Cosmology-Independent Constraints on Irreducible Magnetic Monopole Background
Syuhei Iguro, Varun Mathur, Ian M. Shoemaker +1
We present a novel mechanism for the irreducible production of magnetic monopoles from interactions of cosmic rays and interstellar medium (ISM). Resulting monopoles drain energy f…
Diffuse Neutrino Signals from Dark Stars Seeding Super-Massive Black Holes
Thomas Schwemberger, Volodymyr Takhistov
Dark stars (DSs) -- first stars powered by dark-matter (DM) heating rather than fusion -- could form in the early Universe. They can grow to masses and col…
Primordial Black Hole Mergers as Probes of Dark Matter in Galactic Center
Qianhang Ding, Minxi He, Volodymyr Takhistov
Primordial black holes (PBHs) from the early Universe that can contribute to dark matter (DM) abundance have been linked to gravitational wave observations. Super-massive black hol…
Dual Gravitational Wave Signatures of Instant Preheating
Wei-Yu Hu, Kazunori Nakayama, Volodymyr Takhistov +1
In the instant preheating scenario efficient particle production occurs immediately following the period of inflationary expansion in the early Universe. We demonstrate that instan…
Phase Separation Unlocks Resonant Leptogenesis
Jason Arakawa, Philip Lu, Volodymyr Takhistov
Distinct behavior of decaying particles in true and false vacua of the theory can lead to enhanced generation of baryon asymmetry, a scenario we call \textit{phase separation baryo…
Unlocking Discovery Potential for Decaying Dark Matter and Faint X-ray Sources with XRISM
Yu Zhou, Volodymyr Takhistov, Kazuhisa Mitsuda
Astrophysical emission lines arising from particle decays can offer unique insights into the nature of dark matter (DM). Using dedicated simulations with background and foreground…
Development of a data overflow protection system for Super-Kamiokande to maximize data from nearby supernovae
M. Mori, K. Abe, Y. Hayato +252
Neutrinos from very nearby supernovae, such as Betelgeuse, are expected to generate more than ten million events over 10\,s in Super-Kamokande (SK). At such large event rates, the…
Energy-dependent Boosted Dark Matter from Diffuse Supernova Neutrino Background
Anirban Das, Tim Herbermann, Manibrata Sen +1
Diffuse neutrinos from past supernovae in the Universe present us with a unique opportunity to test dark matter (DM) interactions. These neutrinos can scatter and boost the DM part…
Gravitational Wave Probe of Planck-scale Physics After Inflation
Weiyu Hu, Kazunori Nakayama, Volodymyr Takhistov +1
Particle decays are always accompanied by the emission of graviton quanta of gravity through bremsstrahlung processes. However, the corresponding branching ratio is suppressed by t…
Bosenovae with Quadratically-Coupled Scalars in Quantum Sensing Experiments
Jason Arakawa, Muhammad H. Zaheer, Joshua Eby +2
Ultralight dark matter (ULDM) particles of mass can form boson stars in DM halos. Collapse of boson stars leads to explosive bosenova emission of copious r…
