Evidence for Rapid Adiabatic Cooling as an Origin of the Recombining Plasma in the Supernova Remnant W49B Revealed by NuSTAR Observations

Hiroya Yamaguchi, Takaaki Tanaka, Daniel R. Wik +8

X-ray observations of supernova remnants (SNRs) in the last decade have shown that the presence of recombining plasmas is somewhat common in a certain type of object. The SNR W49B…

K2 Observations of SN 2018oh Reveal a Two-Component Rising Light Curve for a Type Ia Supernova

G. Dimitriadis, R. J. Foley, A. Rest +145

We present an exquisite, 30-min cadence Kepler (K2) light curve of the Type Ia supernova (SN Ia) 2018oh (ASASSN-18bt), starting weeks before explosion, covering the moment of explo…

Kinematic links and the co-evolution of MHD winds, jets, and inner disks from a high-resolution optical [OI] survey

Andrea Banzatti, Ilaria Pascucci, Suzan Edwards +3

We present a survey of optical [OI] emission at 6300 Å toward 65 TTauri stars at the spectral resolution of km/s. Past work identified a highly blueshifted velocity compone…

NuSTAR Detection of Nonthermal Bremsstrahlung from the Supernova Remnant W49B

Takaaki Tanaka, Hiroya Yamaguchi, Daniel R. Wik +10

We report on NuSTAR observations of the mixed morphology supernova remnant (SNR) W49B, focusing on its nonthermal emission. Whereas radio observations as well as recent gamma-ray o…

Fast Radio Burst 121102 Pulse Detection and Periodicity: A Machine Learning Approach

Yunfan Gerry Zhang, Vishal Gajjar, Griffin Foster +4

We report the detection of 72 new pulses from the repeating fast radio burst FRB 121102 in Breakthrough Listen C-band (4-8 GHz) observations at the Green Bank Telescope. The new pu…

Detection of Bursts from FRB 121102 with the Effelsberg 100-m Radio Telescope at 5 GHz and the Role of Scintillation

Laura G Spitler, W Herrmann, Geoffrey C Bower +8

FRB 121102, the only repeating fast radio burst (FRB) known to date, was discovered at 1.4 GHz and shortly after the discovery of its repeating nature, detected up to 2.4 GHz. Here…

Seeing Double: ASASSN-18bt Exhibits a Two-Component Rise in the Early-Time K2 Light Curve

B. J. Shappee, T. W. -s. Holoien, M. R. Drout +109

On 2018 Feb. 4.41, the All-Sky Automated Survey for SuperNovae (ASAS-SN) discovered ASASSN-18bt in the K2 Campaign 16 field. With a redshift of z=0.01098 and a peak apparent magnit…

An extreme magneto-ionic environment associated with the fast radio burst source FRB 121102

D. Michilli, A. Seymour, J. W. T. Hessels +31

Fast radio bursts (FRBs) are millisecond-duration, extragalactic radio flashes of unknown physical origin. FRB 121102, the only known repeating FRB source, has been localized to a…
