Exact Calculation of Nonideal Fields Demonstrates Dominance of Injection in Relativistic Reconnection
Samuel R. Totorica, Seiji Zenitani, Shuichi Matsukiyo +3
Magnetic reconnection is an important source of energetic particles in systems ranging from astrophysics to the laboratory. The large separation of spatiotemporal scales involved m…
Type Ia SN 2019ein: New Insights into the Similarities and diversities among High-Velocity SNe Ia
Miho Kawabata, Keiichi Maeda, Masayuki Yamanaka +38
We present optical observations of type Ia supernova (SN) 2019ein, starting at 2 days after the estimated explosion date. The spectra and the light curves show that SN 2019ein belo…
X-ray, Optical, and Near-infrared Monitoring of the New X-ray Transient MAXI J1820+070 in the Low/hard State
Megumi Shidatsu, Satoshi Nakahira, Satoshi Yamada +26
We report X-ray, optical, and near-infrared monitoring of the new X-ray transient MAXI J1820070 discovered with MAXI on 2018 March 11. Its X-ray intensity reached Crab…
Large Polarization Degree of Comet 2P/Encke Continuum Based on Spectropolarimetric Signals During Its 2017 Apparition
Y. G. Kwon, M. Ishiguro, Y. Shinnaka +16
Spectropolarimetry is a powerful technique for investigating the physical properties of gas and solid materials in cometary comae without mutual contamination, but there have been…
Broad-Lined Supernova 2016coi with Helium Envelope
Masayuki Yamanaka, Tatsuya Nakaoka, Masaomi Tanaka +38
We present the early-phase spectra and the light curves of the broad-lined supernova (SN) 2016coi from to days after the estimated explosion date. This SN was initially…
A New Constraint on the Ly Fraction of UV Very Bright Galaxies at Redshift 7
Hisanori Furusawa, Nobunari Kashikawa, Masakazu A. R. Kobayashi +15
We study the extent to which very bright (-23.0 < MUV < -21.75) Lyman-break selected galaxies at redshifts z~7 display detectable Lya emission. To explore this issue, we have obtai…
