A Balloon-Borne Very Long Baseline Interferometry Experiment in the Stratosphere: Systems Design and Developments
Akihiro Doi, Yusuke Kono, Kimihiro Kimura +33
The balloon-borne very long baseline interferometry (VLBI) experiment is a technical feasibility study for performing radio interferometry in the stratosphere. The flight model has…
Detection of Coronal Magnetic Activity in Nearby Active Supermassive Black Holes
Yoshiyuki Inoue, Akihiro Doi
Central supermassive black holes of active galactic nuclei host hot plasma with a temperature of K, namely coronae. Like the Sun, black hole coronae are theoretically believ…
Detection of polarized gamma-ray emission from the Crab nebula with Hitomi Soft Gamma-ray Detector
Hitomi Collaboration, Felix Aharonian, Hiroki Akamatsu +191
We present the results from the Hitomi Soft Gamma-ray Detector (SGD) observation of the Crab nebula. The main part of SGD is a Compton camera, which in addition to being a spectrom…
High-energy neutrino flare from cloud-jet interaction in the blazar PKS 0502+049
Hao-Ning He, Yoshiyuki Inoue, Susumu Inoue +1
Following the detection of a 300 TeV neutrino potentially associated with the flaring blazar TXS 0506+056, an excess of neutrinos around its position in 2014-2015 was reveale…
Diffuse x-ray emission from the northern arc of loop I observed with suzaku
Masahiro Akita, Jun Kataoka, Makoto Arimoto +4
After discovery of the Fermi bubbles, giant structures observed in radio to X-rays have been discussed as possi- ble evidence of past activities in the Galactic Center (GC). We rep…
Spatial distribution of the Milky Way hot gaseous halo constrained by Suzaku X-ray observations
Shinya Nakashima, Yoshiyuki Inoue, Noriko Yamasaki +3
The formation mechanism of the hot gaseous halo associated with the Milky Way Galaxy is still under debate. We report new observational constraints on the gaseous halo using 107 li…
X-ray and Gamma-ray Observations of the Fermi Bubbles and NPS/Loop I Structures
Jun Kataoka, Yoshiaki Sofue, Yoshiyuki Inoue +3
The Fermi bubbles were possibly created by large injections of energy into the Galactic Center (GC), either by an active galactic nucleus (AGN) or by nuclear starburst more than ~1…
Hitomi X-ray Observation of the Pulsar Wind Nebula G21.50.9
Hitomi Collaboration, Felix Aharonian, Hiroki Akamatsu +194
We present results from the Hitomi X-ray observation of a young composite-type supernova remnant (SNR) G21.50.9, whose emission is dominated by the pulsar wind nebula (PWN) cont…
