X-rays breaking out of pre-explosion ejecta mark a supernova's first light
Weimin Yuan, Qiu-Ju Huang, Jin-Ping Zhu +130
Massive stars die as core-collapse supernovae, whose optical light emerges days after the implosion. Theory predicts that the initial collapse-driven shock, upon breaking through t…
Decadal pre-explosion activity and circumstellar interaction in a supernova
Ting-Wan Chen, Amar Aryan, Sheng Yang +52
When a massive star explodes as a supernova, crucial information about its immediate environment is lost within hours. Here we report rapid optical observations from Lulin Observat…
The Advanced X-ray Imaging Satellite (AXIS) Community Science Book
Michael Koss, Nafisa Aftab, Steven W. Allen +395
The AXIS Community Science Book represents the collective effort of 592 scientists worldwide to define the transformative science enabled by the Advanced X-ray Imaging Satellite (A…
Two Possible Optical--X-Ray Anti-Correlations of PSR J1023+0038
Ka-Yui Au, Kwan-Lok Li, Albert K. H. Kong +3
X-ray emission is generally believed to be one of the major heating sources for the optical modulation in redback pulsar binaries as we have seen similar phenomena in many low mass…
GeV-TeV Connections in Galaxies: Evolutionary Signatures from Pulsars in Globular Clusters
Ellis R. Owen, Yoshiyuki Inoue, Chung-Yue Hui +2
The dominant mechanisms underlying high-energy -ray emission from galaxies vary by galaxy type. In starbursts, a major contribution comes from neutral pion decay. This is drive…
Effectiveness of Stacks in the Stacked Hilbert-Huang Transform
Lupin Chun-Che Lin, Chin-Ping Hu, Chien-Chang Yen +6
The Hilbert-Huang transform (HHT) consists of empirical mode decomposition (EMD), which is a template-free method that represents the combination of different intrinsic modes on a…
