NICER observations reveal doubled timescales in Ansky's quasi-periodic eruptions (QPEs)

L. Hernández-García, P. Sánchez-Sáez, J. Chakraborty +11

Quasi-periodic eruptions (QPEs) are recurring X-ray bursts originating from the vicinity of supermassive black holes, but their driving mechanisms remain under debate. This study a…

Prospects for dark matter observations in dwarf spheroidal galaxies with the Cherenkov Telescope Array Observatory

K. Abe, S. Abe, J. Abhir +491

The dwarf spheroidal galaxies (dSphs) orbiting the Milky Way are widely regarded as systems supported by velocity dispersion against self-gravity, and as prime targets for the sear…

Multi-wavelength study of OT 081: broadband modelling of a transitional blazar

MAGIC Collaboration, H. Abe, S. Abe +270

OT 081 is a well-known, luminous blazar that is remarkably variable in many energy bands. We present the first broadband study of the source which includes very-high-energy (VHE, $…

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-…

BASS-XL: X-ray variability properties of unobscured Active Galactic Nuclei

Alessia Tortosa, Claudio Ricci, Patricia Arévalo +15

We investigate the X-ray variability properties of Seyfert1 Galaxies belonging to the BAT AGN Spectroscopic Survey (BASS). The sample includes 151 unobscured (N c…
