Origin of the UV to X-ray emission of radio galaxy NGC 1275 explored by analyzing its variability
Fumiya Imazato, Yasushi Fukazawa, Mahito Sasada +1
We analyze the ultraviolet (UV) and X-ray data of NGC 1275 obtained with {\it Swift}/UVOT, XRT, BAT and {\it Fermi} Large Area Telescope over about 10 years to investigate the orig…
XL-Calibur -- a second-generation balloon-borne hard X-ray polarimetry mission
Q. Abarr, H. Awaki, M. G. Baring +38
XL-Calibur is a hard X-ray (15-80 keV) polarimetry mission operating from a stabilised balloon-borne platform in the stratosphere. It builds on heritage from the X-Calibur mission,…
Calcium-rich Transient SN 2019ehk in A Star-Forming Environment: Yet Another Candidate for An Ultra-Stripped Envelope Supernova
Tatsuya Nakaoka, Keiichi Maeda, Masayuki Yamanaka +20
We present optical and near-infrared observations of SN~Ib~2019ehk. We show that it evolved to a Ca-rich transient according to its spectral properties and evolution in late phases…
Variations of the physical parameters of the blazar Mrk 421 based on the analysis of the spectral energy distributions
Yurika Yamada, Makoto Uemura, Ryosuke Itoh +3
We report on the variations of the physical parameters of the jet observed in the blazar Mrk 421, and discuss the origin of X-ray flares in the jet, based on the analysis of the se…
