Polarized Blazar X-rays imply particle acceleration in shocks

Kavli Affiliate: Grzegorz M. Madejski | First 5 Authors: Ioannis Liodakis, Alan P. Marscher, Iván Agudo, Andrei V. Berdyugin, Maria I. Bernardos | Summary: Blazars are active galactic nuclei that launch collimated, powerful jets of magnetized relativistic plasma. Their primary jet, whose emission typically spans from low-frequency radio to very high-energy ($gtrsim0.1$ TeV) $gamma$-rays (Blandford […]

Polarized Blazar X-rays imply particle acceleration in shocks

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Ioannis Liodakis, Alan P. Marscher, Iván Agudo, Andrei V. Berdyugin, Maria I. Bernardos | Summary: Most of the light from blazars, active galactic nuclei with jets of magnetized plasma that point nearly along the line of sight, is produced by high-energy particles, up to $sim 1$ […]

Categorical and K-theoretic Donaldson-Thomas theory of $mathbb{C}^3$ (part II)

Kavli Affiliate: Yukinobu Toda | First 5 Authors: Tudor Pădurariu, Yukinobu Toda, , , | Summary: Quasi-BPS categories appear as summands in semiorthogonal decompositions of DT categories for Hilbert schemes of points in the three dimensional affine space and in the categorical Hall algebra of the two dimensional affine space. In this paper, we prove […]

On Detecting Nearby Nano-Hertz Gravitational Wave Sources via Pulsar Timing Arrays

Kavli Affiliate: Qingjuan Yu | First 5 Authors: Xiao Guo, Youjun Lu, Qingjuan Yu, , | Summary: Massive binary black holes (MBBHs) in nearby galactic centers, if any, may be nano-Hertz gravitational wave (GW) sources for pulsar timing arrays (PTAs) to detect. Normally the objective GWs for PTA experiments are approximated as plane waves because […]

Measurement of the branching fractions and $CP$ asymmetries of $B^+ rightarrow π^+ π^0$ and $B^+ rightarrow K^+ π^0$ decays in 2019-2021 Belle II data

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, F. Abudinén, I. Adachi, K. Adamczyk, L. Aggarwal | Summary: We determine the branching fractions ${mathcal{B}}$ and $CP$ asymmetries ${mathcal{A}_{{it CP}}}$ of the decays $B^+ rightarrow pi^+ pi^0$ and $B^+ rightarrow K^+ pi^0$. The results are based on a data set containing 198 million […]

Gravitational waves from rapid structure formation on microscopic scales before matter-radiation equality

Kavli Affiliate: Misao Sasaki | First 5 Authors: Marcos M. Flores, Alexander Kusenko, Misao Sasaki, , | Summary: The existence of scalar fields can be probed by observations of stochastic gravitational waves. Scalar fields mediate attractive forces, usually stronger than gravity, on the length scales shorter than their Compton wavelengths, which can be non-negligible in […]
