Abstract We explore the validity of recently reported fundamental plane (FP) relation γ -ray pulsars using 190 included in latest 4FGL-DR3 catalog. This sample number is more than twice as large that original study. The FP incorporates four parameters, i.e., spin-down power, <mml:mover a...

The method of realizing certain self-reciprocal transforms as (absolute) scattering, previously presented in summarized form in the case of the Fourier cosine and sine transforms, is here applied to the self-reciprocal transform f(y) 7→ H(f)(x) = ∫∞ 0 J0(2 √ xy)f(y) dy, which is isometrically equivalent to the Hankel transform of order zero and is related to the functional equations of the Dede...

We compute the kinematical dependence of the peak luminosity, the pulse width and the spectral lag of the peak luminosity on the viewing angle θv of a jet. For appropriate model parameters we obtain the peak luminosity-spectral lag relation similar to the observed one including GRB980425. A bright (dim) peak with short (long) spectral lag corresponds to a jet with small (large) viewing angle. T...

The polarization of relativistic jets is of interest for the understanding of their origin, confinement, and propagation. However, even though numerous measurements have been performed, the mechanisms behind jet variability, creation, and composition are still debated. We have performed simultaneous gamma-ray and optical photopolarimetry observations of 45 blazars with the Kanata telescope sinc...

A few tight correlations linking several properties of gamma–ray bursts (GRBs), namely the spectral peak energy, the total radiated energy, and the afterglow break time, have been discovered with pre-Swift GRBs. They were used to constrain the cosmological parameters together with type-Ia supernovae. However, the tightness of these correlations is a challenge to GRB models. We explore the effec...

Two currently debated problems in galaxy evolution, the fundamentally local or global nature of main sequence star formation and evolution mass-size relation forming galaxies (SFGs), are shown to be intimately related each other. As a preliminary step, growth function $g$ is defined, which quantifies differential change half-mass radius per unit increase stellar mass ($g = d \log R_{1/2}/d M_\s...

The basolateral amygdala (BLA) mediates the facilitating effects of emotions on memory. The BLA’s enhancing influence extends to various types of memories, including striatal-dependent habit formation. To shed light on the underlying mechanisms, we carried out unit and local field potential (LFP) recordings in BLA, striatum, auditory cortex and intralaminar thalamus in cats trained on a stimulu...
