae in sea spray

Airborne transmission of biological matter is likely to cause numerous respiratory distress in coastal populations during certain harmful algal blooms. While we know that dissolved algal toxins aerosolize, the contribution of particle-associated toxins is stil...

Data-driven and physics-guided hindcasting of measured wave spectra

Short-range hindcasts of measured wave spectra are evaluated using a recurrent model initialized by one hourly buoy spectrum and supplied with local wind, fetch and depth. Measurements from three Baltic Sea stations are combined for training in 2017--2020, val...

Tropical Cyclone Attributes in Sparse Autoencoder Features of an AI Weather Model

Artificial intelligence (AI) weather models now forecast weather events skillfully, but how they represent these events internally remains unknown. Sparse autoencoders (SAEs) provide sparse features for probing hidden states, but how information about multiple...

On Particle Production from Bubble Collisions in the Non-runaway Regime

Particle production from bubble collisions during First-Order Phase Transitions (FOPTs) has been studied as an efficient mechanism for baryogenesis and dark matter production, but existing semi-analytical treatments assume runaway bubbles with wall velocity $v...

Gravitational Waves from New Inflation

Gravitational waves provide one of the most powerful observational probes for discriminating among inflationary models. In particular, it has recently become clear that the high-frequency gravitational-wave spectrum encodes a wealth of information about the pr...

Testing Dynamical Dark-Energy Model with Standard Sirens

Bright standard sirens from the Einstein Telescope (ET) provide an independent probe of cosmic expansion. In this article, we test whether future ET observations can constrain a dynamical dark-energy scenario inspired by DESI DR2. Using the best-fitting 29-bin...

Alleviating CMB-BAO tension with a large cosmic birefringence angle during reionization induced by energy injection to axion-like particles

The recent measurement of baryon acoustic oscillations by the Dark Energy Spectroscopic Instrument reveals a mild tension with observations of the cosmic microwave background (CMB) within the standard $Λ$CDM cosmological model. Another interesting hint beyond...

OGLE-2013-BLG-1125/MOA-2013-BLG-584: Discovery of a gas giant orbiting an M dwarf

We report the discovery and characterization of a planetary system in the microlensing event OGLE-2013-BLG-1125/MOA-2013-BLG-584. We analyze photometric data from OGLE and MOA surveys, as well as LCO, $μ$FUN, and Mindstep follow-up telescopes to model the micr...
