Constraints on Annihilating Dark Matter from Gamma-Ray Background-Galaxy Shape Correlations: Model-independent Null Results and Moderate Template-based Signals
Masato Shirasaki, Deheng Song, Oscar Macias +2
The paper uses cross‑correlations between the unresolved gamma‑ray background measured by Fermi‑LAT and galaxy shape data from DES Y3 and DECADE to place limits on dark‑matter anni…
The Cosmic Neutrino Background is within Reach of Future Neutrino Telescopes
Gonzalo Herrera, Shunsaku Horiuchi, Xiaolin Qi +1
The cosmic neutrino background (CB) can be boosted to high energies due to scatterings with energetic cosmic rays (CRs) across cosmological scales. Previous calculations focuse…
Ultra high-energy cosmic rays from relativistic outflows in accretion induced collapse of white dwarfs
Mainak Mukhopadhyay, Shunsaku Horiuchi
When a rapidly-rotating, highly magnetized white dwarf (WD) approaches the Chandrashekhar limit through mass accretion, it can undergo an accretion-induced collapse (AIC) to form a…
Ultraheavy Ultrahigh-Energy Cosmic Rays
B. Theodore Zhang, Kohta Murase, Nick Ekanger +2
We investigate the propagation of ultraheavy (UH) nuclei as ultrahigh-energy cosmic rays (UHECRs). We show that their energy loss lengths at EeV are significantly lon…
Survival of ultraheavy nuclei in astrophysical sources: applications to protomagnetar outflows
Nick Ekanger, Mukul Bhattacharya, Kohta Murase +1
Outflows of rapidly rotating protomagnetars have been considered as attractive sites for the synthesis of nuclei heavier than iron, but the question remains whether these nuclei ar…
Novel method to trace the dark matter density profile around supermassive black holes with AGN reverberation mapping
Mayank Sharma, Gonzalo Herrera, Nahum Arav +1
We propose a new method to determine the dark matter density profile in the vicinity of distant supermassive black holes (SMBH) using reverberation mapping (RM) measurements of act…
