Abstract: The merger of two neutron stars is predicted to give rise to three major detectable phenomena: a short burst of γ-rays, a gravitational-wave signal, and a transient optical-near-infrared source powered by the synthesis of large amounts of very heavy elements via rapid neutron capture (the r-process). Such transients, named 'macronovae' or 'kilonovae', are believed to be centres of production of rare elements such as gold and platinum. The most compelling evidence so far for a kilonova was a very faint near-inf… Show more

“…The deep upper limit from Gemini shows that at ~10 days the afterglow became the dominant component and the kilonova already faded away. This is consistent with the behavior of AT2017gfo 8 , 10 , 20 , and predicted in general by kilonova models 13 , 29 , 30 .…”

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.

“…The light curves from our simulations have higher apparent magnitude compared to the previous results in Nativi et al ( 2021 ). The values presented in this paper are closer to the apparent magnitude observed for GW 170 817 KN AT2017gfo (Andreoni et al 2017 ;Arcavi et al 2017 ;Chornock et al 2017 ;Cowperthwaite et al 2017 ;Drout et al 2017 ;Evans et al 2017 ;Kasliwal et al 2017 ;Pian et al 2017 ;Smartt et al 2017 ;Tanvir et al 2017 ;Troja et al 2017 ;Utsumi et al 2017 ;Valenti et al 2017 ). In both cases, the variation with inclination angles is greatest for the Wind model.…”

“…5). This is consistent with previous findings suggesting that AT 2017gfo was observed at 15 • θ obs 30 • (0.87 cos θ obs 0.97) from the polar axis (Abbott et al 2017;Pian et al 2017;Troja et al 2017;Finstad et al 2018;Mandel 2018;Mooley et al 2018). The good agreement is especially true at bluer wavelengths (ugri).…”
