A polarized view of the young Pulsar Wind Nebula 3C 58 with IXPE
N. Bucciantini, J. Wong, R. W. Romani +11
Pulsar Wind nebulae (PWNe), are among the most efficient particle accelerators in the Universe, however understanding the physical conditions and the magnetic geometry in their inn…
EP 250108a/SN 2025kg: Observations of the most nearby Broad-Line Type Ic Supernova following an Einstein Probe Fast X-ray Transient
J. C. Rastinejad, A. J. Levan, P. G. Jonker +66
With a small sample of fast X-ray transients (FXTs) with multi-wavelength counterparts discovered to date, the progenitors of FXTs and their connections to gamma-ray bursts (GRBs)…
An Intermediate-mass Black Hole Lurking in A Galactic Halo Caught Alive during Outburst
C. -C. Jin, D. -Y. Li, N. Jiang +137
Stellar-mass and supermassive black holes abound in the Universe, whereas intermediate-mass black holes (IMBHs) of ~10^2-10^5 solar masses in between are largely missing observatio…
A fast X-ray transient from a weak relativistic jet associated with a type Ic-BL supernova
H. Sun, W. -X. Li, L. -D. Liu +163
Massive stars end their lives as core-collapse supernovae, amongst which some extremes are broad-lined type Ic supernovae from Wolf-Rayet stars associated with long-duration gamma-…
Soft X-ray prompt emission from a high-redshift gamma-ray burst EP240315a
Y. Liu, H. Sun, D. Xu +191
Long gamma-ray bursts (GRBs) are believed to originate from core collapse of massive stars. High-redshift GRBs can probe the star formation and reionization history of the early un…
Recovery of the X-ray polarisation of Swift J1727.81613 after the soft-to-hard spectral transition
J. Podgorný, J. Svoboda, M. Dovčiak +34
We report on the detection of X-ray polarisation in the black-hole X-ray binary Swift J1727.81613 during its dim hard spectral state by the Imaging X-ray Polarimetry Explorer (I…
Discovery of oscillations above 200 keV in a black hole X-ray binary with Insight-HXMT
Xiang Ma, Lian Tao, Shuang-Nan Zhang +119
Low-frequency quasi-periodic oscillations (LFQPOs) are commonly found in black hole X-ray binaries, and their origin is still under debate. The properties of LFQPOs at high energie…
Unveiling recurrent jets of the ULX Holmberg II X-1: evidence for a massive stellar-mass black hole?
D. Cseh, P. Kaaret, S. Corbel +10
We report on the discovery of an apparent triple radio structure hidden inside the radio bubble of the ultraluminous X-ray source Holmberg II X-1. The morphology is consistent with…
Swift observations of the ultraluminous X-ray source Holmberg IX X-1
A. K. H. Kong, Y. J. Yang, T. -C. Yen +2
Holmberg IX X-1 is a well-known ultraluminous X-ray source with an X-ray luminosity of ~1e40 erg/s. The source has been monitored by the X-ray Telescope of Swift regularly. Since 2…
