arXiv.org | Quantum Field Theory Of Cosmological Perturbations Induced By Ultralight Dark Matter
Tomislav Prokopec, Marco Vecchioni · 4h ago · 3 min read
The growth of primordial perturbations during the matter-dominated era is primarily driven by dark matter. Ultralight scalar fields (ULDM) are a promising candidate for this role, conventionally modeled as operating in a classical, high-occupation regime. In this work, we develop a first-principles field-theoretic framework to investigate the impact of UL...

arXiv.org | Axion Misalignment Across First-Order Phase Transitions
Galymzhan Baltabay, Francesco D'Eramo, Ville Vaskonen · 4h ago · 3 min read
When the axion mass is generated during a first-order phase transition and becomes non-vanishing only inside expanding true-vacuum bubbles, the standard picture of misalignment production is qualitatively modified. Using lattice simulations in an expanding universe, we study dark matter production within such a framework and identify two distinct regimes....

arXiv.org | Collider Probes of Dark Energy Microphysics
4h ago · 3 min read
The physical origin of dark energy remains one of the most profound open questions in modern physics. Although cosmological observations tightly constrain the equation of state parameter $w$, this information alone does not reveal the underlying microphysics, as many distinct theoretical models can reproduce the same expansion history. A key discriminator...

The weathering of iron-rich phases within meteorites is a multi-stage process that significantly alters the microstructure and chemical composition based both on the environmental condition at the location of landing and the exposure time since the fall. This work investigates the resulting phases of this process in a correlative and comparative manner us...

arXiv.org | Cosmic Rays as an Interdisciplinary Earth Observation Tool: From Particle Physics and Atmospheric Processes to Geosciences and Urban Science
Bugra Bilin, Nuhcan Ak\c{c}it · 4h ago · 3 min read
The exploration of cosmic rays, which are high-energy particles originating from space and the atmosphere, has historically been associated with particle physics and astrophysics. In the last 20 years, these particles have evolved into valuable tools for observing Earth's systems. This review compiles the use of cosmic rays in three primary areas: (1) par...

Möbius-ring resonators stem from a well-studied geometrical structure with a one-sided topology, the Möbius strip, and have been shown to exhibit fermion rotational symmetry with respect to an untwisted ring resonator, which exhibits boson rotational symmetry [1]. Here, we present twisted hollow resonators with equilateral triangular cross-sections, leadi...

Artificial warming via engineered aerosols presents a novel pathway to bypass volatile scarcity on modern Mars. Utilizing the Generic Planetary Climate Model, we evaluate the physical feasibility of aerosol-induced terraforming over a full Martian year (669 Sols).

arXiv.org | Scaling Up: A Global Optical/X-ray Correlation For Reprocessing Across Black Hole Masses

This study extends the optical/X-ray correlation from black hole low-mass X-ray binaries (XRBs) to active galactic nuclei (AGN), bridging scales from stellar-mass to supermassive black holes (SMBHs). In XRBs, optical emission predominantly originates from the thermal reprocessing of high-energy photons on the surface of the geometrically thin, optically t...

arXiv.org | How much can shape degeneracies affect the Hubble constant measurement?
4h ago · 3 min read
Cluster lens models are constrained almost entirely by observed lensed image positions, leaving a large space of mass perturbations with arbitrary amplitudes such that they reproduce every image exactly. Such degeneracies are known as shape degeneracies (ShaDes). We show that these ShaDes shift the observed time delays, by the difference of the perturbing...

arXiv.org | Axial-Dipole and Equatorial-Dipole Coronal Holes: Congruent Magnetic Geometry, Divergent Evolution

While the Sun's polar fields reverse, the axial dipole is weak and low-latitude coronal holes are common. Equatorial-dipole coronal holes (EDCHs) appear when the equatorial dipole is strong, forming at its magnetic poles, similar to the axial-dipole coronal holes (ADCHs) of minimum. Not every low-latitude hole qualifies: the 2024 maximum was quadrupole-le...

A groundbreaking study suggests that 2.22 million Indigenous Australians lived on the continent before European colonization, far more than previously believed. Researchers estimate that 93% of this population was lost within 73 years, revealing a demographic catastrophe on a scale that dramatically changes our understanding of Australian history.
