Swope Supernova Survey 2017a (SSS17a), the optical counterpart to a gravitational wave source

Abstract: On 17 August 2017, the Laser Interferometer Gravitational-Wave Observatory (LIGO) and the Virgo interferometer detected gravitational waves (GWs) emanating from a binary neutron star merger, GW170817. Nearly simultaneously, the Fermi and INTEGRAL (INTErnational Gamma-Ray Astrophysics Laboratory) telescopes detected a gamma-ray transient, GRB 170817A. At 10.9 hours after the GW trigger, we discovered a transient and fading optical source, Swope Supernova Survey 2017a (SSS17a), coincident with GW170817. SSS17a i… Show more

“…Since these Eqs. (23), (24), and (25) are consistent with the observations, our results imply that the jet launch time t j is earlier than t br < ∆T 0 ∼ 2 s, and the delay time ∆T 0 ∼ 2 s of the γ-rays behind the GWs does not represent the jet launch time. This information is important for revealing the jet formation mechanism and could imply that a hypermassive NS formed from two NSs collapses to a BH earlier than ∼ 2 s after the NS merger.…”

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.

“…Adopting the νLν luminosity at epoch 1 of L43 = 7.8 × 10 38 erg s −1 and using an efficiency factor f = 0.1 (appropriate for te ≈ 30 days) implies an ejecta mass of Mej ≈ 1.6 − 7.8 × 10 −2 M . Within large uncertainties, the mass range is consistent with that inferred from analysis of early time observations of GW170817 (Coulter et al 2017;Drout et al 2017;Evans et al 2017;Kasliwal et al 2017;Smartt et al 2017;Soares-Santos et al 2017;Cowperthwaite et al 2017;Arcavi et al 2017), and provides additional evidence that the neutron star merger produced a large quantity of radioactive ejecta.…”
