Binary Interaction Can Yield a Diversity of Circumstellar Media around Type II Supernova Progenitors
Tomoki Matsuoka, Ryo Sawada
Recent observations of supernovae (SNe) have indicated that a fraction of massive stars possess dense circumstellar medium (CSM) at the moment of their core collapses. They suggest…
A Multi-Wavelength View on the Rapidly-Evolving Supernova 2018ivc: An Analog of SN IIb 1993J but Powered Primarily by Circumstellar Interaction
Keiichi Maeda, Poonam Chandra, Takashi J. Moriya +15
SN 2018ivc is an unusual type II supernova (SN II). It is a variant of SNe IIL, which might represent a transitional case between SNe IIP with a massive H-rich envelope, and IIb wi…
Long-term evolution of a supernova remnant hosting a double neutron star binary
Tomoki Matsuoka, Shiu-Hang Lee, Keiichi Maeda +2
An ultra-stripped supernova (USSN) is a type of core-collapse SN explosion proposed to be a candidate formation site of a double neutron star (DNS) binary. We investigate the dynam…
The final months of massive star evolution from the circumstellar environment around SN Ic 2020oi
Keiichi Maeda, Poonam Chandra, Tomoki Matsuoka +8
We present the results of ALMA band 3 observations of a nearby type Ic supernova (SN) 2020oi. Under the standard assumptions on the SN-circumstellar medium (CSM) interaction and th…
Radio Emission from Ultra-stripped Supernovae as Diagnostics for Properties of the Remnant Double Neutron Star Binaries
Tomoki Matsuoka, Keiichi Maeda
An ultra-stripped supernova (SN) is an explosion of a helium or C+O star whose outer envelope has been stripped away by a companion neutron star. A double neutron star (DNS) binary…
Radio Emission from Supernovae in the Very Early Phase: Implications for the Dynamical Mass Loss of Massive Stars
Tomoki Matsuoka, Keiichi Maeda, Shiu-Hang Lee +1
Recent high-cadence transient surveys and rapid follow-up observations indicate that some massive stars may dynamically lose their own mass within decades before supernovae (SNe).…
TeV gamma-ray observations of southern BL Lacs with the CANGAROO 3.8m Imaging Telescope
M. D. Roberts, S. A. Dazeley, P. G. Edwards +32
Observational and theoretical results indicate that low-redshift BL Lacertae objects are the most likely extragalactic sources to be detectable at TeV energies. In this paper we pr…
Discovery of TeV Gamma Rays from SN1006: Further Evidence for the SNR Origin of Cosmic Rays
T. Tanimori, Y. Hayami, S. Kamei +36
This paper reports the first discovery of TeV gamma-ray emission from a supernova remnant made with the CANGAROO 3.8 m Telescope. TeV gamma rays were detected at the sky position a…
Detection of Gamma Rays of Up to 50 TeV From the Crab Nebula
T. Tanimori, K. Sakurazawa, S. A. Dazeley +28
Gamma rays with energies greater than 7 TeV from the Crab pulsar/nebula have been observed at large zenith angles, using the Imaging Atmospheric Technique from Woomera, South Austr…
Very High Energy Gamma Rays from the Vela Pulsar Direction
T. Yoshikoshi, T. Kifune, S. A. Dazeley +29
We have observed the Vela pulsar region at TeV energies using the 3.8 m imaging Cherenkov telescope near Woomera, South Australia between January 1993 and March 1995. Evidence of a…
