X-ray Polarization of Inverse Compton Scattering by Thermal and Nonthermal Electrons

Boting Wang, Jirong Mao, Jieying Liu +1

X-ray emission from accretion-powered astrophysical systems is widely interpreted as inverse Compton (IC) scattering between energetic electrons and soft photons. Besides the emitt…

Gamma-ray signature of superluminous supernovae: Fermi-LAT GeV detection of SN 2017egm and evidence of a central engine

F. Acero, A. Acharyya, A. Adelfio +116

Superluminous supernovae (SLSNe) are a rare class of transients with peak luminosities 10-100 times greater than those of standard core-collapse supernovae (SNe). The mechanisms po…

A Radio Changing-state Jet in the Narrow-line Seyfert 1 Galaxy J1105+1452

Liming Dou, Zhining Chen, Jiahua Wu +9

We report the discovery of a radio-quiet to radio-loud transition in the narrow-line Seyfert 1 galaxy J1105+1452. The source has undergone a long-term evolution from a radio-quiet…

Spectral Dataset of Stripped-Envelope Supernovae from the Tsinghua Supernova Group

Danfeng Xiang, Xiaofeng Wang, Jujia Zhang +40

The extent of envelope stripping in the progenitor stars is directly reflected in the diversity of spectral features observed in stripped-envelope supernovae (SESNe). Through exten…

Multi-epoch afterglow rebrightenings in GRB 250129A: Evidence for successive shock interactions

D. Akl, S. Antier, H. Koehn +105

Most long gamma-ray bursts (GRBs) exhibit afterglows broadly consistent with external forward-shock emission, typically described by smooth broken power-law decays in the multiband…

The Gravitational-Wave Power Gap in Core-Collapse Supernovae: Insights from 60 Axisymmetric Simulations

Haakon Andresen, Xingzao Li, Aurore Betranhandy +3

We analyse the gravitational-wave emission from 60 two-dimensional core-collapse supernova simulations. The models cover a range of progenitors and equations of state. We focus on…
