Energetic Nonthermal Electrons within the Above-the-looptop Regions in Solar Flares: Acceleration, Feedback, and Quasi-Periodic Pulsations
Jeongbhin Seo, Fan Guo, Xiaocan Li +3
Solar flares are among the most dramatic events in the solar system, releasing substantial magnetic energy and accelerating a large number of electrons to high energies. Notably, i…
VERITAS Limits on Dark Matter Annihilation in the Galactic Center Halo
A. Archer, P. Bangale, J. T. Bartkoske +58
Well-motivated models of particle dark matter predict its self-annihilation into Standard Model end states, which may be detected by particle detectors or telescopes. We conduct an…
A Self-Sustaining Black Hole Engine Powered by the Tidal Disruptions of Stars
James Guillochon, Avi Loeb
Tidal disruption events (TDEs) strongly prefer host galaxies undergoing, or recovering from, a burst of star formation, implying that a rare minority of galaxy types produces most…

Reverberation in the Narrow Fe K Line in the Seyfert Galaxy NGC 4151 with XRISM
Jon M. Miller, Aberahmen Zoghbi, Xin Xiang +11
Emission lines that "echo" variations in the ionizing flux produced close to black holes are powerful probes of the central engine. In the Seyfert-1.5 galaxy NGC 4151, high-resolut…
VLA Observations Confirm AT 2023mfm as an Off-nuclear Tidal Disruption Event
Wenkai Li, Collin T. Christy, Kate D. Alexander +15
We report new radio observations of the tidal disruption event (TDE) AT 2023mfm, which we identified as a high-confidence candidate in a systematic search for off-nuclear TDEs. Hig…
Resolving the temporal evolution of M87 jet with -arcsec Chandra observations
Camille Poitras, Gerrit Schellenberger, Ralph Kraft +3
We present a 13-year Chandra/HRC-I study of the M87 jet, using point-spread-function deconvolution to achieve unprecedented sub-arcsecond X-ray resolution of its kiloparsec-scale s…
The radio emission from radiative filaments of Cygnus Loop

The Galactic supernova remnant (SNR) Cygnus Loop emerges as an ideal laboratory for analyzing the different radiation mechanisms, as well as the particle acceleration mechanisms at…
IXPE Polarizations of the Lighthouse Pulsar, Trail, and Filament
Jack T. Dinsmore, Roger W. Romani, S. Zhang +9
The Lighthouse pulsar (PSR J11016101) sports a bright X-ray trail and filament. The synchrotron emission from both structures is expected to be polarized, with electric vector p…
Fifteen new millisecond pulsars in 47 Tucanae
W. Chen, D. Risbud, P. C. C. Freire +16
47 Tucanae is one of the largest, brightest, and closest globular clusters to Earth. It hosts an exotic stellar population with stellar dynamics that indicate a complex evolution h…
