Abstract: Gravitational waves from a merger of two neutron stars (NSs) were discovered for the first time in GW170817, together with diverse electromagnetic (EM) counterparts. To make constraints on a relativistic jet from the NS merger, we calculate the EM signals in (1) the short gamma-ray burst sGRB 170817A from an off-axis jet, (2) the optical-infrared macronova (or kilonova), especially the blue macronova, from a jetpowered cocoon, and (3) the X-ray and radio afterglows from the interaction between the jet and inte… Show more

“…(iii) The jet head breakout velocity was constrained as 0.52 < v b /c < 1. This result is in agreement with Ioka & Nakamura (2018). This new constraint is more robust but in an overall agreement with previous studies (in agreement with Metzger et al 2018; partially in agreement with theoretical estimations based on numerical relativity simulations: Shibata et al 2017 andFujibayashi et al 2018).…”

Exaggerated anticipatory anxiety is common in social anxiety disorder (SAD). Neuroimaging studies have revealed altered neural activity in response to social stimuli in SAD, but fewer studies have examined neural activity during anticipation of feared social stimuli in SAD. The current study examined the time course and magnitude of activity in threat processing brain regions during speech anticipation in socially anxious individuals and healthy controls (HC). Method Participants (SAD n = 58; HC n = 16) underwent functional magnetic resonance imaging (fMRI) during which they completed a 90s control anticipation task and 90s speech anticipation task.

“…For the top-hat jet, the luminosity declines rapidly beyond the jet core due to the de-beaming effect (we can see a similar behavior for E γ,iso in Kasliwal et al 2017;Granot et al 2017;Ioka & Nakamura 2018). Since a wing component may dominate the emission outside of the core (Matsumoto et al 2019a;Ioka & Nakamura 2019), the observed luminosity becomes brighter for top-hat with a Gaussian wing jets (black) and for Gaussian jets (blue).…”

“…There have been numerous suggestions that dimmer and softer transients, for example low-luminosity GRBs (ll GRBs), are regular GRBs observed off-axis (e.g., Nakamura 1998;Eichler & Levinson 1999;Woosley et al 1999;Ioka & Nakamura 2001;Yamazaki et al 2003;Waxman 2004). Similar suggestions (Goldstein et al 2017;Murguia-Berthier et al 2017;Ioka & Nakamura 2018) were made shortly following the detection of the very weak short GRB (sGRB) 170817A (Abbott et al 2017b;Goldstein et al 2017;Savchenko et al 2017). However, these suggestions did not take into account the compactness problem (Kasliwal et al 2017).…”
